From the cybersecurity policy and law enforcement front,

  • Cybersecurity Dive reports,
    • “U.S. government officials said critical infrastructure operators should be on alert for Iranian cyberattacks.
    • “In a threat advisory published Monday [June 30], multiple agencies said Iran might target U.S. firms “for near-term cyber operations” due to “the current geopolitical environment” — a reference to the Trump administration joining Israel’s aerial campaign against Iran’s nuclear program and related assets.
    • “Defense contractors, especially firms that have relationships with Israeli companies, are likely at heightened risk of targeting, according to the advisory.”
  • and
    • “The Department of Justice on Monday [June 30] announced a series of actions as part of an investigation into the North Korean government’s deployment of its citizens abroad to pose as IT workers and illicitly earn money for the regime.
    • “Newly unsealed charging documents describe two separate schemes to trick U.S. companies into hiring people who funneled their paychecks to the North Korean government and exploited their access to the companies’ networks to steal sensitive information and cryptocurrency.
    • “Law enforcement officials, who have repeatedly issued alerts about Pyongyang’s IT worker schemes, warned U.S. businesses on Monday to carefully screen their remote employees to avoid falling victim to similar ruses.
  • Cyberscoop tells us,
    • “The Chinese hackers behind the massive telecommunications sector breach are “largely contained” and “dormant” in the networks, “locked into the location they’re in” and “not actively infiltrating information,” the top FBI cyber official told CyberScoop.
    • “But Brett Leatherman, new leader of the FBI Cyber division, said in a recent interview that doesn’t mean the hackers, known as Salt Typhoon, no longer pose a threat.
    • “While there’s been some debate about whether Salt Typhoon should be getting more attention than fellow Chinese hackers Volt Typhoon — whom federal officials have said are prepositioned in U.S. critical infrastructure, poised for destructive action in the event of a conflict with the United States — Leatherman said the groups aren’t as different as some think.
    • “Salt Typhoon, even though it was [an] espionage campaign, had access to telecommunications infrastructure,” he said. “You can pivot from access in support of espionage to access in support of destructive action.”
  • and
    • “Federal authorities levied sanctions Tuesday on Aeza Group, a bulletproof hosting service provider based in Russia, for allegedly supporting a broad swath of ransomware, malware and infostealer operators.
    • “Aeza Group has provided servers and specialized infrastructure to the Meduza, RedLine and Lumma infostealer operators, BianLian ransomware and BlackSprut, a Russian marketplace for illicit drugs, according to the Treasury Department’s Office of Foreign Assets Control. Lumma infected about 10 million systems before it was dismantled through a coordinated global takedown in May.
    • “The Treasury Department’s action against Aeza Group follows a wave of cybercrime crackdowns across the globe. Prolific cybercriminals have been arrested, and infostealers, malware loaders, counter antivirus and crypting services, cybercrime marketplaces, ransomware infrastructure and DDoS-for-hire operations have all been seized, taken offline or severely disrupted by global coordinated campaigns since May.
    • “Officials accused Aeza Group of helping cybercriminals target U.S. defense companies and technology vendors.”

From the cybersecurity breaches and vulnerabilities front,

  • Cybersecurity Dive informs us,
    • “Australian carrier Qantas said hackers who breached one of its call centers stole a significant quantity of customer data.
    • “The airline said on its website that it detected unusual activity on Monday [June 30] on a third-party platform that one of its call centers used. The airline took immediate action and was able to contain the attack, which it blamed on a criminal hacker.
    • “Qantas said it is investigating the extent of the intrusion but warned that the hackers accessed a “significant” amount of customer data, including names, addresses, phone numbers, dates of birth and frequent-flyer numbers. 
    • “The breach did not compromise any credit card details, personal financial information or passport information, Qantas said, because those are stored in a separate system. The intrusion also did not expect login information for customers’ frequent-flyer accounts.
    • “Qantas said it was working with government authorities, including the Australian Cyber Security Centre and the National Cyber Security Coordinator, as well as independent forensic experts to investigate the breach.
    • “All of Qantas’ systems are now secure and the airline is operating normally, according to the company. It said it was in the process of contacting customers to alert them to the incident.” 
  • Per Security Week,
    • “Missouri healthcare provider Esse Health is notifying over 263,000 people that their personal information was stolen in a disruptive April 2025 cyberattack.
    • “The incident was discovered on April 21 and impacted the organization’s access to the electronic medical record system, while also taking down its phone system.
    • “By May 13, the healthcare provider had restored certain systems and was able to fulfill scheduled appointments or procedures. The phone systems were restored in early June, along with other primary patient-facing network systems, the organization said in an incident notice.
    • “On June 20, Esse Health said its investigation into the attack determined that a threat actor breached its network on April 21 and stole files containing personal information.
    • “The exfiltrated data included names, addresses, dates of birth, Social Security numbers, medical record numbers, patient account numbers, health information, and health insurance details.”
  • and
    • “Benefits and payroll solutions firm Kelly & Associates Insurance Group (dba Kelly Benefits) has informed authorities that a recent data breach impacts more than 550,000 people.
    • “The company revealed in April that hackers had gained access to its systems in December 2024, and an investigation had shown that the threat actor managed to steal files storing personal information.
    • “The incident resulted in the theft of information such as name, date of birth, Social Security number, tax ID number, medical information, health insurance information, and financial account information. 
    • “Kelly Benefits is notifying impacted individuals on behalf of more than 40 affected customers, including Aetna Life Insurance Company, Amergis, Beam Benefits, Beltway Companies, CareFirst, The Guardian Life Insurance Company of America, Fidelity Building Services Group, Intercon Truck of Baltimore, Humana Insurance ACE, Merritt Group, Publishers Circulation Fulfilment, Quantum Real Estate Management, United Healthcare, and Transforming Lives.
    • “Data breach reports submitted by Kelly Benefits to the Maine Attorney General’s Office since early April show that the number of impacted individuals has steadily increased as the company’s investigation progressed.” 
  • The Center for Medicare and Medicaid Services announced on June 30,
    • The Centers for Medicare & Medicaid Services (CMS) is notifying Medicare beneficiaries whose personal information may have been involved in a data incident affecting Medicare.gov accounts. CMS identified suspicious activity related to unauthorized creation of certain beneficiary online accounts using personal information obtained from unknown external sources. CMS takes this situation very seriously. The safeguarding and security of personally identifiable information is of the utmost importance to CMS. 
    • Following detection of the incident, CMS worked quickly to deactivate affected accounts, assess the scope and impact of the compromise, and mitigate the effects on impacted individuals. CMS is working closely with appropriate parties to investigate this situation.
    • Approximately 103,000 beneficiaries may have been impacted. Notifications to affected individuals are being mailed, informing them of the incident, outlining steps being taken to protect their information, and providing guidance on actions they may wish to take. 
  • The Cybersecurity and Infrastructure Security Agency added five known exploited vulnerabilities to its catalog this week.
  • Dark Reading warns
    • “While browser extensions add useful functionality to Web browsers, such as blocking ads, managing passwords, and taking notes, they also increase the organization’s security and privacy risks.
    • “Browser extensions require certain levels of permissions that are attractive to attackers. Some extensions need access to the user’s location, browsing history, or the user’s clipboard to see what data the user has copied. Some extensions go further, requesting access to nearly all of the data stored on the user’s computer as well as the data accessed while visiting different websites. Attackers can exploit extensions with these heightened permissions to access potentially sensitive information, such as Web traffic, saved credentials, and session cookies.
    • “Even extensions with relatively modest permissions can manipulate those permissions to obtain access to the inner workings of every Web page displayed on a user’s screen, warns LayerX CEO and co-founder Or Eshed. LayerX research shows that 53% of enterprise users have installed extensions labeled with “high” or “critical” permissions scope. This is why browser extensions are a prime avenue for exploitation by threat actors, he adds.  
    • “[Attackers] can use it to copy or rewrite data or exploit Web page permissions for even more access,” Eshed says.”
  • Security Week adds,
    • A vulnerability in the Forminator WordPress plugin could allow attackers to take over more than 400,000 impacted websites.
    • A popular form builder plugin with more than 600,000 active installations, Forminator supports the creation of various types of forms, including contact and payment forms, polls, and more.
    • The WordPress plugin was found vulnerable to CVE-2025-6463 (CVSS score of 8.8), an arbitrary file deletion flaw that exists because file paths are not sufficiently validated in a function used to delete a form submission’s uploaded files.

From the ransomware front,

  • Bleeping Computer reports,
    • “The Hunters International Ransomware-as-a-Service (RaaS) operation announced today that it has officially closed down its operations and will offer free decryptors to help victims recover their data without paying a ransom.
    • “After careful consideration and in light of recent developments, we have decided to close the Hunters International project. This decision was not made lightly, and we recognize the impact it has on the organizations we have interacted with,” the cybercrime gang says in a statement published on its dark web leak earlier today.
    • “As a gesture of goodwill and to assist those affected by our previous activities, we are offering free decryption software to all companies that have been impacted by our ransomware. Our goal is to ensure that you can recover your encrypted data without the burden of paying ransoms.” * * *
    • “Threat intelligence firm Group-IB also revealed in April that Hunters International was rebranding with plans to focus on data theft and extortion-only attacks and had launched a new extortion-only operation known as “World Leaks.”
  • Security Week advises,
    • The key tool for surviving ransomware, or any attack scenario, is an IR plan. But an IR plan is only worthwhile if it’s comprehensive, current, and tested. IR plans are not “best practices”, nor singular documents stored in a safe place. They are living resources that require attention and maintenance. In this way, the proof of an IR plan’s efficacy is in that organizational muscle memory – most effectively trained through Tabletop exercises.  So, what are the primary “muscles,” and the repetitive “exercises” in which you can train an organization to respond decisively, immediately, confidently, and automatically.”

From the cybersecurity defenses and business front,

  • Withum offers guidance on how to align your firm’s cybersecurity practices with Labor Department best practices for ERISA plan fiduciaries.
  • Per Security Week,
    • Cloudflare has reversed its block on AI-crawling from optional to default, allowing finer grained crawling but only with agreement from all parties concerned.
    • LLMs are what they learn. From their inception the biggest source of learning has been the internet, so there has been a natural tendency for AI developers to scrape the internet as widely as possible.
    • Cloudflare has now introduced an option for their customers to accept or reject website scraping by AI vendors. Hitherto, internet scraping has been a major part of gathering training data for large LLM (gen-AI) developers; but the process has raised questions and objections over legality, copyright infringement, and accuracy.
  • Dark Reading lets us know,
    • “How businesses can align cyber defenses with real threats. Companies that understand the motivations of their attackers and position themselves ahead of the competition will be in the best place to protect their business operations, brand reputation, and their bottom line.”
  • and
    • “One year after a buggy CrowdStrike update knocked IT systems offline, organizations seeking to strike the right balance between security and productivity have viewed the incident as a learning opportunity.
    • “The cost of the CrowdStrike outage was estimated at $5.4 billion, affecting payment systems, airline reservations, and a variety of other industries. The impact of the outage highlights why many operational technology (OT) teams are as sensitive to patches and other updates in their critical infrastructure, as they are highly averse to outages that can happen if such updates are defective.
    • “But when balancing security and productivity, it is imperative not to view the CrowdStrike outage as a reason to forgo patching completely. The ever-growing volume of vulnerabilities and threats requires organizations to remain resilient and anti-fragile — that is, to have the ability to proactively respond to issues and continuously improve.”
  • Per Security Week,
    • “LevelBlue announced on Tuesday [July 1] that it’s acquiring managed detection and response (MDR) services company Trustwave from The Chertoff Group’s MC² Security Fund.
    • “LevelBlue, formerly known as AT&T Cybersecurity, was launched in May 2024 as a joint venture between WillJam Ventures and AT&T. 
    • “The company’s acquisition of Trustwave comes shortly after it announced plans to buy Aon’s cybersecurity consulting business. The deals are part of a plan to become the largest pure-play managed security services provider (MSSP). 
    • “Once the acquisition has been completed, LevelBlue’s expertise in strategic risk management and cybersecurity infrastructure will be integrated with Trustwave’s platform and MDR service.”

From the cybersecurity policy and law enforcement front,

  • Federal News Network reports,
    • “House appropriators have advanced a homeland security spending bill that endorses many of the Trump administration’s budget proposals, while rejecting steep cuts to cybersecurity and artificial intelligence personnel.
    • “The fiscal 2026 homeland security appropriations measure includes $66.36 billion in discretionary spending. The GOP-led committee passed the bill Tuesday [June 24, 2025] on a 36-27 vote.
    • “The bill follows the broad contours of Trump administration policies by prioritizing funding for Customs and Border Protection and Immigration and Customs Enforcement. Appropriators are also expecting significant funding for the Department of Homeland Security to be included in the budget reconciliation bill.”
  • Cyberscoop tells us,
    • “With time running short before expiration of a cyber information-sharing law highly valued by the private sector, Congress is taking a look at the possibility of a short-term extension.
    • “The 2015 Cybersecurity Information Sharing Act, which provided legal safeguards for companies to share threat data, is due to sunset at the end of September, and Congress doesn’t tend to work much in August.
    • “A bipartisan pair of senators have introduced a bill to simply extend it for another 10 years. But a House bill is still in the works and might take a different approach that involves making changes to the law going forward, industry officials told CyberScoop on Wednesday. Getting competing proposals through both chambers, then settling differences and finalizing a bill to get to the president’s desk, could take significant time.
    • “There are other things that are being considered in the mix,” said John Miller, senior vice president of policy for trust, data and technology and general counsel at the Information Technology Industry Council. One would be attaching language to a continuing resolution funding measure that would extend the 2015 law for a short period of time.”
  • Cybersecurity Dive informs us,
    • “Federal officials and private-sector security leaders said Tuesday [June 24, 2025] that they are closely monitoring for cyberattacks related to the Iran conflict but thus far have not observed any significant activity. 
    • “The Department of Homeland Security warned Sunday that Iran-linked actors or hacktivist groups may launch attacks against U.S. critical infrastructure operators, citing a recent history of attacks against poorly configured water utilities and other systems. 
    • “An apparent truce announced late Monday by President Donald Trump appeared to lower international tensions, but officials remain on guard for any potential threat activity.
    • “The Cybersecurity and Infrastructure Security Agency (CISA) “is actively coordinating with government, industry, and international partners to share actionable intelligence and strengthen collective defense,” CISA spokesperson Marci McCarthy said in a statement. “There are currently no specific credible threats against the homeland.”
  • NextGov/FCW notes,
    • “Morgan Adamski is leaving her role as executive director of U.S. Cyber Command, handing the reins to Patrick Ware.
    • “After 17 years of service at the National Security Agency, I’ve decided to turn the page to an exciting new chapter in my career. It has been an extraordinary journey contributing to the defense of our Nation and advancing the cybersecurity mission across the U.S. Government,” Adamski wrote in a LinkedIn post Friday [June 27, 2025].
    • “The number three spot in the combatant command is typically held by a civilian on detail from the National Security Agency.
    • “Though Adamski did not clarify where she would be headed next, she noted her commitment to ensuring there were cyber solutions on “both sides of the fence.”
  • CISA and the National Security Agency have released a report titled “Memory Safe Languages: Reducing Vulnerabilities in Modern Software Development.’
  • Per Cyberscoop,
    • Kai West, a prolific cybercriminal better known for operating under the moniker “IntelBroker,” was arrested in France earlier this year and faces federal charges for allegedly stealing data from more than 40 organizations during a two-year period, the Justice Department said Wednesday [June 25, 2025]. 
    • Federal prosecutors unsealed a four-count indictment charging West, a British national, with conspiracy to commit computer intrusions, accessing a protected computer to obtain information and wire fraud. The United States is seeking his extradition for the charges, which each carry maximum sentences of five to 20 years in prison. 

From the cybersecurity breaches and vulnerabilities front,

  • Beckers Health IT identifies the top ten states for healthcare data breaches between February 2023 and April 2025.
  • CISA added three known exploited vulnerabilities to its catalog this week.

        • Cybersecurity News discusses this KVE here.
  • Cyberscoop reports,
    • Citrix on Wednesday [June 25, 2025] disclosed an actively exploited zero-day vulnerability affecting multiple versions of NetScaler products, an alarming development from a vendor that’s been widely targeted in previous attack sprees.
    • The zero-day (CVE-2025-6543) was disclosed by Citrix nine days after it issued a security bulletin for a pair of defects (CVE-2025-5777 and CVE-2025-5349) in the same products. All three vulnerabilities affect the company’s networking security appliance NetScaler ADC and its virtual private network NetScaler Gateway. 
    • “Exploits of CVE-2025-6543 on unmitigated appliances have been observed,” Citrix said in a security bulletin for the zero-day. Citrix did not respond to a request for comment. 
    • Citrix described the critical zero-day CVE-2025-6543, which has a base score of 9.2 on the CVSS scale, as a memory overflow defect that attackers can exploit for unintended control flow and denial of service. Exploitation can only occur if targeted NetScaler instances are configured as a gateway or an authentication, authorization and accounting (AAA) virtual server, according to Citrix.”
  • and
    • “The aviation industry has seemingly become the latest target of Scattered Spider, a sophisticated cybercriminal group that has shifted its focus from retail and insurance companies to airlines in what cybersecurity experts describe as a coordinated campaign against the sector.
    • “Hawaiian Airlines disclosed a cybersecurity incident Friday [June 27, 2025] affecting some of its IT systems while maintaining that flights continued operating safely and on schedule. The attack, first detected June 23, according to SEC filings, prompted the airline to engage federal authorities and cybersecurity experts for investigation and remediation efforts.
    • “Multiple incident responders have attributed the Hawaiian Airlines attack to Scattered Spider, also known as Muddled Libra or UNC3944. The assessment comes as cybersecurity firms Unit 42 and Mandiant issued warnings about the group’s apparent pivot to targeting aviation companies.
    • “Charles Carmakal, chief technology officer at Mandiant Consulting – Google Cloud, confirmed his company is “aware of multiple incidents in the airline and transportation sector which resemble the operations of UNC3944 or Scattered Spider.” The group has demonstrated a pattern of focusing intensively on single industries before moving to new sectors.”
  • Per Hacker News,
    • “Unknown threat actors have been distributing a trojanized version of SonicWall’s SSL VPN NetExtender application to steal credentials from unsuspecting users who may have installed it.
    • “NetExtender enables remote users to securely connect and run applications on the company network,” SonicWall researcher Sravan Ganachari said. “Users can upload and download files, access network drives, and use other resources as if they were on the local network.”
    • “The malicious payload delivered via the rogue VPN software has been code named SilentRoute by Microsoft, which detected the campaign along with the network security company.” * * *
    • “The development comes as G DATA detailed a threat activity cluster dubbed EvilConwi that involves bad actors abusing ConnectWise to embed malicious code using a technique called authenticode stuffing without invalidating the digital signature.
    • “The German cybersecurity company said it has observed a spike in attacks using this technique since March 2025. The infection chains primarily leverage phishing emails as an initial access vector or through bogus sites advertised as artificial intelligence (AI) tools on Facebook.”

From the ransomware front,

  • Bleeping Computer notes,
    • “Ahold Delhaize, one of the world’s largest food retail chains, is notifying over 2.2 million individuals that their personal, financial, and health information was stolen in a November ransomware attack that impacted its U.S. systems.
    • “The multinational retailer and wholesale company operates over 9,400 local stores across Europe, the United States, and Indonesia, employing more than 393,000 people and serving approximately 60 million customers each week in-store and online.” * * *
    • “In a Thursday filing with Maine’s Attorney General, the retail giant revealed that the attackers behind the November breach stole the data of 2,242,521 individuals after gaining access to the company’s internal U.S. business systems on November 6, 2024.”Mich
  • Michigan Health Watch adds,
  • Dark Reading reports,
    • “A newly discovered ransomware group dubbed “Dire Wolf” has already taken a bite out of 16 organizations globally since its emergence only last month, mainly across the technology and manufacturing sectors, researchers have found.
    • “The group uses a double extortion tactic with a monthlong turnaround time for paying ransom, and deploys custom encryptors tailored to specific victims, security firm Trustwave revealed in a blog post published June 24. Researchers from Trustwave SpiderLabs recently uncovered and observed a ransomware sample from the emerging threat group and gained insights on how it operates, they said.
    • “So far, the group’s victims have spanned 11 countries, with the US and Thailand reporting the highest numbers of attacks, followed by Taiwan. So far, five of the 16 victims listed on the group’s data leak site have data scheduled to be uploaded by the end of June, presumably because they didn’t pay the ransom, according to the post.”
  • Per Cybersecurity Dive,
    • “Only half of ransomware attacks on organizations this year have involved data encryption, once the attack’s defining feature, according to a Sophos report published on Tuesday [June 24, 2025].
    • “Both the average ransom demand and average ransom payment have dropped significantly over the past year (by 34% and 50%, respectively).
    • “Less than a third of respondents in the survey who paid a ransom said the amount matched the attackers’ initial demand, with 53% of victims paying less and 18% paying more.”

From the cybersecurity defenses front,

  • Cyberscoop reports,
    • “When a faulty software update from cybersecurity firm CrowdStrike last year caused possibly the largest IT outage in history, Microsoft ended up taking much of the blame.
    • “CrowdStrike’s Falcon endpoint detection and response was on millions of Windows devices worldwide, and like most antivirus products that need broad access to different systems to do their job, the software had direct access to the Windows kernel.
    • “When CrowdStrike’s update crashed, so did millions of Windows-powered systems and devices around the world. A series of security announcements by Microsoft on Thursday [June 26, 2025] are designed to reduce the possibility of future third-party outages and other security threats that can take an organization’s IT out of commission for extended durations.
    • “Among those changes: antivirus software like the kind installed by CrowdStrike and other third-party cybersecurity will no longer have direct access to the Windows kernel. The company will be previewing a new endpoint security platform to vendors next month that requires security updates to go through layers of testing and review before they ship to Windows devices and systems worldwide.”
  • Per Cybersecurity Dive,
    • “Cybersecurity insurance premiums declined 2.3% year over year to roughly $7.1 billion in 2024, according to a new report released on Monday [June 23, 2025] by credit rating agency AM Best.
    • “Meanwhile, cyber insurance providers’ loss ratio — the proportion of premiums they use to pay out claims — remained below 50%, indicating that the market remains profitable.
    • “AM Best offered several possible explanations for the slight premium decline.”
  • and
    • “Two reports — one that KPMG released on Thursday and one that Thales released last month — illustrate how generative AI is raising security concerns for business leaders.
    • “Business leaders surveyed by KPMG reported prioritizing security oversight in their generative AI budgeting decisions, with 67% saying they plan to spend money on cyber and data security protections for their AI models. Fifty-two percent cited risk and compliance as a budgetary priority.
    • “Those spending decisions reflect corporate executives’ growing worries about AI security. ***

David Ermer–Cybersecurity, Generative AI–

From the cybersecurity defenses and law enforcement front

  • Cyberscoop reports,
    • Congress should use renewal of an expiring [in 2027] terrorism insurance program to create a federal backstop for cybersecurity insurance, according to a report out Tuesday that tries to thread many difficult needles to bolster an industry that its author says isn’t developing fast enough.
    • In an ideal world, cybersecurity insurance can be a valuable tool to protect policyholders and push everyone into adopting better cyber practices, but it will need government intervention to reach its full potential amid an array of challenges, Nick Leiserson writes in a study for the Foundation for Defense of Democracies, a D.C.-based think tank. 
  • and
    • “As spring gives way to summer, a wave of cybercrime crackdowns has taken root, with law enforcement and private security companies directing a surge of takedowns, seizures, indictments and arrests.
    • “Prolific infostealers, malware loaders, counter antivirus and encrypting services, cybercrime marketplaces, ransomware infrastructure and DDoS-for-hire operations have all been seized, taken offline or severely disrupted by global coordinated campaigns over the past six weeks.
    • “It’s been really energizing to see the volume and velocity of these takedowns in such a short period of time,” Flashpoint CEO Josh Lefkowitz told CyberScoop. 
    • “I can’t think of such a flurry and rapid succession — and then magnified by complementary takedowns by Europol and international partners,” he added. “It’s been a great couple of weeks for the good guys, and I wouldn’t be surprised if there’s more around the horizon.”

From the cybersecurity vulnerabilities and breaches front,

  • Bleeping Computer informs us,
    • “News broke [on June 18] about “one of the largest data breaches in history,” sparking wide media coverage filled with warnings and fear-mongering. However, it appears to just be a compilation of previously leaked credentials stolen by infostealers, exposed in data breaches, and via credential stuffing attacks.
    • “To be clear, this is not a new data breach, or a breach at all, and the websites involved were not recently compromised to steal these credentials.
    • “Instead, these stolen credentials were likely circulating for some time, if not for years. It was then collected by a cybersecurity firm, researchers, or threat actors and repackaged into a database that was exposed on the Internet.
    • “Cybernews, which discovered the briefly exposed datasets of compiled credentials, stated it was stored in a format commonly associated with infostealer malware, though they did not share samples
    • “An infostealer is malware that attempts to steal credentials, cryptocurrency wallets, and other data from an infected device. Over the years, infostealers have become a massive problem, leading to breaches worldwide.”
  • Cybersecurity Dive reports,
    • “Major insurance provider Aflac Inc. said Friday [June 20] that it was the target of a cyberattack on June 12 that is linked to a major cybercrime spree focusing on the industry. 
    • “The company said it was able to contain the attack within hours and confirmed its systems remain operational. 
    • “We continue to serve our customers as we respond to this incident and can underwrite policies, review claims and otherwise service our customers as usual,” the company said in a Securities and Exchange Commission filing. 
    • “The incident is part of a larger crime wave targeting the insurance industry that researchers have linked to a collective known as Scattered Spider. The group recently conducted a weeks-long attack campaign against retailers in the U.S. and the U.K.
    • “Erie Insurance Group last week disclosed that it was the target of a cyberattack that began on June 7. The company said Tuesday that it has regained control over its systems and sees no further evidence of malicious activity.”
  • Cyberscoop adds,
    • Scattered Spider is an amorphous band of young English-speaking cybercriminals affiliated with the larger sprawling network known as The Com. Scattered Spider associates recently ran roughshod over U.K.- and U.S.-based retailers before pivoting, once again, to insurance companies.
    • The ring of cybercriminals historically focus on one sector at a time, resulting in a wave of extortion attacks on companies in the same industry, which often use similar systems and processes. 
    • Google previously warned that Scattered Spider shifted its attention to U.S. retailers after the group hit multiple retailers and grocery stores in the U.K. in April. The pattern of recent activities attributed to Scattered Spider has been consistent.
    • “We are now seeing incidents in the insurance industry,” John Hultquist, chief analyst at Google Threat Intelligence Group, told CyberScoop on Monday. “Given this actor’s history of focusing on a sector at a time, the insurance industry should be on high alert, especially for social engineering schemes which target their help desks and call centers.”
  • The Wall Street Journal points out,
    • “Hackers in recent months have disrupted retail sales in the U.K. and U.S. and stolen hundreds of millions of dollars from crypto holders by targeting the outsourced call centers that many American corporations use to save costs.
    • “The hacks are often meticulously researched and use a variety of techniques, but they have one thing in common: low-level workers who staff call centers and have access to the kind of sensitive information that criminals need to commit crimes.
    • “The focus on outside call centers has allowed attackers to trick workers to get around so-called two-factor account authentication techniques that send codes by text to mobile phones. Those methods are commonly used to protect millions of bank and credit-card accounts, as well as a host of other online portals.”
  • Security Week lets us know,
    • “Healthcare services firm Episource has been targeted in a cyberattack that resulted in a data breach impacting more than 5.4 million individuals.
    • “Episource provides medical coding and risk adjustment services to doctors, health plans, and other types of healthcare organizations. 
    • “The firm revealed in a data breach notice that it detected unauthorized access to its systems in early February. An investigation showed that “a cybercriminal” was able to view and copy data belonging to some Episource customers between January 27 and February 6, 2025. 
    • “We quickly took steps to stop the activity. We began investigating right away and hired a special team to help us. We also called law enforcement. We turned off our computer systems to help protect the customers we work with and their patients and members,” the company said, noting that it’s not aware of any misuse of the compromised data.”
  • Per Dark Reading,
    • Cybercriminals are using fake search engine listings to hijack the results for people looking for tech support from brands like Apple, Bank of America, Facebook, HP, Microsoft, Netflix, and PayPal.
    • This type of deceptive scam is common, taking advantage of users’ trust in big name brands, beginning with a sponsored search result on Google — but this time, there’s a twist.
    • According to Pieter Arntz and Jérôme Segura, researchers at Malwarebytes Labs, cybercriminals start by paying for a sponsored ad on Google pretending to be a major brand. This advertisement will then lead people to the fake website.
    • “However, in the cases we recently found, the visitor is taken to the legitimate site with a small difference,” the researchers wrote in a post this week. “Visitors are taken to the help/support section of the brand’s website, but instead of the genuine phone number, the hijackers display their scammy number instead.”
    • “So, while the browser address is legitimate and shows no cause for concern, the fraudsters overlay the actual website with misinformation, directing the user to seek help from a fraudulent source.”
  • Cybersecurity Dive tells us,
    • “Researchers are urging Veeam Backup & Replication users to make sure their systems are fully upgraded to the latest version after the company released a patch Tuesday to address a critical remote code execution flaw. 
    • “The vulnerability, tracked as CVE-2025-23121, allows an authenticated domain user to run code on a backup server. 
    • “Researchers at watchTowr and Code White GmbH previously disclosed that a patch to address a prior vulnerability, tracked as CVE-2025-23120, could be bypassed. That disclosure led to the development of the new patch.”

    • “Hackers are exploiting a critical vulnerability in Zyxel’s Internet Key Exchange packet decoder, GreyNoise researchers warned on Monday.
    • “The vulnerability, tracked as CVE-2023-28771, powered a sudden wave of exploitation attempts Monday, with researchers observing 244 unique IP addresses involved in the activity. 
    • “All of the addresses were located in the U.S. and registered to Verizon Business, but researchers caution that because the vulnerability was located over UDP (Port 500), the attackers may have been spoofing those addresses.
    • “Additional analysis suggests that the activity may be related to a variant of the Mirai botnet, researchers said. 
    • “Mirai-linked payloads suggest the activity may be aimed at enrolling devices into botnets for automated attacks like DDoS or scanning,” GreyNoise researchers told Cybersecurity Dive via email.”

From the ransomware front,

  • The Hacker News reports,
    • “An emerging ransomware strain has been discovered incorporating capabilities to encrypt files as well as permanently erase them, a development that has been described as a “rare dual-threat.”
    • “The ransomware features a ‘wipe mode,’ which permanently erases files, rendering recovery impossible even if the ransom is paid,” Trend Micro researchers Maristel Policarpio, Sarah Pearl Camiling, and Sophia Nilette Robles said in a report published last week.
    • “The ransomware-as-a-service (RaaS) operation in question is named Anubis, which became active in December 2024, claiming victims across healthcare, hospitality, and construction sectors in Australia, Canada, Peru, and the U.S. Analysis of early, trial samples of the ransomware suggests that the developers initially named it Sphinx, before tweaking the brand name in the final version.”
  • and
    • “The threat actors behind the Qilin ransomware-as-a-service (RaaS) scheme are now offering legal counsel for affiliates to put more pressure on victims to pay up, as the cybercrime group intensifies its activity and tries to fill the void left by its rivals.
    • “The new feature takes the form of a “Call Lawyer” feature on the affiliate panel, per Israeli cybersecurity company Cybereason.
    • “The development represents a newfound resurgence of the e-crime group as once-popular ransomware groups like LockBit, Black Cat, RansomHub, Everest, and BlackLock have suffered abrupt cessations, operational failures, and defacements. The group, also tracked as Gold Feather and Water Galura, has been active since October 2022.
    • “Data compiled from the dark web leak sites run by ransomware groups shows that Qilin led with 72 victims in April 2025. In May, it is estimated to be behind 55 attacks, putting it behind Safepay (72) and Luna Moth (67). It’s also the third most active group after Cl0p and Akira since the start of the year, claiming a total of 304 victims.”

From the cybersecurity defenses front,

    • “For organizations aiming to deploy generative AI at scale, focusing on the cybersecurity guardrails surrounding the technology can help ease adoption rather than hinder it, according to AWS CISO Amy Herzog. 
    • “Herzog, who took on the CISO role earlier this month, made the case for a closer enterprise focus on security during the company’s annual re:Inforce conference Tuesday. The strategy can pay off by speeding up adoption. 
    • “Security, when done right, can be a true enabler in adopting new technologies,” said Herzog. “What we’re noticing is customers with mature security practices and the ability to innovate while maintaining a high security bar, they’re adopting Gen AI faster.
    • “Companies in highly regulated environments, from finance to healthcare, have been able to rely on their existing security, privacy and data management guardrails to speed up AI adoption, Herzog said. 
    • “This enables them to reduce risks and pragmatically focus on scaling their use cases,” Herzog said.”
  • and
    • “Nearly one in 10 publicly accessible cloud-storage buckets contained sensitive data, with virtually all of that data considered confidential or restricted, according to a new report from Tenable based on scans conducted between October 2024 and March 2025.

  • Per Bleeping Computer,
    • “Microsoft has announced plans to periodically remove legacy drivers from the Windows Update catalog to mitigate security and compatibility risks.
    • “The rationale behind this initiative is to ensure that we have the optimal set of drivers on Windows Update that cater to a variety of hardware devices across the windows ecosystem, while making sure that Microsoft Windows security posture is not compromised,” Microsoft said.
    • “This initiative involves periodic cleanup of drivers from Windows Update, thereby resulting in some drivers not being offered to any systems in the ecosystem.
    • “As the company explained on Thursday, the first phase of this “cleaning up” procedure will involve drivers with newer replacements already published on Windows Update.”
  • CSO lets us know,
    • “Ransomware tabletop exercises confront participants with an attack scenario, offering them a way to test and improve their organization’s readiness and response capabilities.
    • “During this month’s Infosecurity Europe conference, CSO took part as a media advisor to a blue team, pitched against a red team of attackers in a ransomware tabletop simulation focused on the water industry. The “Operation 999” exercise was devised and run by cybersecurity vendor Semperis, a specialist in protecting Active Directory (AD) and hybrid identity environments.” * * *
    • “The “Operation 999” exercise offered a cybersecurity tabletop simulation designed to allow participants to exercise incident response strategies.

From the cybersecurity and law enforcement front,

  • Cyberscoop reports,
    • “A House panel approved a fiscal 2026 funding bill Monday [June 9, 2025] that would cut the Cybersecurity and Infrastructure Security Agency by $135 million from fiscal 2025, significantly less than the Trump administration’s proposed $495 million.
    • “The chairman of the House Appropriations Subcommittee on Homeland Security, Rep. Mark Amodei, said the annual Department of Homeland Security funding measure “responsibly trimmed” the CISA budget. But Illinois Rep. Lauren Underwood, the top Democrat on his panel, said the legislation “fails to address the catastrophic cybersecurity threats facing our critical infrastructure.”
    • “The subcommittee approved the bill by a vote of 8-4.
    • “CISA would get $2.7 billion under the measure, according to a committee fact sheet, or $134.8 million less than the prior year.

  • The National Institute of Standards and Technology (NIST) illustrates “19 Ways to Build Zero Trust Architectures.”
    • “The traditional approach to cybersecurity, built around the idea of solely securing a perimeter, has given way to the zero-trust approach of continuously evaluating and verifying requests for access.
    • “Zero trust architectures can help organizations protect far-flung digital resources from cyberattacks, but building and implementing the right architectures can be a complex undertaking.
    • “New NIST guidance offers 19 example zero trust architectures using off-the-shelf commercial technologies, giving organizations valuable starting points for building their own architectures.”
  • Cyberscoop points out,
    • “Federal authorities on Wednesday [June 11, 2025] announced the seizure of about 145 domains and cryptocurrency funds linked to BidenCash, a cybercrime marketplace for stolen credit cards, compromised credentials and other personal information. 
    • “BidenCash was used by more than 117,000 customers, resulting in the trafficking of more than 15 million credit card numbers and personally identifiable information, the Justice Department said. Administrators of the cybercrime platform, which charged a per-transaction fee, generated more than $17 million in illicit revenue since its formation in March 2022, authorities said.
    • “Domains associated with BidenCash now redirect to a server controlled by U.S. law enforcement and display seizure notices. The U.S. Attorney’s Office for the Eastern District of Virginia, which is leading the case, said it seized cryptocurrency funds the BidenCash marketplace used to receive illicit proceeds from its operations.
    • “Authorities did not disclose the value of those seized cryptocurrency funds or identify the physical location of the administrators and infrastructure used by BidenCash. The U.S. Attorney’s Office for the Eastern District of Virginia did not immediately respond to questions.” 
  • Cybersecurity Dive adds,
    • “An international law enforcement operation has dismantled the computer infrastructure powering multiple strains of information-stealer malware.
    • “As part of “Operation Secure,” authorities in 26 Asian countries “worked to locate servers, map physical networks and execute targeted takedowns,” Interpol said in a statement. Law enforcement agencies worked with cybersecurity firms Group-IB, Kaspersky and Trend Micro to prepare assessments of their targets and shared that information with “cyber teams across Asia,” according to Interpol, resulting in “in the takedown of 79 percent of identified suspicious IP addresses.”

    • “Roughly 80% of government agencies have software vulnerabilities that have gone unaddressed for at least a year, and roughly 55% of them have long-standing software flaws that place them at even greater risk, the report found.
    • “Veracode’s research shows that it takes government agencies an average of 315 days to resolve half of their software vulnerabilities, compared to the combined public- and private-sector average of 252 days.
    • “But companies and agencies alike are falling short of the necessary investments and procedures to address insecure software, according to Veracode.”
  • Dark Reading warns
    • “Secure Shell (SSH) keys are the backbone of secure remote access. They are everywhere, powering DevOps pipelines, enabling server management, and automating everything from deployments to patching. But despite their ubiquity, SSH keys often remain a blind spot in enterprise security. Why? Because unlike passwords, they don’t expire. They are easy to create, hard to track, and alarmingly simple to forget.
    • “In large enterprises, it is not uncommon to find hundreds of thousands or even millions of unmanaged SSH keys. Many of these grant access to sensitive systems but lack clear ownership or life-cycle oversight, turning what should be a secure authentication method into a major risk factor.
    • “If your organization cannot answer “Who can log in to what, using which key?” you are flying blind.”
  • Security Week notes,
    • “More than 40,000 security cameras worldwide are exposed to the internet, cybersecurity firm Bitsight warns.
    • “Operating over HTTP or RTSP (Real-Time Streaming Protocol), the cameras expose their live feed to anyone knowing their IP addresses, directly from the web browser, which makes them unintended tools for cyberattacks, espionage, extortion, and stalking, the company says.
    • “The HTTP-based cameras rely on standard web technologies for video transmission and control and are typically found in homes and small offices.
    • “Of the more than 40,000 cameras exposing their live feed, more than 14,000 are in the US, with Japan ranking second, at roughly 7,000 devices. Austria, Czechia, and South Korea have roughly 2,000 exposed cameras each, while Germany, Italy, and Russia have roughly 1,000 each.
    • “In the US, most of the exposed cameras are in California and Texas, followed by Georgia, New York, and Missouri. Massachusetts and Florida have high concentrations of exposed cameras as well.” * * *

Cybersecurity Saturday

David Ermer–Cybersecurity, Generative AI–

From the cybersecurity policy and law enforcement front,

  • Yesterday, the President issued a cybersecurity executive order. Here is a link to related fact sheet.
  • Federal News Network adds,
    • “President Donald Trump has signed a new cybersecurity executive order that continues many of the policies of his predecessors, while also marking out some key changes in the approach to software security, digital identity and more.
    • “The new executive order, “Sustaining Select Efforts to Strengthen the Nation’s Cybersecurity,” modifies many aspects of a cyber EO signed by President Joe Biden in January. It also makes changes to executive orders signed by President Barack Obama to focus federal cybersecurity law enforcement efforts on foreign nationals.
    • “But Trump’s new EO continues key aspects Biden directives, including an effort to strengthen the Cybersecurity and Infrastructure Security Agency’s role in defending civilian federal networks.” * * *
    • “The latest cybersecurity executive order also maintains federal efforts around post-quantum cryptography, Border Gateway Protocol, and advanced encryption.
    • “But it eliminates the January order’s directive for agencies to require federal software vendors to provide evidence of following secure development practices.
    • “Instead, Trump directs the National Institute of Standards and Technology to establish a new consortium with industry “that demonstrates the implementation of secure software development, security, and operations practices” based on NIST’s Secure Software Development Framework.”
  • Per Cybersecurity Dive,
    • “Trump’s elimination of Biden’s software security requirements for federal contractors represents a significant government reversal on cyber regulation. Following years of major cyberattacks linked to insecure software, the Biden administration sought to use federal procurement power to improve the software industry’s practices. That effort began with Biden’s 2021 cyber order and gained strength in 2024, and then Biden officials tried to add teeth to the initiative before leaving office in January. But as it eliminated that project on Friday, the Trump administration castigated Biden’s efforts as “imposing unproven and burdensome software accounting processes that prioritized compliance checklists over genuine security investments.”
    • “Trump’s order eliminates provisions from Biden’s directive that would have required federal contractors to submit “secure software development attestations,” along with technical data to back up those attestations. Also now eradicated are provisions that would have required the Cybersecurity and Infrastructure Security Agency to verify vendors’ attestations, required the Office of the National Cyber Director to publish the results of those reviews and encouraged ONCD to refer companies whose attestations fail a review to the Justice Department “for action as appropriate.”
  • Cyberscoop reports,
    • “Sean Cairncross laid out his vision to senators Thursday for the Office of the National Cyber Director if he is confirmed to lead it.
    • “A goal of mine is to make sure this office sits at the place that this committee and I believe Congress intended in the statute, and that is to lead cyber policy coordination across the federal government,” he told the Homeland Security and Governmental Affairs Committee at his confirmation hearing.
    • “In doing that, working with our interagency partners is vital,” he said. “We’ve been empowered to work with [the Office of Management and Budget] to ensure that budget alignment among the interagency aligns with administration policy, and I think those tools have to be leveraged, and relationships between us and the interagency — it’s making sure that it is monitored and enforced.”
  • Cybersecurity Dive adds,
    • “Two coalitions of cybersecurity companies, professional associations and experts have endorsed Sean Plankey and Sean Cairncross, President Donald Trump’s nominees to serve as director of the Cybersecurity and Infrastructure Security Agency and national cyber director, respectively.
    • “Plankey and Cairncross’s backers include executives at cybersecurity firms, former senior government officials from administrations of both parties and leaders of trade groups and think tanks.”
  • Per Bleeping Computer,
    • “The U.S. Department of State has announced a reward of up to $10 million for any information on government-sponsored hackers with ties to the RedLine infostealer malware operation and its suspected creator, Russian national Maxim Alexandrovich Rudometov.

    • “Federal authorities on Thursday [June 5, 2025] said they seized $7.74 million from North Korean nationals as they attempted to launder cryptocurrency obtained by IT workers who gained illegal employment and funneled the wages to the North Korean regime.
    • “The allegedly illegally obtained funds were linked to Sim Hyon Sop, a representative of North Korean Foreign Trade Bank, and Kim Sang Man, CEO of Chinyong, an outfit associated with North Korea’s Ministry of Defense, the Justice Department said. Both North Korean nationals were added to the Treasury Department’s Office of Foreign Assets Control’s list of sanctioned individuals in 2023.
    • “The cryptocurrency seizure marks another action in a series of long-running law enforcement efforts to identify and prevent North Korean operatives from gaining employment at companies, evading U.S. sanctions, and sending payroll back to the North Korean government.”
  • Per Security Week,
    • “German authorities have named Russian national Vitaly Nikolaevich Kovalev as the founder and leader of the TrickBot cybercrime gang.”
    • “Established in 2016, the TrickBot group is believed to have infected millions of computers worldwide, exfiltrating sensitive information such as credentials, banking and credit card details, and personal information, while also enabling the deployment of other malware, such as ransomware.
    • “Authorities targeted TrickBot’s infrastructure in takedown attempts in 2020 and 2024 and announced charges and sanctions against over a dozen group members in 2023, including Kovalev, believed at the time to be a senior figure within the cybercrime ring.”

Human Security’s Satori Threat Intelligence and Research team, alongside Google, Trend Micro, the Shadowserver Foundation, and others, were able to partially disrupt the “complex and expansive” BADBOX 2.0 operation, noting that it remains the largest botnet of infected connected TV (CTV) devices ever uncovered.
  • Per Cybersecurity Dive,
    • “A financially motivated hacker group has been targeting Salesforce instances for months in a campaign that uses voice phishing to engage in data theft and follow-on extortion attempts, according to Google Threat Intelligence Group. 
    • “The hackers, whom Google tracks as UNC6040, impersonated IT workers and tricked employees at often English-speaking branches of multinational companies into sharing sensitive credentials that were then used to access the organizations’ Salesforce data, Google said in a blog post published Wednesday.
    • “As part of the social engineering campaign, the hackers tricked workers at these companies into visiting the Salesforce-connected app setup page, at which point the attackers used an unauthorized, malicious version of the Salesforce Data Loader app to access and steal sensitive information from the customers’ Salesforce environments. 
    • “Beyond the immediate data thefts, the hackers were able to move laterally within target networks, accessing victims’ other cloud services and moving into internal corporate networks.”

From the ransomware front,

  • The American Hospital Association warns,
    • “The FBI, Cybersecurity and Infrastructure Security Agency and Australian Cyber Security Centre June 4 released an advisory on updated actions and tactics used by the Play ransomware group. The group, active since 2022, has impacted a wide range of businesses and critical infrastructure in North America, South America and Europe. As of May, the FBI was aware of about 900 victims allegedly exploited by the group’s efforts.
    • “The threat actors are presumed to be a closed group, designed to “guarantee the secrecy of deals,” according to a statement on the group’s data leak website. They employ a double-extortion model that encrypts systems after exfiltrating data. Their ransom notes do not include an initial ransom demand or payment instructions. Instead, victims are instructed to contact the threat actors via email.
    • “Play ransomware was among the most active cyberthreat groups in 2024,” said Scott Gee, AHA deputy national advisor for cybersecurity and risk. “This report highlights their evolving tactics, and health care cybersecurity teams should be aware of the changes.  As threat actors shift tactics, it is critical that network defenders keep pace. The double-layered extortion model and encryption of systems, as well as theft of data, pose a serious potential risk to hospitals and the delivery of health care.”
  • Cybersecurity Dive adds,
    • “Since mid-January, multiple ransomware groups, including initial access brokers affiliated with Play, have targeted vulnerabilities in a remote support tool called SimpleHelp. Researchers disclosed those flaws in January.  
    • “The new advisory updates the government’s original December 2023 warning about the Play ransomware group, which is also known as PlayCrypt. The hackers have previously been blamed for attacks targeting ConnectWise ScreenConnect and Rackspace. 
    • “The recent attacks exploiting SimpleHelp involve three flaws discovered by security firm Horizon3.ai.”
  • Bleeping Computer lets us know,
    • “Healthcare giant Kettering Health, which manages 14 medical centers in Ohio, confirmed that the Interlock ransomware group breached its network and stole data in a May cyberattack.
    • “Kettering Health operates over 120 outpatient facilities and employs over 15,000 people, including over 1,800 physicians.
    • “The healthcare network noted in a Thursday statement that its network devices have been secured, and its team is now working on re-establishing communication channels with patients disrupted by the outage triggered by last month’s ransomware attack.”
  • Security Week adds,
    • “American media company Lee Enterprises revealed this week that the disruptive cyberattack it dealt with earlier this year resulted in a data breach impacting nearly 40,000 individuals.
    • “Lee Enterprises owns 350 weekly and specialty publications across 25 states, and dozens of them suffered disruptions in February as a result of a ransomware attack that involved the encryption of critical applications and the theft of files.
    • “The company informed the Maine Attorney General’s Office this week that it recently completed its investigation into the incident and determined that personal information was compromised.
    • “According to Lee Enterprises, the attackers may have obtained the information of 39,779 people, including their names and Social Security numbers.
    • “Affected individuals are being offered 12 months of free credit monitoring and identity protection services.”
  • Honeywell lets us know,
    • “In a growing wave of sophisticated cyber threats against the industrial sector, ransomware attacks jumped by 46% from Q4 2024 to Q1 2025, according to Honeywell’s new 2025 Cybersecurity Threat Report. The research also found that both malware and ransomware increased significantly in this period and included a 3,000% spike in the use of one trojan designed to steal credentials from industrial operators.”

    • “Palo Alto Networks and Google and its Mandiant unit have also agreed to join the collaborative effort on streamlining threat group taxonomy.
    • “For years, the companies’ different naming conventions for various criminal and state-linked threat groups have created unnecessary confusion and delays in the sharing of threat intelligence.
    • “Microsoft and CrowdStrike released an initial version of their threat actor matrix on Monday, listing the groups they track and each one’s corresponding aliases from other researchers.
    • “Palo Alto Networks and Google and its Mandiant unit are joining the collaborative effort on streamlining threat group taxonomy.”
  • The Wall Street Journal reports,
    • “CrowdStrike swung to a loss in the fiscal first quarter and posted a lower-than-expected outlook, as the costs of its outage last summer continue to weigh on results.
    • “The cybersecurity company said Tuesday its revenue is still being hurt by an incentive program it launched last year to try to retain customers after a widespread software outage in July.
    • “CrowdStrike had implemented a customer-commitment program, which let customers try some products for free, and was weighing on its subscription revenue. The program wrapped up at the end of fiscal-year 2025, but its effects are lingering.”
  • Dark Reading tells us,
    • “F5 this week announced the acquisition of Fletch, a San Francisco-based startup with agent-based artificial intelligence (AI) technology that analyzes massive amounts of threat intelligence data and remediates the most severe vulnerabilities in real time.
    • “Terms of the deal were not disclosed, but most of Fletch’s 15 employees have joined F5, which was seeking the technology and expertise to bring agentic AI capabilities to the recently introduced F5 Application Delivery and Security Platform (ADSP).”
  • Help Net Security points out,
    • “Cybersecurity leaders and consultants identified AI-driven automation and cost optimization as top organizational priorities, according to Wipro. 
    • “30% of respondents are investing in AI automation to enhance their cybersecurity operations. AI-driven automation can help in detecting and responding to threatsmore quickly and accurately, thereby reducing the need for extensive manual intervention. 
    • ‘26% of respondents are focusing on tools rationalization. This approach involves evaluating and consolidating duplicate security tools across platforms to eliminate redundancies and improve efficiency while reducing costs. 
    • “Another significant area is security and risk management process optimization, with 23% of organizations targeting this for cost savings. Streamlining these processes can lead to more effective risk management and better allocation of resources. Apart from these priorities, 20% are focusing on simplifying operating models to achieve better visibility and faster response across reduced attack surfaces.”

Cybersecurity Saturday

David Ermer–Cybersecurity, Generative AI–

Cybersecurity policy and law enforcement,

  • Helpnet Security tells us,
    • “NIST has introduced a new way to estimate which software vulnerabilities have likely been exploited, and it’s calling on the cybersecurity community to help improve and validate the method.
    • “The new metric, “Likely Exploited Vulnerabilities” (LEV), aims to close a key gap in vulnerability management: identifying which of the thousands of reported flaws each year are actually being used in real-world attacks.
    • “Organizations typically rely on two main tools for this: the Exploit Prediction Scoring System (EPSS), which estimates the chance of future exploitation, and Known Exploited Vulnerability (KEV) lists like the one maintained by CISA. But both have limits. EPSS is predictive and doesn’t account for past exploitation, while KEV lists are confirmed cases but often incomplete.
    • “LEV aims to bridge that gap by calculating the probability that a vulnerability has been exploited in the past, based on historical EPSS data. It’s a statistical estimate, not a confirmation, which is why the whitepaper emphasizes that LEV is meant to augment, not replace, existing methods.” * * *
    • The researchers outline four key ways LEV could be used:
      • 1. Estimate how many vulnerabilities have been exploited.
      • 2. Check how complete KEV lists are.
      • 3. Identify high-risk vulnerabilities missing from those lists.
      • 4. Fix blind spots in EPSS, which sometimes underestimates risk for already-exploited bugs.
  • Next Thursday, the Senate Homeland Security and Governmental Affairs Committee will hold a confirmation hearing for the following Department of Homeland Security nominees.
    • Sean Cairncross, of Minnesota, to be National Cyber Director, Robert Law, of the District of Columbia, to be Under Secretary for Strategy, Policy, and Plans, James Percival, of Florida, to be General Counsel, Sean Plankey, of Pennsylvania, to be Director of the Cybersecurity and Infrastructure Security Agency, and Kevin Rhodes, of Florida, to be Administrator for Federal Procurement Policy.
  • Federal News Network reports yesterday,
    • “The Trump administration is proposing to cut more than 1,000 positions at the Cybersecurity and Infrastructure Security Agency.
    • “Under the 2026 budget request, CISA would go from approximately 3,732 funded positions today to 2,649 positions next year. The staff reductions are detailed in CISA’s fiscal 2026 budget justification, posted today. They present the most detailed view yet of the Trump administration’s proposal to cut CISA’s budget by nearly $500 million.
    • “The proposed cuts still have to be approved by Congress as part of the 2026 appropriations process. But they come as hundreds of CISA employees have already left under the Trump administration. Meanwhile, more staff could depart through deferred resignations or early retirements offered to DHS staff in April.
    • “The proposed cuts are spread across CISA’s various divisions. CISA’s cybersecurity division would go from 1,267 positions to 1,063 jobs. CISA’s infrastructure security division would go from about 343 positions to 325 jobs.”
  • Dark Reading informs us,
    • “The Cybersecurity and Infrastructure Security Agency (CISA) and Australian Cyber Security Centre (ACSC) released new guidance this week on procuring, implementing, and maintaining security information and event management (SIEM) and security orchestration, automation, and response (SOAR) platforms.
    • “SIEM and SOAR help organizations collect and analyze data from firewalls, endpoints, and applications to better detect and respond to cybersecurity incidents. However, many organizations encounter significant implementation and deployment challenges, including significant costs and ongoing maintenance requirements. The guidance noted these are not “set it and forget it” tools.
    • “These platforms are becoming more essential as organizations store and manage an influx of data that is highly attractive to attackers, particularly personally identifiable information and personal health information. Additionally, increasing infrastructure complexity is creating gaps in visibility and making threat detection more difficult. There are more endpoints to secure, more applications, more third-party vendors, and more remote workers for attackers to exploit.”  
  • Per HHS Office for Civil Rights news releases,
  • and
    • “Today [May 30, 2025], the U.S. Department of Health and Human Services (“HHS”), Office for Civil Rights (“OCR”) announced a settlement with Comstar, LLC (“Comstar”), a Massachusetts company that provides billing, collection, and related services to non-profit and municipal emergency ambulance services, concerning potential violations of the Health Insurance Portability and Accountability Act of 1996 (HIPAA) Security Rule. The settlement resolves an OCR investigation concerning a ransomware breach that affected 585,621 individuals.”
    • “Under the terms of the settlement, Comstar agreed to implement a corrective action plan that OCR will monitor for two years, and paid OCR $75,000.”

  • Cybersecurity Dive points out,
    • “U.S. authorities on Thursday [May 28, 2025] charged 16 defendants in a massive global operation to disrupt the Russia-based cybercrime group behind the DanaBot malware. 
    • “DanaBot infected more than 300,000 computers around the world, facilitating fraud and ransomware and resulting in more than $50 million in damage, according to federal prosecutors. The U.S. coordinated with multiple foreign governments and private cybersecurity firms to dismantle the botnet operators’ infrastructure.
    • “The Department of Justice charged Aleksandr Stepanov, 39, a.k.a. “JimmBee,” with conspiracy, conspiracy to commit wire and bank fraud and additional charges. Artem Aleksandrovich Kalinkin, 34, a.k.a. “Onix,” was charged with conspiracy to gain unauthorized access to a computer to gain information and to defraud, among additional charges.

From the cybersecurity vulnerabilities and breaches front,

  • Cybersecurity Dive informs us,
    • “A previously unknown team of Russian government-backed hackers is targeting critical infrastructure organizations in multiple sectors to collect intelligence for Moscow, Microsoft and the Dutch government said in separate reports published Tuesday.
    • “The group, which Microsoft calls Void Blizzard and the Dutch intelligence services call Laundry Bear, has been using stolen credentials and automated bulk-email collection from cloud services to scoop up data on NATO member states and Ukraine.
    • “Void Blizzard’s cyberespionage operations tend to be highly targeted at specific organizations of interest to the Russian government, including in government, defense, transportation, media, non-governmental organizations (NGOs), and healthcare sectors primarily in Europe and North America,” Microsoft said in a blog post.”
  • and
    • “A “highly targeted” spearphishing campaign is attempting to ensnare financial executives at banks, investment firms, energy utilities and insurance companies around the world, Trellix said in a report published Wednesday.
    • “The malicious emails are rigged with installers that allow the hackers to remotely access victim computers.
    • “With this amount of access to legitimate accounts, attackers could steal files or initiate fraudulent money transfers, potentially without raising red flags.”
  • and
    • “ConnectWise is investigating suspicious activity — likely associated with a nation-state actor — affecting a limited number of customers that use ScreenConnect. 
    • “In a post on its website, ConnectWise said it has notified all affected customers, alerted law enforcement to the attack and retained Mandiant to help with its investigation. 
    • “A company spokesperson added that ConnectWise issued a patch for ScreenConnect, implemented enhanced monitoring and hardening measures across its environment.” 
  • and
    • “More than 9,000 ASUS routers have been compromised in a months-long hacking campaign that researchers from GreyNoise warn may be a prelude to the creation of a botnet.
    • “Hackers are breaching routers through brute-force login attempts and authentication bypasses that rely on a command injection vulnerability, tracked as CVE-2023-39780, to execute system commands, GreyNoise researchers said in a blog post on Wednesday.
    • “GreyNoise first detected suspicious activity in March, when it flagged three suspicious HTTP POST requests made to ASUS routers, according to Matthew Remacle, senior researcher at GreyNoise.
    • “ASUS released a patch for the vulnerability in a recent firmware update, but the initial bypass attempts have not received CVEs, according to GreyNoise. In addition, researchers say, if a router was compromised before the firmware was updated, a backdoor will still remain on the devices unless secure shell protocol access is explicitly disabled.” 
  • Per Cyberscoop,
    • “As the internet fills up with clips from AI-video generators, hacking groups are seeding the online landscape with malware-laced programs and fake websites hoping to cash in on the trend.
    • “Tracked by researchers at Mandiant and Google Cloud, the campaign is being carried out by a group identified as “UNC6032.” Since mid-2024, they have spread thousands of advertisements, fake websites and social media posts promising victims access to popular prompt-to-video AI generation tools like Luma AI, Canva Dream Lab and Kling AI.
    • “Those promises lead to phishing pages and malware, with the group deploying infostealers and backdoors on victim devices. Compromised parties saw their login credentials, cookies, credit card data and in some cases Facebook information stolen, and the scheme appears to be impacting a wide range of industries and geographic areas.”
  • CISA did not add any known exploited vulnerabilities to its catalog this week.

From the ransomware front,

  • Dark Reading tells us,
    • “Extortionist-cum-information broker “Everest Group” has pulled off a swath of attacks against large organizations in the Middle East, Africa, Europe, and North America, and is now extorting victims over records stolen from their human resources departments.
    • “This May, the long-overlooked threat actor advertised nine new cyberattacks. Victims ranged from healthcare organizations to construction and facilities management companies. But its biggest win came against Coca-Cola, from which it stole records associated with hundreds of employees, including their personally identifying information (PII) like names and addresses, salary records, and scans of passports and visas.
    • “In each of these leaks, researchers from VenariX found files relating to SAP SuccessFactors, SAP’s cloud-based HR management platform. The researchers believe the attacks to be legitimate and estimate that initial access in each case likely occurred through a third-party SAP service provider called “INK IT Solutions.”
  • The Hacker News notes,
    • “The threat actors behind the DragonForce ransomware gained access to an unnamed Managed Service Provider’s (MSP) SimpleHelp remote monitoring and management (RMM) tool and then leveraged it to exfiltrate data and drop the locker on multiple endpoints.
    • “It’s believed that the attackers exploited a trio of security flaws in SimpleHelp (CVE-2024-57727, CVE-2024-57728, and CVE-2024-57726) that were disclosed in January 2025 to access the MSP’s SimpleHelp deployment, according to an analysis from Sophos.
    • “The cybersecurity company said it was alerted to the incident following a suspicious installation of a SimpleHelp installer file, pushed via a legitimate SimpleHelp RMM instance that’s hosted and operated by the MSP for their customers.”
    • The threat actors have also been found to leverage their access through the MSP’s RMM instance to collect information from different customer environments about device names and configuration, users, and network connections.
  • Fortra tells us what we need to know about Interlock ransomware.
  • Per Bleeping Computer,
    • “Threat actors linked to lesser-known ransomware and malware projects now use AI tools as lures to infect unsuspecting victims with malicious payloads.
    • “This development follows a trend that has been growing since last year, starting with advanced threat actors using deepfake content generators to infect victims with malware.
    • “These lures have become widely adopted by info-stealer malware operators and ransomware operations attempting to breach corporate networks.
    • “Cisco Talos researchers have discovered that the same technique is now followed by smaller ransomware teams known as CyberLock, Lucky_Gh0$t, and a new malware named Numero.
    • “The malicious payloads are promoted via SEO poisoning and malvertising to rank them high in search engine results for specific terms.”
  • Per CFO Dive,
    • “About one in four companies targeted in a ransomware incident in the last year did not get all their data back after paying the attacker, cybersecurity firm Delinea said in a report released Wednesday.
    • “Delinea also found that most ransomware today includes data-theft extortion, with 85% of victims saying they were threatened with having their data published or sold.
    • “Paying the ransom doesn’t always bring the desired results,” Delinea said in the report.”

From the cybersecurity business and defenses front,

  • Dark Reading notes,

    • “Founded in 2023, Apex helps organizations discover ungoverned AI. Co-founders Matan Derman (CEO) and Tomer Avni (chief product officer) developed a platform designed to surface all AI activities, including shadow apps, AI-generated code, and fake identities. The boutique company of roughly 20 employees competes with Prompt Security, Lasso Security, and Aim Security.”
  • Per Cyberscoop,
    • “Zscaler announced Tuesday its intention to acquire Red Canary, a company known for Managed Detection and Response (MDR) services, to boost its ability to integrate artificial intelligence, automation and human expertise into its security offerings. 
    • “The acquisition is positioned around the convergence of Zscaler’s data-driven, AI-centric cloud security and Red Canary’s decade of operational expertise in MDR. Zscaler’s executive leadership emphasizes the blending of large-scale data intelligence and automated, agentic Security Operations Centers (SOCs) with the capabilities of ThreatLabz, its security research division.
    • “The proposed acquisition of Red Canary is a natural expansion of our capabilities into managed detection and response and threat intelligence to accelerate our vision of AI-powered SOC of the future,” Jay Chaudhry, CEO and founder of Zscaler, said in a press release. “By integrating Red Canary with Zscaler, we will deliver to our customers the power of a fully integrated Zero Trust platform and AI-powered security operations.”
  • Dark Reading lets us know,
    • “Chief information security officers (CISOs) are being paid better than ever, more likely to be an executive — or report directly to an executive — and have expanding responsibilities. Yet tight security budgets continue to be a major challenge.
    • “Overall, the top cybersecurity professional is doing well at large companies and has proven their value but continually has to work to link security to business opportunities rather than costs, according to two surveys published this week.
    • “The average CISO at large US companies — those with revenue of $1 billion or more — has a current compensation of $532,000, including base salary, bonuses, and equity benefits, according to survey data published by cybersecurity consultancy IANS Research on May 29. Increasing responsibilities come with the high salaries, with CISOs now often charged with assessing business risk, product security, and digital strategy.

  • Dark Reading points out “3 Severe Bugs Patched in Versa’s Concerto Orchestrator. Three zero-days could have allowed an attacker to completely compromise the Concerto application and the host system running it.”
  • Per SC Media,
    • “Stolen credentials were the root cause of more than 30% of data breaches last year, according to Verizon’s 2025 Data Breach Investigations Report. Attackers compromised more than 23 million unmanaged and user-controlled devices—including personal laptops and home systems used in remote work settings—to extract login information, often using session cookies to bypass multi-factor authentication and other access controls.
    • “Credentials don’t just manifest—you’re either phishing them, brute forcing them, or stealing them via malware,” said Philippe Langlois, lead data scientist at Verizon and co-author of the 2025 DBIR, speaking at last month’s RSAC 2025.
    • “Those numbers aren’t outliers—they’re symptoms of a deeper failure in enterprise cybersecurity. Identity systems, Langlois noted at RSAC 2025, are now routinely exploited as entry points with attackers relying less on technical exploits—like finding and exploiting software vulnerabilities—and more on credential-based access, where they simply log in using stolen usernames, passwords, or hijacked sessions.”

From the ransomware front,

  • Cybersecurity Dive lets us know,
    • “Kettering Health is facing a cyberattack that’s impacting patient care, the Ohio-based health system said on Tuesday [May 20].
    • “The provider was hit by a system-wide technology outage Tuesday morning due to unauthorized access to its network, Kettering said in a press release. 
    • “Elective inpatient and outpatient procedures at the health system’s facilities were canceled Tuesday. Kettering’s call center was also knocked offline and might have been occasionally inaccessible, the provider added.”
  • Security Week informs us,
    • “In a data breach notice published on its website, Marlboro-Chesterfield Pathology said it discovered unauthorized activity on some internal IT systems on January 16, 2025. An investigation revealed that the hackers had stolen some files.
    • “The compromised data includes personal information such as name, address, date of birth, medical treatment information, and health insurance information. The stolen information varies by individual. 
    • “MCP informed the US Department of Health and Human Services (HHS) this week that the incident impacted 235,911 individuals.”
  • Per Bleeping Computer,
    • “The FBI warned that an extortion gang known as the Silent Ransom Group has been targeting U.S. law firms over the last two years in callback phishing and social engineering attacks.
    • “Also known as Luna Moth, Chatty Spider, and UNC3753, this threat group has been active since 2022and was also behind BazarCall campaigns that provided initial access to corporate networks for Ryuk and Conti ransomware attacks.
    • “In March 2022, following Conti’s shutdown, the threat actors separated from the cybercrime syndicate and formed their own operation called Silent Ransom Group (SRG).
    • “In recent attacks, SRG impersonates the targets’ IT support in email, fake sites, and phone calls using social engineering tactics to gain access to the targets’ networks.
    • “This extortion group doesn’t encrypt the victims’ systems and is known for demanding ransoms not to leak sensitive information stolen from compromised devices online.”
  • Per Dark Reading,
    • “Yet another threat group has embraced the trend of combining email bombing with vishing to gain initial access to systems and deploy ransomware.
    • “This time the adversary employing the technique, first documented as a tactic of Black Basta ransomware group, is the recently emerged 3AM ransomware group, researchers at Sophos revealed in a recent blog post. Sophos spotted an attack in the first quarter this year by 3AM affiliates, which followed the familiar playbook and successfully stole data from the targeted system but did not complete the ransomware attack.”
  • Per Fortra’s Tripline,
    • “Health-ISAC recently released their 2025 Health Sector Cyber Threat Landscape Report, a comprehensive outline of the malicious activity aimed at healthcare in the previous year. Not surprisingly, ransomware was cited by security professionals in the industry as the number one threat of 2024 and the top area of concern coming into 2025 (followed by third-party breaches, supply chain attacks, and zero-day exploits). Some things never change.

David Ermer–Cybersecurity, Generative AI–

From the cybersecurity policy and law enforcement front,

  • Cybersecurity Dive reports,
    • Congress moved one step closer to reauthorizing a key cyber threat information-sharing law on Thursday during a hearing that highlighted both the act’s value and potential shortcomings.
    • The House Homeland Security Committee’s cyber subcommittee held the hearing [on May 15] to evaluate the private sector’s satisfaction with the 2015 Cybersecurity Information Sharing Act, which expires on Sept. 30. Witnesses from the tech industry praised the law for encouraging companies to share cyber threat indicators with each other and with federal agencies, but they also offered lawmakers suggestions for how to improve the program.”
  • Defensescoop tells us,
    • “The Department of Defense has expanded its number of cyber teams by 12, with two more slated to come online in the next few years, according to a spokesperson.
    • “The cyber mission force began building in 2012, and the initial 133 teams reached full operational capability in 2018. In DOD’s fiscal 2022 budget request, U.S. Cyber Command proposed and was eventually approved for a phased approach to add 14 additional cyber mission force teams beyond the original 133. That request and authorization in 2021 was the first substantial effort to grow that force since it was designed almost a decade ago, long before modern and advanced threats had surfaced.
    • “In 2021, the Secretary of Defense directed the creation of 14 New cyber teams by September 2028. Of the 14 teams, 12 have been established. These teams are spread across Army, Air Force, and Navy Commands,” a Cybercom spokesperson said.
    • “They declined to offer specifics regarding how many additional teams each service received or what types of teams those additional builds provided to each service — such as offensive, defensive or support teams — citing operational security.”
  • Per a May 15 HHS press release,
    • “Today, the U.S. Department of Health and Human Services (HHS), Office for Civil Rights (OCR) announced a settlement with Vision Upright MRI, a small California health care provider that conducts magnetic resonance imaging and related services, concerning potential violations of the Health Insurance Portability and Accountability Act of 1996 (HIPAA) Breach Notification and Security Rules. The settlement resolves an OCR investigation concerning the breach of an unsecured server containing the medical images of 21,778 individuals.” * * *
    • “Under the terms of the resolution agreement, Vision Upright MRI agreed to implement a corrective action plan that will be monitored by OCR for two years and paid $5,000 to OCR.” 
    • “The resolution agreement and corrective action plan may be found at: https://www.hhs.gov/hipaa/for-professionals/compliance-enforcement/agreements/hhs-ocr-hipaa-racap-vum/index.html“
  • Cyberscoop informs us,
    • “Federal authorities seized two domains and indicted four foreign individuals for alleged involvement in a long-running botnet service that infected older wireless internet routers, the Justice Department said Friday. 
    • “The malware created for the botnet allowed infected routers to be reconfigured, which granted unauthorized access to third parties and made the routers available for sale as proxy servers on Anyproxy.net and 5socks.net, according to law enforcement officials. Both domains, which were managed by a company headquartered in Virginia and hosted on servers worldwide, now render seizure notices under an effort the DOJ and FBI dubbed “Operation Moonlander.”
    • “The 5socks.net website claimed to be in operation for over 20 years and had more than 7,000 proxies for sale worldwide for a monthly subscription of $9.95 to $110 per month, according to prosecutors. The botnet’s overseas operations were also seized and disabled by law enforcement agencies in the Netherlands and Thailand.
    • “Authorities also indicted the botnet’s alleged administrators and charged them with conspiracy and damage to protected computers, for conspiring with others to maintain, operate and profit from the bot.”
  • and
    • Liridon Masurica, the alleged lead administrator of cybercrime marketplace BlackDB.cc, was extradited to the United States on Friday and faces charges that carry a maximum penalty of 55 years in federal prison, the Justice Department said Tuesday. 
    • Masurica, 33, who is also known as “@blackdb,” was arrested by authorities in Kosovo on Dec. 12. He made his initial appearance in federal court in Tampa, Fla., on Tuesday and was ordered detained pending a trial. 
    • Federal prosecutors charged Masurica with one count of conspiracy to commit access device fraud and five counts of fraudulent use of 15 or more unauthorized access devices.
    • Masurica, of Gjilan, Kosovo, is accused of running BlackDB.cc since 2018. The cybercriminal marketplace offered to sell compromised account and server credentials, credit card information and other personally identifiable information of individuals mostly located in the United States, the DOJ said.

From the cybersecurity breaches and vulnerabilities front,

  • Cyberscoop reports,
    • “Hundreds of victims are surfacing across the world from zero-day cyberattacks on Europe’s biggest software manufacturer and company, in a campaign that one leading cyber expert is comparing to the vast Chinese government-linked Salt Typhoon and Volt Typhoon breaches of critical infrastructure.
    • “The zero-days — vulnerabilities previously unknown to researchers or companies, but that malicious hackers have discovered — got patches this month and last month, but there are signs it could be getting worse before it gets better, according to Dave DeWalt, CEO of NightDragon, a venture capital and advisory firm. Ransomware gangs are now reported to be exploiting it, beyond the original Chinese government-connected attackers.
    • “The net of it is this is like the Typhoon size, so much like we saw [with] Volt Typhoonand then Salt Typhoon,” DeWalt told CyberScoop. “Once these exploits get into the wild, it’s a race to see who can get more access to it. So initially it looks like three Chinese actors all used it, and now we’re going to see more.”
    • “A number of companies have been tracking the vulnerability and its consequences, including one, Onapsis, that DeWalt’s company invests in, along with EclecticIQ, ReliaQuest and Google’s Mandiant.”
  • and
    • “Over the past few years, cybersecurity experts have increasingly said that nation-state operatives and cybercriminals often blur the boundaries between geopolitical and financial motivations. A new report released Wednesday shows how North Korea has flipped that idea on its head. 
    • “North Korea has silently forged a global cyber operation that experts now liken to a mafia syndicate, with tactics and organization far removed from other nation-state actors, according to a comprehensive new report released by DTEX Systems.
    • “The study — based on years of investigations, technical analysis, and work with other open-source intelligence analysts — pulls back the curtain on a highly adaptive regime that has built its cyber capabilities on a survivalist, profit-driven approach. It reveals a hierarchy blending criminality, espionage, and front-line IT work, coordinated by an authoritarian government that rewards loyalty and secrecy while punishing failure.” * * *
    • “You can read the full report on DTEX’s website.”
  • Cybersecurity Dive relates.
    • “The FBI is warning about a threat campaign in which malicious actors are impersonating senior U.S. officials using malicious text messages and AI-generated voice messages.
    • “The messages have been sent to current and former federal and state officials and others who may be contacts of those individuals, the bureau said in an alert released Thursday.
    • “The messages are designed to establish a rapport with individuals who might then turn over access to a personal account, according to the alert. These social engineering techniques could be used to reach additional contacts and gain access to additional information or funds.”
  • Bleeping Computer lets us know,
    • “A new tool called ‘Defendnot’ can disable Microsoft Defender on Windows devices by registering a fake antivirus product, even when no real AV is installed.
    • “The trick utilizes an undocumented Windows Security Center (WSC) API that antivirus software uses to tell Windows it is installed and is now managing the real-time protection for the device.
    • “When an antivirus program is registered, Windows automatically disables Microsoft Defender to avoid conflicts from running multiple security applications on the same device.
    • “The Defendnot tool, created by researcher es3n1n, abuses this API by registering a fake antivirus product that meets all of Windows’ validation checks. * * *
    • “While Defendnot is considered a research project, the tool demonstrates how trusted system features can be manipulated to turn off security features.
    • “Microsoft Defender is currently detecting and quarantining Defendnot as a ‘Win32/Sabsik.FL.!ml; detection.”

    • “Among the numerous fixes, iOS 18.5 and iPadOS 18.5 introduce the first security update for Apple’s in-house C1 modem, featured in the newly released iPhone 16e. The patch addresses a baseband vulnerability (CVE-2025-31214) that, according to the company, could have allowed an attacker “in a privileged network position” to intercept network traffic. While the specific details remain undisclosed, the risk highlights concerns about how devices communicate on the hardware level, since baseband processors control things like data transmission, call processing, and other network functions.”
  • PC World reports
    • “Malware is a thing you just have to be aware of. But it’s pretty rare that it can actually damage your computer in a permanent sense — wipe the drive if you’re okay with losing local data, and you can generally get up and running in a day or two. But what if the microcode running on your CPU’s tiny integrated memory becomes infected? One security researcher says he’s done it.
    • “Christiaan Beek of Rapid7 says he has created a proof-of-concept ransomware that can hide inside a CPU’s microcode, building on previous work that emerged when Google required AMD processors to always return “4” when asked for a random number. He claims that modifying UEFI firmware can install an unsigned update to the processor, slipping past any kind of conventional antivirus or OS-based security.” * * *
    • “CPU-level ransomware has not been seen “in the wild,” and it seems likely that when and if it emerges, it’ll be a state-level actor that exploits it first. That means your typical user probably won’t be targeted, at least immediately. Still, maybe keep a remote backup of your important files, just in case.”

From the ransomware front,

  • Per a news release,
    • “Black Kite, the leader in third-party cyber risk intelligence, today announced its newest report, 2025 Ransomware Report: How Ransomware Wars Threaten Third-Party Cyber Ecosystems, which provides a deep analysis into evolving ransomware trends and threats. The report found that threats have escalated with more actors, less predictability, and deeper entanglement in supply chains, underscoring an urgent need for organizations to implement intelligence-driven defenses and proactive vendor monitoring.”
  • Beckers Hospital Review tells us,
    • “From October 2009 to October 2024, ransomware and hacking have increasingly driven healthcare data breaches, a May 14 study published in JAMA Network Open found. 
    • “The study examined ransomware attacks and other hacking incidents across all healthcare organizations covered by HIPAA from October 2009 through October 2024. It analyzed breaches affecting 500 or more patient records that were reported to the U.S. Department of Health and Human Services (HHS) Office for Civil Rights.”
  • Cybersecurity Dive reports,
    • “A cybercrime gang believed to be responsible for three attacks in the U.K. in recent weeks has turned its attention toward the U.S. and has been able to compromise multiple targets in the sector, according to researchers from Google Threat Intelligence Group and Google subsidiary Mandiant. 
    • “Researchers said the same threat actors linked to attacks against U.K. companies are now using well-crafted social engineering techniques against U.S. retail companies.  
    • “The threat group, tracked as UNC3944 or Scattered Spider, is widely considered the prime suspect in the attacks on British firms Harrods, Co-op and M&S, but Mandiant and Google have not formally attributed the intrusions to any specific actor. Researchers said, however, that the hackers behind the U.S. attacks share the same techniques and procedures as the intruders in the British incidents.”
  • Dark Reading adds,
    • “While dynamic DNS services have been around for many years, they’ve recently emerged as an integral tool in the arsenals of cybercriminal groups like Scattered Spider.
    • “Dynamic DNS (DDNS) services automatically update a domain name’s DNS records in real-time when the Internet service provider changes the IP address. Real-time updating for DNS records wasn’t needed in the early days of the Internet when static IP addresses were the norm.” * * *
    • “In a blog post last month, threat intelligence vendor Silent Push reported that despite some notable arrests of alleged members in 2024, Scattered Spider was actively engaged in new phishing campaigns targeting well-known enterprises. One of the key findings of the report was a shift in tactics from Scattered Spider members that featured the use of rentable subdomains from dynamic DNS providers like it.com Domains LLC.
    • “In an example of an observed attack, Scattered Spider actors established a new subdomain, klv1.it[.]com, designed to impersonate a similar domain, klv1.io, for Klaviyo, a Boston-based marketing automation company.
    • “Silent Push’s report noted that the malicious domain had just five detections on VirusTotal at the time of publication. The company also said the use of publicly rentable subdomains presents challenges for security researchers.”
  • Bleeping Computer points out,
    • “Ransomware gang members increasingly use a new malware called Skitnet (“Bossnet”) to perform stealthy post-exploitation activities on breached networks.
    • “The malware has been offered for sale on underground forums like RAMP since April 2024, but according to Prodaft researchers, it started gaining significant traction among ransomware gangs since early 2025.

David Ermer–Cybersecurity–

From the cybersecurity policy and law enforcement front,

  • Per a Senate news release,
    • “U.S. Senators Mike Rounds (R-S.D.), Chairman of the Senate Armed Services Committee’s Subcommittee on Cybersecurity, and Gary Peters (D-Mich.) introduced a bipartisan bill to extend the Cybersecurity Information Sharing Act (CISA) of 2015 for an additional ten years.
    • CISA, signed into law in 2015, incentivizes companies to voluntarily share cybersecurity threat indicators, such as software vulnerabilities, malware or malicious IP addresses, with the Department of Homeland Security (DHS). This protects Americans’ personal information and makes certain that both the federal government and companies can take collaborative steps to prevent data breaches or attacks from cybercriminals and foreign adversaries.
    • “The Cybersecurity Information Sharing Act of 2015 has been instrumental in strengthening our nation’s cyber defenses by enabling critical information sharing between the private sector and government,” said Rounds. “Allowing this legislation to lapse would significantly weaken our cybersecurity ecosystem, removing vital liability protections and hampering defensive operations across both the defense industrial base and critical infrastructure sectors.”
    • “As cybersecurity threats grow increasingly sophisticated, information sharing is not just valuable—it remains essential for our national security,” said Peters. “For the past ten years, these critical protections have helped to address rapidly evolving cybersecurity threats, and this bipartisan bill will renew them so we can continue this collaborative partnership between the private sector and government to bolster our nation’s cybersecurity defenses against a wide range of adversaries.”
    • Click HERE to read full text of the bill.
  • Cyberscoop reports,
    • “A bipartisan Senate bill would formally ban the use of DeepSeek by federal contractors, part of a larger effort to keep the Chinese-made large language model out of government systems and networks, where lawmakers fear it could pose cybersecurity and national security concerns.
    • “The bill, introduced by Sens. Bill Cassidy, R-La., and Jacky Rosen, D-Nev., would bar federal contractors from using the model to carry out any activity related to a federal contract. It also blocks contractors from using any successor model developed by High Flyer, the Chinese quantitative firm that made DeepSeek.
    • “Cassidy and Rosen cited the potential that the use of DeepSeek — which acknowledges that it sends user data back to China — to carry out contract work may put sensitive federal data in the hands of the Chinese government.
    • “AI is a powerful tool which can be used to enhance things like medicine and education,” Cassidy said in a statement. “But in the wrong hands, it can be weaponized. By feeding sensitive data into systems like DeepSeek, we give China another weapon.” 
  • and
    • “Authorities in Poland have arrested four people accused of administrating and selling access to distributed denial of service (DDoS) services, according to a press release from Europol.  
    • “The suspects are believed to have operated six so-called “stresser” or “booter” services that enabled customers across the world to launch thousands of attacks on targets ranging from government offices to businesses and schools. From 2022 to 2025, the platforms — identified as Cfxapi, Cfxsecurity, neostress, jetstress, quickdown, and zapcut — allegedly allowed users to bombard websites and servers with high volumes of junk traffic, often rendering them inaccessible. 
    • “The services, which offered easy-to-navigate interfaces, required minimal user knowledge: attackers could select a target, choose the attack specifications, and pay as little as 10 euros for each disruption, according to Europol.
    • “The arrests in Poland were part of a coordinated law enforcement response spanning four countries and supported by Europol. In addition to the Central Cybercrime Bureau in Poland, the investigation was supported by German Federal Criminal Police Office, the Prosecutor General’s Office in Frankfurt, the Dutch National Police, and multiple U.S. agencies, including the Department of Justice, FBI, Homeland Security Investigations (HSI), and Defense Criminal Investigative Service (DCIS).” 

From the cybersecurity breaches and vulnerabilities front,

  • Bleeping Computer tells us,
    • “Ascension, one of the largest private healthcare systems in the United States, has revealed that the personal and healthcare information of over 430,000 patients was exposed in a data breach disclosed last month.
    • “As Ascension revealed in breach notification letters sent to affected individuals in April, their information was stolen in a data theft attack that impacted a former business partner in December.
    • “Depending on the impacted patient, the attackers could access personal health information related to inpatient visits, including the physician’s name, admission and discharge dates, diagnosis and billing codes, medical record number, and insurance company name. They could also gain access to personal information, including name, address, phone number(s), email address, date of birth, race, gender, and Social Security numbers (SSNs).” * * *
    • “Our investigation determined on January 21, 2025, that Ascension inadvertently disclosed information to a former business partner, and some of this information was likely stolen from them due to a vulnerability in third-party software used by the former business partner.” * * *
    • “Although Ascension didn’t share any details regarding the breach affecting its former business partner, the timeline of the breach implies that the attack was part of widespread Clop ransomware data theft attacks that exploited a zero-day flaw in Cleo secure file transfer software.
    • “Last year, Ascension notified almost 5.6 million patients and employees that their personal, financial, insurance, and health information had been stolen in a May 2024 Black Basta ransomware attack.”
  • and
    • “Cisco has fixed a maximum severity flaw in IOS XE Software for Wireless LAN Controllers by a hard-coded JSON Web Token (JWT) that allows an unauthenticated remote attacker to take over devices.
    • “This token is meant to authenticate requests to a feature called ‘Out-of-Band AP Image Download.’ Since it’s hard-coded, anyone can impersonate an authorized user without credentials.
    • “The vulnerability is tracked as CVE-2025-20188 and has a maximum 10.0 CVSS score, allowing threat actors to fully compromise devices according to the vendor.”
  • Cybersecurity Dive informs us,
    • “A second wave of cyberattacks is targeting a critical vulnerability in SAP NetWeaver Visual Composer, according to researchers.
    • “Following the initial round of threat activity disclosed in April, opportunistic threat actors are leveraging webshells that were previously established through exploitation of CVE-2025-31324. The vulnerability, with a CVSS score of 10, allows unauthenticated attackers to upload arbitrary files and take full control of a system, according to researchers at Onapsis.
    • “Onapsis and Mandiant are tracking hundreds of confirmed compromises worldwide, with the cases spanning across multiple industries, including utilities, manufacturing, oil and gas and other critical infrastructure sectors. 
    • “The Cybersecurity and Infrastructure Security Agency (CISA) added the vulnerability to its known exploited vulnerabilities catalog in late April.” 
  • Cyberscoop adds,
    • “Vulnerabilities are proliferating in SonicWall devices and software this year, putting the vendor’s customers at risk of intrusion via secure access gateways and firewalls.
    • “The year started off on a sour note for the California-based company when it released security advisories for nine vulnerabilities on Jan. 7. The total number of vulnerabilities publicly disclosed by the company so far in 2025 has grown to 20. 
    • “SonicWall vulnerabilities are also making a consistent appearance on the Cybersecurity and Infrastructure Security Agency’s known exploited vulnerabilities (KEV) catalog. Cyber authorities confirm that attackers exploited four vulnerabilities in SonicWall products so far this year, and 14 total since late 2021.
    • “Eight of those vulnerabilities have been exploited in ransomware campaigns, according to CISA.”
  • Bleeping Computer adds,

From the ransomware front,

  • Dark Reading reports,
    • “Email-based attacks continued to cost enterprises big bucks in 2024, according to new cyber-insurance claims data.
    • “Cyber-insurance carrier Coalition published its “2025 Cyber Claims Report” on May 7, showing that business email compromise (BEC) attacks and fund transfer fraud (FTF) accounted for 60% of all the company’s claims last year. BEC attacks were particularly problematic for customers, according to Coalition; claims severity for such threats increased 23%, with incident’s costing organizations, on average, $35,000.
    • “That dollar figure is a far cry from the average loss for ransomware attacks in 2024, which Coalition said was $292,000. However, the claims report, which features data from customers in the US, the UK, Canada, and Australia, offered some encouraging data points, including a 7% drop in ransomware claims severity and a 3% decline in claims frequency.
    • “Additionally, Coalition found that FTF claims severity fell dramatically by 46%, to an average loss of $185,000, while claims frequency dropped 2%. Overall, the cyber-insurance carrier said it observed “remarkable year-over-year (YoY) stability” for claims, despite an intensifying threat landscape where financially motivated attackers continue to develop novel techniques and exploit new vulnerabilities.”
  • The Hacker News relates,
    • “Threat actors with ties to the Qilin ransomware family have leveraged malware known as SmokeLoader along with a previously undocumented .NET compiled loader codenamed NETXLOADER as part of a campaign observed in November 2024.
    • “NETXLOADER is a new .NET-based loader that plays a critical role in cyber attacks,” Trend Micro researchers Jacob Santos, Raymart Yambot, John Rainier Navato, Sarah Pearl Camiling, and Neljorn Nathaniel Aguas said in a Wednesday analysis.
    • “While hidden, it stealthily deploys additional malicious payloads, such as Agenda ransomware and SmokeLoader. Protected by .NET Reactor 6, NETXLOADER is difficult to analyze.”
    • “Qilin, also called Agenda, has been an active ransomware threat since it surfaced in the threat landscape in July 2022. Last year, cybersecurity company Halcyon discovered an improved version of the ransomware that it named Qilin.B.”
  • Per Bleeping Computer,
    • “The Play ransomware gang has exploited a high-severity Windows Common Log File System flaw in zero-day attacks to gain SYSTEM privileges and deploy malware on compromised systems.
    • “The vulnerability, tracked as CVE-2025-29824, was tagged by Microsoft as exploited in a limited number of attacks and patched during last month’s Patch Tuesday.
    • “The targets include organizations in the information technology (IT) and real estate sectors of the United States, the financial sector in Venezuela, a Spanish software company, and the retail sector in Saudi Arabia,” Microsoft said in April.”
  • The Wall Street Journal reports,
    • “The hacking group that once shut down half the Las Vegas Strip has returned and is causing turmoil at U.K. retailers.
    • “The hackers call themselves Star Fraud but are more widely known as Scattered Spider, a collective of largely young men and teenagers that have wreaked havoc across industries in recent years.
    • “U.K. retailers Harrods, Marks & Spencer MKS -1.05%decrease; red down pointing triangle and Co-op have all reported cyber intrusions in the past two weeks. Scattered Spider hasn’t been publicly named as the culprit of the hacks, but is suspected in at least some of them, according to people familiar with the investigation.
    • “The attacks bear all the hallmarks of Scattered Spider attacks, disrupting online sales and certain payments and leading to the theft of customer data. The stores have remained open.
    • “The group’s hackers “typically work their way through a sector, so other retailers should take the opportunity to harden their defenses,” said John Hultquist, chief analyst with Google’s Mandiant cybersecurity investigations group.” 
  • Per Cyberscoop,
    • “Five months after education software vendor PowerSchool paid an unnamed threat actor a ransom in exchange for the deletion of sensitive stolen data, some of the company’s customers are now receiving extortion demands. 
    • “A threat actor, who may or not be the same criminal group behind the attack, has contacted four school district customers of PowerSchool in the past few days, CyberScoop has learned, threatening to leak data if they don’t pay. 
    • “The downstream extortion attacks highlight the ongoing risk organizations confront when a vendor is hit by a cyberattack, exposing not just their data but also that of others in their supply chain. The follow-on extortion attempts also underscore that paying ransoms for data does not guarantee stolen data won’t be leaked.”
  • Dark Reading reports,
    • “The notorious ransomware gang LockBit appeared to suffer another setback this week after its network was compromised by an unknown adversary.
    • “On May 7, a range of security researchers observed that LockBit’s Dark Web leak site had been altered. Instead of listing victim organizations, the site now features a simple message: “Don’t do crime CRIME IS BAD xoxo from Prague,” along with a link to a zip archive.
    • “The archive, according to analysis from Qualys yesterday, among others, includes a SQL database file from LockBit’s affiliate panel. Coalition researchers, meanwhile, noted the file includes extensive internal data from the ransomware-as-a-service operation, including nearly 60,000 Bitcoin addresses and more than 4,000 chats with victim organizations from between Dec. 19, 2024, and April 29, 2025.
    • “The file also contains information on more than 70 LockBit administrators and affiliates, researchers noted, including plaintext passwords, as well individual builds and configurations of the LockBit ransomware code. However, the leaked data did not include decryptors or private keys.”

From the cybersecurity defenses front,

  • CISA announced,
    • “The Cybersecurity and Infrastructure Security Agency (CISA), Federal Bureau of Investigation (FBI), Environmental Protection Agency (EPA), and Department of Energy (DOE)—hereafter referred to as “the authoring organizations”—are aware of cyber incidents affecting the operational technology (OT) and industrial control systems (ICS) of critical infrastructure entities in the United States. The authoring organizations urge critical infrastructure entities to review and act now to improve their cybersecurity posture against cyber threat activities specifically and intentionally targeting internet connected OT and ICS.”
    • Mitigations and resources are included in the announcement.
  • Bank Info Security lets us know that “Despite the rise of artificial intelligence and automation, human ingenuity remains a critical asset in defending against cyberthreats, said Kara Sprague, CEO at HackerOne.”

From the cybersecurity and law enforcement front,

  • Cyberscoop reports,
    • “Homeland Security Secretary Kristi Noem outlined her plans Tuesday to refocus the Cybersecurity and Infrastructure Security Agency (CISA) on protecting critical infrastructure from increasingly sophisticated threats — particularly from China — while distancing the agency from what she characterized as mission drift under previous leadership.
    • “Speaking at the 2025 RSAC Conference, Noem provided the most detailed vision yet of how the current administration is pushing CISA to a “back-to-basics” approach aimed at hardening defenses against adversaries who have demonstrated capabilities to infiltrate critical systems.”
  • and
    • “Threat intelligence sharing is flowing between the private sector and federal government and remains unimpeded thus far by job losses and budget cuts across federal agencies that support the cyber mission, according to executives at major security firms.
    • “Top brass at Amazon, CrowdStrike, Google and Palo Alto Networks said there’s been no change to interactions with the federal government since President Donald Trump was inaugurated earlier this year.
    • “Across multiple interviews and media briefings during the RSAC 2025 Conference this week, none of the leaders at these top cybersecurity companies conveyed any concern about or experience with communication breakdowns. Each of them dismissed the idea that collaboration has slowed down amid significant workforce reductions and strategic changes across the federal government.”
  • Earlier this week, the National Institute of Standards and Technology released its FY 2024 Cybersecurity & Privacy Program Annual Report.
  • Federal News Network tells us,
    • “While much of the cybersecurity community’s attention was out west at the annual RSA Conference, the Justice Department announced yet another settlement in its pursuit of contractors who falsely attest to meeting cybersecurity requirements.
    • “DoJ announced today that Raytheon Company, RTX Corporation and Nightwing Group have agreed to pay $8.3 million to settle allegations that Raytheon violated the False Claims Act by falling short of contractually mandated cybersecurity standards.
    • “RTX sold its cybersecurity, intelligence and services business to Nightwing in 2024. DoJ’s case centered on conduct between 2015 and 2021, prior to the acquisition.
    • “The case is another feather in the cap for DoJ’s Civil-Cyber Fraud Initiative. Started under the Biden administration, the goal of the initiative is to enforce cybersecurity requirements that many contractors had been ignoring through the False Claims Act.”
  • Per the Hacker News,
    • “The U.S. Department of Justice (DoJ) on Thursday announced charges against a 36-year-old Yemeni national for allegedly deploying the Black Kingdom ransomware against global targets, including businesses, schools, and hospitals in the United States.
    • “Rami Khaled Ahmed of Sana’a, Yemen, has been charged with one count of conspiracy, one count of intentional damage to a protected computer, and one count of threatening damage to a protected computer. Ahmed is assessed to be currently living in Yemen.
    • “From March 2021 to June 2023, Ahmed and others infected computer networks of several U.S.-based victims, including a medical billing services company in Encino, a ski resort in Oregon, a school district in Pennsylvania, and a health clinic in Wisconsin,” the DoJ said in a statement.”
  • Cyberscoop adds,
    • “Federal authorities extradited a Ukrainian citizen to the United States on Wednesday to face charges for participating in a series of ransomware cyberattacks on organizations based in the U.S. and multiple European countries. 
    • “Artem Stryzhak, 35, was arrested in Spain in June 2024 and was scheduled to appear for arraignment Thursday in the U.S. District Court for the Eastern District of New York. Stryzhak is accused of conspiracy to commit fraud and related activity, including extortion.
    • “Prosecutors accuse Stryzhak and his co-conspirators of using Nefilim ransomware to encrypt computer networks in the U.S., Canada, France, Germany, Australia, the Netherlands, Norway and Switzerland between late 2018 to late 2021.
    • “As alleged, the defendant was part of an international ransomware scheme in which he conspired to target high-revenue companies in the United States, steal data, and hold data hostage in exchange for payment. If victims did not pay, the criminals then leaked the data online,” John Durham, U.S. attorney for the Eastern District of New York, said in a statement.”

From the cybersecurity vulnerabilities and breaches front,

  • Cybersecurity Dive reports,
    • “Hackers are increasingly using AI in their attacks and defenders should follow suit, Check Point Software Technologies said in a report published Wednesday.
    • “The company’s AI security report, announced at the 2025 RSAC Conference in San Francisco, also found that one in 13 generative AI prompts contained potentially sensitive information, and one in every 80 prompts posed “a high risk of sensitive data leakage.”
    • “Unauthorized AI tools, data loss, and AI platform vulnerabilities topped the list of AI risks for enterprises, according to Check Point.”
  • and
    • “In a report published Tuesday, Google said it saw hackers exploit fewer zero-day vulnerabilities in the wild in 2024 than in 2023.
    • “The company attributed the decrease to improvements in secure software development practices.
    • “Still, Google said it is seeing a “slow but steady” increase in the rate of zero-day exploitation over time.”
  • CISA added eight known exploited vulnerabilities to its catalog this week.

From the ransomware front,

  • Techradar points out,
    • New research has revealed the scale of recent ransomware revolution, warning it remains a dominant threat to organizations worldwide.
    • A Veeam study, which gathered insights from 1,300 CISOs, IT leaders, and security professionals across the Americas, Europe, and Australia, found nearly three-quarters of businesses were impacted by ransomware over the past year.
    • Cybersecurity measures seem to be having some effect, with businesses facing ransomware incidents dropping slightly from 75% to 69% – and ransomware payments are also decreasing, as in 2024, 36% of affected businesses chose not to pay, and 60% of those who did paid less than half of the demanded ransom.
  • Dark Reading adds,
    • “Several high-profile retailers based in the UK have suffered cyberattacks in recent weeks, and all signs point to two possible threat actors being behind the campaign.
    • “The National Cyber Security Centre (NCSC), the UK’s primary cyber agency, said on May 1 that it was tracking a series of attacks impacting retailers. NCSC CEO Dr. Richard Horne said in an included statement that the agency was working with affected organizations and that “these incidents should act as a wake-up call to all organizations.”
    • “Co-Op, Marks & Spencer, and Harrods are among the retailers that have confirmed attacks in recent weeks. In an article published May 2, Bloomberg News reported a spokesperson for the DragonForce ransomware gang — a group that emerged as a ransomware-as-a-service (RaaS) player in 2023 — took credit for the attacks against all three retailers.
    • “Last month, researchers from Sophos’ Secureworks reported that DragonForce had an RaaS model where affiliates could create their own “brand,” using DragonForce’s ransomware or using their own tools for extortion attacks.”
  • and
    • “The notorious Scattered Spider threat group continues to attack high-value targets despite landing on the receiving end of multiple global law enforcement operations.
    • “Scattered Spider gained notoriety in recent years with high-profile breaches and ransomware attacks against large enterprises, including Las Vegas casino and hotel giants Caesars Entertainment and MGM Resorts in 2023. First emerging in 2022, the group’s members displayed a knack for social engineering schemes that allowed them to steal credentials from targeted organizations and gain privileged access into their networks. * * *
    • Bleeping Computer this week reported that the cyberattack against British retail giant Marks & Spencer was perpetrated by members of the group using DragonForce ransomware. Earlier this month, threat intelligence vendor Silent Push said it had observed significant threat activity, specifically phishing campaigns targeting well-known brands this year, from Chick-fil-A to Louis Vuitton.
  • and
    • “RansomHub, an aggressive ransomware-as-a-service (RaaS) operation that gained prominence over the past year in the wake of law enforcement actions against LockBit and ALPHV, appears to have abruptly gone dark earlier this month.
    • “In a new report this week that offers an in-depth look at RansomHub’s affiliate recruitment methods, negotiation tactics, and aggressive extortion strategies, researchers at Group-IB described the operation as inactive since April 1.
    • “Cybercriminals associated with the operation may have migrated to the Russian-language speaking Qilin RaaS operation and are continuing their attacks under that banner, Group-IB said. The security vendor did not offer any explanation for the rapidly growing RansomHub operation’s seemingly sudden and unexpected demise — if that is indeed what it is.”
  • TechTarget offers a “look at the [seven] distinct stages of the ransomware lifecycle to better understand how attackers strike — and how defenders might be better able to resist.

From the cybersecurity defense front,

  • Cyberscoop reports
    • “Leaders of various federal research agencies and departments outlined a vision Tuesday for the future of critical infrastructure security, emphasizing the promise of combining formal software development methods with large language models (LLMs). 
    • “Acting DARPA Director Rob McHenry told an audience at the RSAC 2025 Conference that such a combination could “virtually eliminate software vulnerabilities” across foundational system infrastructures, a departure from the traditionally accepted risks of software flaws.
    • “We’ve all been trained in a world where we have to accept that there are vulnerabilities in our software, and bad guys exploit those vulnerabilities,” he said. “We try to mitigate the damage and patch them, and we go round on this merry-go-round. That technologically does not need to be true anymore.”
    • “DARPA’s statements came in the context of the AI Cyber Challenge, a public-private collaboration involving industry leaders such as Google, Microsoft, Anthropic and OpenAI. The initiative tests whether advanced AI systems can identify and patch vulnerabilities in open-source software components vital to the electric grid, health care, and transportation.”
  • and
    • “Cryptography experts say the race to fend off future quantum-computer attacks has entered a decisive but measured phase, with companies quietly replacing the internet plumbing that the majority of the industry once considered unbreakable.
    • “Speaking at Cloudflare’s Trust Forward Summit on Wednesday, encryption leaders at IBM Research, Amazon Web Services and Cloudflare outlined how organizations are refitting cryptographic tools that safeguard online banking, medical data and government communications. The aim is to stay ahead of quantum machines that, once powerful enough, could decode the math protecting today’s digital traffic.
    • “Over the next five to 10 years you’re going to see a Cambrian explosion of different cryptographic systems,” said Wesley Evans, a product manager for Cloudflare’s research team, referring to an evolutionary period with a rapid diversification of animal life that occurred roughly 540 million years ago.” 
  • Dark Reading adds,
    • “Each year, top SANS faculty joins the RSAC conference to present what their community of practitioners and researchers see as the most pressing challenges facing the cybersecurity community for the year to come. This year’s list of top-five threats aren’t merely technical, and tackling them will demand coordinated leadership from the very top of the organization and beyond.
    • “The attack techniques outlined in the SANS RSAC 2025 keynote underscore a common theme: Cybersecurity is no longer confined to the security operations center — it’s a leadership issue that impacts every layer of the enterprise,” according to a SANS media statement. “The threats of tomorrow demand a strategic, integrated response rooted in visibility, agility, and cross-functional alignment.”
  • Bleeping Computer notes,
    • “Microsoft has announced that all new Microsoft accounts will be “passwordless by default” to secure them against password attacks such as phishing, brute force, and credential stuffing.
    • “The announcement comes after the company started rolling out updated sign-in and sign-up user experience (UX) flows for web and mobile apps in March, optimized for passwordless and passkey-first authentication.
    • “As part of this simplified UX, we’re changing the default behavior for new accounts. Brand new Microsoft accounts will now be ‘passwordless by default’,” said Joy Chik, Microsoft’s President for Identity & Network Access, and Vasu Jakkal, Corporate Vice President for Microsoft Security.”
