The Register - Anti-Virus

Crims found the soft spot in the company's security. MyPillow, the US-based bedding brand founded by election conspiracy theorist Mike Lindell, has been listed by Play ransomware extortionists as an alleged victim. The pillow shop first appeared on Play’s name-and-shame data leak site on Monday, with the gang threatening to leak stolen data by Friday if MyPillow execs don’t pay the ransom demand. While the extortionists didn’t specify how many gigabytes of data they allegedly stole from MyPillow, they claim it includes “private and personal confidential data, client documents, budget, payroll, IDs, taxes, finance information” and more, according to the dark-web post seen by The Register and shared on social media by threat-intel firm FalconFeeds. MyPillow did not immediately respond to The Register’s inquiries. We will update this story if we receive any response. As of May 2025, the FBI said Play ransomware operators had allegedly exploited about 900 organizations, and the crew’s ransomware variant consistently ranks among the top five targeting critical infrastructure. Play previously stole around 65,000 Swiss government files after breaching its IT supplier Xplain in 2023. A year later, the group hacked Microchip Technology. The American semiconductor manufacturer told regulators that the ransomware attack disrupted some of its business operations and cost it $21.4 million in expenses related to the security incident. North Korean government goons have also used Play ransomware in their intrusions. Cisco Talos' incident responders previously told The Register that Play was one of the crews that used so-called "EDR killers" to disable endpoint security products in their ransomware infections. MyPillow is probably best known for its founder and CEO's politics. Lindell is a major proponent of President Trump’s false claims that the 2020 election was stolen, and is now running for Minnesota governor. ®

National security and digital forensics experts have called foul on Nigel Farage's "disturbing" and unsubstantiated claim that Russia was behind the leak of a story about the UK politician receiving a £5 million gift from a crypto billionaire. Sources inside Farage's right-wing Reform UK told the Mail on Sunday that the party leader believes Russian spies hacked his phone and relayed details about Christopher Harborne's gift, a matter of which only four people were aware. Farage was said to have engaged outside "counter-espionage experts" to perform a technical analysis of his device – analysis that was said to point to Russia. According to Peter Sommer, professor of digital forensics at Birmingham City University, whichever outfit was entrusted to carry out this work would have been looking for two different types of markers to prove Russia was involved. These would be either the phishing message Farage clicked on that allowed Russia to access his private communications or the malware code an attacker used to exfiltrate them. "It's obviously trivial to disguise the source of an email, so that doesn't help," Sommer told The Register. "And the second thing is if you're talking about looking for hacking codes, hackers, whether they are juveniles or people in major SIGINT systems, are likely to be stealing from each other, so there's nothing unique about a code that would say where it comes from." Sommer also highlighted that advanced intelligence powers have tools at their disposal to obfuscate the source of malicious code. The CIA's leaked Marble Framework supposedly had the ability to translate malicious code into any language, including those used by its chief adversaries. "Now, absent from that, how on Earth do you determine that this is a Russian hack?" Sommer asked. Neither Farage nor Reform UK has spoken officially on the alleged Russian phone hack. They have not specified which experts on whose conclusions they used to make the claims, they have not stated what evidence pointed to Russia's involvement, and they have not committed to making this forensic assessment available for public scrutiny. Opening up the data for verification was one of the core issues raised by Ciaran Martin, founding chief executive of the UK's National Cyber Security Centre (NCSC), who labeled Farage's claims "disturbing" and "without any merit." Speaking to The Guardian, Martin said that not only is the lack of clear evidence concerning, but also if Russia was behind the hack-and-leak operation, a deliberate attempt at destabilizing a foreign democracy, then it would have significant consequences for the UK's Russia policy. "An aspiring prime minister has essentially claimed that Russia has launched an unprecedentedly aggressive intervention – a malicious intervention – in British politics, and he's not produced a shred of evidence to support that claim," Martin said. "It is a very, very serious thing to allege. It would be a national security issue," he added. "If it is true, the government should be in emergency session in COBR right now, considering their response to the most serious Russian intervention in internal British affairs for years." He said the claims published by the Mail on Sunday, at present, are unsubstantiated, and if true, in normal circumstances, this would prompt a formal government response. The Reg understands that the NCSC has not been engaged by Farage or Reform UK over the matter. The National Crime Agency did not respond to questions regarding its involvement and the Metropolitan Police Service declined to comment. Reform UK did not respond to our requests for more information, nor did Nigel Farage's office. What exactly did Reform UK claim? According to sources who spoke to the Mail on Sunday, Russian spies hacked Farage's phone, ascertained details about Harborne's £5 million donation to the party leader, and leaked it to The Guardian, which first reported the story. The Guardian said at the weekend that Farage is now under "mounting pressure" to prove his claim about the Russian phone hack. There is no indication the Graun 's reporting was connected to any illegal activity or Russian spies, but Farage is implying so, telling the Mail on Sunday: "This shocking revelation brings into question The Guardian’s judgment and whether Reform can cooperate with them in future." According to the analysis of Farage's phone, carried out by the unidentified counter-espionage experts, the findings were "almost certainly linked to Moscow," the Reform UK source said. They also claimed that spear-phishing tactics were used to compromise his phone, email, and bank accounts. "It bore all the sophisticated hallmarks of a nation-state actor using destabilization techniques in the run-up to this month's local elections," the source added. Farage said: "These actions by Russia are deeply concerning and highlight the threat they pose to British security." Regarding the motive for such an attack, Reform UK believes its leader angered Russian president Vladimir Putin by previously expressing support for NATO. He has said in the past that UK forces should shoot down Russian aircraft if they enter NATO airspace, and joined controversial calls for Ukraine to be admitted to the military alliance. The party also said that Harborne may be a target for the Russian regime because he joined former prime minister Boris Johnson on a trip to Ukraine in 2022, designed to showcase the impact of Russia's invasion earlier that year. ®

Anthropic has revealed its intention to one day release models that match the performance of its Mythos bug-finding AI to the public, once it can make them safe. In case you came in late, in early April Anthropic announced it had developed a model called Mythos that is so good at finding security vulnerabilities in programming code that the company decided to offer it only to select entities because allowing unfettered access would mean cybercriminals could quickly discover and exploit software flaws. That access program is called “Project Glasswing” and participants report it quickly finds many bugs but few that humans couldn’t find given enough time and resources. Those with access to Mythos have also sometimes said the quantity of bugs it finds somewhat overwhelms their ability to patch them all. The mere existence of Mythos has sparked a little panic – Japan’s government ordered a sweeping security review and Indian authorities demanded a patching spree at financial institutions – plus a general realization that even lesser AI models are also decent bug-finders, meaning cyber-defenders must now expect attackers will weaponize more flaws, more often. No company—including Anthropic—has developed safeguards strong enough to prevent such models from being misused Anthropic last week published an “initial update” on Project Glasswing that in its second-to-last paragraph reveals the company’s next step will see it “… work with critical partners – including US and allied governments – to expand Project Glasswing to additional partners. And in the near future, once we’ve developed the far stronger safeguards we need, we look forward to making Mythos-class models available through a general release.” The company didn’t explain what it means by “near future” and admits that “At present, no company—including Anthropic—has developed safeguards strong enough to prevent such models from being misused and potentially causing severe harm.” Further illustration of that assertion can be found earlier in the company’s post, which reveals that Anthropic has used Mythos to scan more than 1,000 open-source projects that it says “collectively underpin much of the internet – and much of our own infrastructure.” To date, Mythos has found an estimated 6,202 high-or-critical-severity vulnerabilities in these projects – and 23,019 flaws in all. The post reveals that when Mythos finds a flaw, Anthropic and its pals in the security community reproduce the issue that Mythos has found and “re-assess its severity.” “Once we’ve confirmed that a vulnerability is real, we check for whether there are already fixes in place, and write a detailed report to the software’s maintainers,” Anthropic explains. “We take considerable care here: on top of the regular challenges of maintaining open-source software, maintainers have been facing a deluge of low-quality, AI-generated bug reports. Indeed, several maintainers have told us they’re currently severely capacity constrained, and some have even asked us to slow down our rate of disclosures because they need more time to design patches.” 1,752 of the high-or-critical-rated vulnerabilities Mythos found in FOSS have gone through that process and 90.6 percent (1,587) proved to be valid flaws. Of those, 62.4 percent (1,094) “were confirmed as either high-or-critical-severity,” the post states. One of the critical flaws impacted the wolfSSL cryptography library used by billions of devices worldwide. “Mythos Preview constructed an exploit that would let an attacker forge certificates that would (for instance) allow them to host a fake website for a bank or email provider,” Anthropic wrote. “The website would look perfectly legitimate to an end user, despite being controlled by the attacker.” Thankfully, developers have already patched wolfSSL, and Anthropic said it will deliver a full technical analysis “in the coming weeks.” Keep an eye out for CVE-2026-5194 to learn more about this one. Mythos is adding to an already overloaded security ecosystem “75 of the 530 high-or-critical-severity bugs we’ve reported have now been patched, and 65 of those have been given public advisories,” the post states, then explains that low fix rate by revealing Anthropic is “still early in the 90-day window that’s set out in our Coordinated Vulnerability Disclosure policy: we expect many more patches to land soon.” The company thinks it is also “likely to be undercounting patches because some vulnerabilities are patched without a public advisory.” Lastly, the flood of bugs Mythos found “is adding to an already overloaded security ecosystem.” Anthropic’s suggestion for security teams struggling to develop fixes for bugs AI discovered is, unsurprisingly, more AI such as skills that improve its Claude model’s ability to help developers. ®
