{“lastseen”:”2026-05-14T20:05:08″,”description”:”\\n\\nWelcome to this week’s edition of the Threat Source newsletter.\\n\\nMany solutions have been proposed to reduce software bugs: zero-defect mandates, pair programming, formal methods, and mathematical software proofs. The reality is that software engineering is _hard_. Identifying and fixing bugs before they make it into production code is _hard_. Source code peer review and extensive unit testing have improved code quality, but bugs still get through.\\n\\nNot every bug is a vulnerability, and not every fault that appears to be a vulnerability can be usefully exploited. Nevertheless, through extensive testing and review, a skilled vulnerability researcher can still uncover faults in software that has already undergone rigorous quality assurance. However, skilled vulnerability researchers are a scarce resource and can only review so much software.\\n\\nAI is the great hope for improving software quality. Iterative improvements in AI’s ability to find bugs mean that each new version of these systems is better than the last. We’re now at the point where AI, although still not as good as a skilled vulnerability researcher, can scan code to find errors at a scale and speed that human analysis cannot match. Used well, it can identify potential vulnerabilities before they reach production.\\n\\nIn the long term, this is very good news. Better automated review and analysis of software is how we will improve code quality. However, in the short term, decades of technical debt and latent errors will be uncovered and will need to be addressed. To make things more complex, threat actors will have access to these same tools to search for exploitable vulnerabilities for their own ends.\\n\\nThe result is likely to be a surge in patches. More vulnerabilities discovered means more fixes released, placing additional pressure on already stretched operations teams. Many of these patches will be urgent; some will address vulnerabilities that are being actively exploited. Without proper planning, the volume of fixes may outpace an organization’s capacity to deploy them.\\n\\nThe surge of patches has yet to happen, but the first signs may already be visible. Now is an excellent time to consider how you prioritise patching, apply patches at scale, and manage systems that cannot be patched quickly — or at all. We can reflect on these questions now, and improve our processes, or we can flounder when the surge of patches arrives. Either way, ready or not, the time of much patching is coming.\\n\\n## The one big thing\\n\\nIn Cisco Talos’ _latest blog_, we outline the differences between responding to state-sponsored threat actors and handling commodity ransomware. These advanced adversaries log in using valid credentials and leverage your own trusted tools to remain invisible for months. Because their primary objectives are long-term espionage and pre-positioning rather than immediate financial gain, standard incident response playbooks are entirely inadequate.\\n\\n### Why do I care?\\n\\nState-sponsored actors operate inside your trust boundary and aim to remain completely undetected. They have the patience and resources to map your infrastructure, exploit supply chain vulnerabilities, and blend their lateral movement into routine administrative tasks. If your security architecture assumes internal traffic is inherently trustworthy, these adversaries will exploit that gap to establish deep, persistent access across both IT and operational technology environments. Prematurely containing these threats can even tip off the attacker, causing you to lose critical intelligence and the chance to fully eradicate their foothold.\\n\\n### So now what?\\n\\nShift to a zero trust architecture that continuously verifies access and plans for inevitable failures, starting with maximizing your visibility through centralized log aggregation and enabling Windows command-line and PowerShell script block logging. Prioritize identity management by enforcing multi-factor authentication on all administrative accounts and implementing a tiered access model. Update your incident response playbooks to specifically address living-off-the-land techniques, supply chain compromises, and the complex operational timing required for state-sponsored containment. _Read the blog here for more information._\\n\\n## Top security headlines of the week\\n\\n**Linux bitten by second severe vulnerability in as many weeks** \\nThe leaked exploit is deterministic, meaning it works precisely the same way each time it’s run and across different Linux distributions. It causes no crashes, making it stealthy to run. Install patches immediately. (_Ars Technica_)\\n\\n**A DOD contractor ‘s API flaw exposed military course data and service member records** \\nThe issue affected Schemata, an AI-powered virtual training platform used in military and defense settings. According to Strix, an ordinary low-privilege account was able to access data across multiple tenants. (_CyberScoop_)\\n\\n**Fake OpenAI Privacy Filter repo hits No. 1 on Hugging Face, draws 244K downloads** \\nA malicious repository managed to take a spot in the platform’s trending list by impersonating OpenAI’s Privacy Filter open-weight model to deliver a Rust-based information stealer to Windows users. (_The Hacker News_)\\n\\n**TanStack, Mistral AI, UiPath hit in fresh supply chain attack** \\nThe same as in previous campaigns, the worm targets sensitive information, including developer credentials, API keys, tokens, cloud credentials and secrets, cryptocurrency wallets, and more. (_SecurityWeek_)\\n\\n**Official CheckMarx Jenkins package compromised with infostealer** \\nCheckmarx warned over the weekend that a rogue version of its Jenkins Application Security Testing (AST) plugin had been published on the Jenkins Marketplace. (_BleepingComputer_)\\n\\n## Can’t get enough Talos?\\n\\n** _Breaking things to keep them safe with Philippe Laulheret_** \\nFrom his memorable experiment using a green onion to bypass a biometric fingerprint reader to his experience on the frontlines of cybersecurity, Philippe shares the journey that led him to vulnerability research.\\n\\n** _Inside the SOC: AI-powered DNS defense against ransomware_** \\nLearn how Cisco Talos’ advanced AI-driven detection, including domain generation algorithm (DGA) analysis, integrates within Cisco Secure access to proactively identify and predict malicious domains.\\n\\n** _Clustering and reuse of phone numbers in scam emails_** \\nCisco Talos has recently started to collect and gather intelligence around phone numbers within emails as an additional indicator of compromise (IOC). In this blog, we discuss new insights into in-the-wild phone number reuse in scam emails. ****\\n\\n## Upcoming events where you can find Talos\\n\\n * _OffensiveCon_ (May 15 – 16) Berlin, Germany\\n * _Cisco Live U.S._ (May 31 – June 4) Las Vegas, Nevada\\n\\n\\n\\n## Most prevalent malware files from Talos telemetry over the past week\\n\\n**SHA256: 9f1f11a708d393e0a4109ae189bc64f1f3e312653dcf317a2bd406f18ffcc507** \\nMD5: 2915b3f8b703eb744fc54c81f4a9c67f \\nTalos Rep: _https:\/\/talosintelligence.com\/talos_file_reputation?s=9f1f11a708d393e0a4109ae189bc64f1f3e312653dcf317a2bd406f18ffcc507_ \\nExample Filename: VID001.exe \\nDetection Name: Win.Worm.Coinminer::1201**\\n\\n**SHA256: 96fa6a7714670823c83099ea01d24d6d3ae8fef027f01a4ddac14f123b1c9974** \\nMD5: aac3165ece2959f39ff98334618d10d9 \\nTalos Rep: _https:\/\/talosintelligence.com\/talos_file_reputation?s=96fa6a7714670823c83099ea01d24d6d3ae8fef027f01a4ddac14f123b1c9974_ \\nExample Filename: d4aa3e7010220ad1b458fac17039c274_63_Exe.exe \\nDetection Name: W32.Injector:Gen.21ie.1201\\n\\n**SHA256: e60ab99da105ee27ee09ea64ed8eb46d8edc92ee37f039dbc3e2bb9f587a33ba** \\nMD5: dbd8dbecaa80795c135137d69921fdba \\nTalos Rep: _https:\/\/talosintelligence.com\/talos_file_reputation?s=e60ab99da105ee27ee09ea64ed8eb46d8edc92ee37f039dbc3e2bb9f587a33ba_ \\nExample Filename: u112417.dat \\nDetection Name: W32.Variant:MalwareXgenMisc.29d4.1201\\n\\n**SHA256: 90b1456cdbe6bc2779ea0b4736ed9a998a71ae37390331b6ba87e389a49d3d59** \\nMD5: c2efb2dcacba6d3ccc175b6ce1b7ed0a \\nTalos Rep: _https:\/\/talosintelligence.com\/talos_file_reputation?s=90b1456cdbe6bc2779ea0b4736ed9a998a71ae37390331b6ba87e389a49d3d59_ \\nExample Filename: APQ9305.dll \\nDetection Name: Auto.90B145.282358.in02″,”published”:”2026-05-14T18:00:24″,”modified”:”2026-05-14T18:00:24″,”type”:”talosblog”,”title”:”The time of much patching is coming”,”source”:””,”references”:””,”id”:”TALOSBLOG:5789026EF53D30E3F9C3E6C8927FC37B”,”bulletinFamily”:”blog”,”cwe”:null,”cvelist”:[],”sourceData”:””,”sourceHref”:””,”cvss”:{“score”:0,”severity”:”NONE”,”vector”:”NONE”,”version”:”NONE”},”cvss2″:{},”cvss3″:{“version”:””,”vectorString”:””,”baseScore”:0,”baseSeverity”:””,”attackVector”:””,”attackComplexity”:””,”privilegesRequired”:””,”userInteraction”:””,”scope”:””,”confidentialityImpact”:””,”integrityImpact”:””,”availabilityImpact”:””,”cvssV3″:{“version”:””,”vectorString”:””,”baseScore”:0,”baseSeverity”:””,”attackVector”:””,”attackComplexity”:””,”privilegesRequired”:””,”userInteraction”:””,”scope”:””,”confidentialityImpact”:””,”integrityImpact”:””,”availabilityImpact”:””}},”href”:”https:\/\/blog.talosintelligence.com\/the-time-of-much-patching-is-coming\/”,”category_name”:”News”,”post_link”:””,”product”:””,”version”:””,”vendor”:””,”ai_description”:””,”ai_severity”:””,”ai_vendor”:””,”ai_product”:””,”ai_version”:””,”ai_score”:0}<\/p>\n","protected":false},"excerpt":{"rendered":"
