49,000 malicious downloads served before removal\n- Storm-0940 used AI pentest framework Artex to compromise 300+ Microsoft Entra tenants across eight organizations\n- APT41 BlackX UEFI bootkit bypassed Secure Boot on fully patched Windows systems targeting Central Asian diplomats\n- Sandworm and UAC-0099 combined a new mesh-network backdoor with a destructive wiper against Ukrainian logistics infrastructure\n- Quest Diagnostics and Capcom (11.7M records) confirmed breaches; MFA bypassed at 79 organizations via session token replay\n\n### Why it matters for defenders and leaders\nThe signal this week is velocity: attackers weaponized PHP2Shell before disclosure, ran covert LiteLLM exfiltration workflows for 11 days before detonation, and used AI to compress multi-week intrusion campaigns into hours. Defenders relying on patch cadence alone or on MFA as a terminal control are operating with false confidence.\n\n- Session token replay bypassed MFA at 79 organizations with no credential theft required\n- AI pentest frameworks now automate full kill chains at machine speed, accessible to nation-state and criminal actors alike\n- Supply chain compromise via leaked secrets persisted undetected for weeks inside trusted repositories\n- UEFI bootkits bypass Secure Boot even on fully patched systems when revocations are not manually applied\n\n### What to do this week\n- Patch PHP to the latest release, apply `session.upload_progress.enabled=0` as interim mitigation for CVE-2026-115560, and upgrade Node.js runtimes across all environments including containers and serverless\n- Audit all Python environments that installed LiteLLM between October 10 and 23, rotate every credential that environment had access to, and verify no malicious Python startup hooks remain\n- Review Microsoft Entra for unexpected OAuth application credential changes, newly registered MFA methods, and suspicious device registrations linked to the Storm-0940 ConnectWise campaign\n- Manually apply UEFI Secure Boot revocation updates on Windows endpoints to block the Baton Drop exploit vector used by BlackX\n- Patch Arista VeloCloud Orchestrator and Collabora Online CODE Server immediately; both have confirmed active exploitation and federal remediation deadlines of October 26","AI pulled the trigger and supply chains loaded the gun","https:\u002F\u002Fcdn.threatnoir.com\u002Fweekly\u002F2026-w43-cover.png",{"https:\u002F\u002Fcybersecuritynews.com\u002Fclaude-mythos-5-inject-malicious-code\u002F":133,"https:\u002F\u002Fcybersecuritynews.com\u002Fsbi-notifies-customers-with-cyber-incident\u002F":134,"https:\u002F\u002Fnoyb.eu\u002Fen\u002Fai-eu-member-states-approve-digital-expropriation-europeans-ai-companies":135,"https:\u002F\u002Fsecurityaffairs.com\u002F201538\u002Fhacking\u002Fphp2shell-millions-of-attacks-no-confirmed-successful-exploits-yet.html":136,"https:\u002F\u002Fsecurityaffairs.com\u002F201582\u002Flaws-and-regulations\u002Fmeta-faces-25-billion-penalty-linked-to-cambridge-analytica-scandal.html":137,"https:\u002F\u002Fsecurityaffairs.com\u002F201626\u002Fdata-breach\u002Fcapcom-data-breach-exposes-11-7-million-email-addresses.html":138,"https:\u002F\u002Fthehackernews.com\u002F2026\u002F10\u002Fblackx-uefi-bootkit-bypasses-secure.html":139,"https:\u002F\u002Fthehackernews.com\u002F2026\u002F10\u002Fbrotli-decoder-flaw-behind-nodejs-rce.html":140,"https:\u002F\u002Fthehackernews.com\u002F2026\u002F10\u002Fcisa-flags-two-actively-exploited.html":141,"https:\u002F\u002Fthehackernews.com\u002F2026\u002F10\u002Fcritical-flaw-in-pythons-popular-pillow.html":142,"https:\u002F\u002Fthehackernews.com\u002F2026\u002F10\u002Fexposed-infrastructure-reveals-how.html":143,"https:\u002F\u002Fthehackernews.com\u002F2026\u002F10\u002Fleaked-litellm-master-key-let-attackers.html":144,"https:\u002F\u002Fthehackernews.com\u002F2026\u002F10\u002Frussian-linked-hackers-used-new-mesh.html":145,"https:\u002F\u002Ftherecord.media\u002Fuk-undersea-cables-sabotage-new-sentencing-guidelines":146,"https:\u002F\u002Fwww.bleepingcomputer.com\u002Fnews\u002Fsecurity\u002Fhpe-patches-eight-max-severity-rce-and-auth-bypass-aos-flaws\u002F":147,"https:\u002F\u002Fwww.bleepingcomputer.com\u002Fnews\u002Fsecurity\u002Fquest-diagnostics-confirms-data-breach-exposed-patient-records\u002F":148,"https:\u002F\u002Fwww.helpnetsecurity.com\u002F2026\u002F10\u002F23\u002Fmicrosoft-365-accounts-stolen-sessions\u002F":149,"https:\u002F\u002Fwww.microsoft.com\u002Fen-us\u002Fsecurity\u002Fblog\u002F2026\u002F10\u002F23\u002Finside-the-litellm-1-107-0-supply-chain-compromise-credential-theft-through-python-startup-hooks\u002F":150,"https:\u002F\u002Fwww.securityweek.com\u002Fatlassian-patches-75-third-party-flaws-in-data-center-and-server-products\u002F":151,"https:\u002F\u002Fwww.securityweek.com\u002Fchina-apt-uses-ai-pentest-tool-artex-in-connectwise-attacks\u002F":152,"https:\u002F\u002Fwww.stepsecurity.io\u002Fblog\u002Fovhcloud-cli-github-release-swap-glassworm":153,"https:\u002F\u002Fwww.theregister.com\u002Fsecurity\u002F2026\u002F10\u002F23\u002Ftheres-a-third-php2shell-bug-but-it-wont-get-an-emergency-fix\u002F5305208":154},"anthropic-s-claude-mythos-5-ai-agent-tried-to-inject-malicious-code-and-trick-re-29f7cb","sbi-notifies-customers-impacted-by-the-recent-cyber-incident-18845b","ai-eu-member-states-approve-digital-expropriation-for-ai-companies-4238ef","php2shell-millions-of-attacks-no-confirmed-successful-exploits-yet-5534c9","meta-faces-25-billion-penalty-linked-to-cambridge-analytica-scandal-2d916a","capcom-data-breach-exposes-11-7-million-email-addresses-39668b","blackx-uefi-bootkit-bypasses-secure-boot-on-patched-windows-systems-missing-revo-68f2c8","brotli-decoder-flaw-behind-node-js-rce-also-affects-bun-python-and-other-widely-a64123","cisa-flags-two-actively-exploited-critical-flaws-in-collabora-online-and-arista-ad7396","critical-flaw-in-python-s-popular-pillow-image-library-allows-code-execution-via-e21e41","exposed-infrastructure-reveals-how-ransomware-affiliates-used-ai-agents-to-execu-6fb95e","leaked-litellm-master-key-let-attackers-steal-github-tokens-and-hijack-release-p-c2f353","russian-linked-hackers-used-new-mesh-network-backdoor-in-destructive-ukraine-att-76da60","uk-proposes-14-year-prison-terms-for-undersea-cable-sabotage-7606bf","hpe-patches-eight-max-severity-rce-and-auth-bypass-aos-flaws-690940","quest-diagnostics-confirms-data-breach-exposed-patient-records-5d9f1f","microsoft-365-accounts-compromised-at-79-organizations-no-passwords-needed-d00a5f","inside-the-litellm-1-107-0-supply-chain-compromise-credential-theft-through-pyth-e59453","atlassian-patches-75-flaws-in-data-center-and-server-products-87fa2c","china-apt-uses-ai-pentest-tool-artex-in-connectwise-attacks-28839f","ovhcloud-cli-compromised-via-github-release-swap-detonating-the-real-glassworm-l-840021","there-s-a-third-php2shell-bug-but-it-won-t-get-an-emergency-fix-77a47a"]
