Daily News, Sep, 09 - massive patch tuesday

September 9th's briefing covers a record-breaking Patch Tuesday, with Microsoft releasing updates for 966 flaws, including two actively exploited zero-days. A new Microsoft Defender zero-day, ShieldCrash, grants SYSTEM-level access and requires immediate attention. Google also patched 230 Chrome vulnerabilities, marking its seventh actively exploited zero-day of the year. The sheer volume of critical patches makes for a challenging day for security teams, but the work is essential. F5 BIG-IP APM devices are also targeted by a memory-resident Linux rootkit, making detection difficult. Prioritize patching edge devices and critical systems, focusing on F5 and Chrome vulnerabilities. Audit Defender and endpoint detection logs for ShieldCrash exploit indicators. When exploring new agentic AI workflows, verify security guardrails before deploying AI-generated code.
