HOW THE F5 BREACH, CISA JOB CUTS, AND A GOVERNMENT SHUTDOWN ARE ERODING US CYBER READINESS

Summary from the TLDR InfoSec newsletter

A China-linked breach of F5's BIG-IP software exposed source code and undisclosed vulnerabilities, creating a path for custom exploits against critical infrastructure and government networks. At the same time, significant workforce cuts at CISA and a federal shutdown are degrading incident response capacity, election protection efforts, and national coordination. Security teams should assume reduced federal support and prioritize proactive hardening, continuous monitoring, and supply chain risk management across high-impact edge and network devices.
