Background for this topic.
F5 provides application-delivery technology, best known in security operations for BIG-IP appliances and software that load-balance traffic, terminate TLS, route requests, and can enforce web-application firewall, access-control, and denial-of-service protections. F5’s NGINX products are also used as reverse proxies and web servers. These components sit in front of applications, mediating internet traffic and trust boundaries.
Their privileged position makes exposed management interfaces, insecure configurations, leaked certificates or keys, and unpatched vulnerabilities especially significant: compromise can enable traffic interception, authentication bypass, request manipulation, or access to protected applications, depending on deployment. Security teams should inventory BIG-IP and NGINX instances and versions, restrict management planes, apply vendor fixes, review iRules, WAF, and access policies, and monitor administrative and anomalous proxy activity. During incidents, preserve configuration and traffic logs and assess whether TLS credentials or backend routes were exposed.

F5 has released security updates to address two critical security flaws in NGINX Open Source that could be exploited to achieve code execution on affected systems
The U.S. Cybersecurity and Infrastructure Security Agency (CISA) on Friday added a critical security flaw impacting F5 BIG-IP Access Policy Manager (APM) to its Known Exploited Vulnerabilities (KEV) catalog, citing evidence of active exploitation
Security, trust, and stability — once the pillars of our digital world — are now the tools attackers turn against us. From stolen accounts to fake job offers, cybercriminals keep finding new ways to exploit both system flaws and human behavior
It’s easy to think your defenses are solid — until you realize attackers have been inside them the whole time. The latest incidents show that long-term, silent breaches are becoming the norm. The best defense now isn’t just patching fast, but watching smarter and staying alert for what you don’t expect
