CISA’s Emergency Directive ED 26-01 is here to rescue F5 devices from cyber villains. Federal agencies must inventory their F5 BIG-IP products, secure public interfaces, and update to the latest F5 software by October deadlines. Forget to update? You might as well hand hackers your passwords on a silver platter.

Hot Take:

In the latest episode of “Cybersecurity: The Never-Ending Saga,” CISA swoops in with an emergency directive to save the day from a nation-state hacker who’s gone full ‘Mission Impossible’ on F5 devices. It’s time for the federal networks to tighten their digital belts and prepare for the ultimate game of whack-a-mole with hackers. Remember folks, just like socks in the laundry, vulnerabilities have a mysterious way of multiplying!

Key Points:

  • Federal agencies must inventory all F5 BIG-IP products and assess if they have public internet exposure.
  • Harden and update all F5 devices and software using the latest vendor updates by specified deadlines.
  • Disconnect any public-facing F5 devices that are no longer supported, unless mission-critical.
  • Mitigate any cookie leakage vulnerabilities as per CISA’s instructions.
  • Complete an inventory report of F5 products and submit actions taken to CISA by the end of October 29, 2025.
