Summary
A nation-state affiliated cyber threat actor has compromised F5 systems and exfiltrated data, including portions of the BIG-IP proprietary source code and vulnerability information, which provides the actor with a technical advantage to exploit F5 devices and software. This poses an imminent threat to federal networks using F5 devices and software. Inventory: Identify all instances of F5 BIG-IP hardware devices and F5OS, BIG-IP TMOS, Virtual Edition, BIG-IP Next, BIG-IP IQ software, and BNK / CNF. Harden Public-Facing Hardware and Software Appliances: Identify if physical or virtual BIG-IP devices exposed to the public internet provide public access to the networked management interface. Disconnect End of Support Devices: Disconnect all public-facing F5 devices that have reached their end-of-support date.
