A new, sophisticated malware dubbed Firestarter is compromising Cisco Firepower and Secure Firewall devices, establishing a persistent foothold that survives reboots, firmware updates, and security patches. Linked to state-sponsored actor UAT-4356, this threat requires a full device reimage, not just patching, to mitigate the risk of long-term network compromise.
