Security A Chinese APT codenamed UAT-4356 has been living inside Cisco ASA and Firepower firewalls through two complete patch cycles using a previously unknown backdoor called FIRESTARTER — discovered by CISA, which has now ordered federal agencies to submit memory snapshots immediately.
A Chinese APT survived two full patch cycles on Cisco firewalls using a backdoor that only a hard power-cycle and reimage can remove, a CVSS 9.1 ASP.NET Core auth bypass lets forged tokens persist eve…
