About this tag
The backdoor persistence tag on WindowsForum covers threats where attackers implant lasting access mechanisms that survive remediation efforts like patching or firmware updates. A key example discussed is the FIRESTARTER backdoor targeting Cisco ASA and Firepower devices, which works alongside malware like LINE VIPER to maintain a foothold even after the original vulnerability is fixed.
