Linux Backdoors Impersonate Email Security Tools to Evade Detection in Korea and Taiwan

What happened

Linux backdoors (a hidden way into a system that bypasses its login) targeting telecom and network appliances in South Korea and Taiwan have been disguising their traffic as email services and seemingly legitimate processes to blend in and evade detection. Threat actors are known to name their malicious software after a legitimate operating system component or a process as a defense evasion measure.
