What it detects

This rule detects Linux command lines that disable SELinux with setenforce 0 or turn off the UFW firewall, defense-impairment steps the 8220 Gang runs before deploying its Linux miner and IRC bot. Weakening host protections clears the way for cryptomining and lateral spread. Detecting these commands surfaces attacker tampering with Linux security controls.
