Detects network-based command signaling shared by the Fire Ant/REPTILE-derivative backdoor and its reverse-tunneling implant capability. Identifies the 'magic string' activation sequence and matching 'kill marker' termination sequence over TCP and UDP — indicative of packet-triggered backdoor activation, port-knocking style C2, or reverse-tunnel establishment via raw socket communication.
