GTPDOOR

Actor(s): LightBasin


According to haxrob, GTPDOOR is the name of Linux based malware that is intended to be deployed on systems in telco networks adjacent to the GRX (GRPS eXchange Network) with the novel feature of communicating C2 traffic over GTP-C (GPRS Tunnelling Protocol - Control Plane) signalling messages. This allows the C2 traffic to blend in with normal traffic and to reuse already permitted ports that maybe open and exposed to the GRX network.
