IRC Trojan is a detection for Trojans use Internet Relay Chat (IRC). The IRC connection serves as a back door, allowing an attacker to perform a variety of actions on the compromised computer. An attacker usually gathers a large number of computers infected with IRC Trojan and uses them as a bot network, controlled through IRC.
The use of IRC separates threats from their traditional back door counterparts in that the hacker does not issue commands directly to the back door. Rather they are routed through the IRC server and channel, and then on to the compromised computer. Without the IRC server or channel, the attacker is unable to control the compromised computer.
