Description
Internet Relay Chat (IRC) is the preferred communication method used by botnet herders and remote-access trojans to control botnets (a set of scripts or an independent program that connects to IRC). IRC allows an attacker to control infected machines that are sitting behind network address translation (NAT), and the bot can be configured to connect back to the command and control server listening on any port.
