W32/Rbot-RC is an IRC backdoor Trojan and network worm.

W32/Rbot-RC may spread to remote network shares protected by weak passwords and computers vulnerable to common exploits. The worm also opens up a backdoor, allowing unauthorised remote access to infected computers via the IRC network, while running in the background as a service process.

W32/Rbot-RC copies itself to the Windows system folder and creates registry entries to run itself automatically at system log-on.

W32/Rbot-RC will listen on port 113 for incoming commands such as to delete network shares, log keypresses, participate in DDoS attacks, scan other computers for vulnerabilities, steal passwords, steal registration keys for computer games and capture video from webcameras attached to infected computers.
