Technical Details

Riskware:W32/mIRC is an Internet Relay Chat (IRC) client that can be silently subverted by malware to become a backdoor. By itself, the program is not malicious.

Activity

Malware such asBackdoor:W32/Zapchast and its variants can use malicious configuration files to turn the mIRC-client into a backdoor. The malicious configuration files are detected as Backdoor.IRC.Zapchast.

In addition to subverting the mIRC client, these files will also contain the name of an IRC channel which the mIRC-client will automatically try to join on each startup.

Sometimes, Zapchast variants will use additional batch files which provide added functionality, such as performing registry changes to create a launchpoint for the backdoor. These auxiliary batch files are detected as Trojan.BAT.Zapchast.
