Technical Details

Breplibot is an IRC bot-based backdoor. After being started, it installs itself to the system, creates a startup key for itself in the Registry, connects to several IRC servers, and waits for commands from a remote hacker. The backdoor can delete, download, and run files on an infected computer. It also terminates the processes of several security-related software packages.
