Troj/Sdbot-CY is an IRC backdoor Trojan.

Troj/Sdbot-CY copies itself into the Windows system folder as ixplore.exe and sets the following registry entries:

HKLM\Software\Microsoft\Windows\CurrentVersion\Run\
scvhost loader = ixplore.exe

HKLM\Software\Microsoft\Windows\CurrentVersion\RunServices\
scvhost loader = ixplore.exe

Troj/Sdbot-CY logs onto a predefined IRC server and waits for backdoor commands. Depending on the commands issued by the attacker the Trojan may be able to update itself, log keystrokes, launch denial-of-service attacks, be used as a port redirector and steal licence keys of several popular online games.
