Troj/Sdbot-DF is an IRC backdoor Trojan that has spreading capability.

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

HKLM\Software\Microsoft\Windows\CurrentVersion\Run\ktubqr = dxcqqijz.exe

HKLM\Software\Microsoft\Windows\CurrentVersion\RunServices\
ktubqr = dxcqqijz.exe

Troj/Sdbot-DF attempts to run as a service process.

Troj/Sdbot-DF logs onto a predefined IRC server and waits for backdoor commands. The spreading functionality of the Trojan can be activated by a backdoor command. When activated, the Trojan will attempt to copy itself into shares.
