W32/Spybot-DR is a worm and IRC backdoor Trojan for the Windows platform.
W32/Spybot-DR runs continuously in the background, providing a backdoor server which allows a remote intruder to gain access and control over the computer via IRC channels.
W32/Spybot-DR spreads by copying itself to network shares protected by weak passwords.
When first run W32/Spybot-DR copies itself to <System>\winnt64.exe.
The following registry entries are created to run winnt64.exe on startup:
HKCU\Software\Microsoft\Windows\CurrentVersion\RunOnce
Winsock driver
winnt64.exe
HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Run
Winsock driver
winnt64.exe
