More Information
W32/Agobot-TK is a worm and IRC backdoor Trojan for the Windows platform.
W32/Agobot-TK spreads to other network computers by exploiting common buffer overflow vulnerabilites, including: PNP (MS05-039) and ASN.1 (MS04-007) and by copying itself to network shares protected by weak passwords.
W32/Agobot-TK 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.
When first run W32/Agobot-TK copies itself to <System>\v1rg1n.exe.
The following registry entries are created to run v1rg1n.exe on startup:
HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Run
SvcHosto
v1rg1n.exe
HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\RunServices
