More Information
W32/Agobot-TG is a worm and IRC backdoor Trojan for the Windows platform.
W32/Agobot-TG 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-TG 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-TG copies itself to <System>\svchost32.exe.
The following registry entries are created to run svchost32.exe on startup:
HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Run
Services Host
svchost32.exe
HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\RunServices
