More Information
W32/Agobot-TX is a worm and IRC backdoor Trojan for the Windows platform.
W32/Agobot-TX spreads to other network computers by exploiting common buffer overflow vulnerabilities, including: RPC-DCOM (MS04-012) and PNP (MS05-039) and by copying itself to network shares protected by weak passwords.
W32/Agobot-TX 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-TX copies itself to <System>\stisvc32.exe.
The following registry entries are created to run stisvc32.exe on startup:
HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Run
PDA Commander
stisvc32.exe
HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\RunServices
PDA Commander
stisvc32.exe
W32/Agobot-TX attempts to modify the HOSTS file located at
<System>\Drivers\etc\HOSTS, mapping selected anti-virus websites to the loopback address 127.0.0.1 in an attempt to prevent access to these sites.
