More Information
W32/Sdbot-ZX is an internet worm and IRC backdoor Trojan for the Windows platform.
W32/Sdbot-ZX spreads:
- via IRC channels
- to other network computers infected with W32/MyDoom
- by copying itself to network shares protected by weak passwords
W32/Sdbot-ZX 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/Sdbot-ZX includes functionality to:
- steal confidential information
- carry out DDoS flooder attacks
- provide a proxy server
- silently download, install and run new software
When first run W32/Sdbot-ZX copies itself to <System>\ntbstats.exe.
The following registry entries are created to run ntbstats.exe on startup:
HKLM\Software\Microsoft\Windows\CurrentVersion\Run
NET Bios Stats
ntbstats.exe
HKLM\Software\Microsoft\Windows\CurrentVersion\RunServices
NET Bios Stats
ntbstats.exe
