- CME-540, Win32/Zotob.E!Worm [Computer A, Bozori.A [F-Secure], Net-Worm.Win32.Bozori.a [Kaspe, W32/IRCbot.worm!MS05-039 [McAf,
W32/Tpbot-A [Sophos], WORM_ZOTOB.E [Trend Micro], W32/Bozori.A [Norman]
W32.Zotob.E is a worm that opens a back door and exploits the Microsoft Windows Plug and Play Buffer Overflow Vulnerability (described in Microsoft Security Bulletin MS05-039
) on TCP port 445.
- It has been reported that computers targeted by W32.Zotob.E may become unstable during execution of the exploit code. This may result in the termination of the services.exe process, which causes the targeted computer to shutdown.
- Virus definitions version 70816y (extended version 8/16/2005 rev. 25) or greater are required to detect this risk.
- Customers running the lastest versions of Norton Internet Security, Norton AntiVirus, or Symantec AntiVirus Corporate Edition can make use of the product's automated removal functionality to remove this risk.
- While computers running Windows 95/98/Me/NT4/XP operating systems cannot be infected remotely, it is possible they could be infected if W32.Zotob.E is executed locally (although this is an unlikely occurrence). Vulnerable Windows 2000 computers could then be infected by the compromised computer.
