More Information

W32/Forbot-E is a worm which attempts to spread to remote network shares. It also contains backdoor Trojan functionality, allowing unauthorised remote access to the infected computer via IRC channels while running in the background as a service process. W32/Forbot-E copies itself to the Windows system folder as SVXHOST.EXE and creates entries in the registry at the following locations so as to run itself on system startup:

HKLM\Software\Microsoft\Windows\CurrentVersion\Run\SVX Control Service
HKLM\Software\Microsoft\Windows\CurrentVersion\RunOnce\SVX Control Service
HKLM\Software\Microsoft\Windows\CurrentVersion\RunServices\SVX Control Service
HKCU\Software\Microsoft\Windows\CurrentVersion\Run\SVX Control Service
HKCU\Software\Microsoft\Windows\CurrentVersion\RunOnce\SVX Control Service

W32/Forbot-E also creates its own service named "Microsoft Config", with the display name "SVX Control Service".

W32/Forbot-E attempts to terminate several processes related to security and anti-virus programs.

W32/Forbot-E attempts to spread to network machines using various exploits including the LSASS vulnerability (see MS04-011).
