Sends the following message to all the Windows Messenger and MSN Messenger contacts on the compromised computer:

 

hot pic!!~[Link to a Web site on the mxt-networkz.com domain]/parishilton.pif~

 

Notes:

A recipient must click on the link, download the file, and then execute parishilton.pif.

The www.mxt-networkz.com domain was unavailable at the time of writing.

 

 

Drops the following files in the folder in which the worm was originally executed:

 

 

Link.exe

mafia.exe - a variant of W32.Spybot.Worm

 

 

Once executed, the W32.Spybot.Worm variant copies itself as %System%\lsassx.exe. It sets the file attributes to hidden, read only, and system.

 

 

The W32.Spybot.Worm variant adds the value:

 

"Windows Taskmanager" = "lsassx.exe"

 

to the following registry subkeys:

 

HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Run

HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\

RunServices

HKEY_CURRENT_USER\Software\Microsoft\OLE

 

so that it will execute when Windows starts.
