Technical Details

This worm spreads via file-sharing networks. The worm itself is a Windows PE EXE file approximately 1274KB in size.


Once launched, the worm causes the following error message to be displayed:

On repeated launched, the worm will cause the error message below to be displayed:

When installing, the worm copies itself to the Windows root directory as “microsoftscanreg.exe”:


It then registers this file in the system directory, ensuring that the worm will be launched each time Windows is rebooted on the victim machine:

"Microsoft Scanreg" = "%Windir%microsoftscanreg.exe" 

Propagation via P2P

The worm checks to see if Kazaa is installed on the victim machine, and creates the following folder:

%Windir%scanregfilekazaaMy Shared Folder

The worm then copies itself to this folder under the following names:

The worm modifies the configuration of Kazaa in the system registry so the resources which are shared by default will include the folder created by the worm:

"DownloadDir" = "%Windir%scanregfilekazaaMy Shared Folder"

This means that other Kazaa users will be able to access these files.
