More Information
W32/Surnova-A is a worm that spreads using the KaZaA network software installation and the MSN instant messenger utility.
The worm will initially copy itself to the Windows folder with one of the following filenames:
Alles-ist-vorbei.exe
Desktop-shooting.exe
Hello-Kitty.exe
BigMac.exe
Cheese-Burger.exe
Blaargh.exe
The value HKLM\Software\Microsoft\Windows\CurrentVersion\Run\Supernova is added to the registry and points to the new copy of the worm so that the worm is run when Windows starts up.
The following fake error message will be displayed by the worm when it is first executed:
"Application attempted to read memory at 0xFFFFFFFFh Terminating application".
The worm queries the registry entry HKLM\Software\KaZaA\LocalContent for a folder that is shared across the KaZaA network. If a value is not found then the folder C:\<Windows>\Media is used. Then thirty eight copies of the worm are created in this folder with the filenames:
