Description

This is a virus detection. Viruses are programs that self-replicate recursively, meaning that infected systems spread the virus to other systems, which then propagate the virus further. While many viruses contain a destructive payload, it's quite common for viruses to do nothing more than spread from one system to another.

Indication of Infection

Presence of the following files in the WINDOWS directory:
  • Desktop-shooting.exe
  • Hello-Kitty.exe
  • BigMac.exe
  • Cheese-Burger.exe
  • Blaargh.exe
Presence of the files mentioned in the C:\Windows\Media folder.

Methods of Infection

This worm attempts to use the KaZaa file-sharing network and MSN Messenger instant messaging network to spread. The worm cannot propagate on it's own without either of these programs installed on the local system. It does not contain any other payload other than to propagate.

Aliases

I-Worm.Win32.Supova.45056 (Hauri), Trojan.Worm.P2p.Surnova.E (Mks), W32/Supova.C (Panda), Win32.HLLW.Supernova.45056 (DrWeb), Win32.Kitty.c (ESafe), Win32.Supova.E (VET), Worm.P2P.Surnova.e (AVP), WORM_SURNOVA.B (Trend)
   

Virus Characteristics

This is a minor variant of W32/Supova.d.worm, and is generically identified as W32/Supova.Worm with current engine and definitions.

This worm is designed to propagate through the KaZaa peer-to-peer file-sharing network and MSN Messenger. It attempts to lure KaZaa users into downloading and running itself by posing as software titles that users may find enticing.

Wars based on fairytales?

    This worm contains instructions to use PING as a denial of service attack against three Internet domains:

    • www.beliefnet.com
    • www.christianity.com
    • www.islamicity.com

    • Hehe, check this out :-)
    • Funny, check it out
    • LOL!! See this :D
    • LOL!! Check this out :)
    • Hehe, this is fun :-)
