Overview

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.

This is a floppy and KaZaa peer-to-peer file sharing network worm. It propagates by altering KaZaa default local content shares, enabling file-sharing, and copying itself to those shares. When run, it sets the default KaZaa local content folders as C:\ and C:\My Documents. It then copies itself to the following files:

  • c:\Fire.mp3.EXe
  • c:\How to make viruses.txt.EXe
  • c:\HULK.mpeg.EXe
  • c:\HULK.mpg.EXe
  • c:\Pentium 5.doc.EXe
  • c:\Pentium 5.rtf.EXe
  • c:\Playboy 9.mpeg.EXe
  • c:\Reign of Fire.mpeg.EXe
  • c:\ReignoFire.mp3.EXe
  • c:\Setup.exe.EXe
  • c:\TheTuxedo.mpeg.EXe
  • c:\Zephyr Song.mp3.EXe
It also copies itself to the A:\ drive as The Incredible Hulk.EXe.

The following registry key is modified to load the worm whenever .EXE files are run:

  • HKEY_CLASSES_ROOT\exefile\shell\open\
    command "(Default)" = %worm path% "%1" %*
Each time this occurs, a minimized form is displayed.

When that form is maximized the following Window is observed
