Technical Details


When run, the worm checks files

winexec32.exe
adaware32.exe
VB6.EXE
iexplore.exe
 

If these files are not found, it drops file "cz.exe" and executes it. This file is a variant of Rbot which is detected generically by FSAV.Brobia.C can also disable mouse right button.

MSN spreading

The worm copies itself in C-directory using one of the following filenames:

LOL.scr
Webcam.pif
hahahaha.pif
me_2005.pif
sister.pif

 

Then it attempts to send this file using MSN messenger to all active MSN contacts. The MSN messenger window has to be open on the infected computer's desktop for this to be successful.
