Name : I-Worm.MaLoTeYa
Author : PetiK
Date : July 2nd - July 6th
Size : 12288 byte
Action: It copies itself to \WINDOWS\RUNW32.EXE and to \WINDOWS\SYSTEM\MSVA.EXE. It alters the
run= line and creates the VARegistered.htm file in the StartUp folder. This file send some
informations to petik@multimania.com and displays a fake message.
If the version of the platform is Windows 95/98, the file is a service process.
It infects all *.htm and *.html file while writing at the end a VB script. It checks after
if exist a internet connection and scans all *.htm* files in the "Temporary Internet Files"
to find some EMail addreses and send a copy of itself. The worms sends equally an email to
"petik@multimania.com" with the country of the user. When the user want to see the
system properties, the title of the window is changed by "PetiK always is with you :-)".
Greets to Benny, ZeMacroKiller98, Mandragore.
