VBS/VBSWG-AQ

Name: VBS/VBSWG-AQ
Type: Visual Basic Script worm
Date: 5 June 2002

Sophos has received several reports of this worm from the wild.

Description:

VBS/VBSWG-AQ is an email worm. The worm spreads using an email
with the following characteristics:

Subject line: Shakira's Pics
Message text:
Hi :
i have sent the photos via attachment
have funn...
Attached file: ShakiraPics.jpg.vbs

When the attachment is run it will copy itself into the Windows
folder and add the registry entry

HKLM\Software\Microsoft\Windows\CurrentVersion\Run\Registry

to ensure that the worm is run each time Windows is started. It
will then attempt to email itself to all addresses listed in the
Microsoft Outlook address book. If the worm detects that mIRC is
installed it will create the file script.ini in the mIRC folder.
This file is detected by Sophos Anti-Virus as mIRC/Simp-Fam.

VBS/VBSWG-AQ will also create the registry entries

HKCU\Software\ShakiraPics\mailed
and
HKCU\Software\ShakiraPics\mirqued

after it has attempted to spread by email and IRC.

The worm will then search all local and network drives for files
with VBE or VBS extensions and overwrite them with a copy of
itself.

Finally the worm will display the message
"You have been infected by the ShakiraPics Worm".
