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.

Characteristics

This threat is detected as VBS/VBSWG.gen@MM with the 4205 dats. This worm arrives in an email message containing the following information:

Subject: Shakira's Pictures
Body: Hi :

Attachment: ShakiraPics.jpg.vbs

When the attachment is run, the script mails itself to all addresses found in the Outlook Address Book and the file c:\mirc\script.ini is overwritten with instructions to send itself to IRC users who join the same channel as the infected user. A message box is displayed:

The script copies itself to the WINDOWS directory and attempts to overwrite .VBS and .VBE files. After the virus runs, it creates the following registry key values:

• HKEY_CURRENT_USER\Software\ShakiraPics\mailed=1
• HKEY_CURRENT_USER\Software\ShakiraPics\Mirqued=1
• HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\
  Run\Registry=wscript.exe C:\WINDOWS\ShakiraPics.jpg.vbs %
