Technical Details


Variant:SSIWG.A@mm

When VBS/SSIWG.A@mm is executed, it copies itself to the Windows System directory as "Y072QWV.VBS". This file is also set to be executed in each system startup via following registry key:

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

Next the worm copies itself to the root of each network drive, and sends itself to all recipients in all address books using Outlook. Messages that VBS/SSIWG.A sends have the following characterstics:

  Subject:    I'am missing U     Body:       Could u remember me ?     Attachment: Y072QWV.VBS  

Note: The name of the attachment can be other that "Y072QWV.VBS".The worm uses a counter in the registry, so the mass mailing will happen only every 20th run.
