Technical Details




Variant:Scary.A

The worm arrives in email messages with the following characteristics:

  Subject: The Secret of Life
 Body:
 Attachment: Secret.htm

When the attachment is opened, the worm executes. First the worm resizes the browser window to cover the full screen.

Then it sends itself to all recipients in each Outlook address book and copies itself to the Windows startup directory. The worm modifies the attributes of the copied file ("Secret.htm") so that the file will be marked as a hidden and read-only.

Next the worm will show message boxes claiming that it deletes all directories of all drives. Instead of deletion, the worm creates twenty files with "tmp" extension to the root of each drive.

Finally it shows the following message boxes:

  So how did you feel being dishonored in public?

and

  So did you learn your lesson?

If the user selects the "Yes" button, the file from the startup directory will be deleted and several message boxes will be shown.

If the user selects the "No" button, the file in the startup directory will not be deleted causing that the worm will be executed again when the system is restarted.
