Technical Details


Variant:Nowobbler.A

The worm spreads in Outlook messages with:

Subject:

Fw:important
 Body: Thought you might be interested in this message,
 read the attachment for more information
 Attachment: WOBBLER.TXT.VBEor WOBBLER.TXT.JSE

With 1/5 probability the worm sends message in Spanish, without any attachment:

Subject:

Alma
 Body: No alucines que te amo,
 cuando en realidad es solo
 mi corazon quiin lo hace.
 Porque como ya sabras,
 mi corazon no manda en mi vida,
 si asi lo hiciera
 mi alma estaria perdida.

When executed, the worm shows the Wobbler hoax text.

Then the worm creates a temporary file with a random name and the extension ".wsc" to the Windows System directory. The file is executed and the worm mass mails itself. This file is deleted after the worm has mass mailed itself.

The worm also copies itself to the root of each network drive.
