Technical Details



This is the first worm to use Adobe Acrobat PDF format as a platform. However, it only works under the full 'developer' version of Acrobat. The common Acrobat Reader program is not affected by this worm.

The worm operates as a VBS script embedded within a PDF file. The worm show a simple 'peach' game on screen, with a large collage picture of peoples behinds and this text:

You have one minute to find the peach!
[ ]
Double click the icon to show the solution

Note: Full version (not Acrobat Reader) is needed to show the solution

When the user doubleclicks on the icon shown, the worm collects e-mail addresses from Microsoft Outlook and sends itself further via e-mail.

As of 9th August 2001, this worm is not a real-world threat.
