New PDF Embedded Virus Circulating

Virus Circulating as a PDF Embedded Executable

Adobe’s “Launch” feature has been exploited to allow a virus to be inserted in to a PDF and downloaded to your computer. A new virus, which does just that, is currently circulating.

This version of the virus is being circulated as an attachment in PDF’s titled Royal_Mail_Delivery_Notice.pdf.

If you open a PDF, and are greeted with a dialogue box prompting you do download Royal_Mail_Delivery_Notice.pdf , or to “choose an extraction location”, be sure to cancel the action, close the dialogue box and delete the infected PDF.

FoxIt Readers need to take extra care, as FoxIt Reader does not currently give the user the dialogue box as outlined above, but rather begins automatically downloading the virus to your My Documents Folder.

Until a patch is released, Adobe suggests the following work around to help prevent infection:

In Adobe Reader and Acrobat, edit your preferences

  1. Edit
  2. Preferences
  3. Categories
  4. Trust Manager
  5. PDF File Attachments – clear or deselect the check box for “ Allow opening of non PDF file attachments with external applications.
