Block Possible Attacks in Adobe Acrobat and Adobe Reader

Didier Stevens, has developed a proof-of-concept PDF file that launches an embedded executable. According to Stevens, PDF viewers like Adobe Reader and Foxit Software's Foxit Reader do not allow embedded executables to be extracted and run. In his proof-of-concept, however, he was able to execute the embedded executable using a launch action triggered when his PDF file is opened.

Fix for "This document contains JavaScripts" message

If you've disabled JavaScript in Adobe Acrobat 7.x or Reader 7.x, you'll probably get an annoying message every time you exit the program, stating that, "This document contains JavaScripts," although the document did not contain any JavaScript code.

Acrobat JavaScripts message

Here are the steps to disable that message in Windows XP, short of enabling JavaScript.

  1. Find the location of Acrobat's "JavaScripts" directory.
    On Windows XP, this is C:\Documents and Settings\<username>\Application Data\Adobe\Acrobat\7.0\JavaScripts\.
    * Where <username> is the account that you've logged into Windows with.
    ** Where C: is the hard disc drive or partition that Windows XP is installed on.

  2. Rename the JavaScripts directory to JavaScripts.old.
  3. Create an empty text file named JavaScripts, using Notepad, in the same directory that the JavaScripts directory was in.
    On Windows XP, this is C:\Documents and Settings\<username>\Application Data\Adobe\Acrobat\7.0\.

Note: It appears that Adobe has corrected the above issue with the v7.0.5 update.
