Bad pdf! BAD!

You look at pdfs, you should be aware:

The flaw, first revealed at a hacker conference in Germany over the holidays, exists in a plug-in that enables Acrobat users to view PDF files within Web browsers.

By manipulating the Web links to those documents, hackers and online thieves are able to commandeer the Acrobat software and run malicious code when users attempt to open the files, according to Ken Dunham, director of the rapid response team at VeriSign’s iDefense Intelligence.
