GnuCitizen just published an interesting bit of news. PDF files, the lingua franca of online documents, have an exploit that can offer up control of Windows “completely, invisibly, and unwillingly.” All you have to do is open the file. From the site:

My advise for you is not to open any PDF files (locally or remotely). Other PDF viewers might be vulnerable too. The issues was verified on Windows XP SP2 with the latest Adobe Reader 8.1, although previous versions are also affected.

More news as we find it, but this looks purdy serious. Good thing I’m running 3.11.
