Proof of Concept for example 1 (backdoored1.pdf) opened with Adobe Reader 7.0.8 (i.e. no browser plug-in used) issued a Security Warning dialog box: "The document is trying to conenct to the site: http://www.google.com/owned.html If you trust the site click "Allow", otherwise click "Block"." Option Remember my action is in use as well. When clicking "Allow" this Google page was opened in MSIE (in fact FF is my default browser, however). Am I missing something related to differences between Reader plug-in and Reader application? - Juha-MattiDavid Kierznowski <david.kierznowski () gmail com> wrote:
Recently, there has been alot of hype involving backdooring various web technologies. pdp (arcitect) has done alot of work centered around this area. I saw Jeremiah Grossman mention PDF's being "BAD", however, I was unable to easily locate any practical reasons as to why. I decided to investigate this a little further. This article discusses two possible backdoor techniques for Adobe Acrabat Reader and Professional. It includes proof of concept code and backdoored PDF documents.
