I think it depends on the context. Example 1 (backdoored1.pdf) : On Ubuntu Linux with Adobe Reader 7.0.1 opens the web page on mozilla-firefox whitout warning. On Windows XP sp2 with Adobe Reader 7.0.8 sends a warning about open the url. Example 2 (backdoored2.pdf) : On Ubuntu Linux and windows XP sp2 does nothing apparently. it, could be possible to make multi-target attacks :) but other viewers like evince or xpdf don't have any effect :( Regards!

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-Matti David 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.
