Last Friday I was at ReCon in Montreal to give a talk about obfuscated PDF malware. I got the idea for the talk during my work on PDF Dissector where I saw a lot of obfuscated PDF malware. The obfuscation I saw in the wild was mostly very limited and the malware authors did not seem to think things through to the very end. I took the opportunity to think a bit further about the whole topic of PDF malware obfuscation and a few of the result of these thoughts can be seen in the slides below.
