So I was given the chance to speak at the monthly Ruxmon security lectures here in Melbourne. While many people were off at Blackhat and Defcon this month, the room we were in was packed. In fact, I would say about 45-50 or so humans showed up! It was a blast, and I feel my communication went well. The talk I gave was on PDFs, PostScript, the security concerns of these data formats/languages, and the PDFResurrect. The slides I have posted here.
