This blog is far from dead! I have been involved in some very interesting research these past few months. Yan Ivnitskiy and I presented at the BlackHat conference in Las Vegas this August. The title of our talk was Attacking Client Side JIT Compilers. We researched everything from incorrect JIT code emission to reusing predictable JIT code sequences.
We have published our slides and our research paper on the Matasano research website. You can find it all here. Feel free to email either Yan or myself if you have any questions about the content.
