LLVM-powered devirtualization
Virtualization is a powerful technique for code obfuscation, and reversing it can be challenging. In this post, we cover the work done during an internship on developing an automated devirtualization ...

Recently finished an internship at Thales where I worked on binary deobfuscation using LLVM.
Here's a brief summary:

I spent all day writing an optimization that made my code 5% faster and 5% more accurate. I was quite disappointed.
In 15 min, I made another optimization. My code is now 10x faster and 100x less accurate.

I'm working on graph visualisation, and so far it's going spectacularly poorly.
Shout-out to the edge E->H for having the wonkiest path.

Found this insanely helpful post on the state of the art in decompilation. Specifically, it dives into the "structuring problem" : trying to identify "if"s, "while"s and other patterns in a CFG while minimizing the use of "goto".
