Dynamic Binary Analysis and Obfuscated Codes

Abstract

At this presentation we will talk about how a DBA (Dynamic Binary Analysis) may help a reverse engineer to reverse obfuscated code. We will first introduce some basic obfuscation techniques and then expose how it’s possible to break some stuffs (using our open-source DBA framework - Triton) like detect opaque predicates, reconstruct CFG, find the original algorithm, isolate sensible data and many more… Then, we will conclude with a demo and few words about our future work.
