...The "Security Companies" might say so to sell more of their products. But no, binary obfuscation won't magically fix all your exploits and bugs, (If not introducing more). Designing an Obfuscator is hard, and keeping the source open definitely leaks the pattern to crackers which could potentially make the crackers' life easier if they have the right skillset. While every reasonable attempt has been made in Hikari to reduce such patterns from appearing, however, with overkill weapons like symbolic execution, binary obfuscation can still be defeated much easier, even so-called VM-based obfuscation. ...

The Miasm intermediate representation is used for multiple task: emulation through its jitter engine, symbolic execution, DSE, program analysis, but the intermediate representation can be a bit hard to read. We will present in this article new tricks Miasm has learned in 2018. Among them, the SSA/Out-of-SSA transformation, expression propagation and high-level operators can be joined to “lift” Miasm IR to a more human-readable language. We use graphviz to illustrate some graphs. Its layout does not always totally conform with a reverse engineering “ideal view”, so please be tolerant of those odd graphs. ...
