Twinner is a deobfuscation framework. It inspects executable binaries, instruments them using the PIN Intel framework for binary instrumentation, analyzes executed assembly instructions through a concolic execution, models the behavior of the program as a set of symbolic expressions and constraints, and recodes it as twincode, a compilable C program with simplified logic.
The framework allows automatic deobfuscation of the virtualization obfuscated binaries on 64bit Linux and 32bit Windows. Twinner is developed by Behnam Momeni and its source code is released under GPLv3. It is available on GitHub. Twinner is a work in progress, so if you are not familiar with the context, you should wait for the v1.0.0 release. Otherwise, have happy hacking :) There is no regular release schedule and every version is released when it is ready.
