ROPMEMU

ROPMEMU is a framework to analyze, dissect and decompile complex code-reuse attacks. It adopts a set of different techniques to analyze ROP chains and reconstruct their equivalent code in a form that can be analyzed by traditional reverse engineering tools. In particular, it is based on memory forensics (as its input is a physical memory dump), code emulation (to faithfully rebuild the original ROP chain), multi-path execution (to extract the ROP chain payload), CFG recovery (to rebuild the original control flow), and a number of compiler transformations (to simplify the final instructions of the ROP chain).

Specifically, the memory forensics part is based on Volatility [1] plugins. The emulation and the multi-path part is implemented through the Unicorn emulator [2].

ROPMEMU has been published at AsiaCCS 2016 [3] and the paper can be found here [4].

ROPMEMU documentation can be found in the Wiki pages.

Happy hacking!
