bap - Binary Analysis Platform

  •    OCaml

The Carnegie Mellon University Binary Analysis Platform (CMU BAP) is a reverse engineering and program analysis platform that works with binary code and doesn't require the source code. BAP supports multiple architectures: ARM, x86, x86-64, PowerPC, and MIPS. BAP disassembles and lifts binary code into the RISC-like BAP Instruction Language (BIL). Program analysis is performed using the BIL representation and is architecture independent in a sense that it will work equally well for all supported architectures. The platform comes with a set of tools, libraries, and plugins. The documentation and tutorial are also available. The main purpose of BAP is to provide a toolkit for implementing automated program analysis. BAP is written in OCaml and it is the preferred language to write analysis, we have bindings to C, Python and Rust. The Primus Framework also provide a Lisp-like DSL for writing program analysis tools. BAP is developed in CMU, Cylab and is sponsored by various grants from the United States Department of Defense, Siemens AG, and the Korea government, see sponsors for more information.

bytecode_simplifier - A generic deobfuscator for PjOrion obfuscated python scripts

  •    Python

PjOrion obfuscates the original file and introduces several wrapper layers on top of it. The purpose of these layers is simply to (sort of) decrypt the next inner layer and execute it via an EXEC_STMT instruction. Hence you CANNOT use this tool as-is on an obfuscated file. First, you would need to remove the wrapper layers and get hold of the actual obfuscated code object. Then you can marshal the obfuscated code to disk and run this tool on it which should hopefully give you back the deobfuscated code. Refer to this blog post for details.
