bytecode_simplifier - A generic deobfuscator for PjOrion obfuscated python scripts

  •        14

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.

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.

barf-project - BARF : A multiplatform open source Binary Analysis and Reverse engineering Framework

  •    Python

The analysis of binary code is a crucial activity in many areas of the computer sciences and software engineering disciplines ranging from software security and program analysis to reverse engineering. Manual binary analysis is a difficult and time-consuming task and there are software tools that seek to automate or assist human analysts. However, most of these tools have several technical and commercial restrictions that limit access and use by a large portion of the academic and practitioner communities. BARF is an open source binary analysis framework that aims to support a wide range of binary code analysis tasks that are common in the information security discipline. It is a scriptable platform that supports instruction lifting from multiple architectures, binary translation to an intermediate representation, an extensible framework for code analysis plugins and interoperation with external tools such as debuggers, SMT solvers and instrumentation tools. The framework is designed primarily for human-assisted analysis but it can be fully automated. All packages were tested on Ubuntu 16.04 (x86_64).

pyrebox - Python scriptable Reverse Engineering Sandbox, a Virtual Machine instrumentation and inspection framework based on QEMU

  •    C

PyREBox is a Python scriptable Reverse Engineering sandbox. It is based on QEMU, and its goal is to aid reverse engineering by providing dynamic analysis and debugging capabilities from a different perspective. PyREBox allows to inspect a running QEMU VM, modify its memory or registers, and to instrument its execution, by creating simple scripts in python to automate any kind of analysis. QEMU (when working as a whole-system-emulator) emulates a complete system (CPU, memory, devices...). By using VMI techniques, it does not require to perform any modification into the guest operating system, as it transparently retrieves information from its memory at run-time. Several academic projects such as DECAF, PANDA, S2E, or AVATAR, have previously leveraged QEMU based instrumentation to overcome reverse engineering tasks. These projects allow to write plugins in C/C++, and implement several advanced features such as dynamic taint analysis, symbolic execution, or even record and replay of execution traces. With PyREBox, we aim to apply this technology focusing on keeping the design simple, and on the usability of the system for threat analysts.

simplify - Generic Android Deobfuscator

  •    Java

Simplify virtually executes an app to understand its behavior and then tries to optimize the code so that it behaves identically but is easier for a human to understand. Each optimization type is simple and generic, so it doesn't matter what the specific type of obfuscation is used. The code on the left is a decompilation of an obfuscated app, and the code on the right has been deobfuscated.

decomp - Components of a decompilation pipeline.

  •    Go

The aim of this project is to implement a decompilation pipeline composed of independent components interacting through well-defined interfaces, as further described in the design documents of the project. From a high-level perspective, the components of the decompilation pipeline are conceptually grouped into three modules. Firstly, the front-end translates a source language (e.g. x86 assembly) into LLVM IR; a platform-independent low-level intermediate representation. Secondly, the middle-end structures the LLVM IR by identifying high-level control flow primitives (e.g. pre-test loops, 2-way conditionals). Lastly, the back-end translates the structured LLVM IR into a high-level target programming language (e.g. Go).

panda - Platform for Architecture-Neutral Dynamic Analysis

  •    C

PANDA is an open-source Platform for Architecture-Neutral Dynamic Analysis. It is built upon the QEMU whole system emulator, and so analyses have access to all code executing in the guest and all data. PANDA adds the ability to record and replay executions, enabling iterative, deep, whole system analyses. Further, the replay log files are compact and shareable, allowing for repeatable experiments. A nine billion instruction boot of FreeBSD, e.g., is represented by only a few hundred MB. PANDA leverages QEMU's support of thirteen different CPU architectures to make analyses of those diverse instruction sets possible within the LLVM IR. In this way, PANDA can have a single dynamic taint analysis, for example, that precisely supports many CPUs. PANDA analyses are written in a simple plugin architecture which includes a mechanism to share functionality between plugins, increasing analysis code re-use and simplifying complex analysis development. It is currently being developed in collaboration with MIT Lincoln Laboratory, NYU, and Northeastern University.

Malware - Course materials for Malware Analysis by RPISEC

  •    

This repository contains the materials as developed and used by RPISEC to teach Malware Analysis at Rensselaer Polytechnic Institute in Fall 2015. This was a university course developed and run soley by students, primarily using the Practical Malware Analysis book by Michael Sikorski and Andrew Honig, to teach skills in reverse engineering, malicious behaviour, malware, and anti-analysis techniques. The Practical Malware Analysis (PMA) book is where many RPISEC members and alumn started. The book reads very well, is full of information, and the lab walkthroughs in the back are invaluable. We didn't want to re-invent the wheel so we structured most of the class around the book. Students were expected to have read the relevant PMA book chapters before class, allowing us to spend much more class time demonstrating skills and techniques and walking through hands-on examples with the students.

The tool performs static code analysis which means that you don't have to run your application in order to use it.Your application needs to be compatible with the Angular's AoT compiler (i.e. you should be able to compile it with ngc).

openreil - Open source library that implements translator and tools for REIL (Reverse Engineering Intermediate Language)

  •    C

OpenREIL is open source library that implements translator and tools for REIL (Reverse Engineering Intermediate Language). However, after Zynamics was acquired by Google they abandoned BinNavi, so, I decided to develop my own implementation of REIL. I made it relatively small and portable in comparison with original, the translator itself is just a single library written in C++, it can be statically linked with any program for static or dynamic code analysis. The higher level API of OpenREIL is written in Python, so, it can be easily utilized in plugins and scripts for your favourite reverse engineering tool (almost all modern debuggers and disassemblers has Python bindings).
