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.



Unicorn Emulator 1.0.1 released

Nguyen Anh Quynh announced the 1.0.1 release of the Unicorn CPU Emulator.

[unicorn-engine] Unicorn Emulator v1.0.1 is out!
We are excited to announce version 1.0.1 for Unicorn CPU Emulator framework! This is a stable release, in which we fixed some issues in the core, added some features on Arm, Arm64, Mips & X86. […]





grap: define and match graph patterns within binaries:
grap takes patterns and binary files, uses a Casptone-based disassembler to obtain the control flow graphs from the binaries, then matches the patterns against them. Patterns are user-defined graphs with instruction conditions (“opcode is xor and arg1 is eax”) and repetition conditions (3 identical instructions, basic blocks…). grap is both available as a standalone tool with a disassembler and as an IDA plugin which takes advantage of the disassembly done by IDA and the reverser.




CaptainHook is hooking framwork for x86/x64 arch, it’s based on capstone disassembler engine. CaptainHook equipped with smart engine (TO FINISH). CaptainHook is easy to using, and very freandly. the hook engine is much like MS Detours, so why to choose it?

* its support x64 (Detours x64 is commerical – $10,000~)
* CaptainHook will know where to locate your hook in real time, its analyze the code, and find if small API redirection (Wow64 hook on kernelbase for example, or on protector like VMP or Themida) was occurred
* in the next release, CaptainHook will contain an engine for jmp/conditional jmp repair – if your hook corrupt sensitive code
* in the next release, CaptainHook will contain more hook type, like PageGuard hooking etc.
