PyREBox - Python scriptable Reverse Engineering sandbox

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.



PyREBox allows to dynamically load scripts that can register callback functions that are called when certain events occur, like instructions executed, memory read/written, processes created/destroyed, and so on.
Given that PyREBox is integrated with Volatility, it will let you take advantage of all the volatility plugins for memory forensics in your python scripts. Many of the most famous reverse engineering tools are implemented in Python or at least have Python bindings. Our approach allows to integrate any of these tools into a script.
Finally, given that python callbacks can introduce a performance penalty on frequent events such as instructions executed, it is also possible to create triggersTriggers are native-code plug-in’s (developed in C/C++) that can be inserted dynamically at run-time on any event just before the Python callback is executed. This allows to limit the number of events that hit the python code, as well as to precompute values in native code.
