Python interface to dynamic binary instrumentaton framework PIN

I work in analyzing binary files, using Python. I have been using debuggers to do a dynamic analysis (i.e running the application and using breakpoints to get runtime execution). however, results can be improved if i can use some binary instrumentation fremework like PIN. The PIN is developed in C++ and provided as closed source (only dlls). We write something called PinTools do describe where and what we want to intercepts. I want to port PIN functionality into Python so that i continue using Python. I am aware of "ctypes" and boost-python.

My problem is: in order to use PIN, we write a pintool and run our bibnary executable with Pin and pintool (it is like开发者_如何转开发 running application with JIT). Now, I have no idea if I can use ctypes etc. to import PIN functions and use this python code for dynamically analyzing the binary. Can you please provide some suggestions or guidelines on how to proceed with this task.

So, in nut-n-shell, I want to create a Python interface (wrapper) to PIN framework.

Check out the ProcessTap project. Appears to implement exactly what you are looking for: http://code.google.com/p/processtap/

I was thinking about this recently, while I haven't looked into it, I would approach the problem like this: write a pintool that, upon initialization, starts an embedded python interpreter and imports a python module. I'd look at using SWIG to generate bindings for all the PIN api calls you want to use. Then the pintool would call a hardcoded function in the imported python module that would issue calls to the api to register more functions and do whatever you want to do.

I'm not sure how the callbacks would work, I don't know enough about SWIG. Also, this may fail if the program you're trying to instrument itself uses Python. But that's how I'd try to solve this problem to start out.
