macholibre

Description

macholibre is a Mach-O and Universal binary parser. It extracts information such as architectures, load commands, dynamic libraries, symbols, function imports, and tons more. Then it packs all of that information into JSON for ease of analysis and integration.

Python 2

With Python 2 in its sunset years, macholibre has moved on to Python 3. However, for those of you that are stuck on Python 2, see the python2 branch. No promises on long-term support, but the code differences right now are minimal and should be fairly easy to maintain.

Dependencies

This project requires Python 3.4+ to run, due to API changes in plistlib.

I tried to make this tool with as little external dependencies as possible, and I think I did pretty well on that front. The only module I import is for parsing CMS signatures. I've configured setup.py to automatically install it with the module, but you can also install it seperately with pip or manually from github.

How To

Installation

I recommend using pip to install macholibre.

pip3 install git+https://github.com/aaronst/macholibre.git

Usage

As a Module

from macholibre import parse

# mach-o file path
path = '/home/aaron/my_macho'

# return dict
data = parse(path)

# write json to file
out_file = open('/home/aaron/macholibre_output.json', 'w')
parse(path, out=out_file)

As a Script

usage: macholibre [-h] [-c] [-o OUTPUT] input [input ...]
