Abstract interpretation using lattices to analyse the possible sign of a variable at any point in a program.
A simple plugin demonstrating the binja headless api for python. Finds memcpy's and corresponding src/dst information. The plugin can be modified to find argument information for other function calls.
A plugin template to walk the binja CFG using the depth-first search algorithm (aka path sensitive, one path traversed at a time)
Clone this repo
Place walk_via_dfs.py and signed_analysis.py into your Binja Plugin folder, the usual location is:
/Users/<user>/Library/Application Support/Binary Ninja/plugins
Install binaryninja headless python API using this script
Open a binary in Binary Ninja, right click on a function, and run either the signed analysis script or the dfs script.
To run the memcpy script, cd into the directory it is in and run as a normal python script with the full path to you binary as the 2nd argument. Example:
python binja_memcpy.py /bin/bash
