Angr Backend
Install
PyPI
angr and the OFRAK components that use it can be installed with:
pip install ofrak_angr
An OFRAK container with the angr backend can be built with:
python3 build_image.py --config ofrak-angr.yml --base --finish
Usage
To use angr, you need to discover the components at setup-time with:
ofrak = OFRAK(logging.INFO)
ofrak.injector.discover(ofrak_angr)
ofrak.injector.discover(ofrak_capstone)
Note that the angr backend is designed to be used in conjunction with the Capstone backend, which implements BasicBlockUnpacker.
Warning
You can only use one of these analysis backends at a time (angr OR Binary Ninja OR Ghidra)
Angr auto-analysis
Using angr auto-analysis is transparent after the components are discovered, you don't have to do anything!
