A tool to find and inspect File Stream Oriented Programming (FSOP) code paths. Heavily inspired by KyleBot's angry-FSROP repository.

To find the conditions leading to an FSOP code path more easily and to learn more about angr. Read my blog post on FSOP for more details.

First, install angr (use requirements.txt if you want to use the outputs I generated). Then, generate some outputs using the angry-fsrop.py script, which takes a couple of hours. Alternatively, use the already generated outputs from GLIBC 2.35. Finally, use examine_paths.py to inspect a specific output.

python examine_paths.py --file outputs/_IO_file_finish.pickle --mode best
