SAFIREFUZZ Experiments

This repository contains documentation, scripts and raw data for the artifact evaluation of the USENIX `23 paper "Forming Faster Firmware Fuzzers".

For more details regarding our work, have a look at the main repository:
https://github.com/pr0me/SAFIREFUZZ

This repository is structured as follows:

• Firmware:
  • The firmware used in the evaluation of this paper
• Fuzzing:
  • setup and build scripts / documentation for the frameworks we evaluated our approach against
  • includes firmware binaries and initial fuzzing seeds
• Coverage Collection
  • setup used to re-run fuzzing queues to collect detailed coverage information
• Case Studies
  • information regarding the two novel targets we investigated
• Eval Data
  • raw data collected during our evaluation, matching the results reported in the paper

Overall, it is possible to either first run fuzzing for all targets and collect coverage by replaying the queues afterwards, or fuzz, collect, fuzz, collect...
But there are a couple of things to pay attention to:

1. Always make sure to make backups of your fuzzing queues. Especially for safirefuzz_target.py, output directories might get re-used.
2. The cov collection script for SAFIREFUZZ and hal-fuzz (eval_bbs_halucinator.py) replays one target at a time and takes input and output paths as arguments, so it should be straight-forward to parallelize things.
   If you wish, you can also adapt our scripts to this end.
3. If you switch between fuzzing and coverage collection, remember to apply and revert the different sets of HALucinator patches for fuzzing and replaying or make a local copy of the hal-fuzz directory for both use cases.

Using coverage collected on your own or our original data, you can then proceed to replicate our results with our statistics and plotting scripts.
