Fuzzing is one of the most effective ways to find elusive software vulnerabilities. Despite years of research, general purpose fuzzers such as AFL++ and Libfuzzer struggle to mutate complex data structures effectively, preventing them from exploring deep functionality. Grammar fuzzing, an alternative fuzzing strategy is much more effective but complex to setup and run. Autarkie abstracts away all complexity and and surpasses all other grammar fuzzers in performance while offering novel features.
