HasteFuzz: Full-Speed Fuzzing

Abstract

Fuzzing throughput is an important factor affecting the overall fuzzing results. HasteFuzz presents an input filtering mechanism to improve fuzzing throughput. During fuzzing, HasteFuzz filters out inputs whose execution traces are encountered before and only conducts further analysis (bug and new coverage checking) on inputs with new execution traces. In this way, HasteFuzz enables the fuzzer to test and analyze more diverse inputs and improve fuzzing throughput.
