butterfly
This crate brings stateful fuzzing capabilities to LibAFL via 1. Packet-based Inputs: Inputs that are vectors of packets and can be loaded from pcap files 2. Packet-based Mutations: Mutators that can be applied to selected packets only (havoc and protocol-aware mutations like packet insertion, deletion and reordering) 3. State-Graph Inference: Observe which states your target goes through as it processes the individual packets and identify when it enters a new state or makes a new state transition
