butterfly

Description

This crate brings stateful fuzzing capabilities to LibAFL via

Packet-based Inputs: Inputs that are vectors of packets and can be loaded from pcap files
Packet-based Mutations: Mutators that can be applied to selected packets only (havoc and protocol-aware mutations like packet insertion, deletion and reordering)
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

butterfly uses rust 2021 edition, so execute

rustup toolchain install nightly

and in your Cargo.toml insert

[dependencies]
butterfly = { version = "0.2.2", package = "butterfly-fuzz" }
