boofuzz vs Netzob

boofuzz is a network protocol fuzzing framework and a successor to Sulley. It installs as a Python library for building fuzzer scripts, using `pip install boofuzz`, and requires Python 3.9 or later. Its workflow generates data, detects failures, resets targets after failures, and records test data. It supports varied communications, including serial, Ethernet and IP-layer traffic, UDP broadcast, TCP, UDP, SSL, and raw sockets. Run logs are saved in a SQLite database in the boofuzz-results directory, saved runs can be reopened in a web interface with `boo open`, and results can be exported as CSV. A process monitor can detect crashes and restart applications on Windows or Linux, but must run on the target machine. The optional network monitor requires Pcapy and Impacket, which are not installed automatically. Public FTP and HTTP protocol libraries are documented, though their implementations do not provide full protocol coverage. The project describes extensibility for instrumentation and failure detection. It uses the GPL-2.0 license; usage questions are directed to Stack Overflow, while bugs and suggestions can go to GitHub issues or pull requests.

Netzob is a free, GPLv3-licensed open-source tool for reverse engineering, traffic generation, and fuzzing of communication protocols. It infers message formats and protocol state machines through passive and active processes. Vocabulary inference learns formats from supplied traces, while grammar inference supports semi-automatic state-machine learning. With those models, its simulator can act as a client, server, or both to generate traffic. The fuzzing module creates optimized test cases by mutation or generation. Inputs can include live network traffic, PCAP captures, IPC, text and binary files, and API flows through supported formats. Exports include XML, human-readable output, and Peach fuzzer formats, with custom exporters possible. Netzob runs locally on Linux and Windows and supports Python 3. It targets network protocols, structured files, text protocols, drivers, devices, and other listed target types. Version 0.4.1 is listed as the latest stable release, with packages dated February 2, 2013.
