This tutorial shows the main features of Netzob regarding the inference of the message format and grammar of a simple toy protocol.
The goal of this tutorial is to present the usage of each main component of Netzob (inference of message format, construction of the state machine and generation of traffic) through an undocumented protocol.
This tutorial shows how to take advantage of the Peach exporter plugin provided in Netzob to automatically generate Peach pit configuration files, thus allowing to do smart fuzzing on undocumented protocols.
This tutorial shows how to leverage Netzob' format message inference in order to automatically generate Wireshark dissectors for proprietary or undocumented protocols.
We provide here the complete scripts related to the article we have written in the MISC HS n°7, named 'Vivisection de protocoles avec Netzob'.

Dans cet article, nous présentons une méthodologie pour disséquer sur le vif, un protocole de communication. Promis, pas de copie d’écrans d’IDA ni d’OllyDbg, et à l’inverse pas de formule mathématique. Pour être précis, ici on dissèque des protocoles inconnus en Python avec « son Netzob et son couteau ».
In this paper, we present Netzob, an opensource tool which supports the expert in its operations of reverse engineering, evaluation and simulation of communication protocols.
Its main goals are to help security evaluators to assess the robustness of proprietary or unknown protocols implementation, simulate realistic communications to test third-party products (IDS, firewalls, etc.) or even create an open source implementation of a proprietary or unknown protocol.
Netzob supports the expert in a semi-automatic manner.
It includes the necessaries to passively learn the vocabulary of a protocol and to actively infer its grammar.
In addition, it integrates a stochastic and statefull model to represent any statefull communication protocol.
The definition of the model can be shared and loaded in a dedicated component of Netzob, its simulator.
Therefore, it becomes easy to simulate multiple actors (servers and clients) which communicate according to the inferred protocol, and to apply advanced fuzzing.
Introduce an extended version of a Mealy automata to model and simulate botnets communications.
