QueFuzz - libnetfilterqueue based network fuzzer

QueFuzz is a small fuzzer that uses libnetfilter_queue to take in packets from iptables. It's fuzzing engine either randomly fuzzes binary or ASCII protocols or uses a basic fuzzing template to search and replace packet data. QueFuzz has a very short learning curve, unlike many other fuzzing frameworks. It may not be as powerful but you can have it up and running in under a minute.

Unlike other fuzzers QueFuzz is not focused on data generation. It relies on a valid application to generate the data and instead just mutates the network traffic inline and passes it on.
