Fusil uses small “agents” which exchange messages to launch actions. e.g. MangleFile injects errors into [...]

Seen as though untidy was mentioned again fairly recent, it sparked my memory that I have a fairly old draft regarding untidy the XML Fuzzer.
Fuzzing is definitely becoming an important part of Pen Testing and especially application security – we’ve published about quite a few and I’m sure there are more in development.

Anyway, back [...]
