Overview
This project is a Python, mutation based file fuzzer that uses PyDBG to monitor for signals of interest.
Architecture
The architecture for the fuzzer follows the client/server model. Any number of clients can connect to the server, allowing for
very fast execution. I personally connect about a dozen clients per box to the server, your specs may vary. The communication between
client and server basically follows:
1. Client connects to server, gets a copy of the original file, possible mutations, and path to the target excutable
2. Client enters loop. Ask the server for next mutation, server responds with offset into the file and mutation index
3. Client creates the mutated file (less network communication), executes it with PyDBG.
4. *If* a crash occurs, client send crash information to the server, and the server creates a local copy of the file
During execution the server gives you the ability to show : clients, mutation statistics, crashes. The server can also
be paused, causing clients to sleep for a little bit before checking back.
