Research and Development

UDP protocol analysis is a python module which can be used in scripted analysis or interactively using ipython.

Some time ago I was tasked with understanding a protocol I had no information about.

I wanted to see:

  • Distribution of packet sizes and positions in a conversation;
  • How payloads could be broken down into fields to get an idea of the structure;
  • What patterns could be identified in fields;
  • A state machine for fields which appear to encode state.
