Tescat
======

This tool analyzes UDP packets being broadcast on a specified port to the local network or from a PCAP file. It will identify packets that are unique since the start of the process.

Tescat is especially useful when you're analyzing a network with a large amount of baseline traffic that does not vary frequently and you want to identify anomalies some time after the initial baseline.

This was developed while auditing the internal LAN on the Tesla Model S.
