Noah Hellman recently wrote a fascinating article where he explains how he tinkered with 1st-gen Xbox and Halo to understand how Halo's System Link protocol (which allows running a multiplayer game locally) works.
I don't have the skills to go that deep in reverse engineering, so I found the explanations super interesting and exciting.
Noah uses some "basic" troubleshooting tools, such as tcpdump and gdb
to figure out how the whole thing works, then openssl to decrypt the traffic,
and then writing some C code to perform a kind of MITM attack.
Again, really worth reading!
