> Ah, cool, there has been some similar work done before! Is there any documented resources or write-ups of the Xbox Live protocol somewhere?
I talked at defcon a bit last year. https://www.youtube.com/watch?v=HLyZfZMu-5E Otherwise I've been a "source is documentation" kind of guy so far. Could definitely use a high level walkthrough as good as you've done here; I should probably get on that.
> That is a really cool project! How does one make sure the console connects to the server instead of the (now shutdown) Xbox Live servers? Does it e.g. have a hardcoded domain so one can simply add a DNS entry?
Yeah, they bootstrap off of a set of hardcoded domains. The config screens on the boxes let you specify a DNS server, so the project runs it's own DNS server that's basically when obi-wan says "of course I know him, he's me". Then the relative lack of any public/private crypto lets us take over as long as we know the preshared key in the individual xbox's eeprom.
