Ok im new to the xbox (360) scene but i have an idea,
I was doing some network sniffing of my xbox live connection and i found some stuff out,
1st: the xbox's connection to xbox live is not encrypted in any way (exept a couple of handshakes which are only ssl)
2nd: files (demos) sent over are stored in encrypted cab files (xcp)
3rd: pricing for xbox live content is sent over in unecrpted xml files.
So what i was thinking was possible encrypting other content like a full xbox 360 game into a xcp file,
then packet editing the connection so instead of downloading (from xbox live) and then exstracting a demo it downloads a full game (from comptuer) installes the "demo" but when you goto run this "demo" its aculy a full game.
what you guys think?
