It would seem that there's a trainer for the game (not readily available to the public) if you have a modded 360.
This kind of stuff shouldn't be possible when a game is online only. Hopefully Bungie will figure out a way to prevent this kind of thing.
So, if you see anyone that's moving a lot faster than normal, jumping über high, not dying regardless of how much damage they take, one-shotting almost everything, etc., report them immediately.
