Well it is all a matter of looking at what you'd call a hacker. If it's the ones who steal Credit card numbers from servers then yes, PS3 is more infamous for that but XBOX has had it's fair share. If you mean the ones who modify a game to have god mode etc. then I'd be willing to say the CoD community on Xbox has more than the PS3. Though I am not saying PS3 doesn't have it's fair share of those modders.
