It was bound to happen eventually. Despite Infinity Ward doing everything they could to keep hackers out of Modern Warfare 3 (even going so far as to fly out some of the hackers themselves to consult on how to stop them), the game has now been hacked.
You can see the results of some of these hacks in the videos below. The videos include users on the Xbox 360 using hacks such as walking AC-130′s, infinite ammo, superspeed, and general all-around God-mode for the glitcher.

It’s really unfortunate that this would happen on the same night that the MW3 servers went down. No word yet on whether or not the two are related.
