The UFC has waged a number of wars against cyberspace in the past in the fight to stop online piracy, a hot topic these days in light of SOPA/PIPA legislation. Now it appears one group of hackers have decided to fire back.

For the past hour has been down, instead directing interested browsers to a different website hosted by the “Underground Nazi H4ck3rGr0up”. It also appears, at least on the surface, as though their database may have been tampered with as fighter profiles are now returning a “ERROR 404 – PAGE NOT FOUND” message.

The UFC has not issued any sort of statement through other online means such as Twitter/Facebook but there is little doubt Zuffa employees are furiously working on fixing the issue.
