The sites were replaced by a banner proclaiming ASCII that the sites had been "owned", with the hackers themselves and the credit.
Although the source indicates that the responsible party might be the Internet group called "Anonymous", it seems that the group itself lacks coherence, and doesn't seem to be the same "Anonymous" that people associate with 4chan.
A copy archived from one of the hacker group's discussions indicates they may have copied private information like resumes, one of the councils, even game source code, but of course this incident is not yet clear.
