Mysterious cyber-attacker hits at federal websites, crisis averted?

It looks like a nefarious cyber-attack which affected several federal websites in the United States was a little more far-reaching than initially thought. The attack -- which started on the 4th of July -- targeted websites in both South Korea and the United States, including the Treasury Department, Federal Trade Commission and Secret Service. Various problems were still being reported days later, and while there's no official word on who the attackers were, those "people familiar with the matter" we know and love seem to be pointing their fingers at North Korea. So far as we know, no irreparable damage has been done, but we're not sure anyone would tell us if it had.
