The newest name in hacking groups? LulzSec.

[thewayne]

They claim responsibility for some of the Sony hacks (and Sony has been hacked a couple of more times). A couple of weeks ago they hacked PBS for airing an unfavorable story about Anonymous.

And now they've hacked an affiliate of the FBI!

I don't think they're financially-motivated, but who can tell.
