Anonymous announced recently it was going after North Korea for their role in the nuclear escalation. Wednesday April 3, 2013, it was announced that they had taken over North Korea's Twitter and Flickr accounts.
Two press releases were issued by Anonymous. The first of which can be found here. The second of which can be found here. The second release goes so far as to use a famous line from the move Tropical Thunder...very amusing.
On a personal note, while these guys have been known to do some questionable acts, recently I am really getting a kick out of their direction. Although these acts are illegal in the US and most other countries, at least this disobedience is not violent. There is something to be said about that.
