Hacking network Anonymous has released a recording of a conference call between the FBI and UK police in which they discuss efforts against hackers. http://www.bbc.co.uk/news/world-us-canada-16875921 When the two most famous policing organisations in the world can't even prevent themselves from being hacked, what does that tell you?
anonymous has accomplished very little, they specialize in DDOS attacks, SQL injects, sending pizza's to people and defacing web pages. I generally support their cause, but haven't seen them really do anything epic, heck most of it can't even really be considered "hacking"
