It looks like hacker group LulzSec finally had its Fredo moment. From Reuters:
The Federal Bureau of Investigation has arrested three suspected members of the hacker group LulzSec and charges will be made public against two more, a law enforcement official told Reuters on Tuesday.
LulzSec, an underground group also known as Lulz Security, along with fellow hacking group Anonymous have taken credit for carrying out a number of high-profile hacking actions against companies and institutions including the CIA, Britain's Serious Organized Crime Agency, Japan's Sony Corp and Mexican government websites.
Last month, the activist group Anonymous published a recording of a confidential call between FBI agents and London detectives in which the law-enforcement agents discuss action they are taking against hacking.
