4. Anonymous vs. FBI
February 2012: The FBI, Scotland Yard and other top law enforcement agencies around the world hold a confidential conference call to discuss the ongoing investigations into Anonymous and related splinter groups like Lulzsec, Antisec and others. Also on the line, listening in, is Anonymous itself. Anonymous ultimately posts a nearly 17-minute recording of the call on YouTube and other sites. The FBI confirms that the recording is authentic, "illegally obtained" and that "a criminal investigation is under way to identify and hold accountable those responsible."
