Five alleged members of the hacker group Anonymous have been charged with recent cyber attacks, including the leak of over 25 million emails from the private intelligence firm Stratfor. Anonymous is a loose international coalition of hackers that conducts cyber assaults for political protest, though they have no central leadership. The arrests are related to the Stratfor leak where stolen emails were provided to Wikileaks, revealing information about government attacks on Wikileaks and Julian Assange. One arrested hacker had previously become an FBI informant, leading the agency to claim it has broken the back of Anonymous.
