Prosecutors filed a document which reveals ex LulzSec hacker Sabu helped US authorities stop more that 300 cyber attacks against US targets. Prosecutors are demanding Judge Loretta A. Preska for leniency for Sabus cooperation. Sabu was one of the leaders of the group which breached many high profile targets during the last years, like Sony Pictures in 2011. The group also claimed responsibility for taking down many other notorious targets such as AT&T, Viacom, Disney, NBC Universal, The Sun, The Times and the CIA.”]
