The largest criminal copyright cases on Internet piracy has seized the Web site Megaupload and charged seven people connected with it. Anonymous strikes back on Megaupload Revange.  The hacker collective that calls itself Anonymous attacked the Web sites of the Justice Department, Universal Music, Record Label EMI,  French copyright authority HADOPI , FBI, and several major entertainment companies and trade groups in retaliation for Mega-upload’s seizure.

Russian news service RT claims this is the largest coordinated attack in Anonymous’ history—over 5,600 DDoS zealots blasting at once.
