A tweet sent by the hacker group Anonymous claims the group has broken into the network of defense contractor ManTech International and intends to release seized documents within 24 hours. The hacker group has led a long string of successful raids into corporate networks, claiming to use that hacking as a means to draw attention to causes and issues it embraces. International law enforcement efforts have been stepped up recently to try and apprehend members of the group, which recently broke into another contractor with defense ties, Booz Allen Hamilton.”]
