Stratfor was hacked in January by unknown individuals claiming to be part of the “Anonymous” movement, who allegedly gave more than 5 million of Stratfor’s emails to WikiLeaks. The site began publishing the stolen documents on Monday, claiming they revealed a private spy agency used by corporations and top government officials. Hackers at the time revealed a list of the firm’s clients, which includes companies like Apple, Microsoft, Coca Cola, Dow, the U.S. Defense Department, the U.S. Air Force, the U.S. Marines and others.
