Chinese hackers broke into computers at the U.S. Chamber of Commerce and had access to everything on its systems, report says. The highly targeted attack appears to have been carried out by an organized group of hackers thought to be affiliated with the Chinese government. The attackers appeared to know whom to target and what data to go after, the chamber’s chief operating officer says. About six weeks’ worth of email belonging to about 50 members of the chamber appears to be stolen, the Wall Street Journal reports.”]
