U.S. Employee Data Breach Tied to Chinese Intelligence

Sources say the Chinese hacking group suspected of stealing sensitive information about millions US current and former federal employees has a different mission and organizational structure than the military hackers who have been accused of other U.S. data breaches.
Two people close to the U.S. investigation said While the Chinese People's Liberation Army typically goes after defense and trade secrets, this hacking group has repeatedly accessed data that could be useful to Chinese counter-intelligence and internal stability.
Washington has not publicly accused Beijing of orchestrating the data breach at the U.S. Department of Homeland Security's Office of Personnel Management. Meanwhile, China has dismissed as "irresponsible and unscientific" any suggestion that it was behind the attack.
