“China is building massive databases of Americans’ personal information by hacking government agencies and U.S. health-care companies, using a high-tech tactic to achieve an age-old goal of espionage: recruiting spies or gaining more information on an adversary, U.S. officials and analysts say.
Groups of hackers working for the Chinese government have compromised the networks of the Office of Personnel Management, which holds data on millions of current and former federal employees, as well as the health insurance giant Anthem, among other targets, the officials and researchers said.”
