Chinese hackers broke into the computer systems of United States government agency that keeps the personal information of all federal employees. The attack occurred on the Office of Personnel Management and Senior American officials believe that the attackers successfully gained access to some of the agency’s databases in March before the federal authorities detected the threat and blocked them from the network. The hackers targeted the files of tens of thousands of federal employees who have applied for top-secret security clearances, the New York Times reported. The databases they managed to hack include employment records, people seeking security clearance list their foreign contacts, previous jobs and personal data.
