Hackers broke into federal government computer networks and compromised both the Office of Personnel Management and the Interior Department, putting almost every current and former government employee at risk. This could be the biggest data breach ever, and officials think that China is behind the attack.
The breach could expose tons of personal information belonging to government employees, because the Office of Personnel Management performs over 90% of federal background checks.
A U.S. official, who declined to be named because he was not authorized to publicly discuss the data breach, said the breach could potentially affect every federal agency. One key question is whether intelligence agency employee information was stolen. Former government employees are affected as well.
The Chinese government has denied any involvement in the attack and claims that the accusations coming from the U.S. aren't verified.
