Hackers based in China broke into the Office of Personnel Management‘s computer networks in March and the government believes they wanted to access data on security clearances, the New York Times reported Wednesday.
A Department of Homeland Security official confirmed the infiltration and said that authorities found no loss of “personally identifiable information,” according to the newspaper.
The Times reports that an emergency response team was formed to investigate the hacking incident and mitigate any security risks.
OPM keeps all federal employees’ personal records, including their security clearance applications that contain foreign contacts and employment history.
The agency also runs a confidential e-QIP portal where federal workers update their personal data, according to the newspaper.
An OPM representative says that threat monitoring systems worked to alert the agency personnel of the network compromise in mid-March.
