A second breach of the Office of Personnel Management by hackers believed to be associated with China exposed sensitive security clearance information of intelligence and military personnel, officials confirmed Friday, potentially creating an intelligence disaster for U.S. spies stationed abroad.
“During the investigation into the cyber intrusion of OPM that compromised personnel records of current and former Federal employees announced last week, OPM along with its interagency partners became aware of the possibility of a separate intrusion affecting a different set of OPM systems and data,” a senior administration official said in a statement.
Officials investigating the OPM hack announced last week discovered the second breach on Monday, the official said.
“On June 8, as the investigation proceeded, the incident response team shared with relevant agencies that there was a high degree of confidence that OPM systems containing information related to the background investigations of current, former, and prospective Federal government employees, and those for whom a federal background investigation was conducted, may have been exfiltrated,” the official said. “Since the investigation is ongoing, we are in the process of assessing the scope of the information that has been compromised, but we expect OPM will conduct additional notifications as necessary.”
