As officials of the Obama administration announced that millions of sensitive records associated with current and past federal employees and contractors had been exposed by a long-running infiltration of the networks and systems of the Office of Personnel Management on June 4, they claimed the breach had been found during a government effort to correct problems with OPM’s security. An OPM statement on the attack said that the agency discovered the breach as it had “undertaken an aggressive effort to update its cybersecurity posture.” And a DHS spokesperson told Ars that “interagency partners” were helping the OPM improve its network monitoring “through which OPM detected new malicious activity affecting its information technology systems and data in April 2015.”
