A remarkable twist in the story of the biggest data breach in U.S. history. The Office of Personnel and Management (OPM) previously said they discovered the breach when it had “undertaken an aggressive effort to update its cybersecurity posture”.
However, that “update” claim is somewhat disingenuous. The hack was actually discovered by a cyber software company as it was running a product demo on the system. The company discovered embedded malware that existed inside the OPM for over a year…
WASHINGTON DC – 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.”
Those statements may not be entirely accurate. According to a Wall Street Journal report, the breach was indeed discovered in April. But according to sources who spoke to the WSJ’s Damian Paletta and Siobhan Hughes, it was in fact discovered during a sales demonstration of a network forensics software package called CyFIR by its developer, CyTech Services. “CyTech, trying to show OPM how its cybersecurity product worked, ran a diagnostics study on OPM’s network and discovered malware was embedded on the network,” Paletta and Hughes reported.
And, according to federal investigators, that malware may have been in place for over a year. US intelligence agencies have joined the investigation into the breach. But it’s still not even clear what data was accessed by the attackers. (read more)
