The Office of Personnel Management said it will send notices to 4 million people that personally identifiable information may have been compromised by the breach, and said it will pay for 18 months’ worth of credit monitoring for those who were affected.
OPM Director Katherine Archuleta said they’re rushing to try to improve cybersecurity, and insisted they “take very seriously our responsibility to secure the information stored in our systems.”
The revelation comes on the heels of the IRS’s admission that hackers broke into one of its systems and stole the tax transcripts, including some of the most sensitive information possible, about 104,000 taxpayers. In 13,000 cases the hackers used the new information to file false refund requests, stealing as much as $39 million from the federal government.
The new breach affected systems at the Interior Department and the OPM.
Homeland Security Department officials, who are tasked with defending against cyberattacks, said they are working with the FBI to try to get to the bottom of the apparent attack.
