The U.S. Justice Department is investigating a cyber breach involving the federal court records management system, the department's top national security attorney told lawmakers on Thursday.
Matt Olsen, head of the Justice Department's National Security Division, alluded to the threat of cyber attacks by foreign nations as he informed the U.S. House Judiciary Committee about the investigation into an "effort to compromise public judicial dockets."
Olsen made those remarks in response to questions from Representative Jerrold Nadler of New York, the panel's Democratic chairman, who said the committee had only in March learned of the "startling breadth and scope" of the breach.
The Administrative Office of the U.S. Courts in January 2021 said it was adding new security procedures to protect confidential or sealed records following an apparent compromise of its electronic case management and filing system.

Olsen said he could not speak "directly to the nature of the ongoing investigation." But he noted his division was focused on the risk of cyber attacks by foreign nations like China, Russia, Iran and North Korea.
"This is of course a significant concern for us given the nature of the information that is often held by the courts," Olsen told lawmakers, adding the department was working with the judiciary to investigate and address the matter.
