In early December 2024, the U.S. Department of the Treasury experienced a cybersecurity breach. Though China denies involvement, the breach is attributed to a Chinese state-sponsored Advanced Persistent Threat (APT) actor.

The Cybersecurity and Infrastructure Security Agency (CISA) said Monday that there is “no indication” other federal agencies were impacted by the recent breach at the Treasury Department.

Ill., the top Democrat on the House select committee on China, raised concerns about the breach to Treasury Secretary Janet Yellen and asked for a meeting to discuss the situation by Jan. 15. A Treasury official told Semafor that the agency has already offered briefings to Congress.
