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.

China slammed the U.S. Treasury's sanctions against cybersecurity firm Integrity Technology Group for its alleged role in hacking incidents.

On Friday, the Treasury Department imposed sanctions on Chinese company Integrity Technology by restricting its access to U.S. property and bank accounts.

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.
