Treasury Sanctions China-based Hacker Involved in the Compromise of Sensitive U.S. Victim Networks

WASHINGTON — Today, the Department of the Treasury’s Office of Foreign Assets Control (OFAC) is designating Zhou Shuai, a Shanghai-based malicious cyber actor and data broker, and his company, Shanghai Heiying Information Technology Company, Limited (Shanghai Heiying). In collaboration with another malicious cyber actor, U.S.-sanctioned Yin Kecheng, Zhou Shuai illegally acquired, brokered, and sold data from highly sensitive U.S. critical infrastructure networks. Malicious cyber actors, particularly those operating in China, continue to be one of the greatest and most persistent threats to U.S. national security, as highlighted in the Office of the Director of National Intelligence’s most recent Annual Threat Assessment.“Today’s action underscores our resolve to hold accountable malicious cyber actors like Zhou who continue to target U.S. government systems, the data of U.S. companies, and our citizens,” said Acting Under Secretary of the Treasury for Terrorism and Financial Intelligence Bradley T.
