The Biden administration sanctioned a hacker and cybersecurity company over their suspected links to a breach of the U.S. Treasury Department and China’s Typhoon hacking groups, respectively.

State Department spokesman Matthew Miller said Friday that Shanghai-based Yin Kecheng is a cyberattacker affiliated with China’s Ministry of State Security that was associated with a recent hack of the Treasury Department.

Mr. Miller said Sichuan Juxinhe is a cybersecurity company with direct involvement in the cyberattacks of Salt Typhoon, a China-affiliated hacking group accused of breaching Western telecommunications infrastructure.

“In addition to sanctions, the U.S. Department of State’s Rewards for Justice (RFJ) program, which is administered by the Diplomatic Security Service, is offering a reward of up to $10 million for information leading to the identification or location of any person who, while acting at the direction or under the control of a foreign government, engages in certain malicious cyber activities against U.S. critical infrastructure in violation of the Computer Fraud and Abuse Act,” Mr. Miller said in a statement.

Deputy Treasury Secretary Adewale “Wally” Adeyemo said in a statement that his department would continue looking for ways to hold cyberattackers accountable for targeting the American people, businesses, and federal government — particularly the Treasury Department.

The Treasury Department’s Office of Foreign Assets Control will impose the sanctions, which block the affected entities from holding property and interests in the U.S. and limit Americans from doing business with the hacker and the company.

Earlier this month, the Biden administration announced sanctions against Beijing-based Integrity Technology Group in an attempt to strike at China’s Flax Typhoon hacking group. The hacking collective is accused of targeting U.S. businesses, government agencies, telecom providers and media organizations.

Whether the sanctions have a desired punitive or deterrent effect remains to be determined. The sanctioned entities appear to all reside outside U.S. jurisdiction.
