The Justice Department did not detail the damage to the agencies or other targets from the computer intrusions.

An affidavit identified the U.S. Department of Energy, the Department of Health and Human Services (HHS), the National Institutes of Health (NIH), and four unnamed companies in the United States and South Korea as additional victims of the hackers.

“Other targeted networks include those operated by hospitals, telecommunications providers, power companies, financial institutions, and defense contractors,” the affidavit stated.

China-Linked Group Identified

Court documents unsealed in California federal court said that a “People’s Republic of China (PRC) state-sponsored group” known as “QTFY” created and operated the hacking platform.

The affidavit added, “Since at least 2018, QTFY computer infrastructure has been used to compromise critical infrastructure and other sensitive networks in the United States and worldwide.”

According to filings, QTFY was employed by Nanjing Xinjiuwei Network Technology Company, a China-based company.
