The Federal Reserve, the U.S. Senate, the Department of Justice, NASA, and other federal agencies were victims of computer intrusion by a Chinese state-sponsored hacking group, the DOJ said on Wednesday morning as it announced the seizure of online domains used for hacking platforms.

The hacking platforms, known as "QScan and QTRouter," were "used to target U.S. critical infrastructure and other sensitive networks," the DOJ said in a statement.

"Other targeted networks include those operated by hospitals, telecommunications providers, power companies, financial institutions, and defense contractors," a court filing said.

Other federal agencies that were victims of computer intrusion by the platforms were the Energy Department, the Health and Human Services Department, and the National Institutes of Health, according to the DOJ.

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