The Justice Department on Wednesday said it shut down several platforms linked to China that hacked the Senate and multiple government agencies.

Officials said a Chinese company linked to the Beijing government hacked into multiple federal agencies, including the Federal Reserve, National Institutes of Health, National Aeronautics and Space Administration, and the Departments of Justice, Energy, and Health and Human Services. The DOJ and FBI seized two domains, QScan and QTRouter, after investigators determined QTFY, or the Nanjing Xinjiuwei Network Technology Company, was using those systems to hack into the Senate, U.S. government agencies, and sensitive networks nationwide, according to officials.
