The U.S. Department of Justice (DoJ) on Wednesday announced the disruption of two hacking platforms named QScan and QTRouter operated by Chinese threat actors to target critical infrastructure and other sensitive networks in the country.

The activity has been attributed to a Chinese state-sponsored group known as QTFY, employed by Nanjing Xinjiuwei Network Technology Company (南京鑫玖维网络科技有限公司).

"Among the victims of QTFY computer intrusion activity are the National Aeronautics and Space Administration, Federal Reserve, Department of Energy, Department of Justice, Department of Health and Human Services, National Institutes of Health, and the U.S. Senate," DoJ said.

Damon Rouse, a security researcher at Lumen Black Lotus Labs who has been tracking the activity for over the past 18 months, told The Hacker News that the digital quartermaster has been active since May 2018. Nanjing counts both China's Ministry of State Security (MSS) and the People's Liberation Army (PLA) among its customers.

Lumen said it began collaborating with the U.S. Federal Bureau of Investigation (FBI) on QTFY about a year ago. "The targeting was throughout the western world and beyond, especially with regard to academia," the company added. "They just love hitting research communities given the collaborative nature of advanced science."
