The U.S. Department of Justice (DOJ) announced on Wednesday that it has successfully disrupted a sophisticated cyber-espionage operation linked to China. According to federal officials, the hacking campaign targeted several high-profile U.S. government entities, including NASA and the U.S. Senate, as well as various federal networks.

As part of the enforcement action, the DOJ seized two primary hacking platforms identified as “QScan” and “QTRouter.” These tools were reportedly utilized by a state-run hacking group operating under the direction of a China-based company known as Nanjing Xinjiuwei Network Technology Co. The DOJ stated that these platforms were designed to infiltrate and monitor sensitive government systems, though the specific extent of the data compromised remains under investigation.

This disruption is the latest in a series of federal actions aimed at curbing state-sponsored cyber activities originating from China. While the DOJ has confirmed the seizure of the infrastructure, it has not yet provided a comprehensive list of all agencies affected or the total volume of data potentially accessed during the operation. The investigation into the scope of the breach and the identities of the specific individuals involved remains ongoing.
