GoKawiilFBI takes down proxy network used in Chinese state hacking campaigns
The FBI dismantled infrastructure belonging to a 'quartermaster' service that supplied reconnaissance, proxy relays, and routing tools to Chinese state-linked hackers. Lumen Technologies' Black Lotus Labs had spent a year tracking the system, identifying four components—QScan, Fast Labyrinth, QTRouter, and QTProxy—that worked together to profile targets and hide malicious traffic.
GoKawiil's interpretation of the reporting above, not reported fact.
This service acted as shared infrastructure supporting espionage against U.S. military, government, research, healthcare, and energy targets, meaning its takedown could disrupt multiple campaigns at once rather than a single actor. It also shows how private threat-intel firms and federal law enforcement are increasingly collaborating to expose and dismantle the tooling behind nation-state hacking rather than just individual intrusions.
- FBI dismantled a reusable proxy and reconnaissance network tied to Chinese cyber espionage.
- The infrastructure included four tools: QScan, Fast Labyrinth, QTRouter, and QTProxy.
- Victims spanned U.S. defense, government, academic, healthcare, and critical infrastructure sectors.
