Srsly Risky Biz: China's Private Sector Botnets Are Worth Disrupting

DoJ seized domains of Chinese espionage botnet platforms QScan and QTRouter, run by private firm QTFY for MSS and PLA targeting.

The US Department of Justice disrupted QScan, a distributed vulnerability scanning system with nearly a decade of internet scanning data, and QTRouter, a covert communications platform routing traffic through compromised IoT devices, operated by QTFY under Chinese company Nanjing Xinjiuwei Network Technology. FBI and NSA advisories say QTFY customers include China's Ministry of State Security and the People's Liberation Army, targeting federal agencies, the US Senate, hospitals, telecoms and financial institutions. This is the third Chinese state-backed botnet disrupted since December 2023, following the KV botnet (Volt Typhoon) and Raptor Train (Flax Typhoon), and a sister network, JDY, has more than doubled since the KV disruption. Separately, the Qilin ransomware group claimed a breach of the ATF's CALEA system, briefly publishing 6.3 GB of case folders and forensic data.

FBI Disrupts China-Linked QTFY Infrastructure Used to Steal Data From U.S. Organizations

FBI and Lumen disrupted QTFY's QScan and QTRouter botnet platforms used by Chinese state-sponsored hackers to conceal intrusions into U.S. agencies.

The U.S. DoJ announced court-authorized seizure of domains behind QScan and QTRouter, operated by the Chinese state-sponsored group QTFY and employed by Nanjing Xinjiuwei Network Technology Company. QTFY has been active since May 2018 and targeted NASA, the Federal Reserve, the Department of Energy, DoJ, HHS, NIH, the U.S. Senate, and academic institutions. QScan exploits vulnerable IoT devices, feeding them into QTRouter, an OpenWrt-based proxy obfuscation network likened to an operational relay box (ORB) that masks attack origins. The group exploited zero-days such as Ivanti CSA flaws CVE-2024-8190, CVE-2024-8963, and CVE-2024-9380, plus numerous N-days, and maintained persistence with RATs, web shells, and legitimate credentials.

DoJ Corrects China Hacking Claim, Says U.S. Agencies Were Targets, Not Victims

DoJ corrected its statement to say US federal agencies were targets, not confirmed victims, of China-linked group QTFY's intrusions.

The US Department of Justice revised its press release to list NASA, the Federal Reserve, Department of Energy, DoJ, HHS, NIH and the US Senate as 'among the targets' of QTFY (aka QT AND QTCYBER), rather than victims. QTFY, active since 2018 and linked to Nanjing Xinjiuwei Network Technology Co with payments suggesting MSS sponsorship, operates the QScan vulnerability scanning platform and QTRouter obfuscation network, which underpin the Fast Labyrinth encrypted ORB relay network built from infected IoT devices and leased VPSs. The FBI seized qtproxy[.]xyz, qt-proxy[.]org and qt-team[.]com, disrupting QScan and QTRouter, while Lumen Black Lotus Labs reported the actor industrialized ORB networks for China-linked espionage. A 2019 NASA intrusion attempt exploited CVE-2019-11510, a critical Pulse Secure VPN flaw.
