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.

Healthcare facilities operator Nutex says patient, employee data stolen in August incident
The Gentlemen ransomware gang claims the theft of patient and employee data from healthcare operator Nutex Health, which disclosed the extortion in SEC filings.
Nutex Health said in an 8-K filing that intruders broke into its servers and exfiltrated patient, employee, provider and confidential financial data, and that it is being extorted with threats to publish the information. A Texas class action was filed after the company's August 24 disclosure, and Nutex cannot yet estimate the incident's impact. The Gentlemen ransomware-as-a-service gang, active since September 2025 and believed Russia-based, listed Nutex on its leak site; Dragos ranked it third among groups attacking industrial organizations in Q2 2026 with 125 claimed attacks.

Ransomware group hijacks hospital system’s Facebook page amid ongoing cyberattack fallout
'The Gentlemen' ransomware group hijacked AnMed's Facebook page, claiming theft of 6TB of sensitive patient data during an ongoing cyberattack on the hospital system.
AnMed, a nonprofit medical system with four hospitals in Georgia and South Carolina, is still responding to a July 26 cyberattack involving malware, with 10 facilities remaining closed as of Monday. On Tuesday its Facebook page displayed unauthorized posts claiming 'The Gentlemen' ransomware group exfiltrated 6 terabytes of data, including records on sexual assault, mental health, abortions and harassment; AnMed said the claims are unverified and patient data impact has not been confirmed. The Gentlemen, believed founded by a former Qilin affiliate using the moniker 'hastalamuerte,' extorted 332 victims in the first five months of 2026 per CheckPoint and claimed 125 industrial attacks in Q2 2026 per Dragos. The group typically breaches networks through edge devices, credential brute-forcing and known vulnerabilities, and offers affiliates tools to disable EDR.
