Dutch police and the Netherlands’ National Cyber Security Center disrupted a botnet spanning roughly 17 million infected devices by taking offline about 200 servers hosted in the Netherlands. Authorities said the network included compromised computers, mobile phones, IoT devices, and routers, and that the investigation began after a security researcher alerted NCSC-NL. While officials did not publicly name the botnet, reporting tied the infrastructure to Asocks, a commercial residential and mobile proxy service, and to prior research on covert proxy enrollment through the PROXYLIB library and LumiApps SDK ecosystem.
The takedown highlights growing abuse of residential proxy networks, which can mask malicious traffic behind trusted consumer IP addresses and support operations including DDoS attacks, spam, credential stuffing, brute-force attacks, click fraud, SMS pumping, phishing, online fraud, and malware delivery. The action follows broader Dutch enforcement against malicious infrastructure, including the seizure of more than 800 servers tied to THE.Hosting, a Russian-linked bulletproof hosting network associated with scanning, botnet recruitment, cryptomining, credential theft, and exploitation of exposed services; researchers said that operation had limited effect because much of the network’s routed infrastructure remained active across multiple countries.

Dutch National Police and the Netherlands' NCSC disrupted a botnet by taking offline 200 servers in the Netherlands that controlled roughly 17 million infected devices. The investigation began after the NCSC received a report from a security researcher, and reporting linked the infrastructure to the Asocks proxy network.
Roughly a week after the May 18 action, ELLIO reported that scanning from AS209847 continued at normal daily levels despite some IP ranges being withdrawn from routing. The activity included probing for databases, industrial control system protocols, CVE-2017-17215, and WinRM.
On 2026-05-18, Dutch authorities seized more than 800 servers tied to THE.Hosting and arrested two people associated with the bulletproof hosting network. Researchers linked THE.Hosting to a Russian-linked infrastructure lineage previously operating as Stark Industries Solution and PQ Hosting Plus S.R.L.
