Dutch Authorities Dismantle Massive Residential Proxy Botnet Linked to Russian Infrastructure

A Global Network of Hijacked Devices
Dutch law enforcement has announced the disruption of one of the largest botnet operations in recent history, neutralizing a network that had compromised an estimated 17 million consumer devices worldwide. The operation, coordinated by the Dutch police and the National Cyber Security Centre (NCSC), culminated in the seizure of 200 servers located within the Netherlands that served as the command-and-control infrastructure for the botnet.
Unlike traditional botnets that primarily focus on stealing data or encrypting files for ransom, this particular network was designed as a massive residential proxy service. By infecting a diverse array of hardware—including smartphones, tablets, security cameras, and home routers—the operators were able to reroute malicious internet traffic through the IP addresses of legitimate home users. This effectively masked the origin of cyberattacks, making them significantly harder for security software and firewalls to detect, as the traffic appeared to come from trusted domestic connections rather than known malicious data centers.
The Connection to Asocks and Russian Ties
While official Dutch statements have focused on the technical disruption, the operation is closely linked to a residential proxy service known as Asocks. Earlier in 2024, cybersecurity firm HUMAN identified a malware strain dubbed Proxylib, which had infected approximately 190,000 devices and forcibly enlisted them into the Asocks network. This suggests the 17 million devices cited by authorities may represent a much broader ecosystem of both forced infections and questionable “opt-in” agreements.
Asocks has long been a subject of scrutiny among Western intelligence and cybersecurity researchers. Despite listing a British phone number and registering its business in the Seychelles, the service has been consistently linked to Russian-affiliated infrastructure. The business model is aggressively low-cost, offering proxy access for as little as $5 per month, which researchers argue is unsustainable without the use of hijacked residential bandwidth.
The Mechanics of the “Proxy” Threat
The NCSC has highlighted that the rise of residential proxy networks represents a strategic shift in how digital attacks are executed. By using a victim’s home IP address as a waystation, hackers can bypass geographical restrictions and security filters to conduct high-volume DDoS attacks, credential stuffing, and SMS pumping schemes.
This specific takedown follows a pattern of aggressive global enforcement against similar proxy-based threats. In March, a joint effort between German, Canadian, and U.S. agencies dismantled the “Aisuru” and “Kimwolf” botnets, which had hijacked over three million devices. Additionally, Google recently intervened to take down the IPIDEA proxy network, which provided the development kits essential for the Kimwolf operation. These cases illustrate a growing trend where the “commodity” of residential IP addresses has become a primary target for state-sponsored and criminal hacking groups.
Closing the Security Gap
Dutch authorities have not yet released the full technical breakdown of how the malware first entered the 17 million devices, but historical patterns suggest a combination of brute-force attacks on weak router passwords, vulnerabilities in outdated IoT firmware, and malicious Android applications. The NCSC’s updated guidance emphasizes that the sheer scale of this operation demonstrates a systemic vulnerability in consumer hardware.
To mitigate these risks, security experts recommend moving beyond basic password protections. Transitioning to WPA3 encryption for Wi-Fi, disabling remote management features on home routers, and strictly avoiding third-party Android APKs from unofficial sources are critical steps. As botnets evolve from simple spam-engines into sophisticated proxy networks, the burden of security is shifting from the network perimeter to the individual device.
