Google Takes Down NetNut Residential Proxy Network Controlling ~2 Million Home Devices
What Happened — Google’s Threat Intelligence Group, in partnership with the FBI, Lumen and other agencies, announced that it has crippled NetNut (also known as Popa), one of the world’s largest residential‑proxy services. The operation removed millions of compromised home devices from the network, dramatically reducing its capacity to relay traffic for malicious actors.
Why It Matters for Compliance & Audit Readiness
- The incident illustrates how a third‑party service can become a hidden conduit for illicit traffic, underscoring the need for continuous vendor‑risk monitoring and documented due‑diligence.
- SOC 2‑aligned programs must map and retain evidence of controls that detect and block unauthorized proxy use, providing a defensible audit trail.
- Control‑mapping capabilities (e.g., Verisq’s Trust Center) enable organizations to prove that they have identified, assessed, and mitigated such external risk factors in real time.
Who Is Affected — Financial services, SaaS platforms, advertising networks, and any organization that relies on outbound internet traffic integrity; also the millions of home users whose devices were hijacked.
Recommended Actions
- Review and update third‑party risk registers to include proxy‑service providers and “shadow” infrastructure.
- Deploy network‑traffic monitoring that flags residential‑proxy IP ranges and correlates with SOC 2 access‑control logs.
- Collect and retain evidence of these controls in a continuous‑compliance repository for audit readiness.

Technical Notes
- NetNut operated by compromising home routers and IoT devices, likely via malware implants that opened outbound proxy tunnels.
- No public CVE; the threat vector was malicious code on consumer hardware used to route traffic for credential‑stuffing, fraud, and evasion.
- Google’s takedown leveraged sink‑holing, DNS‑level blocking, and coordinated takedown notices.
