Yeah that’s why my focus was on isps detecting this outbound - if only through feeds like shadow server - and cutting off infected customers.

It’s very difficult to classify DDoS traffic at the ASN level unless you can see it across ASNs on the Internet backbone, then and correlate it using sophisticated pattern recognition. This what services such as Black Lotus, CloudFlare, and Fastlick do. Especially for small ISPs, this is impossible to do in-house, at least today anyway. Hackers quickly learn how all these DDoS recognition services work, so it’s a constant battle or whack-a-mole trying to stay ahead of them and their information hiding techniques. There are CPE devices — NG enterprise firewalls — that can detect and block some large output streams. But customers aren’t willing to pay a $2000 setup fee and turn over the shelf space and endure the noise footprint for these products. But you’re right about one thing: ISPs, where they can identify abusive outbound traffic, can turn off those customers and leave it to them clean up their home networks. -mel On Jan 17, 2026, at 5:50 PM, Suresh Ramasubramanian <[email protected]> wrote: Write it and submit it to the NYT and that crowd would just call it mass media lies. Whatever happened to all the walled gardens Comcast and others were working on? If you see this traffic just cut the connection based on the customer bumming free tv with a knockoff Chinese device, if not for the malware. --srs ________________________________ From: Mel Beckman via NANOG <[email protected]> Sent: Sunday, January 18, 2026 9:41:54 AM To: Tim Burke <[email protected]> Cc: [email protected] <[email protected]>; Corey Smith <[email protected]>; Roland Dobbins <[email protected]>; Mel Beckman <[email protected]> Subject: Re: ISP Operators AISURU/Kimwolf botnet You should write the article and submit it to the New York Times technology group. I believe David Pogue still works there, and he is a tech guy, so maybe he would be a good vehicle to get it published. I used to work with DAVID at Macworld magazine. But it’s not the job for an ISP, or even something an ISP could get the major media to publish. -mel via cell > On Jan 17, 2026, at 4:50 PM, Tim Burke <[email protected]> wrote: > > The problem I see is that an article like this is intended for an > IT/security professional audience. > > These TV piracy boxes are often used by uneducated folks that would not read > such an article.
