Niche startup idea, VPN for your mobile device that can analyze and block traffic. Block entire countries, 3rd parties, etc. Give realtime feedback on their dashboard as applications are loaded. Could also be useful as a developer application profiling tool.

Facebook attempted such a thing already, and was caught exploiting it. VPN apps for the purpose of traffic control and monitoring are dangerous as they rely on some other party. I could do the same thing without ever needing a service for that. Setting up a monitored VPN gateway is no rocket science for me, I could do that, but the folks using crappy apps couldn't. And I would still need a way to map traffic to specific apps to identify unnecessary/malicious traffic. There is no other way as only via the internal iOS firewall. I wonder how the team behind that report managed to do that what they claim they did.

Using a clean installed of the OS, removing network access for almost everything and installing a single app, and baselining background network traffic, I don't think it would be difficult or too noisy to see application specific network activity.

This is indeed what we (originators of this location tracking research) do.

Do you have it as a service, or a set of OpenVPN scripts I can install? I could see a nice Grafana dashboard of my outbound traffic. Install your cert on my device, break into sessions and then further analyze traffic.

This will be a commercial service, in order to fund ongoing research efforts allowing us to quickly discover and block all possible forms of tracking, phishing, and other malicious traffic.

That said, in the future, lists will be published for folks with the ability and time to operate a Pi-Hole for themselves, if preferred.

Your shame list will be golden! Please post to HN when you launch, I'll sign up.
