> home router makers could intervene here and let their owners know when they’ve likely been hacked How? A couple of years ago I had an email from our ISP telling me that "common port X is open on your router" (forwarded to a box exactly as I set it up) and asking if I could "fix the problem". Except it wasn't a mistake or a configuration error, I deliberately set it up that way.
