Hacker reveals smart meters are spilling secrets about the Texas snowstorm
Note to people outside of the US who are worried about this:<p>The rest of the world uses 3G/4G modems in their smart meters, they are usually also connected to a different APN than generic mobile data. Sometimes multiple meters are connected to a central hub with a physical wire (in apartment buildings for example). The hub is then the only gateway to the internet.<p>The hack in question is only viable because of the weird way US smart meter collection is done.<p>US Smart Meters use RF to shout out their values everywhere like an RF beacon. A power company vehicle drives around the neighbourhood, collecting the values, storing them and moves on.<p>Source: I did smart metering software for L+G.
