THIS is exactly what I'm talking about when I created my RadioInstigator tablet. https://hackaday.com/2019/06/05/mobile-sigint-hacking-on-a-civilians-budget/ https://hackaday.com/2019/06/05/mobile-sigint-hacking-on-a-c... Radio in all its forms has been considered a "safe" way to send and receive digital data. That was only because attacking signals was traditionally only in the hands of nation-states. The hardware and know-how was erudite and tremendously expensive. That quaint idea is no longer true. Locally, our city is installing IoT water monitors that chirp out consumption every 1/2-1h. A simple replay attack could cause peoples' water bills to go in excess of $30k. Our power meters are similar. The tornado siren alert structures also sit on 400MHz spectrum, and are trivial to remotely trigger with no way to turn off. The system was built to trust any radio signal that it understands, full stop. So seeing that planes are also attackable this way is obvious to me. Of course the authentication/authorization/auditing/encryption/signature part of the stack cost money, so was not included. What do we do? Well, We (royal) fix the grid in all places to do things right. Individually, be wary and very careful in the radios you put in your vicinity.
