We take our cell phones with us everywhere – which makes them the perfect tracking device. Just walking around with your device will give your location away in multiple ways. But even if you had no apps on your phone, the cellular chips in our devices will constantly be interacting with every cell tower that’s in range, negotiating the best tower to talk to, whether to use 5G or something else, and authenticating to the network – even in Airplane Mode. Cell site simulators (aka Stingrays or IMSI catchers) can be used to trick your phone into give away your location. The Electronic Frontier Foundation (EFF) has developed a cheap, easy-to-setup device that can try to discover and report these devices. Today I interview an expert panel about the clever Rayhunter project: Cooper Quintin, The Gibson, and OopsBagel.
