> Do you recommend any references on the relative difficulty of attacking WiFi radios vs. cellular radios?
Unluckily I can't give any recommendations, since I myself still have to read up a lot on the whole topic. :-(

"Even isolated basebands often have a USB bridge (which can be exploited by pretending to be another type of device with a vulnerable USB driver) and direct access to the microphone ... iirc it's using a high-speed serial link, not USB. The microphone is connected to the audio codec, which is connected to the application processor. Uplink audio is sent from there to the baseband."
