Unluckily I can't give any recommendations, since I myself still have to read up a lot on the whole topic. :-(
- walterbell 10y agoThere was a 2014 thread on the Tor blog about Android security, where a commenter claimed that one of the Nexus phones had a baseband that was isolaed by a serial link, https://blog.torproject.org/blog/mission-impossible-hardening-android-security-and-privacy#comment-55372 https://blog.torproject.org/blog/mission-impossible-hardenin... "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."
