RRZishe what can they do with audio routing control?
RRZishe route audio through the cars microphones and the cars speakers, or through googles assistant.
The problem is that cars (and googles assistant) are known to keep recordings of the microphones. This is not done with bad intent. Perhaps it's just a cache for performance reasons or voice analytics, or some type of black box recordings in case you have a severe car accident. However, bad can be done even if it was not intended by design. If it's a modern car, itΒ΄s basically a computer with remote access for the vendor (and the state through FISA order). If it's not that modern, a bad actor car mechanic can still copy the recordings from your car for fun and profit.
It's not that bad, unless it's a risk to your threat model (you're a journalist, whistle-blower or a famous millionaire).
