What is the basis for this claim? I've never heard of this capability.
- arkadiyt 5mo agoIt's from the linked rav4world post
- venussnatch 5mo agoThere's no basis mentioned there either. It's just stated as a matter of fact without explanation.
- ezfe 5mo ago> One caveat, if you use bluetooth to connect your phone to the car DCM will use your phone to connect to the mother ship and presumably send your data. I only use my iPhone cable to connect to the car which does not have this effect. A random post on a forum is not evidence that Toyota has found a magic way to exfiltrate data over a bluetooth connection without turning on hotspot/etc.
- tadfisher 5mo agoIt's not evidence against it either. Presumably CarPlay and Android Auto could implement a network interface through the application layer, or even activate Bluetooth tethering at the system level as they are privileged apps. But they could also do this over USB, so something doesn't add up.
- throwway120385 5mo agoRNDIS was a mechanism for tethering over USB, and you could certainly pair "Bluetooth Network Adapters" for years and there's a profile for it. So there's at least precedent for it. That makes it pretty plausible to me.
- rightbyte 5mo agoIf the car manufacturer got control of an app on the phone it is trivial to exfiltrate data via Bluetooth.
