I know this is going to come across when you first read it as "This is one of those tin foil hat dudes... (skip to next message). First, I want to say I am not "one of those dudes;" I just know what is out there regarding remote execution vulnerabilities and the prices paid for them.
I have been considering the Apple Watch 5 with Cellular to replace my Apple Watch Series 0. I am going to have to replace my iPhone X due to cracked front and rear screen, and it is not much more to get a replacement as Apple states they cannot replace the front screen if the black glass is damaged due to the damage on the back of the phone will only get much worse when they perform the process of removing the front screen to replace it (apparently it puts a certain amount of stress on the phone and could cause a crack in the glass on the rear panel to break in two). So right now, I have no viable option, and am considering the iPhone 11. I wouldn't be doing that if I had not damaged the X as I keep a phone as long as it will work, however unfortunately for the X and it sliding off things often that wasn't long. I like carrying the phone naked, but lesson learned and will deal with a protective case 🙂
Anyway, since the Watch + Cellular will be on or near you 24/7, how many think it could be compromised and turned into a hot mic like has been proven on iOS and Android in the past? I suspect it has a minimalistic OS so that would lower the attack surface, but if connected to the cellular network 24/7 and it as compromised, I could picture it easily being used as an eavesdropping device. Although I have not verified, I suspect there is a way to turn off the cellular radio with a toggle to save battery life?
I have nearly made up my mind to purchase one anyway, but was wondering what others thoughts are, if any, on this topic?
Thanks!
