There are many places a person could put a device on the outside of my house that would be within 7m of my phone.So someone needs to have 2 devices, one within 7meters of my phone and the other a few meters from my car?
There is almost no time this can happen that I'm not actually standing near the car. Not at work, not at home, not parked out in the world.
I could see this maybe working in a really busy street with dozens of people around? But then you'd see someone loitering by your car as you lock it?
Or maybe someone in a car next to you when you park in a lot could pull this off?
I think that's exactly what would happen.So someone needs to have 2 devices, one within 7meters of my phone and the other a few meters from my car?

This is a relay attack, so while interesting the real-world risk is low. Basically the attacker has to have equipment close to the car AND close to your phone at the same time (within about 20 feet of each). They can't just walk up to any Tesla anywhere and unlock it. They MIGHT just be able to pull it off if you were at home with the car parked in the garage, but then they would also have to break into the garage, WHILE you were at home (with your phone).
Garage door openers are also vulnerable to relay attacks.This is a relay attack, so while interesting the real-world risk is low.

Easy scenario. Two person team at a grocery parking lot with EV chargers. You plug in to charge while you shop. One person follows you into the store with one device in a backpack. The other with the corresponding device just walks up to your Tesla, unplugs, and drives away.So someone needs to have 2 devices, one within 7meters of my phone and the other a few meters from my car?

.. and as soon as the car is parked and locked, the thieves cannot get into it and the owner and the police know where the car is. I don’t think they will last long. Not saying this isnt a nasty attack, but its practical use to thieves seems limited. I suspect its main use will be to steal items from the car, not the car itself.Easy scenario.

PIN to drive…

That’s crazy talk. The secret password is 1234. DuhI saw a YouTube (WhamBamTeslacam?) showing professional thieves using the relay method to steal Teslas parked outside a home. When done in the night, they have plenty of time to drive it elsewhere and disable tracking (pull the SIM card I believe).
So yeah I would use a PIN if the car cannot be secured at night. Just don't use "0000" lol
they could also show up with a flatbed and pull the car up on to it.
they could also disable LTE or shield it
they could wait for the unmanned valet stand to grab the keys/key cards etc etc etc
they could do a whole bunch of things...
The reality is that they probably won't - whereas I would be using pin to drive every. stinkin. time. I. drive. the. car.
I'd rather use the keycard
or not worry about it
ummmmm, I hope you keep it locked in a safe. Pretty dangerous. Smash and grab, now your gun is on the street, no bluetooth hack needed.and my 380 auto I keep in it
I used to install car alarms when I was in college. This guy with a turbo porsche had me install the best I could find. Three months later his car got stolen. The thieves drilled into the battery and drained it so it wouldnt sound or report lojack. Then they put the car on a flatbed and towed it off. If they want your car they will get it.
Did you read the paper linked in the article? The whole point of the attack is that it is based exactly on how BLE works. The NFC cards are something different, and the fob may also be some other sort of radio, too. Phone-as-key could be vulnerable to this sort of attack, but for the reasons outlined in the paper it would still take a pretty concerted effort to pull off.This isn't how the BLE or NFC system works. Has anyone had their R1T lifted by a crook using this method? I don;t think so.
