And terrible (non-)response from VECV, if they have any interest in receiving timely disclosure from future researchers.
reminder, these vendors like Volvo etc., don't really want you to report vulns, you should just sell them to a broker instead and get some actual money as well, it's a win win.
I don’t know why particularly here over elsewhere, but this thought really makes me feel disappointment in the whole chain of humans responsible for the cost optimization away of product integrity.<p>Though in this case, with all the tracking being thrown into newer cars, maybe a bit of a gap is a good thing for the future. Jailbreaking vehicles would be a cool thing to see become widespread.
reminder, Volvo is Chinese.
I should look into how this affects my 1981 Volvo 244
This is my primary concern with modern cars. You are at the complete merci of the security and correctness of the cloud management software for the correctly functioning of the car.<p>Wouldn’t it be better if your phone/devices would pair directly with the car, exchange keys, and have the company cloud only function as a proxy.<p>On holiday a guests BMW didn’t want to “start” anymore because it couldn’t phone home because of lack of phone reception. They had to contact the dealer at home and move heaven and earth to get some dealer code to allow the car to start again for a while. Why is this even allowed?
Agreed that it's absurd. Consumers continue to purchase cars that do this though. BMW doing this, having proprietary bolt heads, and the subscription heated seats fiasco from nearly a decade ago have made it clear that BMW is a make that will try to screw you at every turn, yet people continue to purchase them.<p>It's a shame. I will continue to purchase vehicles with as internet connected and touch screen features as possible. My 2025 Toyota has knobs and a physical key still. Terrified what will be left on the market when I have to get a new vehicle in (hopefully over) 15 years.
>On holiday a guests BMW didn’t want to “start” anymore because it couldn’t phone home because of lack of phone reception. They had to contact the dealer at home and move heaven and earth to get some dealer code to allow the car to start again for a while. Why is this even allowed?<p>Surely there's more to this story? AFAIK last time I heard about something like this, it was because the guy's car was parked 5 stories underground, and didn't carry his car keys, because he was using his phone to unlock all the time.
> last time I heard about something like this, it was because the guy's car was parked 5 stories underground, and didn't carry his car keys, because he was using his phone to unlock all the time<p>I hope you aren't suggesting that set of details makes this okay. I should be able to park in a faraday cage 2 miles underground and <i>still</i> start it the same as I can on the surface. Including with my phone, if it's equipped with phone-as-key.<p>The phone-as-key shouldn't only work when online and shouldn't require the car to be online, either. And this is a problem trivially solved with proper use of cryptography.<p>The reason for this is that if the car gives people the ability to start a trip with a phone, it's dangerous to assume they'll always carry a keyfob as a backup. Just like I don't carry two car keys.
>The reason for this is that if the car gives people the ability to start a trip with a phone, it's dangerous to assume they'll always carry a keyfob as a backup.<p>How's this any different than say, not bringing your wallet with you, because 95% of the time apple pay works, and then getting mad at the shop/credit card company/apple when the payment terminal randomly decides to not accept apple pay? Not to mention there are plenty of other ways a phone can fail. It can fall into a toilet, you can drop it and the screen cracks, etc. By not carrying the keys, you're rolling the dice every time.<p>>Just like I don't carry two car keys.<p>That all depends on your risk appetite. I normally wouldn't carry money in my socks, but if I'm in a foreign country I very well might. Likewise if I'm going on a road trip where I might be days away from home, I very well might bring a second key, in case i accidentally lock one in the car or whatever.
ApplePay doesn't communicate with Apple through your phone, it presents the card details as a contactless EMV transaction through the card reader, so it's pretty much spot on as an example of how this should work.<p>Just so you know, EMV can work entirely offline if you need it to, because the reader has the public keys that the card requires to authenticate and vice-versa. ApplePay uses the same NFC standard as regular EMV contactless cards to communicate, it just happens to be a powered microprocessor instead of a radio-powered microprocessor but that's about the only difference. The smart card standard is really old and covers the exact use case of "what happens if I need to use this thing without the Internet because the Internet wasn't ubiquitous when it was developed.
> How's this any different than say, not bringing your wallet with you, because 95% of the time apple pay works<p>Apple Pay involves at least a third party (your bank) as a part of its function. This entity has to be reachable.<p>Unlocking my car needs me, and my car.<p>> when the payment terminal randomly decides to not accept apple pay?<p>I would be justified in being mad if, randomly, my BMW car would decide to not accept a BMW key (virtualized or otherwise).<p>> Not to mention there are plenty of other ways a phone can fail.

> Apple Pay involves at least a third party (your bank) as a part of its function. This entity has to be reachable.<p>No it doesn't. It has to have a recent token, and if it does not it will contact your bank.
The point isn't that it's fine for smartphone car keys to randomly fail, it's that there's plenty of other reasons they can fail that you're already living on the edge if all you're carrying is your phone. Therefore the "it's dangerous to assume ..." claim doesn't hold.
Apple Pay even works if the phone/watch battery is "dead"
It's very different, because you aren't moving from car to car. You're using your car with your digital key. There is no expectation of things changing. Rightly so.
It doesn't; BMW use the CCC Digital Key standard for "Digital Key Plus" and there's no Internet required post provisioning. This story really reeks of misunderstanding or "needs more information" as for BMW especially, I don't see any scenario where this could have happened, regardless of physical or phone key use.
It's possible they were trying to do something like remote start, which (at least in my bmw) does use the godawful bmw online service. In the retelling, this might have expanded to "couldn't start the car."
My Tesla works like this. No internet connection needed, just Bluetooth.<p>I do keep a card key in my wallet just in case.
In this case it was with car keys and the valley where they are parked has no cell reception at all. Apparently they could still enter the car but not “start the engine”. They then managed to get a code from the dealer to unlock the car. I’m unsure whether it was a software bug relying on communication unnecessarily, a intended feature, or something like an alarm being triggered which triggered some fail safes.
How they will be able to block you from using your car when they deem that you should by a new one? Or how would they be able to make something a paid feature after you bought it?
You need to support these poor fellas
I just want the most basic, no-frills EV truck. I'd even pay a premium over what such a thing _should_ cost. I want no cloud connectivity _at all_ unless I add it myself in some way.

That is admirable, though of course it should be a legal standard, and there should also be legal standards for building features in a way that allows you to use them when your data collection is disabled.<p>Disabling data collection shouldn’t disable entire major features like lane centering and navigation. Even tech giant spyware companies like Google offer offline maps.
I believe that Tesla does, or did. I never disabled mine as I want the vehicle to improve on the roads that I frequent. And it has, noticeably so, in the four years I've owned the vehicle.
You can disable connectivity in any car by pulling fuses.

>modern cars<p>Tesla doesn't have this problem. It just works. No cloud needed, other than at the time of purchase.
There is security that protects users and then there is security theater that provides litigation protection for the company.<p>Sometimes overlapping, but they are not the same thing.
Both are important actually, the security theater often deter from trying because it could be too annoying, it's generally "free to do", along with additional obfuscation, it's useful too but does not replace proper security, but from experience, theater+obfuscation+security is greater security than just security.
