Blue car in the background is a facelifted fifth gen RAV4. Obvious from the shape of the mirrors and headlight. Toyota/Lexus would align with the "both brands" remark.

White one is harder to tell obviously, but the shape of the mirror looks the same, and you can see the top of the dash has a chamfered shape that looks an awful lot like this pic: https://media.ed.edmunds-media.com/toyota/rav4/2022/oem/2022...

Posting a video demo probably isn't a great idea for this kind of thing. I'm sure some sicko could have figured this out just from the sound the locks make.

These always connected cars will soon become as bad, or likely worse, than the smartphones of today, which we don't really own and control, and always tracked.

You will need an online account with obscure terms of service to use the car, won't be able to repair yourself, your data being sold, etc.

Evil.

“Any car” is perhaps too strong a claim. If it is Toyota/Lexus, I will say that I don’t think my 2009 Camry has this issue. I am quite sure that the fourth-generation Hilux my brother has does not.

The follow up/linked article at the bottom is worth a read too as it's the 'world-wide' part of it. Definitely a great read from both Sam and Shubs

Warning: The video in the article contains VERY loud bleeps.

Just go wrench on your own car, like OP. You'll be amazed at all the funky ways you can gain access without a key. Not really secure, but difficult enough to prevent the casual shenanigans. This stuff predates the automotive IoT crisis too.

Any lock can be picked. The article is an interesting read and the author found some obvious mistakes the company should not have made, but if it's a hack that takes weeks and multiple people to pull off, I wouldn't be too worried as an owner. Back in the non-nerd world of common criminals, some guy with a Stone Age brain simply smashes your window to grab whatever he can. Also take a look at how easily a professional could gain access to your home if they wanted to.

I think automaker failed security the moment its cars connected to the internet

Why GPT-5.6? Was this done before the release of GPT-6, or is there some difference in restrictions between the two?

For anyone who is trying to decipher the clunky title, it means "Unlocking vehicles from a major manufacturer, across the globe" The manufacturer is not disclosed.

The byline says “security researcher”, but I didn’t find any mention of disclosure to the platform security team in the blog post. What gives?

I'm glad I bought a Corolla LE that does NOT have remote start. I still have to insert the key to start the engine. So much more secure.

Imagine what K.A.R.R could do with that.

And this, kids, is why we're not getting a "connected" car.

It's extremely difficult to find, hire, and then put into the right position a competent security engineer. Meanwhile competent hackers grow on trees. I understand that mistakes here were silly, but that's not the point. The point is, security is fucking difficult.

IMO the practical solution to this problem - because telling companies "just do security better" works as much as telling fat people "just eat less" - would be some kind of central registry of car parts. This was already implemented in iPhones back in the day that if a repair wasn't signed off by Apple, you couldn't install a new part to your iPhone. I imagine that if the government had a similar thing but for cars, then thieves would stop stealing cars because each stolen part would eventually be flagged somewhere and the end customer would be upset, never coming back.

I say "government" because companies cannot be trusted to make a simple interface "log in -> enter part number and car license plate -> ready to install". I assume that outside of the US the "log into government website" part is already solved in one way or another. On the privacy side, it really shouldn't be controversial, assuming that people are already used to the VIN having a repair history tied to it.
