Rent-seeking is the true American way, it seems. Good on the hackers. Good on everyone who helps to liberate us from the overreach of big business.

Is it rent seeking/overreach?

I make a video game and charge $50 for it. Later I make a DLC and charge $25 for it.

Is your claim that if I keep them as separate purchasable downloads, I'm not rent seeking?

But if instead combine the game and dlc into a single executable (to simplify build and distribution) and put the dlc behind a software lock, somehow that is now rent seeking/overreach and I deserve to have hackers unlock it for everyone for free?

That's likely because it's a hardware issue, nothing really for tesla to do.

Apologize for my ignorance, but isn't it up to Tesla to define what hardware they want to integrate? Or is there no design alternative?

But how much time until the hardware is changed? And all the current models?

Am I the only one who thinks it's incredibly irresponsible to disclose this without going through proper channels first? They claim this hack unlocks a host of other features. Seems like a great way to get a bunch of people messing with their cars which could lead to all kinds of catastrophic consequences.

Here's a question for the lawyers out there: if you notify Tesla that they're no longer authorized to access YOUR car, and they remote into it anyways, would that come under Computer Fraud and Abuse?

IANAL. It seems like it should probably be covered anyway, without the notification. Assumed consent would cover updates and improvements. No-one is consenting to their car being crippled, surely.

It gets me wondering how well Teslas will function with zero connectivity w/ Tesla. I mean, if the company goes under or (more likely) they drop support for older models, do older cars get bricked and disabled like clients for a multiplayer game that's gone offline?

> enable us to extract an otherwise vehicle-unique hardware-bound RSA key not ed25519? I know very little about these encryption thingies. The Internet recommends ed25519 over rsa.

They haven't broken the encryption technique, they've bypassed it by extracting the key using weaknesses in the hardware-software. You have to redo the process for each physical device to extract the particular key in use in that device.

From the perspective of a customer, what is the difference between a heated seat that doesn't work because it doesn't exist, and one that is locked out by software? Assuming the customer isn't paying up front for that feature. Some people don't want to pay for heated seats. Turns out the manufacturer found it cheaper to just include the hardware anyway rather than differentiate on the production line. What's the big…

>Some people don't want to pay for heated seats. Turns out the manufacturer found it cheaper to just include the hardware anyway rather than differentiate on the production line. If it's that cheap then it should just always be included, period. Otherwise it's just transparent greed. Why charge your customers extra for something that costs you literally nothing extra? Why not do the same for everything? The radio vol…

Stop giving them ideas!

Pretty sophisticated attack vector: low voltage attack on AMD secure execution environment during boot. I wonder how many tries you need to get whatever bits you need in the right place. Also, I imagine you only need to cut 12V wires to do this, but I admire the willingness to get in there direct on these systems. I'd be a little nervous to make those cuts personally. Buried in the article is the claim that this will…

> you could anonymize your location on Tesla's servers I already anonymise my location on Tesla's servers by simply not owning a Tesla

Your car is filmed and recognized by other teslas.

It's boggles the mind that a car company would spend millions on styling and then do something like that to completely cheapen the experience. Of course, software companies do that sort of thing all the time. Just...ugh.

$$$, that's why. $X isn't good enough for them, when they can find a way to get $X+Y
