A group of researchers found a way to hack a Tesla's hardware with the goal of getting free in-car upgrades, such as heated rear seats.
The researchers will present their research next week at the Black Hat cybersecurity conference in Las Vegas.
Christian Werling, one of the three students at Technische Universität Berlin who conducted the research along with another independent researcher, said that their attack requires physical access to the car, but that’s exactly the scenario where their jailbreak would be useful.
“We are not the evil outsider, but we’re actually the insider, we own the car,” Werling told TechCrunch in an interview ahead of the conference. “And we don’t want to pay these $300 for the rear heated seats.”
The technique they used to jailbreak the Tesla is called voltage glitching. Werling explained that what they did was “fiddle around” with the supply voltage of the AMD processor that runs the infotainment system.
“If we do it at the right moment, we can trick the CPU into doing something else. It has a hiccup, skips an instruction and accepts our manipulated code. That’s basically what we do in a nutshell,” he said.
With the same technique, the researchers said they were also able to extract the encryption key used to authenticate the car to Tesla’s network. In theory, this would open the door for a series of other attacks, but the researchers said they still have to explore the possibilities in this scenario.
The researchers said they were also able to extract personal information from the car such as contacts, recent calendar appointments, call logs, locations the car visited, Wi-Fi passwords and session tokens from email accounts, among others. This is data that could be attractive to people who don’t own that particular car, but still have physical access to it.
Mitigating the hardware-based attack that the researchers achieved is not simple. In fact, the researchers said, Tesla would have to replace the hardware in question.
Tesla did not respond to a request for comment.
If I rent something then feel free to offer me upgrades to that rental (like rear heated seats) but if I purchased the product then fuck off its mine and I should be able to do what I want with all of its hardware.
I wish people would apply this logic to Apple aswell but they generally seem to let it slide because they like the company
With Apple, people generally let it slide because electronics aren’t as expensive and don’t last as long. Cars, on the other hand, are extraordinarily expensive and they’re supposed to last a lot longer than a phone.
Plus, at least Apple doesn’t (for example) charge you extra just to ‘unlock’ more performance on your phone.
Well that's the future they want anyway - for you to own nothing and be happy
You wouldn’t download rear-heated seats.
Just the entire car
So they install heated seats and then make you pay to unlock them?
That seems... not cost-effective
You don’t think they gift you heated seats do you? You pay for it, that’s part of the purchase price. They even save money because they don’t have to stock or install different types of seats.
Then you pay for it, and if you want to use it, you’ll pay for it again.
Welcome to the future. You’ll own nothing and you’ll be happy.
Paying for something in this era means they are still the product. Sometimes even more so, since paid options require signing into make use of the product creating nice account based activity to track with personal info and payment details. Future is awesome.
Actually, on that scale, it probably is more cost effective. They don't need separate factory lines, or to pump out cars with all sorts of different combinations of options. It takes better advantage of the economy of scale.
You'd be surprised. To make two different models, one without heated seats may very well cost more than just making one model with all the features built in. Now the cheaper version which normally wouldn't have these features at all actually does have them but they're disabled and that's why you paid less for it.
Tesla 85D and 100D both have the same battery pack too but on 85D it's digitally limited to smaller range and that's why it's cheaper.
I think that this kind of rentism has become dangerously pervasive, but I want to believe that more and more people are recognizing it as absurd. This kind of news does a lot to further this, imo.
Cost of equipment wasted vs cost of setting the plant up to make multiple option packages. Also, if you force someone to make a decision when they initially buy the vehicle, then you permanently never get that upgrade on that vehicle. However, if someone can chose later that they want heated seats then they might make the sale when the owner is sitting in their car on a cold winter morning freezing their butt off. Or, if the second owner wants it. All I'm saying is the cost of providing different manufacturing options vs the possible profits of someone purchasing it later, it is probably more profitable for them to do what they are doing. Otherwise they wouldn't be doing it.
Not just heated seats. Correct me if I'm wrong, but I believe Tesla only makes one of each model of car. So there's only one Model 3. Everything else that differentiates the trim levels is done entirely in software.
Think there's at least two frames, single and then for dual motor.
You’re wrong.
The 3 and Y have 3 trims currently, and had more in the past. They’re not software differences, they have different motors, different inverters, different chargers and different batteries.
The only thing that’s installed and not used is the heated rear seats, on the base model. Some people used to buy wiring mods online to enable them, and other people tweeted at Elon to make them available without a dodgy Chinese cable, so Tesla made it possible to enable them via software.
This isn’t something new it’s been around in the auto industry for decades, way back in the day you would have to run the wiring if a customer purchased a towing package, they changed that over time by basically having the wire harnesses pre wired and instead you would just add a couple of plug and play components, the newest versions of this is software unlocks, they just got rid of the actual hardware stuff
In this particular case I think this was a one off where they needed to make the car cheaper so that it was eligible for some rebate. To do that they took the model 3 they were already making, software locked the rear heated seats, some battery capacity, and maybe some other stuff, then sold the car for just under the limit. Then of course they added the option to pay to unlock these features.
As far as I know, they are not doing this kind of thing today besides unlocking some performance, but I could be wrong. Even with the performance I think the cost mostly covers the extra stress breaking stuff under warranty.
How long till Ol Musky sues them for some stupid reason?
TIL "Researchers" = Pirates. Sexy pirates.
As someone who owns one, this is excellent news!
I want to hack and jailbreak my car, and maybe put a better batter in a few years!
Companies of all kinds will always screw over the consumer.
I love the idea of some shady-ass looking garage with Cletus the slack jawed yokel charging Tesla owners for a good ole hackin’
You might be laughing at the fog, but you aren't far from the truth period take a moment to look into the John Deere hacker's period you have these rough black farmers learning how to hack their combined machines, so they can work on them without having to have proprietary software, it is quite interesting and amazing period
Borderlands vibes lol
Heated car seats is extra on Teslas??
That has to be the funniest thing I've read this week. What else is extra?
It's only one of the most expensive cars that exists, so naturally, charge extra for heating... :)
If I remember correctly, rear heated seats were only extra (and pre-installed just needing a software update to enable) once. There was a time when the cheapest model 3 was slightly too expensive for some rebates, so they sold a software locked version that was just barely was under the limit for the rebate. To reduce the initial price they software locked the rear heated seats, along with some battery capacity, and maybe one or two other things, all of which you could pay to unlock afterwards.
This is the best summary I could come up with:
A group of researchers said they have found a way to hack the hardware underpinning Tesla’s infotainment system, allowing them to get what normally would be paid upgrades — such as heated rear seats — for free.
This may also give owners the ability to enable the self-driving and navigation system in regions where it’s normally not available, the researchers told TechCrunch, though they admitted that they haven’t tested these capabilities yet, as that would require more reverse engineering.
“We are not the evil outsider, but we’re actually the insider, we own the car,” Werling told TechCrunch in an interview ahead of the conference.
Werling explained that what they did was “fiddle around” with the supply voltage of the AMD processor that runs the infotainment system.

This bot needs a conditional check implemented to count the number of lines in the original post's comment, then only post if the length is shorter than some arbitrary value or percentage of its own results.
Good bot?
