That would be called Security Through Obscurity. You can't lock something down if you put an example in each customer's hand.

OTOH the Tesla backend is running the Dojo chip, or will be soon. Reverse engineer that.

Modern cars are more computerized than ever. Infotainment and navigation systems, Wi-Fi, automatic software updates, and other innovations aim to make driving more *convenient. But vehicle technologies haven’t kept pace with today’s more hostile security environment, leaving *millions vulnerable to attack.

The Car Hacker’s Handbook will give you a deeper understanding of the computer systems and embedded software in modern *vehicles. It begins by examining vulnerabilities and providing detailed explanations of communications over the CAN bus and *between devices and systems.

Then, once you have an understanding of a *vehicle’s communication network, you’ll learn how to *intercept data and perform specific hacks to track vehicles, unlock doors, glitch engines, flood communication, and more. With a focus on low-cost, open source hacking tools such as Metasploit, Wireshark, Kayak, can-utils, and *ChipWhisperer, The Car Hacker’s Handbook will show you how to:
Build an accurate threat model for your vehicle
Reverse engineer the CAN bus to fake engine signals
Exploit vulnerabilities in diagnostic and data-logging systems
Hack the ECU and other firmware and embedded systems
Feed exploits through infotainment and vehicle-to-vehicle communication systems
Override factory settings with performance-tuning techniques
Build physical and virtual test benches to try out exploits safely
If you’re curious about automotive security and have the urge to hack a two-ton computer, make The Car Hacker’s Handbook your first stop.

Well, if you look at computers, which cars kind of are, there's a trend to go from "security from obscurity" to full blown locks and encryption.

Take a look at how Microsoft is pushing for all Windows 11 computers to have a Trusted Platform Module (TPM, not to be confused with Tire Pressure Monitor) version 2.0 or newer with secure boot. If they can encrypt hard drives and everything else with secret keys then it becomes a lot harder to hack computers.

The same with cars. If the tele data isn't so already, it will be soon encrypted. I'm sure CAN bus and all that is going to go the same route too if it hasn't. Soon sensors will have encryption chips and send encrypted digital data instead of analog voltage signals like they do now.

I used to live in that world. The Clipper chip and the UEFI bootloader.

I could edit the (Mac) boot blocks with Norton Disk Editor but Symantec never ported it to OSX. Nowadays if I forget the password I'm toast.

What's you favorite flavor of Linux?

Right now I don't have any use for Linux. Very few of the apps I use exist or have suitable alternatives on Linux. This is the same reason I don't consider using MacOS, iOS, iPadOS or a Chromebook. I only use Android for convenience and one other app.

I actually do have one laptop running Linux right now that I picked up for free that I'm thinking of installing Windows XP on it.

Getting back on topic, sort of, the reason I would want to run Windows XP on an old laptop is to run a hacked version of TIS, Toyota's OBD program, so that I can do things to my car like change the TPMS codes or bleed my brakes. I'm still up in the air if I should do that or not...

Yes it is.

That is very odd as ABS is decades old now and the tools are cheap.

So it must have been something else I had asked that they couldn't do. But now I'm not sure what it was or for what vehicle, or if the vehicle was even mine...

Anywho, I went ahead and called them up again today and they said they could do it. I got it scheduled to have the brake fluid flushed on the 27th. I'll let you know how it goes.

I'm not so keen on OTA updates, at all.
