How hard would it be for a skilled person to disconnect the antenna/com-module (or disrupt connection in general) in a way that still allows for updates of the software, if I chose to install them?
You may be able to disable the antenna or SIM/cellular device, that wouldn't be too hard, but to receive updates you would need to reconnect them, and who knows how much data the car stores while it has no connection?
I assume you can't just download updates on your PC and install them manually on your car.
I mean, if you go to the shop, that’s what they’d do, right? I doubt they’re burning EEPROMs or anything more advanced than a custom connector.
When you go to a shop chances are their scan tool is connected to the internet and has the ability to download data.
Which means you should be able to, too - right? Might take a 1337 h4x0r to figure it out first, but then - pirate cars. Yarr.
Lol. Yeah. Maybe. But maybe you end up bricking your ECM or TCM and then your car won't start.
And if you can do it, so can the guy who wants to rip out your headlight and jack in to steal it.
Hasn’t that always been the case?
To some extent probably. But we have AI LLM'S now and more technology in our pockets than ever before. There's a reason there was so much hubabaloo over the flipper zero a few years ago.
And upload all your data..
That's what I'm hoping for. Also I might judt leave it disconnected. If there is no connection, the software also doesn't need security updates.
In the United States, that’s 5 years in prison. Because it’s done with computer. Computer rules strict, so make everything computer.
