Hi. My school just started issuing devices last year, and they have this Lightspeed spyware on them. Last year I was able to remove it by booting into Linux from a flash drive and moving the files to a separate drive and then back at the end of the year. This year I have heard from sources that they have ways of detecting someone booting from Linux so I am hesitant to do that option. My only other idea is to buy an old laptop off eBay that looks like it and install Linux on it. I could probably get one for about 50€. Does anyone have any cheaper ideas?

Oh also talking to IT isn’t an option.

By my question I mean:
Any hardware is made by some other people. Any hardware is work under a firmware, made by other people.

All that is a) regulated by licenses b) never can be trusted fully to work as you think it should work. Even if it based on open source - due to the "problem of untampered compiler".

If you have no total control over your hardware, can you say you truly own it?
What percent of control is acceptable? How to measure it?

It depends how far down the rabbit hole you're willing to go.

Today you can make sure the source code is truly what you intend, by running Linux on PC and GrapheneOS on Android. You might not have the ability to audit those, but others (like me) do, and are doing so.

Whether you believe us or not is more philosophy - but join us in the rabbit hole and see what you find. You'll find detailed public technical discussions of security and privacy. You can find some of that for closed software and hardware too, but we can never do as good of a job in that discussion without the source code.

If you want open auditable hardware, you can stick to Raspberry Pi.

There's an open hardware project for phone too, but it's more of a proof-of-concept, today, as far as I understand.

If you want the TL;DR version of where I landed - I posted this from a Pixel running GrapheneOS.

Graphene on a pixel 5 here my brother

Exactly. There could not be true / full ownership of hardware.
And yet that's fine for me.

Now about that:

Today you can make sure the source code is truly what you intend, by running Linux on PC and GrapheneOS on Android. You might not have the ability to audit those, but others (like me) do, and are doing so.

Even in that case you can never be sure what a compiler did with the code. You can say: go look at the code of that compiler. But then how can I be sure it's code had been compiled without malicious modifications. And so on.

[–] MajorHavoc 1 points 1 year ago* (last edited 1 year ago)

You can compile your compiler from source.

Edit: Here's how: https://www.linuxfromscratch.org/

Edit 2: I know you can hear the rabbit hole calling to you. Join us. Follow the rabbit trail.

But seriously, it's cool, you're curious about it, and the pay from the jobs it leads to tends to be pretty great.

This reminds me of the times i and my friend had deep philospohical discussions... at 2am. During a weekend party, while drunk, in highschool.

Anyway, don't go down any rabbit holes in which you can't see the bottom. Walk away. While whistling, if it helps.

[–] [email protected] 1 points 1 year ago (1 children)

Yeah, I know dangers of it, so this question for me is purely theoretical.

[–] MasterBlaster 1 points 1 year ago* (last edited 1 year ago)

OK. So, what's the worst case if they "catch" you asserting your privacy rights?

Based on that you can decide if it is worth doing it.

As of August 2023, the best way to avoid the problem of

untampered compiler

AFAIK Is using an MNT Reform With GNU Guix as its OS, I really liked this article "The Full-Source Bootstrap: Building from source all the way down". This approach could, potentially, solve the problem of the untampered compiler. Damn, maybe it already does.

As for the MNT Reform, the only thing I'm not sure is open is the actual processor firmware, but the schematics for its usage are available and even the Wifi firmware is open, so there remains the problem of actually verifying the hardware you get is actually the hardware you ordered, but that is a bit more complicated I think.

To be sure you should build processor from a scratch and then write your own compiler directly in machine code.
