GrapheneOS attestation compatibility guide

Guide on using remote attestation in a way that's compatible with GrapheneOS.

cross-posted from: https://slrpnk.net/post/15995282

Real unfortunate news for GrapheneOS users as Revolut has decided to ban the use of ‘non-google’ approved OSes. This is currently being posted about and updated by GrahpeneOS over at Bluesky for those who want to follow it more closely.

Edit: had to change the title, originally it said Uber too but I cannot find back to the source of ether that’s true or not…

    I don’t think it’s a coincidence that the shittiest companies are those, who enforce Google’s broken and monopolistic “Play Integrity” API. Revolut has connections to Russia, McDonalds supports the Israeli genocide in Palestine and Authy has always just been a massive piece of shit, not even allowing users to export their TOTP seeds. These are three companies I would NEVER even consider using anyway.

    And “Play Integrity” API actually does NOTHING, absolutely NOTHING for your security as an end user.
    You use an outdated, unpatched Android version with multiple severe, publicly known exploits on an insecure device?
    Google doesn’t give a single fuck.
    You use the newest version of Android with all the patches applied on Google’s own hardware, with a locked boot loader and a hardened operating system?
    That’s not allowed by the “Play Integrity” API.
    It’s only purpose is to serve Google’s monopolistic business interests.

    Google has ruined Android by closing it up.

    EU needs to step in and force Google to open it up.

    While at it, go for Apple’s monopoly as well.

    Small OT: In the article it’s mentioned also the app “IO” (italian for the english word “I”). There are also other important italian apps not working without play services. The serious thing is that that apps are almost mandatory to do the ordinary public administration bureaucracy. We can say that the italian state forces its citizens to use a smartphone with Google Play Services installed. This is no sense.

    I swear I am so close to jumping into the void of mainline linux on phones.

    The only main issue is device drivers, but I would be fine happily extracting them from android or making new ones. Modern Android is a complete full stack POS.

    Seems like my time to move away from Authy. Any drop in alternative for iOS? Ideally I could export services and load them back, not manually adding/removing 1 by 1. Even if I can’t though, suggestion still welcomed.

        It’s only officially supported on google phones because sadly those are the only ones that are not modified to fuck which makes installing and supporting other OS’es way too much work.

        Giving google money once for a device is not a problem from a privacy or security standpoint.

          That’s correct, but not the reason grapheneOS chooses only pixel phones. It’s the level of hardware security features.

            Also unlockable and presumably has well working builds. It’s not just graphene, but just about every Android project it there that’s best supported on pixels. Other manufacturers have a crazy variety of locking schemes and required tools. Each one is a nightmare to support.

              For GrapheneOS, it’s primarily that it’s re-lockable. That’s why other unlockable phones aren’t supported.

              The GrapheneOS install process sets new OS signing keys so you can lock the phone again and get full verified boot. However, most manufacturers haven’t implemented this feature.

                What do you get, app/feature wise for verified boot vs. Play integrity app? Does it increase the amount of apps that work on it?

                  No, Play Integrity intentionally checks if it’s a Google-approved key. Android itself has an API to check verified boot and gives info on the signing key - most devs just want to know verified boot is working.

                  I feel Play Integrity has a short life ahead of if competition authorities realise how exactly it works. “Anti-competitive” is the first thing policy-minded folks think when I explain the API to them.

                  I would guess that it allows to detect tampering if you have to give your phone to the security officers and they do or don’t do something with it without you present. I heard of such occurrences on the border, but this happens in other places and countries, too. Not sure if locked bootloader would help, though

          In the EU almost every phone has an unlockable bootloader, there just isn’t any roms or custom recoveries for a lot of them.

          Wish they’d at least support Fairphone.

          If Graphene reached out to them I bet Fairphone would even actively work with them to make it an official OS option.

                Hypothetically the hardware could have been modified, but that would take some insane level of a determined attacker to be fabricating modified pixels just to sell them on the used market.

                  Yes, this would only be a concern for targeted attacks by state actors, in which case not even buying new would be safe.

                  Thinking about it, in such a scenario buying used may even be safer

                  It also comes with a hardware auditor, although you need another trusted graphene phone to use it. I don’t know about the details, but sounds very hard to mess with it.

              Shouldn’t trust anything then. They could intercept your new phone and modify it. They did it for switches. But your not worth it for “them”.

          Your options are:

          Apple phone

          Bloated android phone like Samsung etc.

          Chinese android phone (xiami etc)

          Google phone with Android

          Google phone with graphene. This still looks like the best of those options.

          Or no phone? I guess people are hardcore enough that will be the option.

          Edit: I stand corrected.

              All of these are insecure as hell. Linux phones especially https://madaidans-insecurities.github.io/linux-phones.html

              Fairphone also really fucked up: They signed their own OS with the publicly available (!) AOSP test signing keys. These guys really don’t know that they’re doing, and I would trust their hardware or software whatsoever. And no, installing a custom ROM doesn’t solve this. Considering how bad their security practices are, we genuinely have to assume that there are security issues with the device firmware as well.

              /e/OS is based on the already insecure LineageOS, and it weakens the security further, so it’s not a good option either.

              None of the options you mentioned can be compared to GrapheneOS. It’s currently the best option if you value your privacy and security. You don’t have to give Google money either, since you can just buy a used device, which is also cheaper and more environmentally friendly. Google also makes repairing their devices pretty easy for consumers and even works with iFixit. Here’s a Mastodon post I recently saw about that: https://social.linux.pizza/@midtsveen/113630773097519792

                An used Pixel, assuming I can find one in my country, still costs four (4) times what I need to shell out for a in-market Lineage compatible phone.

                Theoretical security is cute, but it has to be adjusted to practical feasibility. The most secure computer in the world is useless to you if you can’t boot it up.

                  Security-wise you’re better off using whatever OS comes with your device (as long as it gets updates) than downgrading to LineageOS. At least most smartphone vendors (except for Fairphone) manage to ship their Stock OS with a locked bootloader and somewhat working Verified Boot.

              I don’t think LOS has any privacy/security improvements over the stock android?

              (IIRC) it’s even worse than stock because you can’t lock the bootloader after installation.

              Though if your phone isn’t getting official updates, it’s probably safer with LOS.

            Xiaomi has the biggest custom ROM scene out there btw despite them trying their hardest to stop bootloader unlocking. You really don’t need to have a company supporting unlocking to make ROMs for them. If they outright block it then that’s an issue.

                My friend just got a new Xiaomi phone. He tried unlocking it a few days ago and got “try again in 168 hours”. That happened in Europe. It’s an absolute mess nowadays, I remember when they started blocking you from unlocking the bootloader. First you had to wait 24 hours, then 3 days, now it’s an entire week. You also need to make sure you’re logged into your Mi Account on both phone and PC and do even more weird fuckery to ensure the process actually go through. Meanwhile, on GOOGLE Pixel devices you just type one command after you enable oem unlocking in settings and reboot into fastboot mode. Crazy.
