I’m lucky my banking app works (GrapheneOS), as it’s now requiring 2FA with the app anytime I login on the browser. Can’t use an actually secure form like TOTP. At least they now allow passwords over 8 characters (yes, serious).

    Are you 100% certain they don’t just truncate your password to 8 characters?

      I’ve seen a website that silently truncated my password during a password reset, but then wouldn’t truncate it during login. It took me a while to figure out why my password never worked.

      What, do you think banks have the money for storing all those extra unnecessary characters? MS Access databases are only so powerful.

        Never ever ever store passwords in the database. Salted hash only. It’s fixed length even if the password is a gigabyte long.

      Your bank are allowing you to use characters ? Mine only allows numbers for the password, it has to be 8 number, no less, no more.

          thats fair. device support is a major downside of GOS. but, remember: its not really the fault of the OS, as it requires a lockable/unlockable bootloader, which only pixel phones provide (at least in terms of mainstream phones). blame the OEMs like samsung

                  That’s the main issue really, as it open the possibility to manage your device for anyone getting hold of it. Probably some debug attack methods also with it.

            Mainstream phones? Pixel is a smaller market share than Motorola, and Motorola has unlockable bootloaders, and lineage supports a fair number of them.

            Only big manufacturers can really pay to control entirely the hardware inside it, and allow you to modify it. Checkout Fairphone for example. They’ve been forced to stop hardware security updates due to their chip manufacturer, who refused to continue supporting it, despite them trying to support their devices for plenty more years. This explains the choice with Google.

        What are the security issues? Rooted just means the potential to give trusted apps root access. Of course, if you give an app root access that you trust but is then abusing that trust and being malicious, yes it’s a security issue. But if you don’t do that, the simple fact of having a rooted phone should have no security change in any way. (Ok, except for potential bugs in Magisk/su or whatever)

          The whole issue revolves around the fact Google is presuming a device is compromised or being used for illicit shit simply because root access is possible. If they put in effort to detect/prevent the actual problems they’re concerned about, this wouldn’t be as big a deal. This broad punishment for simply having root access is lazy and ridiculous.

          It’s like if Windows apps just stopped working if they detected a local admin account. It’s patently absurd to assume the ability to access anything means the device is inherently “unsafe”.

          If you have the UI layer able to grant root access, it has root access itself and is not sandboxed. If the UI layer can grant it, an attacker gaining slight control over it has root access. An accessibility service trivially has root access. A keyboard can probably get root access, and so on. Instead of a tiny little portion of the OS having root access, a massive portion of it does.

          In the verified boot threat model, an attacker controls persistent state. If you have persistent root access as a possibility then verified boot doesn’t work since persistent state is entirely trusted.

          A userdebug build of AOSP or GrapheneOS has a su binary and an adb root command providing root access via the Android Debug Bridge via physical access using USB. This does still significantly reduce security, particularly since ADB has a network mode that can be enabled. Most of the security model is still intact. This is not what people are referring to when they talk about rooting on Android, they are referring to granting root access to apps via the UI not using it via a shell.

              The actual Magisk prompt that ask you if you want to give root to such app. This UI layer.

              Although, i suppose it could be countered by explicitly refusing all requests or enabling a biometric confirmation

                But granting root is not done by “the UI layer”, “the UI layer” is not running with root. There is no such thing as “the UI layer” as a separate entity, an app can have a UI layer as part of its architecture, but the UI is not running on its own. Just because Magisk shows you a UI for you to grant/deny a root request, that doesn’t make it insecure. Nothing is able to interact with this prompt except the Android kernel/libraries itself and Magisk.

                Only if you added an application as accessibility tool (or give it root) can it interact with anything within the UI. An app with a UI is generally not much different than an app on the command line.

                  It still create an attack vector, as it allows a potential extra method to get access to it, in addition of potential hardware exploits that i shared to gain root. Yes, you can minimize the risks correctly, but the user is the only real barrier against it, not the software anymore. The less potential way to exploit your phone, the better it is. You shouldn’t rely on thinking that such feature is fully attack-proof.

        Can you compile your own OS from source for an iPhone and install it yourself? I don’t think so.

        I have done that with my non-rooted android, and I can do anything I want with my phones through the powers of open source software.

        Rooting is unnecessary now and that’s a good thing.

          You can’t do that without unlocking the bootloader, and that alone will trip “root detection” (Play Integrity).

          Some apps take it further and won’t run if you enable Developer Options! (Or have any number of “hacking apps” installed, such as autotap apps that don’t even need root.)

              If they work with an unlocked bootloader then they would almost certainly also work fully rooted, with the advantages that brings (such as actual working app+data backups, limiting max battery charge, better automation possibilities with apps like Tasker, etc)

              I’d much rather switch banks than give up rooting my phone.

            Well you can, and there is no punishment, so you should be happy.

            I imagine you probably think “punishment” is that some bank won’t let you use their app on a rooted phone. That is not a punishment, that’s the bank implementing the security that they deem necessary for access to their software, and is likely part of a license agreement that you agreed to by using it. You have no default entitlement to have free use of the software that anyone else produces unless the software developer’s license states that you do.

            Actual punishment would be if your phone gets bricked by the OEM for rooting it, or government authorities fine or arrest you for rooting.

          Rooting is always necessary, you can’t convince me otherwise, imagine not having root permissions in your Windows, Linux or macOS machine…

          Without “rooting” capabilities we wouldn’t have custom firmware for tech that is quite locked (like the PSP, Vita, 3DS and whatever OS they use), emulation would not be the same.

          Heck, even some iOS versions can be jailbroken yet, I cannot conceive a world where iOS is less locked than Android.

            You are being downvoted because you’re factually wrong. While Android (especially on Samsung devices) had been getting more locked down over the years, even unrooted it has way more freedom than an iPhone. For instance, you can install any number of APKs, without jumping through any hoops.

              For now. Google’s recent patterns would seem to indicate the future trajectory of Android to become even more hobbled.

              I doubt it will ever be as closed as iPhone but there’s a point where the door is technically still open, just not in a way that really means much.

      And they all develop their own shitty app for 2FA (the lazy ones just rebrand SecureGo as their own - you still have to install all of them separately) instead of using the 15 year old TOTP standard. The latter is good enough for tiny companies like Google and Amazon but what do they know about itsec, right?

      The hardware attestation feature is part of the Android Open Source Project and is fully supported by GrapheneOS. SafetyNet attestation chooses to use it to enforce using Google certified operating systems. However, app developers can use it directly and permit other properly signed operating systems upholding the security model. […] Direct use of the hardware attestation API provides much higher assurance than using SafetyNet so these apps have nothing to lose by using a more meaningful API and supporting a more secure OS.

      https://grapheneos.org/usage#banking-apps

      My banking apps work on GrapheneOS, so I guess they are using hardware attestation instead of SafetyNet. LineageOS won’t pass hardware attestation because it doesn’t support locked bootloader.

          Ah, then there could be a different issue with my banking app. Maybe there’s a hope I can solve it then. I just assumed it the custom ROM that was the issue. Then again, maybe they just don’t bother letting me know the reason… :)

            It used to be possible (probably still is) to use magisk to get around it for my bank, but I stopped caring after the EU did some laws forcing interoperability between banks so I can just use my other banks app to access the accounts for that bank.

            Might be worth looking into!

      LineageOS doesn’t spoof safetynet and play integrity, GrapheneOS does afaik. So that’s most likely the reason

      See below

        GrapheneOS doesn’t either. It does Android Hardware Attestation instead of SafetyNet. It has never, and will never spoof SafetyNet.

    With the PNC bank I use, about 12 years ago, passwords used to be case insensitive, and they would allow ridiculously insecure passwords without complaining, like one123. I had a ridiculous password like that for a while because it was funny, then realized I’d be the one to pay for it.

    I didn’t try a rooted phone, but thankfully my banking app did work on my phone with custom ROM without SafetyNet.

    But they do block some VPNs. I know it temporarily didn’t work with ProtonVPN, though now it does again. They only told me that they allow VPNs which they consider secure, but for security purposes they won’t reveal how those considerations are done.
    How would that make it insecure, if they aren’t just using pre-made IP blocklists?
    Anyway, that was a painful experience.
    Getting it to work after being to connected to VPN required de-activation and re-activation of the app. That’s a fairly painful process since it uses OTP tokens generated by a card reader:

    It does have a digital version, but that’s less secure.

    Banks do this because most people don’t know how to use technology and it’s a lot easier to get remote access and malware on your computer than your phone.

      Funnily enough I had issues with Wallet working on my phone since I have unlocked bootloader but no root. Banking and everything else afaik worked. So I installed all that stuff, Magisk, Magisk Hide, I don’t even remember all the things I tried and what it resulted in was now since I was actually rooted all the banking apps and other stuff stopped working.

        When you root, you’re creating more flags for apps to detect, so you have to put in more effort to hide them all. That means a greater likelihood of something being detected if you missed it. It’s a trade off. You do have to learn a bit about what you’re doing and do some trial and error.

        But the greater point is, if banking apps and wallet are important to you on that specific phone, you can either root and put in the effort to make it work, root and just do all that stuff from a browser, or not root at all.

        Yeah, it’s annoying, but it isn’t the fault of Magisk or the rooting community, it’s Google and your banks fault for actively punishing you for using your own device the way you like.

        Personally, I have two phones now. My main one is rooted, and if I need an app that breaks on root, I pull out the “clean” one (my old phone after factory reset). Use a hotspot if mobile.

          For me it’s important that my banking works (so far they haven’t complained about unlocked bootloader, only about root) but Wallet is just nice to have. And that doesn’t work with unlocked bootloader but did work with root. I guess it’s no root for me since I haven’t managed to juggle them both.

          Sucks that Google is doing this. I don’t even have root and they are complaining. Makes having a custom rom annoying sometimes.

    Even worse still: many online banking services require you to connect to Google, basically through the back end captcha system. You never have to solve the puzzle or click on traffic lights, but they do still associate you and your web browser with having an account with that bank.

    However also, you can often use root with banking apps, you just have to set it up right. Configure Magisk to operate in the Zygisk domain with a deny list, and add the apps to that.

    My credit union’s web site looks like a MySpace page. They don’t even offer freaking 2FA. Been meaning to transition to cash management account but such a PITA.

      I have an account with a larger credit union and their Android app implements onerous rules which some exec must feel makes it more secure, but is just a burden 99.999% of the time. Today I found that the fingerprint login expires after a week of not logging in, requiring the username/password to log in. Annoying but ok, I log in with a username and password. Then it says I need to do MFA and presents 3 options, email, SMS, and app push notification. The UI for app push notification even says “This device”. I selected that one, and the app shows the approve/deny button over the MFA requirement screen.

      So obviously the saved state in the app wasn’t actually expired, since it could still approve MFA requests. So what good is it expiring biometric auth if the app is still authorized to log me in effectively bypassing MFA?

    Doesn’t work because of Play Integrity API but there are ways to bypass it. At least for now. Look up PlayIntegrityFork.

      Some apps implement other checks. Mine checks whatever you replaced the stock webview (checking the package name). So sometimes it is challenging to find those checks to bypass them.
