The iPhone 7 Has Arbitrary Software Locks That Prevent Repair (vice.com) 199

Jason Koebler, reporting for Motherboard: Apple has taken new and extreme measures to make the iPhone unrepairable. The company is now using software locks to prevent independent repair of specific parts of the phone. Specifically, the home buttons of the iPhone 7 and iPhone 7 Plus are not user replaceable, raising questions about both the future repairability of Apple products and the future of the thriving independent repair industry. The iPhone 7 home button will only work with the original home button that it was shipped with; if it breaks and needs to be replaced, a new one will only work if it is "recalibrated" in an Apple Store.

So while most people will not think twice about it and say "Fuck Apple.". No. Fuck you. Go buy an Android any ass-hat can repair then. I prefer my iPhone to be as secure as they can practically make it, while keeping it relatively functional.

        It's not secure from the Feds. They broke into that iPhone in Texas by compromising it and bypassing the encryption altogether. They also haven't released the details of how they did it. So your using security by obscurity instead of Android where everything is transparent. Might as well install windows on your phone instead.

    I hate to claim "it's not a bug, it's a feature" but this is done to make sure you cannot replace the home button with one that will send a "correct" signal for an incorrect fingerprint.

    Home buttons have been tied to the motherboard they shipped with as long as the iPhone has had fingerprint readers, this is not new.

      The difference is that in past iPhones you could replace it with a third party button, you lost TouchID and had to log in with a PIN but otherwise it worked. Now it's Apple's button or no button at all. Maybe they just decided it's safer for some reason or it's just a side effect of a design change or maybe they had second hand sales that were unhappy they got a "fake" home button. Whatever the reason my guess is Apple won't budge and you'll probably not win a law suit so... that happened.

      Actually, it does seem unreasonable. The proper behavior would be to detect the unknown reader and purge all fingerprints from the secure enclave, forcing the user to set up fingerprint recognition again after unlocking with the passcode. That would mean that the user would be alerted to the fact that the hardware was altered (thus preventing surreptitious swapping as a targeted attack) while still allowing the device to be repaired by swapping hardware at the user's request.

      The current situation is exactly the sort of behavior that got car manufacturers a very nice set of laws that mandate repair part availability, etc. Keep going down this path, and Apple will earn the consumer electronics industry a similar set of regulations, and none too soon.

      • by EndlessNameless ( 673105 ) on Friday April 07, 2017 @02:53PM (#54193413)

        The issue is that the fingerprint sensor is trusted to neither store fingerprint data nor replay finger presses.

        If you accept data from untrusted sensors, an attacker could replace the sensor with a device that will store valid finger scans and retransmit them when triggered by the attacker.

        So you need both trusted firmware and a secure pairing process to ensure the device is not compromised in this manner.

        While I suspect this move is mostly motivated by a desire to obstruct third-party repairs, there is also a legitimate security concern with this particular component.

          Then the proper behavior is to simply ignore the new fingerprint reader, and force the user to always use a passcode.
          • And this is exactly what happens. If you install a new home button, the fingerprint part stops working and it only works as a home button.

              No, it isn't. It disables more than just the fingerprint based Touch ID. From the article: "In the iPhone 7, both Touch ID and return-to-home functionality are locked by software if you replace the button." That is, it doesn't even function as a home button.

              Don't you feel ignorant now?
              • The iPhone 7 doesn't have the mechanical button any more. It's just the fingerprint reader. So if the fingerprint reader is locked out, so is the not-a-button that servers as a home button.

      • If you believe in security, this is a good thing

        I believe security should be optional to the end user, not something they are forced to pay when not needed. Sure flag up warnings and disable things like Apple Pay if the finger print reader has been tampered with. But some people actually use the device as a phone and a web browser, and really don't care about Apple's secure enclave.

    • Fingerprints are not the primary security on the device. "Recalibration" (pairing) should require no more than entering the PIN and/or logging into the associated iCloud account.

    ...and laws that establish fair-use guidelines for software that's required for hardware to function. Unfortunately this is something that would have to be grassroots and widespread, no one party would ever make any headway on this unless there were an outcry from constituents, and even then it would be hard to overcome corporate counter-push.

    We've seen this kind of problem with conventional cars and light trucks, with heavy trucks, with farm implements, with major consumer appliances, and the prolifieration of this mindset is only getting worse as more and more functions can be software-tied.

    The laws need to say that software bundled into the device is considered part of the device, and may not be used to encumber the right to service or repair the device, and that for such software that is also intended to communicate with other software, the vendor must continue to support and maintain that code for bugfixes and security vulnerabilities for the realistic lifespan of the device and must provide a reasonable means for the owner to install such an update.

    Yes, this would increase the cost of the device originally, as the concepts for update must be turned into an actual process, but on the other hand if that means that the device can function for longer then it's net effect on the consumer should be small as they can continue to service and repair devices for longer than if vendor-created blocks stop them from doing so.

    • Ahhh. You mean something like federal laws regarding the repair of your personal vehicle. Like, for example, the federal law that says you cannot replace a wheel on your vehicle with another one unless it has TPMS (tire pressure monitoring system) sensors in them compatible with the vehicle, and the sensors have been configured and interfaced with the vehicle's computer, which for many vehicles requires proprietary diagnostic hardware costing thousands of dollars. So in other words I can't undo 5 lug nuts

      • by bws111 ( 1216812 )

        The law does not say you can't replace a wheel without TPMS. It says you can't disable a safety system. In the case of TPMS, the 'safety' aspect is in the form of a warning to the driver that there is a problem - either tire pressure is low or there is a malfunction in the system. You can replace a wheel without TPMS, but you can not disable the malfunction indication because it is, in fact, malfunctioning.

    • Even more basic than that, what we need is to realize that the Fifth Amendment affirms the right to property and that any law that prohibits the owner from modifying his property -- such as the DMCA's anti-circumvention clause -- is therefore unconstitutional.

    As I understand it, this is a security measure, not an "arbitrary" lock. The home button is part of the Secure Enclave. If you let third parties make modifications to the Secure Enclave, it ceases to be secure.

The problem lies in disabling the return to home functionality. As long as I am ok with not having Touch ID available why shouldn't I be able to replace the home button?

    I'll give people the benefit of doubt, but it sounds like a whole ton of commenters here are going on with guesswork.

    First of all, no, it's not easy in any way shape or form to create a rogue touch ID reader that would "send signals" allowing the iPhone 7 to be unlocked.
    It'd already be plenty hard for someone to open up a phone and replace it surreptiously, let alone coming up with new hardware that would be compatible.

    Do you guys even know how the TouchID reader works? Well, neither do I of course... it's proprietary. But here's an overview:
    http://edition.cnn.com/2013/12... [cnn.com]
    http://edition.cnn.com/2013/09... [cnn.com]
    https://support.apple.com/en-u... [apple.com]

    Basically, it works like a very specific and proprietary camera/microscope. It detects fine detailed fingerprint information, converts it into code and sends it to the SoC to be processed via software.
    Nothing is processed on the button itself, and even if it was, you wouldn't be able to easily figure out what it did - or it'd be unsecure by definition.

    But again, the hardware is very proprietary. You'd probably need insider knowledge of production to even come close to making something that would work like it, and it'd be expensive as hell to reproduce one. The companies that makes these things have secretive processes that not only would be incredibly hard to figure out, it'd be outright impossible to reproduce without proper technologies.

    Do people even realize how much easier it'd be to just chop up someone's finger and bypass the whole thing anyways?

    Even if you couldn't go to such extremes, it'd be easier for hackers and malicious actors to try to reproduce an entire detailed human finger complete with ridges, pores and whatnot (at it's current stage) than creating some rogue device that could bypass the security enclave somehow.
    And you cannot retrieve information from previous fingerprints used for authentication because they are encrypted in the phone storage, not in the reader.

    The only likely scenario where Touch ID could be used to steal fingerprints, depending a lot on how it works, would be to use an original unit modified to store readouts, and then creating new hardware that would send those into the system. But that's quite unlikely... if not outright impossible. Again, it depends on how exactly the reader works. Note though how no one every did anything like this, because it just doesn't make sense. iPhones will always have easier vulnerabilities to explore to retrieve data.

    It's always good to note though that fingerprint sensors should NEVER be used as the sole authentication method if you have sensitive information inside the phone. Because, like I said, it's a matter of finding a way to make a very detailed reproduction of your finger. With 3D print technology and camera technology always improving, it'll be doable at some point in time.
    It was already done for the iPhone 6, though not something that just anyone could do:

The phone could still be locked and unlocked as normal by entering a pin number, suggesting that the two functions are separate pieces of software that are not tied together.

    The first concern I had was whether the entire button would refuse to work, and that would be bad. If only the security features are disabled, and there are alternate ways to log in, this sounds perfectly reasonable.
