Cops Can Bypass iPhone’s Automatic Reboot to Get Into Locked Phones, Leaked Video Claims

A company that makes phone hacking devices claims to have developed a solution that freezes iPhones in a state that lets cops more easily access sensitive data inside them, according to a video obtained by 404 Media.

This is the latest salvo in the never-ending battle between Apple and companies that help cops — sometimes those in authoritarian countries — break into iPhones.

In November 2024, 404 Media revealed Apple quietly introduced a new feature in iOS that automatically reboots an iPhone that has not been unlocked for 72 hours. The idea behind this so-called “inactivity reboot” is to revert the phone to a state that makes it harder for police to break into the device, and thus extract sensitive data from it with forensics technology.

At the time of Apple’s change, law enforcement agents expressed concern about this new feature, given that oftentimes they can’t immediately try to break into iPhones that have been seized. That could be because police are still waiting for a court authorization to do so, or there is simply a backlog of devices to unlock, for example.

Genuine question here. I don’t really get the idea of using print and then a pin. If I want more security, then I use the pin alone, if I want more convenience, then I use a print. Can someone please give me an example in which using both actually makes sense? I honestly don’t see how using both would benefit security, it certainly does not benefit convenience.

I can see the use of 2 factor with a PIN and then a hardware key like a yubikey, or a pin and then a password, that does make sense to me, focused on security alone and doing away with convenience.

The benefit is if your PIN was compromised your phone would still be inaccessible, barring them having you physically. It’s another layer of defense. Similar to a yubikey, if someone had your phone but not the extra hardware. Although I think using a yubikey every time I wanted to use my phone would be prohibitively inconvenient.

Also, I don’t think PIN and password would be considered 2 Factor. That’s essentially just a longer password.

On Graphene, Lockdown mode disables biometric login until you unlock it manually with your passcode, but the device is still in the less secure AFU (After First Unlock) state.

You can also set it to restart the device if not used within a set time period. Various settings from 10 minutes to 72 hours. So if you haven’t touched your device within that time period, it will shutdown and restart, going back to the more secure BFU (Before First Unlock) state.

It’s almost like there’s only two ways to actually accomplish this type of thing. You can do the same basic thing but use different names to differentiate where/how that function is used.

Lock it and require the passcode where the decryption key is still in memory because the system is running, or shutdown/restart the device so the decryption key isn’t in memory anymore.

What would a third option even look like?

Are you. Understanding a standard shut down does what you want?

What are you babbling about? Of course, that’s why I already said it. Twice.

Both comments I have made in thi thread have mentioned shutting down or restarting the device to put it back into a BFU state.

Since you clearly didn’t actually read the comments you are replying to… I’ll include the relevant parts from both below:

You can also set it to restart the device if not used within a set time period. Various settings from 10 minutes to 72 hours. So if you haven’t touched your device within that time period, it will shutdown and restart, going back to the more secure BFU (Before First Unlock) state.

You still didn’t answer the question I posed though… before replying in way that seems to indicate you either can’t, or refuse to actually read before responding condescendingly.

Since you seem to think there should be another choice instead of doing the same two things to protect the device/data… what would a third option look like? Other than locking and disabling biometrics, or a shutdown/restart putting the device back into BFU mode.

Or are you just stuck thinking a shutdown and reboot are technically different things? Even though that makes no difference here since they both put a device into BFU.

Most of these exploits involve side channel attacks which are much closer to the hardware. Graphene definitely does a lot more to make that difficult, but typically devices are getting pwned within a few months even with graphene.

Having graphene on relatively new hardware is a really good practice, but it obviously isn’t a complete security posture on its own. Not having sensitive, compromising or incriminating stuff on your daily carry phone is much more important.
