Apple quietly introduced code into iOS 18.1 which reboots the device if it has not been unlocked for a period of time, reverting it to a state which improves the security of iPhones overall and is making it harder for police to break into the devices, according to multiple iPhone security experts. 

On Thursday, 404 Media reported that law enforcement officials were freaking out that iPhones which had been stored for examination were mysteriously rebooting themselves. At the time the cause was unclear, with the officials only able to speculate why they were being locked out of the devices. Now a day later, the potential reason why is coming into view.

“Apple indeed added a feature called ‘inactivity reboot’ in iOS 18.1.,” Dr.-Ing. Jiska Classen, a research group leader at the Hasso Plattner Institute, tweeted after 404 Media published on Thursday along with screenshots that they presented as the relevant pieces of code.

Does anybody know if LineageOS has an equivalent feature?

[–] NateNate60@lemmy.world 320 points 1 week ago (23 children)

Law enforcement shouldn't be able to get into someone's mobile phone without a warrant anyway. All this change does is frustrate attempts by police to evade going through the proper legal procedures and abridging the rights of the accused.

[–] extremeboredom@lemmy.world 122 points 1 week ago

Yep! The police, being fascists, HATE this.

[–] ohellidk@sh.itjust.works 44 points 1 week ago* (last edited 1 week ago) (12 children)

well it's kind of a selling point. I'm just too used to using android, though.

Edit - there's something for that too, cool!

[–] NikkiDimes@lemmy.world 51 points 1 week ago (2 children)

You can enable lockdown mode. It forces the next unlock to ignore biometrics and require a pin, which police cannot force you to divulge without a warrant. Once enabled, you get a "lockdown mode" option in the menu when you hold down your power button.

[–] gamermanh@lemmy.dbzer0.com 22 points 1 week ago (9 children)

If you haven't done this and need the same ability IMMEDIATELY: reboot, or just shut down

Every first boot requires pin same as lockdown

Also: set a nonstandard finger in a weird way as your finger unlock if you wanna use that, then theyre likely to fail to get that to work should you not manage to lock it down beforehand

Finally: there are apps that let you use alternate codes/finger unlocks to wipe/encrypt/reboot the device instead, allowing you to pretend to cooperate with the cops up until they realize they got played

You can use GrapheneOS, a security-focused version of Android which includes auto-reboot, timers that automatically turn off Wi-Fi and Bluetooth after you don't use them for a certain period of time, a duress PIN/Password that wipes all the data from your device after it's entered, as well as many other incredibly useful features.

It's fully hardened from the ground up, including the Linux kernel, C library, memory allocator, SELinux policies, default firewall rules, and other vital system components.

IT support everywhere sigh in satisfaction

[–] iturnedintoanewt@lemm.ee 116 points 1 week ago (14 children)

GrapheneOS also has this. Not sure stock android includes it.

[–] catloaf@lemm.ee 58 points 1 week ago (2 children)

It does not. I don't have it on my Pixel 6. From other people's comments, it sounds like Samsung and other OEMs have added their version, though.

[–] darkevilmac@lemmy.zip 22 points 1 week ago (7 children)

Yeah, can confirm Samsung has this. I have auto reboot configured.

That seals the deal for me on rooting my pixel. I've been hesitant about rooting ever since I bricked an extra galaxy s3 and nearly bricked my (main device) Verizon galaxy s5

If you have a factory pixel, you don't need to root. You can unlock bootloader and install a rom that has it (calyxos or grapheneos I know have them). You can root, but you don't have to.

GrapheneOS been had this feature, don't let apple tell you they invented it.

[–] thisphuckinguy@lemmy.world 76 points 1 week ago (1 children)

Great software features should be available to all hardware, regardless of OS.

[–] ArcaneSlime@lemmy.dbzer0.com 47 points 1 week ago (3 children)

For sure I'm just joking about apple's habit of taking a feature that has been around for YEARS and claiming they "innovated" it, usually after they strip it down a little no less (like in this case where it appears to be a setting users can't access, but Graphene lets you turn it on/off or adjust the time between lock and reset.)

IMHO, the novelty of the feature isn't what makes this headline worthy. This is noteworthy because of the scale. iOS is over a quarter of phones on earth, and in English speaking countries and Japan, you're looking at numbers that are often over 50%.

This will impact a LOT more investigations than Graphene, and I imagine Apple will be back in court fighting cops who want to remove privacy and security features. Hopefully this stuff stands up to the autocrats coming into power in the states.

[–] BorgDrone@lemmy.one 27 points 1 week ago

don't let apple tell you they invented it.

Why always the knee-jerk anti-apple reaction even if they do something good?

FYI: Apple isn’t telling anyone they invented this. In fact, they didn’t even tell anyone about this feature and declined to comment after it was discovered and people started asking questions.

There is no shortage of reasons to dislike Apple. This isn’t one of them.

There is a scene in Mr Robot where Darlene is able to do a full wipe on her phone without even looking at the screen.

I wish I was that good.

I want a way that I can trigger this from the main lock screen without unlocking the phone.

Like a specific pin you have to enter twice to trigger the full wipe.

[–] hydration9806@lemmy.ml 33 points 1 week ago (2 children)

GrapheneOS has this. I believe it's called a Duress PIN.

I feel that a lot of the hate for Apple is not fully warranted. Contrary to Google or Facebook, their business model is not built on collecting your personal data. They are extremely overpriced, but deliver good quality - I am using my first iPhone for more than 4 years now, I never had and Android last nearly that long.

As a member of the intelligence community, I can almost guarantee that this is directed at the increased use of Cellebrite UFED hardware, specifically putting the device back into BFU mode, which removes cryptography-related memory allocations. This is also why you're asked for your password instead of face or fingerprint upon reboot.

[–] phoneymouse@lemmy.world 26 points 1 week ago (7 children)

I don’t know how Cellebrite is a legally operating company. Their entire business model is a violation of the computer fraud and abuse act.

[–] ilega_dh@feddit.nl 33 points 1 week ago

No that’s only for when poor people do it

Which is great, because you can't warrant a password.

The way this article is framed sounds like bullshit to me. 18.1 was released less than 2 weeks ago. Any phone running this version of iOS would have had to already been in custody and somehow upgraded to this version, or otherwise brought into custody very recently—too recently for this to have already posed such a problem that law enforcement is “freaking out” and reporting it to the media.

[–] viking@infosec.pub 25 points 1 week ago (3 children)

Don't they auto update the OS when connected to a charger? But even then, that would have triggered a reboot already.

Wouldn't that disrupt the usage of a phone as a server?

Meanwhile security-oriented Android forks: "You didn't do that?"

[–] shortwavesurfer@lemmy.zip 24 points 1 week ago* (last edited 1 week ago) (11 children)

Actually, Graphene and Calyx have this feature. I believe graphene may have it on by default at 18 hours, but I do not know about Calyx.

I think this used to be possible with tasker, ironically though probably not anymore before of all Google's restrictions on Android. (maybe if you have root)
