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.
On one hand, Fuck Da Police
On the other hand, Fuck Apple
Do two fucks make a right?
GrapheneOS been had this feature, don’t let apple tell you they invented it.
Great software features should be available to all hardware, regardless of OS.
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.
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.
All six GrapheneOS users should be proud that the developers of their phone software are genius inventors!
Judging by the downvote count, I was off by 2x. My apologies to the community!
(For the record, I have nothing against GrapheneOS, but also no use for it)
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.
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!
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.
Although lockdown mode is a good step and helps defend against biometric warrents, it does not wipe the encryption keys from RAM. This can only be achieved by using a secondary (non-default) user profile on GrapheneOS, and triggering the End session feature. This fully removes the cryptographic secrets from memory, and requires the PIN or password to unlock, which is enforced through the StrongBox and Weaver API of the Titan M2 secure element in Pixel devices.
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.
graphene is ONLY for select Google pixel phones though. I wish this was made much clearer by the team and advocates.
its a real shame because pixels, although big in the USA are typically a minority of most android ecosystems elsewhere, and bootloader hijinks keep some perfectly capable phones from being easy to switch over to, even if they were supported.
Even on samsungs, which are much better for flashing than they used to be - my options on a year old flagship for a decent ROM are pathetic compared to the old days.
so I would really love to use graphene, and go back to an open source ROM without crap on it, but pixels are such a bottom tier phone for their price in a lot of places, as much as I really really want the project go gain traction for their transparency and objectives.
I’m the only guy in my (small) friend group who still used pattern code instead of fingerprint so I take that to mean my phone is by default more difficult to break into than most. Giving my fingerprint to a giantic tech firm has always seemed like a bad idea so I never did. Though the fingerprint reader acts as a power button too so who knows if they’ve scanned it anyway.
Well, when you confiscate a piece of paper, even without a warrant to read it you can do that physically when it’s in your possession, and it’s part of the evidence or something, so everyone else can too, so why even fight for that detail.
They just pretended it’s fine with mobile computers.
I thought that “fruit of a poisonous tree” is a real principle, not just for books about Perry Mason. /s
So - yes. It’s just really hard to trust Apple.
To confiscate anything, unless it’s lying openly, you need a warrant.
If a cop sees an unlocked phone with evidence of a crime on it, that doesn’t need a warrant. If it’s locked and they only have the suspicion of evidence, they need a warrant. Same as with entering a building or drilling a safe.
Is analogy with people in (very quiet) places who don’t lock doors to their homes correct? Then it’s as if the door is not locked, a cop doesn’t have to ask permission (or warrant)?
That argument sounds great until you consider that a piece of paper won’t contain almost the entirety of your personal information, web traffic, location history, communications. You may say you could find most of that pre computer era in someone’s house, but guess what you would need to get inside and find those pieces of paper…
They usually do have a warrant or it was seized lawfully.
This is about keeping them out even when it’s lawful.
Lawyer. Not true.
Example: An officer pulls someone over and suspects them of something arrestable. Then says “Do you want me to get your personal belongings from your car?”
Any person agreeing to this allows them to hold your phone as evidence indefinitely in the US now.
That’s all lawful.
They can search you and the area when arrested. They can search the car if they have probable cause that evidence will be in the vehicle
I said have a warrant or seized lawfully, not nust have a warrant.
Edit: I didn’t even write what I said I said correctly. Corrected it lol.
The police can engage in rubber-hose cryptanalysis. In many countries, it’s legal to keep a suspect in prison indefinitely until they comply with a warrant requiring them to divulge encryption keys. And that’s not to mention the countries where they’ll do more than keep you in a decently-clean cell with three meals a day to, ahem, encourage you to divulge the password.
That’s what you need distress codes for.
Destruction of evidence is a much different crime.
I would suspect it’d no longer be legal to hold them indefinitely and instead at best get the max prison sentence for that crime instead.
A us law website says that’s no more than 20y as the absolute max, and getting max would probably be hard if they don’t have anything else on you.
You’d have to weigh that against what’s on the device.
Also, even better if the distress code nukes the bad content, and then has a real 2nd profile that looks real, which makes it even harder to prove you used a distress code.
IT support everywhere sigh in satisfaction
