    Hi all :) I've added some answers to all your questions at the end of my blog post. naehrdine.blogspot.com/2024/11/reverse-engineering-ios-18-inactivity.html

    The fact that the reboot is in verbose mode is interesting. Apple usually *really* doesn't allow things like that on production releases of software.

      That’s because it’s a research device. That iPhone is likely Apple’s property that they’re allowing devs to use for testing purposes.
      Inactivity reboot is going to be a normal reboot on end-users’ iPhones

      Nah, I think the blur is an overlay. Look how the notch is also blurred.

      @Platapai Месяц назад +102

      It's an Apple Security Research Device. Apple loans you a phone (which isn't for personal use)
      It's used to find, test, validate, verify, and confirm a vulnerability

    • @bendabuilder6637

      It's a security research device, part of one of Apple's programs. It has it enabled by default

    is this for like re-encryption?

    • @tdrg_
      @tdrg_ Месяц назад +19

      Yeah, in BFU state pretty much all user data is encrypted

    • @busterscrugs
      @busterscrugs Месяц назад +24

      Yup, prevents law enforcement from accessing data from your locked phone.

    • @Tougebeat
      @Tougebeat 27 дней назад +1

      Is this the same encryption as with a factory reset?

    • @michaelthornes
      @michaelthornes 23 дня назад +6

      this resets the phone from an AFU (after first unlock) state to BFU (before first unlock) state, part of this meaning encryption keys are purged from memory and you must use your pin/password instead of just biometrics to unlock the first time. this makes it more difficult for law enforcement or other phone thieves in general to access the data on the phone, because they need to get the encryption keys, there are no potential bypasses, memory-related or otherwise

      This is an SRD, a modified iPhone for security research sent by Apple to experts

    • @busterscrugs
      @busterscrugs Месяц назад +4

      No, by rebooting the device, it's now in "before first unlock" mode, where all user data is encrypted.

  • @NilanjanMustafi
    @NilanjanMustafi 27 дней назад +4

    Once every 7-10 days when I try to unlock my iPhone 13 on iOS 17.4.1, iOS asks me to first enter my password. Is that same as what's shown in the video i.e., BFU or is that AFU?
    Also, when I press the power + volume buttons together for a couple of seconds and don't shut down my iPhone, it asks for my password. Is this BFU or AFU?

    • @jiskac
      @jiskac  25 дней назад +4

      Both scenarios you describe are AFU. The second one restricts some interfaces but disk stays decrypted.
      You can easily try that out when calling your iPhone: In BFU, no contact info is shown. In AFU, contact info from your address book is shown.

    Idk, every unstable system requires a reboot at least once a week. Otherwise, system performance will feel slower than usual.

    Oh now I get it, that’s why sometimes when I’m trying to swipe up my phone it needs a passcode first because it reboots 😅😅

    • @jiskac
      @jiskac  28 дней назад +6

      Not necessarily. Apple also put some other mitigations in there that require you to enter the passcode under certain conditions. In some of these cases, the iPhone didn't reboot and is still in After First Unlock state.
