  • "The duress PIN doesn’t give you a second chance and will trigger anywhere you enter it: on the lockscreen, while enabling Developer options, or even while unlocking an app that requests authentication. And unlike a regular factory reset, a duress PIN will erase all encryption keys and your phone’s eSIM partition as well. This makes it impossible for an attacker to access my data just by having physical possession of your device and knowledge of the PIN.

    I think the real strength of GrapheneOS’ duress PIN lies in its subtlety. There are no confirmation prompts, no announcements, and no obvious signs that the wipe was intentional on your part. Of course, GrapheneOS is no longer a fringe operating system these days — it has even attracted the ire of law enforcement in some jurisdictions. In other words, a professional attacker might be aware of the existence of a duress PIN. But if you can enter it quickly enough, it achieves its intended effect: no data can be lifted from your phone."

    Pretty plainly stated:

    Main purpose - delete all data

    A nice bonus - the process is semi hidden, no way to confirm mistakes or not

    Purpose is NOT - Fool any attacker to think they have your phone even though it’s wiped

    So it’s most definitely doing it’s job. You think that job is not enough, fair, but it’s living up to it’s own stated purposes.

  • They asked to unlock his phone, he entered the wipe instead personal pin, and the wipe starts, with no possible reversal.

    I mean yeah they discover it when he hands them the phone and it shows something other than an unlocked screen… But he is still in detention? Making a fake homescreen will fool them for like 30 secs tops until they open literally any app and sees it’s either completely empty or that it doesn’t work.

    What would that solve? It just drags out the procedure

  • Very interesting, but after reading, it specifically states that it’s the multi scaling that has a function on the battlefield, which can be implemented through all shapes basically.

    The ‘digital’ (square) patterning is most certainly either cost saving measures, fashion, or both.

    “The pixellated style, however, simplifies design and eases printing on fabric, compared to traditional patterns. While digital patterns are becoming widespread, critics maintain that the pixellated look is a question of fashion rather than function.[7]

    Now I’m aware you just stated that ‘it had a practical purpose’ but your tone and framing suggests to me something other than ‘its easier and cheaper to manufacture’.
