Cops Told 'Don't Look' at New iPhones To Avoid Face ID Lock-Out (vice.com)

As Apple continues to update its iPhones with new security features, law enforcement and other investigators are constantly playing catch-up, trying to find the best way to circumvent the protections or to grab evidence. From a report: Last month, Forbes reported the first known instance of a search warrant being used to unlock a suspect's iPhone X with their own face, leveraging the iPhone X's Face ID feature. But Face ID can of course also work against law enforcement -- too many failed attempts with the 'wrong' face can force the iPhone to request a potentially harder to obtain passcode instead. Taking advantage of legal differences in how passcodes are protected, US law enforcement have forced people to unlock their devices with not just their face but their fingerprints too. But still, in a set of presentation slides obtained by Motherboard this week, one company specialising in mobile forensics is telling investigators not to even look at phones with Face ID, because they might accidentally trigger this mechanism.

"iPhone X: don't look at the screen, or else... The same thing will occur as happened on Apple's event," the slide, from forensics company Elcomsoft, reads. Motherboard obtained the presentation from a non-Elcomsoft source, and the company subsequently confirmed its veracity. The slide is referring to Apple's 2017 presentation of Face ID, in which Craig Federighi, Apple's senior vice president of software engineering, tried, and failed, to unlock an iPhone X with his own face. The phone then asked for a passcode instead. "This is quite simple. Passcode is required after five unsuccessful attempts to match a face," Vladimir Katalov, CEO of Elcomsoft, told Motherboard in an online chat, pointing to Apple's own documentation on Face ID. "So by looking into suspect's phone, [the] investigator immediately lose one of [the] attempts."

    If you just stick to a decent password, not only will it help those forgetful law enforcement types ( because it won't matter if they look at your phone or not ) but you also cannot be forced to give up a password ( in the US at least . . . . for now ) so it's a win-win for everybody :D

Key it in even once and the phone encrypts the entire phone ( just to be sure ) to some random key ( plausible deniability. . . . you truly won't know the passcode to unlock it at that point ) or just runs an embedded version of Bleach-Bit ( or similar ) that kills any hope of pulling any data from the device at all.

      It was tried. Before we used fingerprints, the vast majority of phones did not even have a simple 4-digit PIN on them. Why? Because it was discovered that entering a 4-digit PIN was too much effort, when done about 1,000 times a day. Or more correctly, if you're only going to glance at your phone for under 30 seconds, spending 5 to unlock it was a huge deterrent.

      And yes, that's the usage pattern of a lot of phones - the phone is unlocked to check status and everything which takes a few seconds, but happens hundreds of times a day. So even if they had a PIN set up, it quickly got disabled just out of annoyance.

      Biometrics boosted the number of locked phones since you're not entering you're password thousands of times a day.

      Of course, because of the police thing a number of phones have a "disable biometric" mode. For iOS, press the side button and either volume up or down button for a second and it'll enter "SOS" mode. This requires the password to be entered in order to unlock the phone.
