> Malwarebytes’ post says GrayKey can unlock an iPhone in around two hours, or three days or longer for 6 digit passcodes.

So couldn't you avoid this by, say, having a longer PIN? Maybe even a password?

Yeah I’m curious about how this would work with a longer pin. I have one that’s over 6 and you need to press ok after punching in the pin; making it much harder to crack I’d imagine.

And couldn't Apple defend against this by using an exponentially increasing wait period between guesses? Probably after some number of guesses with no delay, say 10 guesses.

They already do that--but this box somehow bypasses that security measure.
