Apple Refutes Hacker's Claim He Could Break iPhone Passcode Limit (cnet.com)

A security researcher claimed he had figured out a way to bypass the passcode lock limit on an iPhone or iPad, ZDNet reported. But it turned out the passcodes he tested weren't always counted. From a report: "The recent report about a passcode bypass on iPhone was in error, and a result of incorrect testing," Apple said Saturday in an emailed statement. Since the 2014 release of iOS 8, all iPhones and iPads have come with device encryption protected by a four- or six-digit passcode. If the wrong passcode is entered too many times, the device gets wiped, explained ZDNet's Zack Whittaker. But Hacker House co-founder Matthew Hickey figured out a way "to bypass the 10-time limit and enter as many codes as he wants -- even on iOS 11.3," Whittaker wrote.

      A "normal" hacker might fail because he only use a single list, while some government agency might have a prepared list of entries that are multiplied and maybe quasi randomized in some prepared way, so that a device dropping entries doesn't matter if the odds are that the device will successfully run through all passwords entries, despite dropping the occasional entry.

      Am I misunderstanding how the iPhone dropped some of the entries on "testing"?

      You mean it was an unclear summary. The story itself lays it out: the hacker said there is a way to send a stream of passcode attempts via cable to the iPhone which would override the 10 attempt limit. He later had to admit is that the method he used did not always send the attempt correctly to the phone and it was ignored thus not hitting the limit. He thought he sent 20 attempts when reality it was 5 or 6.

      Not quite - he send all attempts, but after the 5th the iPhone doesn't accept any entries for 1 minute but (at least when using an external keyboard or pretending to) the GUI still looks like you enter numbers.

  13. Option in settings... by The+New+Guy+2.0 · · Score: 4, Informative

    I can type ten bad passwords into my iPhone and not have it wiped. It's an option in settings that when turned off causes the phone to freeze and not accept a new attempt for a progressively longer time.

    So there you have it, not all iPhones wipe after ten bad attempts.

    1. Re:Option in settings... by Anonymous Coward · · Score: 0

      The "wipe the phone" part was very likely a simplification of speech, and a reasonable one as that is the default setting.

      It would be more accurate but longer to explain to say "trigger the failed unlock handler" followed by the different options that could end up triggering.

      But overall the researchers method was still flawed and doesn't actually bypass that feature no matter what the end result is configured to do.

      He found a way to send many PINs in succession over one attempt, but in reality it seems this doesn't actually work despite the phone claiming it did.
      (To be fair, my email spam filters work similar, they do not respond at all to the attacker making it appear the email was delivered, despite the fact it was not. This is to throw off the bad guys, since if the spam was delivered there would be no need to even try working around the filters)

      It seems in this case he was sending 30 PINs over a single unlock request, and the phone implied/lied that it tried all of them when it didn't.
      So he thought that because 30 is greater than 10, he was bypassing the limitations.
      Or the fact he could send 270 PINs with no failed-pin-trigger, when the 271's actually did trigger it.

      Apple says the phone only attempts and counts the first of the 30 in that single request.
      If that's true it does add up.
      30 pins per batch times 9 batches would imply 270 PIN checks, but as it only attempted the first one in the batch it was really only 9 PINs tried, which is certainly under the limit of 10.
      The very next try, batched or not, would be 9+1=10, not 270+1 as the researcher thought.

      Also if what Apple says is true, since it only tried 9 out of the 270 pins, there are 261 pins ignored. Thus if the correct pin is in there somewhere but in the 261 group, that pin wouldn't unlock the device and be shown as valid.

      So hopefully what Apple says is correct. The researcher apparently responded, checked, and found it to be true, so that's at least promising.
