Apple Just Killed The 'GrayKey' iPhone Passcode Hack
"Nobody knows how?" They have a pretty plausible explanation in the back half of this very article:<p>> With iOS 12, Apple implemented a highly-anticipated change called “USB Restricted Mode.” This shuts off lightning port access on the iPhone if it hasn’t been unlocked by a user in the last hour. This was widely believed to be Apple’s solution to foil companies like GrayShift and Cellebrite but we don’t know for certain if that did the trick. Apple did not return our request for comment.<p>That would definitely do it. If Lightning goes down they cannot differentially backup/restore while attempting to guess the user's passcode.
