Apple has successfully blocked the “GrayKey” hack that allowed law enforcement and governments around the world unfettered access to passcodes on Apple devices running iOS. Devices running iOS 12 and above can only have metadata such as file structure and unencrypted files accessed by Grayshift technology. GrayKey used brute force techniques and circumvented Apple’s block on repeat guesses.



Police officer Captain John Sherwin of the Rochester Police Department in Minnesota said of the claim iOS 12 was preventing GrayKey from unlocking iPhones: “That’s a fairly accurate assessment as to what we have experienced. “Give it time and I am sure a ‘workaround’ will be developed … and then the cycle will repeat. Someone is always building a better mousetrap, whether it’s Apple or someone trying to defeat device security.”
