Grayshift says it has defeated Apple's USB Restricted Mode allowing it to crack open any iPhone

Yesterday, we told you about a change Apple has said it will make in iOS 12 to the Lightning port's settings in order to reduce the ability of law enforcement and hackers to crack open a locked iPhone. Apple is calling this the USB Restricted Mode. Most cracking machines use the Lightning port to get around limits Apple has placed on the number of attempts cops and hackers have to figure out an iPhone user's password. This "brute force" process tries every possible combination of numbers and letters to open an iPhone. The change in iOS 12 stops the Lightning port from being used to communicate with another device if an iPhone has not been unlocked within the previous hour.

But before Apple could say "checkmate," Grayshift, the company that manufacturers the GrayKey cracking machine, says that it has already defeated the upcoming USB Restricted Mode. If true, that puts the ball squarely in Apple's court as pressure will mount inside Cupertino to respond with another way to prevent these machines from opening an iPhone so that law enforcement and hackers can access personal data inside it.

According to Motherboard, an email it has seen was sent this month by a forensics expert who was supposed to meet with Grayshift. The email says that Grayshift claims that it has defeated the Restricted USB Mode feature in a beta build of iOS 12. Additionally, the company made it clear that the GrayKey has many capabilities that it will be able to use in the future to stay one step ahead of Apple.


While Grayshift appears confident in its ability to defeat USB Restricted Mode, rival Cellebrite, not so much. VP of research at the Israeli firm, Shahar Tal, sent out a tweet today that read, "tmw (That moment when) 10 of the last 12 threads in my inbox have 'USB Restricted Mode' in the subject line, and you realize it's just the beginning."
