Joseph Cox, and Lorenzo Franceschi-Bicchierai, reporting for Motherboard: Apple confirmed to The New York Times Wednesday it was going to introduce a new security feature, first reported by Motherboard. USB Restricted Mode, as the new feature is called, essentially turns the iPhone’s lightning cable port into a charge-only interface if someone hasn’t unlocked the device with its passcode within the last hour, meaning phone forensic tools shouldn’t be able to unlock phones. Naturally, this feature has sent waves throughout the mobile phone forensics and law enforcement communities, as accessing iPhones may now be substantially harder, with investigators having to rush a seized phone to an unlocking device as quickly as possible.
That includes GrayKey, a relatively new and increasingly popular iPhone cracking tool. But forensics experts suggest that Grayshift, the company behind the tech, is not giving up yet. “Grayshift has gone to great lengths to future proof their technology and stated that they have already defeated this security feature in the beta build. Additionally, the GrayKey has built in future capabilities that will begin to be leveraged as time goes on,’ a June email from a forensic expert who planned to meet with Grayshift, and seen by Motherboard, reads, although it is unclear from the email itself how much of this may be marketing bluff. “They seem very confident in their staying power for the future right now,” the email adds. A second person, responding to the first email, said that Grayshift addressed USB Restricted Mode in a webinar several weeks ago.
