A security researcher has figured out a way to bypass the passcode lock limit on an iPhone or iPad, ZDNet reports.
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, explains ZDNet’s Zack Whittaker.
Hickey “explained that when an iPhone or iPad is plugged in and a would-be-hacker sends keyboard inputs, it triggers an interrupt request, which takes priority over anything else on the device,” Whittaker wrote.
“Instead of sending passcodes one at a time and waiting, send them all in one go,” Hickey told ZDNet. “If you send your brute-force attack in one long string of inputs, it’ll process all of them, and bypass the erase data feature.”
The method, Whittaker adds, will “be affected by Apple’s upcoming USB Restricted Mode, which locks the Lightning port on an iOS device if it hasn’t been unlocked within the last hour.”
