Security researchers say they've found a way to get around an antihacking feature in Apple's iOS 12 beta and in the newly released iOS 11.4.1, which came out Monday.

USB Restricted Mode is designed to shut off access to data on an iPhone or iPad when new USB accessories are plugged into the Lightning port, as long as it's been more than an hour since you last unlocked your iPhone. The feature prevents people from using gadgets such as the GrayKey tool from accessing the phone's information.
