Apple added a feature to iOS 17.3 that appears to address an iPhone security vulnerability that lets thieves steal iCloud accounts using only a user’s iPhone PIN.
Apple has fixed a years-old vulnerability in its iPhone and iPad software that undermined a privacy feature since it first debuted. Back in 2020, Apple announced a new feature in iOS 14 that would prevent nearby wireless routers and access points from gathering an Apple device's unique MAC address. Tracking MAC addresses can have legitimate uses, like allowing administrators to identify every device connected to their networks, such as unauthorized devices.
