Face ID: iOS 15 removes weaknesses in Apple’s face recognition

Apple has fixed a security gap in the Face ID biometric authentication system with iOS and iPadOS 15: An attacker with a 3D model of the owner’s face may be able to log in with Face ID, Apple announced after the operating system updates were released . The problem has been eliminated by improving the anti-spoofing technology, which is intended to detect and prevent such fraud attempts.

Further details on the Face ID gap have not yet been disclosed. Accordingly, it remains unclear how complex it is to create such a mask and whether it could also be used to outsmart Apple’s “attention check”, which checks whether the device is also looked at by a person with open eyes when logging on. Found the weak point according to Apple the Chinese security researcher Wish Wu of the Ant-financial Light-Year Security Lab.

Wu has apparently been involved in outsmarting biometric authentication systems like Face ID for a long time. In 2019, the hacker had announced a lecture at the Black Hat conference that was supposed to show how Face ID can be outwitted – but suddenly withdrew it and thus sparked speculation. Allegedly he only used a black and white photo and tape for his hack, but it may not work reliably either. In 2017, Vietnamese security researchers caused a sensation with a twin mask that allegedly could be used to unlock Face ID iPhones – but questions remained unanswered.

According to Apple’s previous information, iOS and iPadOS 15 eliminate a total of 22 vulnerabilities, including serious gaps in the kernel and WebKit that allow malicious code to be executed. The Federal Office for Information Security (BSI) has the errors in the highest risk level 5 and recommends an update as soon as possible. Apple has already eliminated many of the weak points this time with iOS 14.8, as has only just become known – users have the option to stay on iOS 14 without having to forego security updates. According to Apple, the Face ID gap was only fixed in iOS 15.
