A hacker has discovered a way to bypass the passcode on iPhones running on iOS 12.
Jose Rodriguez, a security researcher who regularly posts YouTube videos about smartphone flaws, discovered the issue.
In a video demonstrating the flaw, he showed how it was possible to access the photos and contacts on an Apple smartphone without needing to put the passcode in.
His method starts by asking Siri to enable Voiceover.
Using a second phone, he then calls the victim’s handset.
While the phone is ringing, he opens the messages menu, before sending a text from the second smartphone.
A blank white screen appears, but using Siri voiceover, he is then able to navigate the underlying menu, and access the victim’s photos and contacts.
How to protect your smartphone
There are several ways to protect your iPhone.
Firstly, the technique doesn’t appear to work for iPhones with Face ID enabled – however, this is only available on the iPhone X or newer models.
