Security flaw allows iPhone users to drop-in on contacts via FaceTime

Share

It appears that Apple inadvertently introduced a FaceTime bug with the release of iOS 12.1 late a year ago. This particular bug allows a caller to hear audio and see the camera feed from their recipients even though they didn't pick up the call.

As a result of the bug, it's actually possible to listen to an ongoing FaceTime conversation without the person on the other end knowing you can hear them. The release of Apple's Group FaceTime calling feature was delayed a number of months due to software bugs. In some cases, the bug can also show live video of the other person if they press a volume button to dismiss the call.

After a video of the bug being exploited went viral on social media, Apple-focused news site 9to5Mac broke down the steps necessary to replicate it. When testing it against an Apple Watch, though, we were not able to get the audio portion of the bug to work.

To use this bug, a caller would FaceTime another person who has an iOS device and before the recipient answers, add themselves as an additional contact to Group FaceTime.

When 9to5Mac first reported on the bug, they were only able to get the microphone snooping working.

In order to deactivate FaceTime on your iOS device, navigate to "Settings, ' then tap on 'FaceTime" and select 'Off'.

"We're aware of this issue and we have identified a fix that will be released in a software update later this week", an Apple spokesperson said in a statement. In the meantime, you'll probably want to disable FaceTime and maybe sleep with your iPhone outside the bedroom for a bit.
