A bug that has been recently discovered in Apple’s FaceTime software allows people to access another person’s microphone and camera during an incoming call, all without the other person’s consent or knowledge.

The glitch is reportedly running on all iPhone or iPad currently using iOS 12.1 or later (or PCs running macOS Mojave) which contains the Group FaceTime feature.

When you dial a contact’s number in the FaceTime app, swipe up from the bottom and tap “Add Person.” Then add your own phone number. The software now thinks you’re on a group call, and you’ll be able to hear audio from the other person’s microphone even if they don’t pick up.

It has also been reported that the bug can allow someone access to your front-facing camera as well. If a user presses a volume button during the incoming call, the caller can see live footage from their phone.
