In a world where you're identity is always known and your Alexa can listen to you and people have access to your phone number, it's uneasy feeling hearing this story if you're an iPhone person.

There is a bug in FaceTime that lets you hear through someone else's iPhone without their consent. Devices that run iOS 12.1. Apparently, the bug will be fixed after the next system update, so to stop the problem you must disable FaceTime as of now.

How does it work?

It is activated when you call someone via FaceTime, swipe up to add another person to the call, and add your own phone number. The person who initiated the call is then able to hear the live audio on the other person's phone, even though the recipient has not accepted the call. And their screen gives no indication that their conversation is being transmitted. In some cases, the bug can also show live video of the other person if they press a volume button to dismiss the call", according to CNN.
