Now that FaceTime is disabled, callers will be unable to utilize this bug to listen and watch you without your permission through FaceTime. 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.
If the recipient hits the phone's power button, thinking they've declined the call, another curious bug kicks in. It appears that the bug affects any device running iOS 12.1 or later, and can be exploited by starting a video call, then adding your own number as a third participant before the call is picked up.
Apple Inc. customers discovered a software bug on Monday that lets people listen in on other users by way of the company's FaceTime video chat service.
As far as security flaws go, this one is particularly serious, especially given the emphasis has Apple placed on privacy recently when it comes to its devices and operating systems. By doing this, the call becomes a group call and the recipient's audio becomes available even if they haven't answered. When testing it against an Apple Watch, though, we were not able to get the audio portion of the bug to work.
In a statement to ABC News, a spokesperson for Apple said, "We're aware of this issue and we have identified a fix that will be released in a software update later this week". And that could be a very, very, very disastrous bug (via 9to5Mac). In the meantime, you'll probably want to disable FaceTime and maybe sleep with your iPhone outside the bedroom for a bit.
On an iPhone or iPad, head to Settings FaceTime and toggle FaceTime off.
