It seemed that iOS 12 was going to escape without any serious security flaw, but it has not resisted and a very important problem related to calls using FaceTime has been found. The failure is that when someone makes a call using this system, without your accepting it, the person making it can hear you. In addition, if they make a call and press the power button to silence it, you will also send video.
It is undoubtedly a major security flaw that Apple must correct immediately, and has made it known to the media, announcing a solution this week. What's more, as a preventative measure, you have disabled group FaceTime calls until the solution is up and running. We give you all the details below.
Only with group calls
It is important to note that this bug can only be reproduced by group calls. In order to listen to the audio of the person you are calling without their consent, it is necessary that you call them through FaceTime, and that without taking the call, add another person to it (even if it is yourself). It will be at that moment when you will begin to listen to the audio of the person you were calling first without accepting it.
Worse yet, if that other person you call press the power button to mute the ringtone, you can even watch it on video, as if he had accepted the video conference. From that moment it will listen to you too, but it will not know that it is sending its video and sound to you. This bug can not only be replicated on iOS but also occurs on macOS. Another important detail is that with the Do Not Disturb option activated, the failure cannot be reproduced either.
Workaround: disable group calls
The ruling has been massively disseminated by the networks and the impact it is having is enormous, so much so that Apple has already admitted that it is working on fixing it and that this week it will release an update that will fix it. Until then, you have disabled group calls, this will prevent the failure from being reproduced until the solution is available through a software update.
