All was going well during the National Privacy Day in the U.S., with Apple’s Tim Cook commemorating the event by emphasizing on the importance of data privacy until one of the offerings of the Cupertino giant was attacked by a bug. Apparently, a kink has been discovered in FaceTime and it is a little unsettling as it can enable the caller on the other side to eavesdrop on you, by granting them access to the recipient’s microphone and camera before they even pick up the call from their end.

The bug in the FaceTime software will allow a caller to listen in on the audio from the recipient’s end even if the call hasn’t been received. The glitch apparently appears when both the caller and the receiver are running iOS 12.1 or newer on their iPhones. In fact, it even affects Mac users if they are being called by an iPhone user. The only assuring fact is that since the phone rings normally, the caller can’t be entirely covert about it.
