Earlier this month, I woke up to a disastrous security bug in Apple’s FaceTime that could let anyone easily eavesdrop on iOS and macOS devices. In case you haven’t heard about it yet, FaceTime, the audio and video conferencing app that comes preinstalled on all iPhones, iPads, and Mac computers, had a major security flaw that could let a caller hear the audio from the device they were calling before the person on the other end accepted or rejected the call.

The bug could easily be reproduced and exploited. All you need to do is initiate a call with FaceTime and use its group feature to add your own number while the recipient’s device is still ringing, and you’ll be able to hear what they’re saying. In fact, the flaw was reportedly discovered by a 14-year-old a week before it was reported by 9to5mac.com and acknowledged by Apple.
