Apple FaceTime Bug: Teenager Spotted Vulnerability 9 Days Ago

Was vulnerability reported 9 days ago and ignored?

By CBR Staff Writer

A soon-to-be famous teenager discovered a major Apple FaceTime bug in its group chat feature nine days ago, it appears, with Twitter user MGT7500 tagging the official Apple Support account in a January 20 tweet that claims their 14-year-old son discovered the “major security flaw”, but drawing no response.

The bug allows users to hear audio from the person they’re calling – even before they have answered the phone. Knowledge of how to use it spread virally after being picked up by users and then reported on It is believed to have affected any pair of iOS devices running iOS 12.1 or later.

The apparent early identification of the bug sparked a flurry of interest on social media as journalists awaited the story, and also triggered a fresh debate about the utility or otherwise of bug bounty programmes.

With Apple having disabled group FaceTime chat functions until the issue is patched, some users had other, older fashioned suggestions to boost smartphone security amid seemingly endless vulnerabilities and user data exploitation issues: introduce hard switches for microphone, camera and GPS.

It seems unlikely to happen anytime soon, but the enterprising manufacturer that gives users back real control might just make a fine profit.
