A bug in FaceTime has been discovered, allowing callers to listen to the audio of the person being called before they pick up. The bug was found by a 14-year-old high school student from Tucson, Arizona who was chatting with friends about Fortnite when he stumbled upon it while calling his friends. Apple has shut down the back-end services that provide the vulnerable functions and expects to fix the issue by the end of this week. As a precaution, users are advised to disable FaceTime on their devices until the issue is fully fixed. The bug highlights the importance of security testing and education, as well as the need for proactive measures to protect against vulnerabilities. Apple's approach to security has been praised, with sympathy extended to the company's security team who have likely had limited rest since the news broke. Users are advised to disable FaceTime on their devices until a fix is confirmed, and to take steps to protect themselves and loved ones from potential exploitation of the vulnerability.
