Apple hasn't fully disclosed how the vulnerability would have worked.
The fault is reminiscent of a serious Group FaceTime bug discovered early this year which could allow callers to hear the recipient without the call being accepted.
Apple has disabled the Walkie-Talkie app for Apple Watch after a vulnerability that potentially allows for eavesdropping on iPhone conversations emerged.
The Walkie Talkie app allows two people with Apple watches to add each other, then enter a voice chat via a touch-and-hold system.
The Walkie-Talkie app - which has now been switched off - could remotely listen in to an iPhone through its microphone, Apple has warned.
The bug was reported to Apple through its security portal, TechCrunch noted, but there's apparently no evidence that it was exploited before the company was alerted. When contacted by Business Insider for further details, Apple referred us to the statement given to TechCrunch.
"We apologise again for this issue and the inconvenience".
We were just made aware of a vulnerability related to the Walkie-Talkie app on the Apple Watch and have disabled the function as we quickly fix the issue. While we don't know the "specific conditions and sequences of events" a potential malicious agent could have employed to exploit the vulnerability against actual users, its nature sounds pretty scary.
"We apologise to our customers for the inconvenience and will restore the functionality as soon as possible". While somewhat gimmicky, we can absolutely understand why certain users would find Walkie-Talkie useful in certain scenarios when writing a text or making a call on their iPhone is simply not as convenient.
The issue - which was a problem with the Zoom video chat app rather than with Apple's own software - let crooks turn Mac webcams on remotely.
