San Francisco, January 29: Apple has acknowledged a flaw in its FaceTime software that allowed for brief eavesdropping -- even if the recipient did not pick up. In some cases the target iPhone would send video, probably without the receiver's knowledge, the BBC reported.

The flaw, first revealed by the 9to5Mac blog, appears to occur when both users are running version 12.1 of Apple's mobile operating system, or newer. Apple said it has developed a fix and the update would be rolled out this week. Apple Introduces Downtime Customization Feature To iOS 12.2 Beta Update - Report.

The technique involves using the software's group chat function, apparently confusing the software into activating the target's microphone, even if the call had not been accepted. The eavesdropping ends when the call is cut after too many rings.
