FaceTime Bug Enables Exploit

On January 28th, a bug was discovered in the Apple FaceTime feature that allows a user to eavesdrop on FaceTime users via audio and video for a brief period. The bug resides in the Group FaceTime feature and is trivial to exploit. Listening in to audio does not require interaction by the recipient while enabling video requires minimal interaction.

Apple has temporarily disabled Group FaceTime on the server side, and is planning to address the flaw in a software update for devices this week although no official date is available at this time [1]. Due to the risk of information loss and the trivial nature of exploitation, disabling FaceTime should be considered until the device software update has been released by Apple.

Since first publications Apple has released a security update to mitigate this issue.

What we’re doing about it

What you should do about it

Additional information

Exploiting the bug requires three simple steps:

  1. Call the intended target on FaceTime
  2. While the call is dialing, press the Add Person option
  3. Invite yourself to the call through the Add Person option

These three steps initiate the call without waiting for the target to accept; allowing for audio eavesdropping. If the recipient presses the Power button or the Volume Down button, video is also sent to the caller [2].
