Apple has recently pushed out a security update that will address FaceTime on both iOS and OS X platforms. Just in case you’re hearing about this for the first time, there was a vulnerability that allowed someone in a privileged network position to force audio transmission from a FaceTime call.
The flaw was originally reported to Apple by researcher Martin Vigo, and given that we haven’t really heard anything about it so far, there is a good chance that no one has had the opportunity to exploit the vulnerability yet, so thankfully it has been addressed before something serious happened.
Unsurprisingly Apple does not dive into the details about the vulnerability, presumably they don’t want hackers to be “inspired” by it, but either way it should be fixed so do keep an eye out for those security updates if you’d like to ensure that your FaceTime calls remain private.
