Apple was experiencing a major embarrassment earlier. When calling a built-in FaceTime call, even if the other party did not pick up, they could directly hear the other party’s voice through a series of operations, which is simply using the iPhone as a bug.
Since at least iOS 12.1, a simple manipulation indeed offers the user the opportunity to hear what is happening to his correspondent without even stalling. This has caused privacy issues for many iOS users, and several outlets have already exposed it.
This bug, which has been able to reproduce several times, has not been corrected with the first beta of iOS 12.2. It is possible, in view of its media coverage, that Apple delivers a quick update quickly to close the hole, unless the vulnerability can be corrected server side.
In the meantime, there is no real cure except to switch to Do Not Disturb mode, or disable FaceTime or hold your tongue before taking the call.
Apple swiftly responded by telling US sites that they are responsive of the bug, and it has been acknowledged. A spokesperson has promised that Apple will release the iOS update to fix the vulnerability within a week, but before that, you can only manually close FaceTime to avoid abuse by malicious people.
“We are aware of this problem and we have identified a fix that will be released in the software update later this week,” an Apple spokesperson said in a statement.
For example, 9to5Mac reported this issue, trying to reproduce the vulnerability. The FaceTime error works as follows:
Firstly, begin a FaceTime video call with a different iPhone. Swipe up from the bottom and then add people (or your phone number) to the call when you call or before the person answers. This will start a call with your group as well as the audio of the contact, even if they did not respond to it.
The news about this bug first spread on Twitter. Currently, iPhone users are advised to do the following to avoid this error:
Open “Settings” on your iOS device and choose FaceTime and then switch FaceTime to off.
