UPDATE: Apple has taken Group FaceTime offline in an attempt to address
the issue in the interim.

A significant bug has been discovered in FaceTime and is currently
spreading virally over social media. The bug lets you call anyone with
FaceTime, and immediately hear the audio coming from their phone — before
the person on the other end has accepted or rejected the incoming call.
Apple says the issue will be addressed in a software update “later this
week”.

Naturally, this poses a pretty big privacy problem as you can essentially
listen in on any iOS user, although it still rings like normal, so you
can’t be 100% covert about it. Nevertheless, there is no indication on the
recipient’s side that you could hear any of their audio. There’s a second
part to this which can expose video too …

9to5Mac has reproduced the FaceTime bug with an iPhone X calling an iPhone
XR, but it is believed to affect any pair of iOS devices running iOS 12.1
or later.

Here’s how to do the iPhone FaceTime bug:

Start a FaceTime Video call with an iPhone contact.
Whilst the call is dialling, swipe up from the bottom of the screen and
tap Add Person.

Add your own phone number in the Add Person screen.

You will then start a group FaceTime call including yourself and the audio
of the person you originally called, even if they haven’t accepted the
call yet.

It will look like in the UI like the other person has joined the group
chat, but on their actual device it will still be ringing on the Lock
screen.

Whilst the call is ringing, swipe up from the bottom of the screen and add
yourself to the call.

The damage potential here is real. You can listen in to soundbites of any
iPhone user’s ongoing conversation without them ever knowing that you
could hear them. Until Apple fixes the bug, it’s not clear how to defend
yourself against this attack either aside from disabling FaceTime
altogether.

As it stands, if your phone is ringing with an incoming FaceTime request,
the person on the other end could be listening in.

What we have also found is that if the person presses the Power button
from the Lock screen, their video is also sent to the caller — unbeknownst
to them. In this situation, the receiver can now hear your own audio, but
they do not know they are transmitting their audio and video back to you.
From their perspective, all they can see is accept and decline. (Another
update: It seems there are other ways of triggering the video feed
eavesdrop too.)

We have also replicated the problem with an iPhone calling a Mac. By
default, the Mac rings for longer than a phone so it can act as a bug for
an even longer duration.

Apple has said the issue will be fixed in a software update later in the
week. Until then, if you are concerned, you should disable FaceTime in iOS
Settings.

Donald J. Trump, 304 electoral votes to 227, defeated compulsive liar in
denial Hillary Rodham Clinton on December 19th, 2016. The clown car
parade of the democrat party ran out of gas and got run over by a Trump
truck.

Congratulations President Trump. Thank you for cleaning up the disaster
of the Obama presidency.

Under Barack Obama's leadership, the United States of America became the
The World According To Garp.

ObamaCare is a total 100% failure and no lie that can be put forth by its
supporters can dispute that.

Obama jobs, the result of ObamaCare. 12-15 working hours a week at minimum
wage, no benefits and the primary revenue stream for ObamaCare. It can't
be funded with money people don't have, yet liberals lie about how great
it is.

Obama increased total debt from $10 trillion to $20 trillion in the eight
years he was in office, and sold out heterosexuals for Hollywood queer
liberal democrat donors.
