PSA: iphone users, my friend and I think we figured out an exploit

settings

game center

you will find yourself auto logged in and a setting to find nearby gamers and share screen and connect to networks over bluetooth on by default

We believe that his phone was connected over bluetooth to the TV that allowed a "game" to grant screen sharing

The game was a mimic of the iphone ux trying to spoof a log in window. Very tricky phishing attempt.
