You’re most likely to encounter AirDrop in a public space when you’re blocking some random stranger from sending you a weird picture or greeting. But if you ever need to toss a file between devices. Maybe that funny picture you just took of your friends at a bar, wait until you’re home, for security’s sake.
According to recent reports, an attacker can already sniff out more details about you than you’re probably willing to give out simply because you have Bluetooth activated on your device. If you fire up AirDrop or use iOS handy feature that allows you to share a Wi-Fi password to a friend, an attacker could also extract your full phone number.
