One night in November of last year, Rayhan Ias was out at a bar in New York City when she saw a stranger talking to her friends.

My friend was talking to a few people.

I joined, my phone was in my hands,

and then the person said hi to me and then grabbed my phone and disappear.

The person had taken off with her phone and in a matter of minutes

Rayhahn's life was turned upside down.

Earlier this year, she sat down with our colleague Joanna Stern to tell her story.

So you realize your phone has been stolen.

What do you do next at the bar?

I log in to find my iPhone on my friend's phone right away.

And what happened?

I couldn't log in. It turned out the thief hadn't just taken her phone. He'd also

gotten a hold of her passcode. The series of typically four to six numbers you

use to unlock your phone.

And over the next couple of days,

Rayhan noticed thousands of dollars had disappeared from her bank account.

And that's when it hit me that this is way beyond just a petty phone theft and that's when I also

started getting worried what else is going to hit me.

Over the last year Joanna has heard from over 100 people like Rayhan, who fell victim to the same kind of crime,

a crime that revolves around the iPhone's pass code.

It's a scheme that's exposing security... that revolves around the iPhone's pass code.
