Consider this scenario ...
You get a Facebook Messenger note from an old buddy. He says, "I love that picture of your old Camaro you posted! Check out this one I just saw today!"
You can hardly wait to see the car he mentioned, so you click the picture, and sure enough, it's a Camaro.
Almost immediately, your computer starts acting funny. It's really slow, and sometimes won't open files, or go to web pages you select. Your friends start asking you why you are sending them spam Messenger texts.
You suspect these may be related, so you contact your friend to ask about the picture he sent. "I didn't send you a picture of a Camaro!", he insists. "Sure you did. You even mentioned the picture of my first car that I posted a couple days ago, that you liked."
"I remember liking that picture of your first car, but I didn't send you any pictures today!"
Then who the hell did?
A North Korean bot did.
How did is know I loved Camaros?
Because you told it, when it asked about your first car. And when it saw that your friend 'liked' your comment about your Camaro, so it knew just who to pretend to be to get you to click the link that would surrender control of your computer.
All these quizzes seem fun. But if a total stranger came up to you on the street and asked you these same questions, would you just answer them, or would you keep on walking?
