A random Telegram message arrives from a stranger.
“Hi. Someone is posting your picture and phone number in our channel. I think your information has been leaked. You should talk to this person.”
The stranger, seemingly helpful, asks the user to tap “Add Contact.” But as soon as the button is pressed, the user's phone number is shared — and a digital manhunt begins. With only that number, perpetrators scour social media accounts and KakaoTalk to identify the victim’s name, friends and family.
Then, without warning, the stranger turns hostile.
