You were doing your homework, searching for information on the internet, when you opened a PDF, your PC got blocked and shut down.

When you turn on your PC, you find a red screen with the words: "All your files will be deleted if you don't pay 500$ ".

There was also a countdown of 24 hours and a link that led you to a page where you could pay, and also a chat with an unknown user, probably the one who hacked you.

You receive a message from that chat.

CrazyCrash: " You look cute in those pajamas ;) "

That unknown hacker has access to your webcam.
