The malware dubbed "Popcorn Time" locks your Windows computer's files with strong AES-256 encryption, until you a pay a ransom of one bitcoin (or $780 at the time of writing).
But this ransomware comes with a twist.
The lock screen will let victims unlock their files the "nasty way" by sharing a link with two other people -- presumably ones the victim doesn't like. If they become infected and pay, then the original victim will receive a free decryption key.
Otherwise, infected users have seven days to pay the bitcoin ransom to an anonymous wallet.
