“Popcorn Time” is the most dangerous ransomware that offers free decryption if you infect two other users and they pay. Initially it encrypts and locks away a user’s files and data by infecting the device. After that, it flashes a message on the infected screen to pay the ransom. It lets off a victim who is not willing to pay the ransom for the recovery of the encrypted files; with the condition that victim must infect two other users. If the two new victims decide to pay up or infect other devices, the assisting victim is given the decryption key for the locked files for free.
