Ransomware is one of the most popular dev toys of 2,017. Rensenware encrypts your files and asks you to reach a score of 0.2 billion in a game of TH12 fantastic objects, in lunatic mode. Don't lose, your files are at stake. You may lose more than just a game.
(Luckily there is a cheat that you can use to beat the game instantly and free your files, unless it's your work computer and you don't mind spending a lifetime trying to get that high score)
