Over the weekend, ransomware infected computers in tens of thousands of locations around the world, including hospitals and telecom companies. The software used in the massive attack, a variant¹ of "Wanna Cry," was spread via email, and demanded 300 dollars worth of Bitcoin to release files and information.
