Ransomware, malware that encrypts systems and then asks for a ransom to decrypt files and systems, has become more prevalent in recent years. In fact, two of 2017’s major cyberattacks were malware: WannaCry in May, followed by Petya in July. CryptoLocker and CryptoWall were the most prominent malware for PCs before WannaCry and Petya, and together, they generated around $21 million dollars between 2013 and 2015.
