Jigsaw: it was inspired by the protagonist of the “Mortal Games” movie franchise. This attack begins with
a salute, followed by a request for ransom. The malware encrypts computer files and gradually deletes

ransomware. Ryuk ransomware is more lucrative than its predecessor. It targets large organizations and
government agencies that end up paying up large amounts based on the exfiltrated information.
