Jigsaw (ransomware)

Jigsaw is a form of encrypting ransomware malware created in 2016. It was initially titled "BitcoinBlackmailer", but later came to be known as "Jigsaw" due to featuring an image of Billy the Puppet from the Saw film franchise. The malware encrypts computer files and gradually deletes them, demanding payment of a ransom to decrypt the files and halt the deletion.

History
Jigsaw was designed in April 2016 and released a week after creation. Jigsaw is activated if a user downloads the malware program which will encrypt all user files and master boot record. Following this, a popup featuring Billy the Puppet will appear with the ransom demand in the style of ''Saw's'' Jigsaw (one version including the "I want to play a game" line from the franchise) for Bitcoin in exchange for decrypting the files. Following this for each hour without a ransom payment, the amount of files deleted is exponentially increased each time from a few hundred to thousands of files until the computer is wiped after 72 hours. Jigsaw activates purporting to be either Firefox or Dropbox in the task manager. == Reception ==
