When JigSaw ransomware was initially detected, it locked the screen of infected users’ computers displaying a countdown timer. The ransomware scans for and encrypts over 120 types of files on the compromised computers it has infected. Users were left with nothing but to pay a large ransom amount usually varying in the hundreds of dollars. The worst period of Jigsaw ransomware was when it was released for sale in the deep web in the form of ransomware as a service (RaaS). The virus then exploded with multiple variants and became even widespread, possibly making its creators even richer than before. Luckily for users, how there has been a decryptor released which can recover the files encoded by JigSaw ransomware. We have decided to make instructions and assist users to decode any important files encrypted by Jigsaw.
Jigsaw Ransomware – More Information About It
Initially when it was released, Jigsaw ransomware displayed a wallpaper from the famous movie Jigsaw:
The first variant wanted users to pay the ransom amount of 150 US dollars to gain access to their computer and their files back. When it was released, Jigsaw demonstrated a lot of skills and tricks up in its sleeve. The primary characteristic for it was the virus was highly customizable, which became evident with the other variants of Jigsaw which came out shortly after:
What became typical for the Jigsaw variants was the rather interesting Anonymous theme on most of them and the increasing amount of ransom payoff needed. One variant even required infected users to pay the minimum sum of approximately 5000$ which is outrageous. Users were strongly advised not to pay any ransom and fund the cyber-criminals to release yet another variant.
