Jigsaw Virus – DetailsThe Jigsaw mean a ransomware-type infection. The infection comes from the Jigsaw ransomware family. Jigsaw was elaborated specifically to encrypt all major file types. Once the file is encrypted people are unable to use them. Jigsaw adds the “.kwkc” extension for each file encrypted by it. For example, the file “myphoto.jpg“, as soon as encrypted by Jigsaw, will be renamed into “myphoto.jpg.kwkc“. As quickly as the encryption is finished, Jigsaw places a special text file into every folder containing the encrypted data.
The message given by Jigsaw text file requesting the ransom is absolutely the like the statements given by other ransomware virus representatives coming from the Jigsaw clan. It literally points out that the information is encrypted and that the only way to bring back it is to use a a special decryption key. Sadly, this is absolutely true. The sort of cryptography mechanism applied by Jigsaw is still not properly examined. Still, it is definitely particular that each victim might be given the specific decryption key, which is totally distinct. It is difficult to bring back the files without the key available.
Another trick of Jigsaw is that the victims cannot gain access to the key. The key is stored on a particular server run by the frauds connected with Jigsaw ransomware. To get the key and recover the important info people need to pay the ransom.
However, irrespective of the requested amount, people must keep away from paying the ransom. Cyber frauds are unfair, so they tend to entirely ignore what their victims feel about the problem, even when the payment reaches their pockets. This is why paying the ransom normally does not give any positive outcome and people just waste their money for absolutely nothing.
We strongly encourage that you do not contact these crooks and definitely do not transfer money into their accounts. It is said to admit that there are no utilities able to crack Jigsaw ransomware and to recover the information data for free.
