JigSaw Virus Ransomware

The JigSaw mean a ransomware-type infection. JigSaw was elaborated specifically to encrypt all major file types. Once the file is encrypted people are not able to use them. JigSaw adds the “.exe” 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.exe“. 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 for the ransom is definitely the same as the statements given by other ransomware virus representatives. It actually mentions that the info is encrypted and that the only way to bring back it is to use a a distinct decryption key. Unfortunately, this is definitely true. The type of cryptography mechanism used by JigSaw is still not properly examined. Still, it is absolutely particular that each victim may be given the specific decryption key, which is completely unique. It is difficult to bring back the files without the key available.

Another trick of JigSaw is that the victims cannot get to the key. The key is stored on a specific server run by the frauds related to JigSaw ransomware. To get the key and recover the important information people need to pay the ransom.

However, irrespective of the asked for amount, people need to keep away from paying the virus. Cyber frauds are not fair, so they tend to totally ignore what their victims feel about the issue, even when the payment reaches their pockets. This is why paying the ransom typically does not provide any positive result and people just lose their money for nothing.

We strongly encourage that you do not contact these crooks and certainly 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 data data for free.
