Novasof Virus Removal Guide (+Decrypt .novasof files) – DJVU Ransomware

Novasof – General Info

The Novasof stands for a ransomware-type infection. Initially, it was revealed by Michael Gillespie. The virus comes from the DJVU ransomware family. Novasof was elaborated particularly to encrypt all major file types. When the file is encrypted people are not able to use them. Novasof adds the “.novasof” extension for each file encrypted by it. For example, the file “myphoto.jpg“, as soon as encrypted by Novasof, will be renamed into “myphoto.jpg.novasof. As quickly as the encryption is finished, Novasof places a special text file (such as “_readme.txt“) into every folder containing the encrypted data.

The message given by Novasof text file asking for the ransom is absolutely the same as the statements given by other ransomware representatives belonging to the DJVU type. It actually points out that the info is encrypted and that the only way to bring back it is to use a an unique decryption key. Unfortunately, this is absolutely true. The sort of cryptography mechanism used by Novasof is still not appropriately examined. Still, it is absolutely certain that each victim might be given the specific decryption key, which is totally unique. It is difficult to restore the files without the key available.

“Don’t worry, you can return all your files!”, Novasof message:

Don't worry, you can return all your files! virus

Another technique of Novasof is that the victims cannot gain access to the key. The key is kept on a specific server run by the frauds connected with Novasof ransomware. To get the key and recover the important information people have to pay the ransom, which amounts to $980. To get the payment details users are advised to contact the frauds through e-mail or telegram. The alert also indicates that the users require to contact the Novasof developers within 72 hours after the encryption occurred. The message says that doing so users will get a 50% discount, so the ransom amount will fall to $490.

Nonetheless, irrespective of the asked for amount, people need to stay away from paying the ransom. Cyber frauds are unfair, so they tend to entirely ignore what their victims feel about the issue, even when the payment reaches their pockets. This is why paying the ransom usually does not provide any positive result and people just lose their money for absolutely nothing.

We strongly recommend 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 Novasof ransomware and to recover the information data totally free. Therefore, the just best decision is to recover the lost data from the available backup.
