Remove Nefartanulo Virus (.nefartanulo@protonmail.com Files Ransomware) – HiddenTear Ransomware

Nefartanulo Virus – Details

The Nefartanulo stands for a ransomware-type infection. The virus comes from the HiddenTear ransomware family. Nefartanulo was elaborated specifically to encrypt all major file types. When the file is encrypted people are unable to use them. Nefartanulo adds the “.nefartanulo@protonmail.com” extension for each file encrypted by it. For example, the file “myphoto.jpg“, as soon as encrypted by Nefartanulo, will be renamed into “myphoto.jpg.nefartanulo@protonmail.com“. As soon as the encryption is finished, Nefartanulo places a special text file into every folder containing the encrypted data.

The message given by Nefartanulo text file asking for the ransom is definitely the same as the statements given by other ransomware virus representatives coming from the HiddenTear family. It literally points out that the information is encrypted and that the only way to restore it is to use a an unique decryption key. Unfortunately, this is definitely true. The kind of cryptography mechanism used by Nefartanulo is still not properly examined. Still, it is definitely particular that each victim might be given the specific decryption key, which is absolutely distinct. It is impossible to restore the files without the key available.

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

However, irrespective of the asked for quantity, people must keep away from paying the ransom. Cyber frauds are not fair, so they tend to completely disregard 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 outcome and people just lose their money for 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 Nefartanulo ransomware and to recover the data data free of charge. Thus, the just best decision is to recover the lost data from the available backup.
