Remove .nz Virus (.nz Files Ransomware) – MedusaLocker Ransomware

.nz Virus Ransomware

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

The message given by .nz text file requesting for the ransom is absolutely the same as the statements given by other ransomware representatives belonging to the MedusaLocker clan. It literally discusses that the info is encrypted and that the only way to restore it is to use a a special decryption key. Unfortunately, this is definitely true. The type of cryptography mechanism applied by .nz is still not properly examined. Still, it is absolutely specific that each victim may be given the specific decryption key, which is absolutely distinct. It is difficult to bring back the files without the key available.

Another technique of .nz is that the victims cannot gain access to the key. The key is saved on a specific server run by the frauds connected with .nz ransomware. To get the key and recover the important info people need to pay the ransom.

However, regardless of the asked for quantity, people must stay away from paying the virus. Cyber frauds are not fair, so they tend to entirely disregard what their victims feel about the issue, even when the payment reaches their pockets. This is why paying the ransom generally does not provide any positive outcome and people just lose their money for absolutely nothing.

We highly recommend that you do not contact these crooks and absolutely do not transfer money into their accounts. It is said to admit that there are no utilities able to crack .nz ransomware and to recover the information data totally free. Hence, the only best decision is to recover the lost data from the available backup.

Remember that the web is now overwhelmed with threats that look similar to .nz ransomware. Malicious programs of such kind are usually elaborated to encrypt essential information and to state the demand before the user to pay the ransom. The peculiarity of all such ransomware threats is that all apply a similar algorithm to generate the special decryption key for information decryption.

Therefore, as long as the ransomware is still being developed or has some hidden bugs, by hand recovering the information is just not feasible. The only method to avoid the loss of your crucial data is to frequently create backups of your important information.

If you save your backup files on your common system they may be encrypted in addition to other files, so it’s absolutely not a good storage location.
