Npsk Virus Removal Guide (+Decrypt .npsk files)

Npsk Virus – Details

Npsk is a malicious software application functioning as common ransomware. Michael Gillespie, the popular virus researcher, first discovered this new name in the DJVU ransomware family.

Npsk was developed for the sole purpose to encrypt all popular file types. Logically, as soon as the file encryption is successfully achieved, the users are not able to get access to them. Npsk virus adds its own “.npsk” to all the encrypted files. For instance, the file “price_list.xls”, as soon as modified by Npsk, will be titled as “price_list.xls.npsk”. Once the file encryption is achieved, Npsk puts its own special text document (_readme.txt) into all the folders that save the encrypted files.

The alert mentioned by _readme.txt requesting for the random os very similar to the notices given by other ransomware dangers coming from the DJVU family. The warning generally shows that the information has been secured and the only service to get access to it is to use a unique standalone key. Regretfully, this statement is absolutely true.

The technique to encrypt the files used by Npsk is not completely looked into. Nevertheless, there is no doubt that each computer owner might be provided a special decryption key, which is definitely unique. It is extremely hard to recuperate the information without the proper type in location.

“Don’t worry, you can return all your files!”, from _readme.txt message:

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

One more peculiarity of the Npsk ransomware is that the users are not able to get access to the key. The decrypting key is hosted on an unique server under the complete control by the scoundrels who have actually launched the Npsk infection into the world wide web. In order to get the key and restore the crucial data, the users are informed to contact the frauds through email or by telegram and to pay the ransom in the amount of $980.

The message also says that the people need to get in touch with the Npsk authors within 72 hours upon the moment of the data encryption. The alert indicates that by doing so the people will acquire a 50% discount, therefore, the ransom amount drops down to $490.

No matter what the amount of the ransom is, we highly encourage that you do not pay the ransom. There is no assurance that these online scoundrels will keep their promises, so they might not care at all what the victims feel about the file encryption, even when the quantity of the ransom is received into their accounts. Thus, paying ransom often does not result in a successful recovery. So, the users might just lose their money for absolutely nothing.

Likewise, we prompt you not to call the frauds as they instruct. Do not transfer cash into their wallets. There are no applications that could split the Npsk virus or restore the information at no charge. For that reason, the only appropriate decision is to restore the data from possible backups (if available).
