Nzoq Virus Removal Guide (+Decrypt .nzoq files)

Nzoq – General Info

Nzoq is a malicious software functioning as common ransomware. Michael Gillespie, the popular malware researcher, very first discovered this new name in the DJVU ransomware family.

Nzoq was created for the sole purpose to encrypt all popular file types. Rationally, as quickly as the file encryption is successfully accomplished, the users are unable to get access to them. Nzoq virus includes its own “.nzoq” to all the encrypted data. For example, the file “price_list.xls”, once crypted by Nzoq, will be entitled as “price_list.xls.nzoq”. Once the encryption is accomplished, Nzoq puts its own unique text document (_readme.txt) into all the folders that keep the encrypted files.

The message specified by _readme.txt requesting for the random os very comparable to the notices given by other ransomware threats coming from the DJVU family. The warning essentially shows that the files have been secured and the only solution to get access to it is to use a special standalone key. Regretfully, this declaration is absolutely true.

The approach to secure the files utilized by Nzoq is not entirely investigated. However, there is no doubt that each computer owner might be issued a special decryption key, which is definitely distinct. It is incredibly tough to recuperate the information without the suitable type in location.

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

One more peculiarity of the Nzoq infection is that the users are unable to get access to the key. The decrypting key is hosted on an unique server under the total control by the scoundrels who have actually released the Nzoq infection into the web. In order to get the key and bring back the essential information, the users are told to contact the scams via e-mail or by telegram and to pay the ransom in the amount of $980.

The message likewise states that individuals need to contact the Nzoq authors within 72 hours upon the moment of the information file encryption. The alert shows that by doing so the people will obtain a 50% discount, for that reason, the ransom amount drops down to $490.

There are no applications that might split the Nzoq virus or restore the information at no charge. For that reason, the only correct decision is to restore the data from possible backups (if offered).
