Nuhb Virus Removal Guide (+Decrypt .nuhb files)

Nuhb Virus – Details

Nuhb is a destructive software working as common ransomware. Michael Gillespie, the well-known malware researcher, very first found this new name in the DJVU ransomware family.

Nuhb was developed for the sole purpose to encrypt all popular file types. Realistically, as soon as the encryption is successfully accomplished, the users are not able to get access to them. Nuhb virus adds its own “.nuhb” to all the encrypted files. For example, the file “price_list.xls”, as soon as modified by Nuhb, will be entitled as “price_list.xls.nuhb”. Once the file encryption is achieved, Nuhb puts its own unique text file (_readme.txt) into all the folders that store the encrypted files.

The message specified by _readme.txt asking for the random os extremely comparable to the notifications provided by other ransomware dangers belonging to the DJVU family. The caution essentially indicates that the data has been secured and the only solution to get access to it is to use an unique standalone key. Regretfully, this declaration is definitely real.

The technique to encrypt the files utilized by Nuhb is not entirely investigated. Nevertheless, there is no doubt that each computer system owner might be provided a special decryption key, which is absolutely special. It is incredibly difficult to recover the information without the appropriate key in location.

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

One more peculiarity of the Nuhb infection is that the users are not able to get access to the key. The decrypting key is hosted on a special server under the total control by the crooks who have actually introduced the Nuhb infection into the internet. In order to obtain the key and bring back the essential data, the users are told to connect with the scams via email or by telegram and to pay the ransom in the quantity of $980.

The message likewise states that the people ought to get in touch with the Nuhb authors within 72 hours upon the moment of the data file encryption. The alert indicates that by doing so individuals will get a 50% discount rate, for that reason, the ransom quantity 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 guarantee that these online criminals will keep their pledges, so they might not care at all what the victims feel about the encryption, even when the quantity of the ransom is received into their accounts. Hence, paying ransom often does not lead to an effective healing. So, the users might merely lose their money for absolutely nothing.

Similarly, we advise you not to get in touch with the scams as they advise. Do not transfer loan into their wallets. There are no applications that could split the Nuhb virus or bring back the information for free. Therefore, the only right choice is to bring back the data from possible backups (if available).
