Nlah Virus Removal Guide (+Decrypt .nlah files)

Nlah Virus – Details

Nlah is a malicious software application working as common ransomware. Michael Gillespie, the widely known malware researcher, very first discovered this new name in the DJVU ransomware family.

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

The message stated by _readme.txt requesting the random os very comparable to the notifications provided by other ransomware dangers belonging to the DJVU family. The warning essentially shows that the information has been secured and the only service to get access to it is to use a special standalone key. Regretfully, this declaration is definitely real.

The technique to encrypt the files used by Nlah is not totally investigated. However, there is no doubt that each computer owner might be issued an unique decryption key, which is absolutely distinct. It is exceptionally tough to recover the data without the proper key in place.

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

message from Nlah virus

One more peculiarity of the Nlah virus 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 criminals who have actually released the Nlah ransomware into the internet. In order to obtain the key and restore the essential information, the users are told to get in touch with the scams via e-mail or by telegram and to pay the ransom in the amount of $980.

The message also says that the people ought to contact the Nlah authors within 72 hours upon the moment of the information encryption. The alert shows that by doing so the people will obtain 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 guarantee that these online criminals will keep their guarantees, so they might not care at all what the victims feel about the encryption, even when the quantity of the ransom is gotten into their accounts. Hence, paying ransom frequently does not lead to an effective healing. So, the users may 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 might split the Nlah virus or restore the information at no cost. Therefore, the only correct choice is to bring back the information from possible backups (if offered).
