Nbes – Ransomware

Nbes is a malicious software working as common ransomware. Michael Gillespie, the popular malware researcher, first found this new name in the DJVU ransomware family.

Nbes was created for the sole function to encrypt all popular file types. Rationally, as soon as the file encryption is effectively achieved, the users are not able to get access to them. Nbes ransomware includes its own “.nbes” to all the encrypted files. For instance, the file “price_list.xls”, when crypted by Nbes, will be entitled as “price_list.xls.nbes”. As soon as the encryption is accomplished, Nbes puts its own unique text document (_readme.txt) into all the folders that store the encrypted files.

The message specified by _readme.txt asking for the random os extremely similar to the notifications provided by other ransomware dangers coming from the DJVU family. The caution generally indicates that the files have been encrypted and the only option to get access to it is to use a special standalone key. Regretfully, this declaration is definitely real.

The technique to secure the files utilized by Nbes is not entirely investigated. However, there is no doubt that each computer owner may be released an unique decryption key, which is definitely special. It is incredibly tough to recover the information without the appropriate 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 Nbes 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 introduced the Nbes virus into the internet. In order to get the key and restore the essential data, the users are told to contact the scams through email or by telegram and to pay the ransom in the quantity of $980.

The message likewise says that the people need to call the Nbes authors within 72 hours upon the minute of the data file encryption. The alert shows that by doing so individuals will obtain a 50% discount, therefore, the ransom quantity falls to $490.

No matter what the quantity of the ransom is, we highly encourage that you do not pay the ransom. There is no warranty that these online scoundrels will keep their guarantees, so they might not care at all what the victims feel about the encryption, even when the amount of the ransom is received into their accounts. For this reason, paying ransom often does not lead to an effective healing. So, the users may merely lose their money for absolutely nothing.

Similarly, we prompt you not to get in touch with the frauds as they advise. Do not transfer cash into their wallets. There are no applications that could crack the Nbes ransomware or bring back the data at no charge. For that reason, the only proper decision is to restore the information from possible backups (if offered).
