Nesa Virus Removal Guide (+Decrypt .nesa files)

Nesa Virus – Details

Nesa is a destructive software application working as common ransomware. Michael Gillespie, the widely known malware researcher, first found this new name in the DJVU ransomware family.

Nesa was created for the sole function to encrypt all popular file types. Rationally, as soon as the encryption is successfully achieved, the users are unable to get access to them. Nesa ransomware includes its own “.nesa” to all the encrypted files. For instance, the file “price_list.xls”, as soon as modified by Nesa, will be entitled as “price_list.xls.nesa”. When the encryption is accomplished, Nesa puts its own special text file (_readme.txt) into all the folders that store the encrypted files.

The message mentioned by _readme.txt requesting the random os really similar to the alerts provided by other ransomware dangers belonging to the DJVU family. The caution basically indicates that the files have been secured and the only service to get access to it is to use a distinct standalone key. Regretfully, this declaration is definitely true.

The technique to encrypt the files used by Nesa is not completely researched. Nevertheless, there is no doubt that each computer system owner might be provided an unique decryption key, which is absolutely distinct. It is exceptionally tough to recuperate the data without the proper type in location.

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

One more peculiarity of the Nesa ransomware is that the users are not able to get access to the key. The decrypting key is hosted on a special server under the complete control by the crooks who have launched the Nesa ransomware into the world wide web. In order to get the key and restore the essential information, the users are told to get in touch with the scams by means of email or by telegram and to pay the ransom in the amount of $980.

The message also states that individuals should get in touch with the Nesa authors within 72 hours upon the minute of the data file encryption. The alert shows that by doing so individuals will acquire a 50% discount rate, for that reason, the ransom amount falls to $490.

No matter what the amount of the ransom is, we highly advise that you do not pay the ransom. There is no warranty that these online criminals will keep their promises, so they might not care at all what the victims feel about the file encryption, even when the amount of the ransom is received into their accounts. For this reason, paying ransom typically does not result in an effective recovery. So, the users might simply lose their money for nothing.

Likewise, we advise you not to contact the frauds as they instruct. Do not move money into their wallets. There are no applications that could crack the Nesa ransomware or bring back the information at no charge. Therefore, the only appropriate decision is to bring back the information from possible backups (if offered).
