Nnuz Virus – Details

Nnuz was created for the sole function to encrypt all popular file types. Rationally, as quickly as the encryption is successfully accomplished, the users are unable to get access to them. Nnuz ransomware includes its own “.nnuz” to all the encrypted files. For example, the file “price_list.xls”, once crypted by Nnuz, will be titled as “price_list.xls.nnuz”. When the encryption is accomplished, Nnuz puts its own unique text document (_readme.txt) into all the folders that keep the encrypted files.
The alert specified by text file requesting the random os really similar to the alerts offered by other ransomware risks belonging to the DJVU family. The caution basically indicates that the data has been encrypted and the only solution to get access to it is to use a distinct standalone key. Regretfully, this declaration is absolutely true.
The method to secure the files used by Nnuz is not entirely investigated. Nevertheless, there is no doubt that each computer owner might be provided an unique decryption key, which is definitely unique. It is exceptionally hard to recuperate the data without the proper key in location.
“Don’t worry, you can return all your files!”, from text file message:
One more peculiarity of the Nnuz ransomware 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 crooks who have launched the Nnuz ransomware into the world wide web. In order to get the key and bring back the essential data, the users are told to connect with the frauds via e-mail or by telegram and to pay the ransom in the amount of $980.
The message likewise states that individuals need to get in touch with the Nnuz authors within 72 hours upon the moment of the data encryption. The alert shows that by doing so individuals will get a 50% discount, therefore, the ransom amount falls to $490.
