Nerz was created for the sole purpose to encrypt all popular file types. Realistically, as soon as the encryption is successfully accomplished, the users are unable to get access to them. Nerz ransomware adds its own “.nerz” to all the encrypted data. For instance, the file “price_list.xls”, when crypted by Nerz, will be entitled as “price_list.xls.nerz”. When the encryption is achieved, Nerz puts its own unique text file (_readme.txt) into all the folders that keep the encrypted files.
The message stated by _readme.txt requesting the random os very similar to the notifications offered by other ransomware risks coming from the DJVU family. The caution basically shows that the files have been encrypted and the only option to get access to it is to use a special standalone key. Regretfully, this statement is definitely true.
The technique to secure the files used by Nerz is not entirely investigated. However, there is no doubt that each computer system owner may be issued an unique decryption key, which is absolutely distinct. It is incredibly difficult to recuperate the information without the suitable key in place.
“Don’t worry, you can return all your files!”, from text file message:
One more peculiarity of the Nerz 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 complete control by the crooks who have actually introduced the Nerz infection into the web. In order to obtain the key and bring back the essential data, the users are told to contact the frauds by means of 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 Nerz authors within 72 hours upon the moment of the information encryption. The alert indicates that by doing so individuals will get a 50% discount, therefore, the ransom quantity drops down to $490.
