Nitz Virus – Details

Nitz is a malicious software application working as typical ransomware. Michael Gillespie, the well-known virus researcher, very first found this new name in the DJVU ransomware family.

Nitz was created for the sole function to encrypt all popular file types. Rationally, as soon as the encryption is successfully accomplished, the users are not able to get access to them. Nitz ransomware adds its own “.nitz” to all the encrypted data. For instance, the file “price_list.xls”, once modified by Nitz, will be titled as “price_list.xls.nitz”. Once the file encryption is achieved, Nitz puts its own distinct text file (_readme.txt) into all the folders that keep the encrypted files.

The message specified by document asking for the random os very comparable to the notices offered by other ransomware threats coming from the DJVU family. The caution basically shows that the files have been encrypted and the only service to get access to it is to use a special standalone key. Regretfully, this declaration is absolutely real.

The approach to encrypt the files used by Nitz is not completely looked into. Nevertheless, there is no doubt that each computer system owner may be provided a special decryption key, which is definitely special. It is extremely difficult to recover the data without the proper type in place.

“Don’t worry, you can return all your files!”, from text file message:

Don't worry, you can return all your files! virus

One more peculiarity of the Nitz virus is that the users are not able to get access to the key. The decrypting key is hosted on an unique server under the total control by the criminals who have actually introduced the Nitz virus into the internet. In order to get the key and restore the essential information, the users are told to contact the frauds through email or by telegram and to pay the ransom in the amount of $980.

The message also says that individuals ought to get in touch with the Nitz authors within 72 hours upon the minute of the data encryption. The alert suggests that by doing so individuals will obtain a 50% discount rate, therefore, the ransom amount drops down to $490.

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

Likewise, we advise you not to contact the scams as they advise. Do not transfer money into their wallets. There are no applications that could crack the Nitz virus or bring back the data at no cost. For that reason, the only correct decision is to restore the information from possible backups (if offered).
