Zpww – Ransomware
Zpww is a malicious software working as common ransomware. Michael Gillespie, the widely known virus researcher, first discovered this new name in the DJVU ransomware family.
Zpww was created for the sole function to encrypt all popular file types. Rationally, as quickly as the file encryption is effectively achieved, the users are not able to get access to them. Zpww ransomware includes its own “.zpww” to all the encrypted data. For instance, the file “price_list.xls”, once modified by Zpww, will be entitled as “price_list.xls.zpww”. When the encryption is accomplished, Zpww puts its own special text file (_readme.txt) into all the folders that keep the encrypted files.
The message stated by _readme.txt requesting for the random os very similar to the alerts offered by other ransomware hazards belonging to the DJVU family. The warning essentially shows that the files have been encrypted and the only service to get access to it is to use a distinct standalone key. Regretfully, this statement is definitely true.
The method to secure the files used by Zpww is not completely researched. However, there is no doubt that each computer system owner might be issued a special decryption key, which is definitely special. It is incredibly tough to recover the information without the appropriate type in place.
“Don’t worry, you can return all your files!”, from _readme.txt message:
One more peculiarity of the Zpww ransomware is that the users are unable to get access to the key. The decrypting key is hosted on an unique server under the complete control by the criminals who have released the Zpww ransomware into the world wide web. In order to acquire the key and bring back the crucial data, the users are told to get in touch with the scams through e-mail or by telegram and to pay the ransom in the quantity of $980.
The message also states that the people need to get in touch with the Zpww authors within 72 hours upon the minute of the information file encryption. The alert indicates that by doing so the people will acquire a 50% discount, for that reason, the ransom amount drops down to $490.

No matter what the amount of the ransom is, we highly encourage that you do not pay the ransom. There is no assurance that these online scoundrels will keep their pledges, 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 often does not lead to an effective healing. So, the users might just lose their money for absolutely nothing.
Similarly, we advise you not to call the scams as they advise. Do not transfer money into their wallets. There are no applications that might break the Zpww virus or restore the data at no cost. Therefore, the only appropriate decision is to restore the data from possible backups (if available).
