Zdfv – Ransomware
Zdfv is a destructive software application functioning as common ransomware. Michael Gillespie, the popular malware researcher, first found this new name in the DJVU ransomware family.
Zdfv was created for the sole function to encrypt all popular file types. Realistically, as soon as the file encryption is successfully accomplished, the users are not able to get access to them. Zdfv virus includes its own “.zdfv” to all the encrypted data. For example, the file “price_list.xls”, once crypted by Zdfv, will be titled as “price_list.xls.zdfv”. Once the encryption is achieved, Zdfv puts its own special text file (_readme.txt) into all the folders that keep the encrypted files.
The message stated by document asking for the random os very comparable to the notices given by other ransomware risks belonging to the DJVU family. The warning essentially shows that the information has been encrypted and the only solution to get access to it is to use a special standalone key. Regretfully, this declaration is absolutely real.
The technique to encrypt the files utilized by Zdfv is not completely investigated. However, there is no doubt that each computer owner might be provided an unique decryption key, which is absolutely unique. It is exceptionally difficult to recover the information without the suitable type in location.
“Don’t worry, you can return all your files!”, from text file message:
One more peculiarity of the Zdfv virus 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 actually introduced the Zdfv infection into the web. In order to acquire the key and bring back the essential information, the users are informed to contact the scams by means of e-mail or by telegram and to pay the ransom in the quantity of $980.
The message also says that individuals should contact the Zdfv authors within 72 hours upon the moment of the data encryption. The alert shows that by doing so the people will get a 50% discount rate, for that reason, the ransom quantity 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 assurance that these online crooks will keep their guarantees, so they might not care at all what the victims feel about the encryption, even when the amount of the ransom is received into their accounts. Thus, paying ransom frequently does not lead to a successful healing. So, the users might just lose their money for absolutely nothing.
Similarly, we prompt you not to contact the frauds as they instruct. Do not move money into their wallets. There are no applications that could split the Zdfv virus or bring back the information for free. Therefore, the only proper choice is to restore the data from possible backups (if available).
