Zfdv – General Info
Zfdv is a malicious software application working as typical ransomware. Michael Gillespie, the widely known malware researcher, very first found this new name in the DJVU ransomware family.
Zfdv was created for the sole purpose 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. Zfdv virus includes its own “.zfdv” to all the encrypted data. For example, the file “price_list.xls”, as soon as crypted by Zfdv, will be entitled as “price_list.xls.zfdv”. When the file encryption is accomplished, Zfdv puts its own unique text document (_readme.txt) into all the folders that keep the encrypted files.
The alert stated by _readme.txt requesting for the random os extremely similar to the notifications offered by other ransomware risks belonging to the DJVU family. The warning generally indicates that the files have been encrypted and the only option to get access to it is to use a special standalone key. Regretfully, this declaration is definitely true.
The method to secure the files utilized by Zfdv is not completely investigated. Nevertheless, there is no doubt that each computer system owner may be provided an unique decryption key, which is definitely distinct. It is extremely tough to recover the data without the proper key in place.
“Don’t worry, you can return all your files!”, from text file message:
One more peculiarity of the Zfdv infection 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 Zfdv ransomware into the world wide web. In order to obtain the key and restore the crucial data, the users are told to get in touch with the frauds via e-mail or by telegram and to pay the ransom in the amount of $980.
The message also states that the people need to get in touch with the Zfdv authors within 72 hours upon the minute of the data file encryption. The alert indicates that by doing so individuals will get a 50% discount rate, therefore, the ransom amount falls to $490.
