Rzkd Virus – Details

Rzkd is a destructive software working as typical ransomware. Michael Gillespie, the popular malware researcher, very first discovered this new name in the DJVU ransomware family.

Rzkd was created for the sole purpose to encrypt all popular file types. Rationally, as quickly as the file encryption is successfully achieved, the users are not able to get access to them. Rzkd virus adds its own “.rzkd” to all the encrypted data. For instance, the file “price_list.xls”, as soon as modified by Rzkd, will be entitled as “price_list.xls.rzkd”. When the encryption is accomplished, Rzkd puts its own special text file (_readme.txt) into all the folders that store the encrypted files.

The message specified by text file requesting for the random os extremely comparable to the alerts offered by other ransomware hazards coming from the DJVU family. The caution essentially shows that the files have been secured and the only solution to get access to it is to use an unique standalone key. Regretfully, this statement is definitely true.

The approach to secure the files utilized by Rzkd is not totally looked into. Nevertheless, there is no doubt that each computer system owner might be released a special decryption key, which is absolutely unique. It is exceptionally hard to recover the data without the suitable key in place.

“Don’t worry, you can return all your files!”, from _readme.txt message:

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

One more peculiarity of the Rzkd 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 scoundrels who have released the Rzkd infection into the world wide web. In order to obtain the key and restore the crucial data, the users are told to contact the scams by means of e-mail or by telegram and to pay the ransom in the amount of $980.

The message likewise states that the people need to call the Rzkd authors within 72 hours upon the minute of the information file encryption. The alert suggests that by doing so the people will acquire a 50% discount, therefore, the ransom quantity falls to $490.

No matter what the quantity of the ransom is, we strongly advise that you do not pay the ransom. There is no guarantee that these online criminals will keep their guarantees, so they might not care at all what the victims feel about the file encryption, even when the amount of the ransom is received into their accounts. Hence, paying ransom typically does not lead to a successful healing. So, the users might merely lose their money for nothing.

There are no applications that could break the Rzkd virus or restore the data at no cost. For that reason, the only proper choice is to bring back the data from possible backups (if available).
