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:
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.
