Kkll Virus Removal Guide (+Decrypt .kkll files)

Kkll Virus Ransomware

Kkll is a destructive software working as typical ransomware. Michael Gillespie, the widely known virus researcher, very first found this new name in the DJVU ransomware family.

Kkll was developed for the sole purpose to encrypt all popular file types. Realistically, as quickly as the encryption is successfully achieved, the users are unable to get access to them. Kkll virus includes its own “.kkll” to all the encrypted files. For instance, the file “price_list.xls”, once modified by Kkll, will be entitled as “price_list.xls.kkll”. Once the file encryption is accomplished, Kkll puts its own special text document (_readme.txt) into all the folders that keep the encrypted files.

The message specified by _readme.txt requesting the random os very similar to the notifications given by other ransomware dangers coming from the DJVU family. The warning generally indicates that the information has been encrypted and the only service to get access to it is to use a special standalone key. Regretfully, this statement is definitely real.

The method to encrypt the files used by Kkll is not entirely looked into. However, there is no doubt that each computer system owner may be provided a special decryption key, which is absolutely unique. It is incredibly tough to recover the data without the proper key in place.

“Don’t worry, you can return all your files!”, from text file message:

message from Kkll virus

One more peculiarity of the Kkll ransomware is that the users are not able to get access to the key. The decrypting key is hosted on an unique server under the complete control by the crooks who have actually released the Kkll infection into the web. In order to obtain the key and restore the essential data, the users are told to get in touch with the frauds by means of email or by telegram and to pay the ransom in the quantity of $980.

The message also says that individuals must get in touch with the Kkll authors within 72 hours upon the moment of the information encryption. The alert indicates that by doing so the people will get a 50% discount rate, for that reason, the ransom quantity falls to $490.

No matter what the quantity of the ransom is, we strongly encourage that you do not pay the ransom. There is no guarantee that these online scoundrels will keep their guarantees, so they might not care at all what the victims feel about the encryption, even when the quantity of the ransom is gotten into their accounts. Hence, paying ransom typically does not result in a successful healing. So, the users might simply lose their money for nothing.

Likewise, we prompt you not to call the frauds as they instruct. Do not transfer money into their wallets. There are no applications that could crack the Kkll virus or restore the information at no cost. For that reason, the only correct decision is to restore the data from possible backups (if readily available).
