Kiop Virus – Details

Kiop is a harmful software working as common ransomware. Michael Gillespie, the widely known malware researcher, first found this new name in the DJVU ransomware family.

Kiop was developed for the sole purpose to encrypt all popular file types. Rationally, as quickly as the encryption is effectively accomplished, the users are unable to get access to them. Kiop ransomware includes its own “.kiop” to all the encrypted data. For instance, the file “price_list.xls”, as soon as crypted by Kiop, will be titled as “price_list.xls.kiop”. Once the encryption is achieved, Kiop puts its own special text document (_readme.txt) into all the folders that store the encrypted files.

The message mentioned by document requesting the random os very comparable to the notifications given by other ransomware threats belonging to the DJVU family. The warning generally indicates that the information has been encrypted and the only solution to get access to it is to use a distinct standalone key. Regretfully, this declaration is definitely true.

The approach to secure the files used by Kiop is not entirely researched. Nevertheless, there is no doubt that each computer system owner might be released a special decryption key, which is definitely unique. It is exceptionally hard to recuperate the data without the suitable type 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 Kiop ransomware 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 criminals who have launched the Kiop virus into the web. In order to acquire the key and restore the important information, the users are told to get in touch with the frauds via email or by telegram and to pay the ransom in the amount of $980.

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

No matter what the amount of the ransom is, we highly encourage that you do not pay the ransom. There is no guarantee that these online scoundrels will keep their promises, so they might not care at all what the victims feel about the encryption, even when the quantity of the ransom is received into their accounts. Thus, paying ransom often does not result in an effective recovery. So, the users might just lose their money for absolutely nothing.

Likewise, we prompt you not to get in touch with the frauds as they instruct. Do not move loan into their wallets. There are no applications that might break the Kiop virus or restore the information for free. For that reason, the only appropriate decision is to bring back the information from possible backups (if readily available).
