Mkos Virus Removal Guide (+Decrypt .mkos files)

Mkos – Ransomware

Mkos is a destructive software application functioning as common ransomware. Michael Gillespie, the well-known virus researcher, first found this new name in the DJVU ransomware family.

Mkos was created for the sole purpose to encrypt all popular file types. Logically, as quickly as the encryption is successfully achieved, the users are not able to get access to them. Mkos ransomware includes its own “.mkos” to all the encrypted data. For example, the file “price_list.xls”, when crypted by Mkos, will be titled as “price_list.xls.mkos”. When the encryption is achieved, Mkos puts its own unique text file (_readme.txt) into all the folders that keep the encrypted files.

The alert specified by _readme.txt requesting the random os extremely similar to the alerts offered by other ransomware risks coming from the DJVU family. The warning essentially shows that the data has been secured and the only option to get access to it is to use an unique standalone key. Regretfully, this declaration is absolutely real.

The method to encrypt the files used by Mkos is not totally looked into. However, there is no doubt that each computer owner might be issued an unique decryption key, which is definitely special. It is extremely hard to recover the information without the proper key in location.

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

One more peculiarity of the Mkos virus is that the users are unable to get access to the key. The decrypting key is hosted on a special server under the total control by the criminals who have actually introduced the Mkos ransomware into the internet. In order to obtain the key and bring back 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 likewise states that individuals need to get in touch with the Mkos authors within 72 hours upon the moment of the data encryption. The alert suggests that by doing so the people will get a 50% discount rate, therefore, the ransom amount drops down to $490.

No matter what the quantity of the ransom is, we highly advise that you do not pay the ransom. There is no warranty that these online crooks will keep their promises, so they may not care at all what the victims feel about the file encryption, even when the amount of the ransom is gotten into their accounts. Hence, paying ransom frequently does not result in an effective recovery. So, the users may merely lose their money for nothing.

Likewise, we urge you not to contact the frauds as they advise. Do not move cash into their wallets. There are no applications that could crack the Mkos ransomware or bring back the data at no charge. Therefore, the only right choice is to restore the information from possible backups (if offered).
