Mitu Virus Removal Guide (+Decrypt .mitu files)

Mitu – General Info

Mitu is a harmful software working as common ransomware. Michael Gillespie, the popular virus researcher, first discovered this new name in the DJVU ransomware family.

Mitu was created for the sole function to encrypt all popular file types. Rationally, as soon as the file encryption is effectively accomplished, the users are unable to get access to them. Mitu ransomware adds its own “.mitu” to all the encrypted data. For instance, the file “price_list.xls”, as soon as modified by Mitu, will be entitled as “price_list.xls.mitu”. Once the encryption is achieved, Mitu puts its own distinct text document (_readme.txt) into all the folders that save the encrypted files.

The message specified by _readme.txt requesting for the random os extremely similar to the notices given by other ransomware risks belonging to the DJVU family. The caution essentially shows that the data has been secured and the only solution to get access to it is to use an unique standalone key. Regretfully, this declaration is definitely real.

The technique to encrypt the files utilized by Mitu is not entirely looked into. However, there is no doubt that each computer owner may be provided an unique decryption key, which is definitely distinct. It is incredibly tough to recover the information without the appropriate key in place.

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

One more peculiarity of the Mitu 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 total control by the scoundrels who have actually launched the Mitu infection into the internet. In order to get the key and bring back the crucial data, the users are told to get in touch with the scams through email or by telegram and to pay the ransom in the quantity of $980.

The message likewise says that the people need to get in touch with the Mitu authors within 72 hours upon the minute of the information file encryption. The alert shows that by doing so individuals will get a 50% discount rate, for that reason, 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 crooks will keep their guarantees, so they may not care at all what the victims feel about the file encryption, even when the quantity of the ransom is gotten into their accounts. Thus, paying ransom typically does not lead to a successful recovery. So, the users might merely lose their money for nothing.

Similarly, we urge you not to get in touch with the frauds as they instruct. Do not move money into their wallets. There are no applications that might crack the Mitu virus or bring back the data for free. For that reason, the only correct choice is to bring back the data from possible backups (if offered).
