Mmpa Virus Removal Guide (+Decrypt .mmpa files)

Mmpa Virus – Details

Mmpa is a malicious software working as common ransomware. Michael Gillespie, the well-known malware researcher, very first discovered this new name in the DJVU ransomware family.

Mmpa was created for the sole function to encrypt all popular file types. Logically, as quickly as the encryption is successfully accomplished, the users are unable to get access to them. Mmpa ransomware adds its own “.mmpa” to all the encrypted data. For example, the file “price_list.xls”, when modified by Mmpa, will be titled as “price_list.xls.mmpa”. As soon as the encryption is accomplished, Mmpa puts its own unique text document (_readme.txt) into all the folders that keep the encrypted files.

The message specified by _readme.txt requesting the random os really comparable to the notices offered by other ransomware risks coming from the DJVU family. The caution generally shows that the data has been secured and the only option to get access to it is to use a distinct standalone key. Regretfully, this statement is absolutely true.

The technique to encrypt the files used by Mmpa is not totally looked into. However, there is no doubt that each computer owner may be provided a special decryption key, which is definitely distinct. It is extremely hard to recuperate the information without the appropriate type in location.

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

message from Mmpa virus

One more peculiarity of the Mmpa 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 criminals who have actually launched the Mmpa infection into the world wide web. In order to get the key and restore the important data, the users are told to contact the frauds by means of e-mail or by telegram and to pay the ransom in the quantity of $980.

The message likewise states that individuals ought to call the Mmpa authors within 72 hours upon the minute of the data encryption. The alert shows that by doing so individuals will get a 50% discount rate, for that reason, the ransom amount falls to $490.

No matter what the quantity of the ransom is, we highly recommend 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 file encryption, even when the amount of the ransom is gotten into their accounts. Thus, paying ransom often does not lead to an effective recovery. So, the users might just lose their money for absolutely nothing.

Likewise, we advise you not to contact the frauds as they advise. Do not transfer money into their wallets. There are no applications that could break the Mmpa ransomware or restore the data for free. Therefore, the only proper choice is to bring back the information from possible backups (if available).
