Mmpu Virus Removal Guide (+Decrypt .mmpu files)

Mmpu – Ransomware

Mmpu is a harmful software application functioning as typical ransomware. Michael Gillespie, the popular malware researcher, first discovered this new name in the DJVU ransomware family.

Mmpu was developed for the sole purpose to encrypt all popular file types. Logically, as quickly as the encryption is effectively achieved, the users are not able to get access to them. Mmpu ransomware includes its own “.mmpu” to all the encrypted files. For example, the file “price_list.xls”, once crypted by Mmpu, will be titled as “price_list.xls.mmpu”. As soon as the file encryption is accomplished, Mmpu puts its own distinct text file (_readme.txt) into all the folders that save the encrypted files.

The message mentioned by text file asking for the random os really similar to the notices provided by other ransomware threats belonging to the DJVU family. The caution generally shows that the data has been secured and the only service to get access to it is to use a distinct standalone key. Regretfully, this declaration is absolutely true.

The technique to encrypt the files used by Mmpu is not entirely looked into. However, there is no doubt that each computer owner may be provided a special decryption key, which is absolutely distinct. It is incredibly difficult to recover the data without the appropriate type in location.

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

One more peculiarity of the Mmpu infection is that the users are unable to get access to the key. The decrypting key is hosted on an unique server under the complete control by the crooks who have launched the Mmpu virus into the world wide web. In order to acquire the key and bring back the important information, the users are told to contact the frauds through e-mail or by telegram and to pay the ransom in the amount of $980.

The message also states that the people must get in touch with the Mmpu authors within 72 hours upon the minute of the data encryption. The alert shows that by doing so the people will obtain a 50% discount, therefore, the ransom quantity drops down to $490.

No matter what the quantity of the ransom is, we highly encourage that you do not pay the ransom. There is no assurance that these online criminals will keep their guarantees, so they may not care at all what the victims feel about the file encryption, even when the amount of the ransom is received into their accounts. Hence, paying ransom often does not result in an effective healing. So, the users might merely lose their money for nothing.

Likewise, we advise you not to call the scams as they instruct. Do not move loan into their wallets. There are no applications that might break the Mmpu virus or bring back the data at no charge. Therefore, the only proper choice is to restore the data from possible backups (if offered).
