Mmvb Virus Ransomware

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

Mmvb was developed for the sole function to encrypt all popular file types. Logically, as soon as the encryption is successfully accomplished, the users are unable to get access to them. Mmvb virus includes its own “.mmvb” to all the encrypted data. For example, the file “price_list.xls”, once modified by Mmvb, will be entitled as “price_list.xls.mmvb”. As soon as the encryption is achieved, Mmvb puts its own special text file (_readme.txt) into all the folders that store the encrypted files.

The message stated by _readme.txt asking for the random os very similar to the alerts given by other ransomware threats coming from the DJVU family. The caution generally shows that the files have been encrypted and the only solution to get access to it is to use a special standalone key. Regretfully, this statement is definitely real.

The technique to encrypt the files used by Mmvb is not completely researched. Nevertheless, there is no doubt that each computer system owner might be issued a special decryption key, which is definitely unique. It is incredibly tough to recover the information without the appropriate type in location.

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

One more peculiarity of the Mmvb infection is that the users are unable to get access to the key. The decrypting key is hosted on a special server under the complete control by the scoundrels who have actually launched the Mmvb virus into the world wide web. In order to acquire the key and bring back the essential information, the users are informed to connect with the scams via email or by telegram and to pay the ransom in the quantity of $980.

The message also says that individuals must get in touch with the Mmvb authors within 72 hours upon the minute of the information encryption. The alert indicates that by doing so individuals will get a 50% discount rate, therefore, the ransom quantity 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 warranty that these online criminals will keep their guarantees, so they might not care at all what the victims feel about the encryption, even when the amount of the ransom is received into their accounts. Thus, paying ransom frequently does not result in an effective recovery. So, the users might just lose their money for nothing.

Similarly, we advise you not to get in touch with the scams as they advise. Do not move loan into their wallets. There are no applications that might crack the Mmvb ransomware or restore the information at no cost. Therefore, the only right choice is to bring back the information from possible backups (if readily available).
