Mmuz was developed for the sole purpose to encrypt all popular file types. Realistically, as quickly as the file encryption is effectively achieved, the users are unable to get access to them. Mmuz virus adds its own “.mmuz” to all the encrypted files. For instance, the file “price_list.xls”, once modified by Mmuz, will be entitled as “price_list.xls.mmuz”. When the file encryption is accomplished, Mmuz puts its own unique text document (_readme.txt) into all the folders that keep the encrypted files.
The message stated by text file requesting the random os really similar to the notifications given by other ransomware risks coming from the DJVU family. The caution generally shows that the information has been encrypted and the only service to get access to it is to use an unique standalone key. Regretfully, this declaration is definitely real.
The approach to secure the files used by Mmuz is not entirely investigated. However, there is no doubt that each computer system owner may be released an unique decryption key, which is absolutely distinct. It is exceptionally hard to recover the information without the appropriate type in location.
