Mbtf was developed for the sole function to encrypt all popular file types. Realistically, as quickly as the file encryption is effectively accomplished, the users are unable to get access to them. Mbtf virus adds its own “.mbtf” to all the encrypted data. For example, the file “price_list.xls”, as soon as modified by Mbtf, will be entitled as “price_list.xls.mbtf”. As soon as the encryption is achieved, Mbtf puts its own unique text document (_readme.txt) into all the folders that keep the encrypted files.
The message specified by _readme.txt requesting for the random os really comparable to the notices given by other ransomware threats coming from the DJVU family. The warning essentially indicates that the files have been encrypted and the only solution to get access to it is to use an unique standalone key. Regretfully, this statement is absolutely true.
The method to encrypt the files utilized by Mbtf is not completely looked into. However, there is no doubt that each computer owner may be provided an unique decryption key, which is definitely distinct. It is extremely tough to recuperate the information without the proper type in place.
