The message mentioned by document requesting the random os really similar to the notifications provided by other ransomware hazards belonging to the DJVU family. The warning basically shows that the information has been secured and the only service to get access to it is to use a special standalone key. Regretfully, this statement is definitely true.

It is extremely hard to recuperate the data without the appropriate type in place.
