Once the encryption is accomplished, Essy puts its own special text document (_readme.txt) into all the folders that save the encrypted files.
The alert specified by _readme.txt requesting for the random os extremely comparable to the notifications given by other ransomware hazards coming from the DJVU family. The warning basically indicates 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 absolutely true.
The approach to secure the files utilized by Essy is not totally investigated. However, there is no doubt that each computer system owner might be issued an unique decryption key, which is definitely unique. It is exceptionally tough to recuperate the data without the suitable type in location.
