The warning generally indicates that the data has been secured and the only service to get access to it is to use a special standalone key. Regretfully, this statement is absolutely real.
The technique to encrypt the files used by Coty is not totally looked into. Nevertheless, there is no doubt that each computer system owner may be provided a special decryption key, which is definitely distinct. It is exceptionally tough to recover the information without the proper type in location.
“Don’t worry, you can return all your files!”, from _readme.txt message:
One more peculiarity of the Coty infection is that the users are unable to get access to the key.
