   -> This is the extension added by the ransomware to the files.

   -> This is the list of extensions that will be encrypted by the ransomware. Beware to keep the order.
- ransomware-excluded-extensions",
    -> This is the list of extensions that will not be encrypted by the ransomware. Beware to keep the order.
