Quoted from the page.
Unfortunately, it is not currently possible to decrypt the files encrypted by the STOP/DJVU ransomware. It may, though, be possible in the future if the decryption keys are recovered from the cybercriminals’ servers. Therefore, if you do not plan on paying the ransom, it is advised that you make an image of the encrypted drives so that you can possibly decrypt them in the future.
