I need help. Suddenly, all my files were renamed, they now have the extension ‘.derp’. I also found a file that says that my files were encrypted. Google search does not find any free decryptor. Can you tell me if there is a way to decrypt .derp files?
Files with .derp extension are files encrypted with the latest version of STOP ransomware. What is known at the moment. Derp files can be decrypted, but only if they are encrypted with an offline key. For more details about this, see the link to the article below. Read section ‘New Djvu ransomware’ carefully.
