NPPP Ransomware infected

Recommended Posts

Hello @tri bagus

Thank you for contacting Emsisoft Support.

NPPP is a newer variant of the STOP/DJVU family of ransomware and is not supported by our decryption tool.  Despite that, I would like for you to run the STOP/DJVU decryption tool anyway.  That will accomplish a couple of things.  First, it will deactivate and remove any malware that was installed by the ransomware.  This will prevent new files from being encrypted and will prevent re-encryption if files are restored from a backup.  Second, the decryption tool will determine the ID of the encrypted files.  Any ID ending in t1 is an Offline ID anything else is an Online ID.  This is important as it tells us how the encryption key was generated.  There may be multiple Ids, especially if communication between the target system and the command & control server is interrupted for any reason, or because the file encryption was done in stages to avoid detection.  An Offline ID means that the encryption key pair was generated locally and the encryption key is encoded in a file.  An Online ID means the encryption key pair was generated and stored on a remote command & control server under the control of the ransomware gang responsible for encrypting your files.

Why is this important?  The ID of the file(s) is how private encryption keys are identified.  If we have a private encryption key matching the ID for a file(s) then that can be used to decrypt the file(s).  However, this is all contingent on us having a matching private encryption key in our database.  The downside of all this is that we are not currently in possession of private encryption keys for the NPPP variant of STOP/DJVU.

General Notes With Regards to STOP/DJVU

 

  1. Why won't the decrypter run? The decrypter requires version 4.5.2 or newer of the Microsoft .NET Framework, so this could mean your version of the .NET Framework is out of date. We recommend installing the latest version of the .NET Framework (4.8 at the time of writing this), and then trying the decrypter again.
  2. What does "Remote name could not be resolved" mean?  It's an indication of a DNS issue. Our first recommendation is to reset your HOSTS file back to default. Microsoft has an article about this at the following link:https://support.microsoft.com/en-us/help/972034/how-to-reset-the-hosts-file-back-to-the-default
  3. If the decryption tool tells you the files cannot be decrypted, then they cannot be decrypted.  That is not an error message.
  4. If your files have an Online ID that means that the file(s) encryption keys were generated and stored on a command & control server under the control of the ransomware gang responsible for encrypting your files.  We do not have access to those keys.
  5. If your files have an Offline ID and were not decrypted it is because we do not have the corresponding decryption key in our database.  Do not ask us when we plan on adding it, because we do not have it or a way for generating your decryption key.
  6. Our database does include some Offline ID decryption keys for newer variants of the STOP/DJVU family of ransomware.  If the files were encrypted with an Offline ID that matches one of the decryption keys in our database, then our decryption tool will be able to decrypt those files that were encrypted using that key.
  7. New Variant STOP/DJVU utilizes both the RSA and Salsa20 encryption algorithms.  Both RSA and Salsa20 are considered secure encryption methods and are unbreakable using current technologies. They are not reversible, cannot be cracked, and we are not able to generate a decryption key.  So do not send us encrypted files thinking we can recover your decryption key, we can't.

This is a newer variant of STOP/Djvu. If you have an offline ID, then once we can find the decryption key for this variant and add it to our database you should be able to recover your files. However, if you have an online ID (which is more likely) then it will not be possible to recover your files. There is more information at the following link:
