I've attached the decrypter that I paid for.  It did decrypt some of the files on my C drive, but not all of them.  It also did not touch any of the files that were encrypted on my external drive, despite the program saying all drives have been decrypted.  Can someone help me decrypt all the files seeing as the program shows me the private key that was used to encrypt them?

You can use my BTCWareDecrypter with the key they gave you.

 

https://download.bleepingcomputer.com/demonslay335/BTCWareDecrypter.zip

 

As a warning, the malware has a bug that will 0 out some files instead of actually encrypting them. If a file starts with a bunch of 0 bytes, then it cannot be recovered, because it is destroyed. My decrypter will warn you of files it finds are destroyed.

 

Also be warned if they gave you an incorrect key, or if you were hit by more than the one key, then files will be corrupted. Because of yet another bug in the malware, there's no way to tell if the decryption with a provided key was actually successful, or if it just produced corrupted bytes.

BTCWareDecrypter does not work.  I've used it to try and decrypt a file and it is corrupted.  However the exe file that I've attached does decrypt that file.  Is there anyway that I can instruct the exe file I have to decrypt specific files or directories?

There is an ongoing discussion in this topic where victims can post comments, ask questions and seek further assistance. Other victims have been directed there to share information, experiences and suggestions.Rather than have everyone with individual topics, it would be best (and more manageable for staff) if you posted any more questions, comments or requests for assistance in the above support topic discussion. Demonslay335 can continue to assist you form that topic if there is anything else he can do.

To avoid unnecessary confusion, this topic is closed.

Thanks
