Are you sure that you correctly recorded the name of the file with an extension from Ransomware?


Maybe it's written like this?

.java is one of the newer variants of Dharma (CrySiS) Ransomware...it uses an id-<8 random hexadecimal characters>.[<email>] followed by the extension appended to the end of the encrypted data filename.

You can submit (upload) samples of encrypted files, ransom notes and any contact email addresses or hyperlinks provided by the cyber-criminals to
ID Ransomware for assistance with identification and confirmation.

Unfortunately, there is no known method to decrypt files encrypted by the .java variant without paying the ransom and obtaining the private RSA keys from the criminals. If possible, your best option is to restore from backups, try file recovery software or backup/save your encrypted data as is and wait for a possible solution at a later time.

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...it includes experiences by experts, a variety of IT consultants, end users and company reps who have been affected by ransomware infections. To avoid unnecessary confusion, this topic is closed.
