Unfortunately, newer variants of BTCWare (.blocking, .encrypted, .aleta, .gryphon, .nuclear) are AES-256 versions of the malware which use a different RSA-1024 key and are not decryptable unless you have the private AES key from the criminals...there is no way to bruteforce the key for any version after .onyon. Read Demonslay335's comments in Post #293 and Post #432. If possible, your best option is to restore from backups.

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.
