CryptoSearch is not for identification. It is strictly for post-cleanup once you know what you were hit by.

 

It's Dharma, aka CrySiS, as ID Ransomware identifies. It cannot be decrypted without paying the criminals (not recommended).

No, otherwise it would be considered decryptable. That's the whole point of proper cryptography.

 

The malware generates a cryptographically-strong password (meaning it is impossible to bruteforce) for each victim, and that password is then encrypted by the public RSA key, so it cannot be decrypted.

New Arena Crysis Ransomware Variant Released

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.

Thanks
