Dear all,
 
I am looking for your assistance on Trojan .[amagnus@india.com].wallet attacked my server on only one folder where all files in that folder changed their extensions to .[amagnus@india.com].wallet.
We need a quick analysis and because that server is used a lot by all staff to share data and it hosts DHCP.
Measures taken:
I disconnected the server immediately and try to backup other files to a separate hard disk.
 
On my side, I am trying to see what to do to recover my files and protect the server.
 
now I need you support.
 
Thank you
 
Nazario

There are several different variants of Dharma Ransomware with different file extensions appended to the end of encrypted filenames.

Any files that are encrypted with Dharma Ransomware (a new variant of CrySiS) will have an .[<email>].dharma, .[<email>].wallet or .<email>.zzzzz extension appended to the end of the encrypted data filename (i.e. [worm01@india.com].dharma, [bitcoin143@india.com].wallet, [amagnus@india.com].zzzzz) and leave files (ransom notes) named README.txt, README.jpg.

Unfortunately, there is no known way at this time to decrypt files encrypted by Dharma variants without paying the ransom. Our crypto malware experts who analyze these infections suspect another cyber criminal forked the code and generated their own keys which were not part of the leaked master decryption keys for the original CrySiS variants.

There is an ongoing discussion in this topic where you 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
