I have gotten infected by ransomware on my SBS 2011 server. This server was my Backup Exec Media server. I have been trying to find a way to recover my files from tape backup but am having trouble. None of the online decryptors from Kaspersky or bitdefender etc have worked. Here are the things I know:

 

1. Files are decrypted with a .WALLET file extension. Full extension looks like this: <File>.<Extension>.[ncrypt@cock.li]-id-32E0.wallet

2. I can rename files and delete the extension but still cannot open them.

3. It looks like the file that did the damage was called payday.hta and was placed in the %APPDATA% folder of the infected user account.

4. The ransom note is named ! How Decrypt Files.txt and has very little information:

 

Hello!

All your files have been encrypted

Want resore your files? Write on e-mail - ncrypt@cock.li

 

Please give me any help you can!

 

Thank you.

...1. Files are decrypted with a .WALLET file extension. Full extension looks like this: <File>.<Extension>.[ncrypt@cock.li]-id-32E0.wallet

The .WALLET extension has been used by several ransomwares to include CryptoMix Wallet Ransomware, Dharma (CrySiS) Ransomware, BTCWare .wallet and Sanctions Ransomware which does not contain the standard Dharma/Crysis file markers.

  • .[<email>].ID.<16 random hexadecimal character ID>.WALLET (i.e. [ADMIN@HOIST.DESI].ID[DF1866CB3A6F9701].WALLET) = CryptoMix
  • .id-<8 random hexadecimal characters>.[<email>].wallet (i.e. .id-480EB957.[legionfromheaven@india.com].wallet) = Dharma (CrySiS)
  • .[<email>]-id-[4 random hexadecimal characters>.wallet (i.e. [amagnus@india.com]-id-37DC.wallet) = BTCWare AES-256
    filename.[extension].wallet = Sanctions

Looks like you are dealing with the BTCWare ransomware variant. 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.

The .wallet variant is based on the latest AES-256 version of the BTCWare Ransomware family which uses a different RSA-1024 key and is not decryptable unless you pay the ransom and get the private AES key from the criminals.. There is no way to bruteforce the key for this variant. 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.

Thanks
