Hi

 

One of my clients woke up this morning to a RW attack. 

 

They mainly use a program on the network, so naturally that all became corrupt. 

 

I currently use sync to another server and then MS Backup to do a daily backup on the target machine, I use the "archive" on Sync if anything changes.

 

I restored their program, but there was still a section of files that wasn't being backed up!

 

I think i found the source exe. I assume this as it was the only user that had their dekstop encrypted. TS Server. 

 

I have a file from before and after. I also found the following;

I also found a folder under /users/%%/appdata/roaming/microsoft/crypto/rsa/S-1-5-21-4247503443-1365201607-1068338911-2117/03291a63ac38553c9c9538693b092f45_707ea7b8-f67f-4722-adeb-ddfa91dcab87

I have read your other thread where BTC is not cracked yet, but I thought I would still post as there was a couple of extra bits of information.

Any files that are encrypted with BTCLocker Ransomware will have the .btc extension appended to the end of the encrypted data filename and leave files (ransom notes) named BTC_DECRYPT_FILES.txt, BTC_DECRYPT_FILES.html. More information in this Russian news article: BTCLocker (BTC) Ransomware.

You can submit samples of encrypted files and ransom notes to ID Ransomware for assistance with identification and confirmation. This is a service that helps identify what ransomware may have encrypted your files and then attempts to direct you to an appropriate support topic where you can seek further assistance. Uploading both encrypted files and ransom notes together provides a more positive match and helps to avoid false detections.

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
