Ransomware encrypted files

Hi,

We have come across a machine that obtained a ransomware virus. We removed the virus using malwarebytes and ms security essential however the files .... jpg, doc, excel, pdf,  etc..... are all still encrypted.

We ran kaspersky's decrytpors xtoris, rector and rohnna (pardon the mispelling) still nothing. we also submitted sample files to kaspersky but haven't heard anything back.

Our question - Does anyone have a good solution on how to decrypt our files?

Thanks.

Do you know by chance which version of ransomware you have or which variant?  We will need that if we're going to be able to direct you to the right resources to fix this.

We dont. We have an image of the actual lock page but don't know the variant.

Ewww, these type are really nasty.  

The absolute best article and forum I have found on the subject is located here:
http://www.bleepingcomputer.com/virus-removal/cryptorbit-ransomware-information

I use this one when removing it from client machines.   I was able to use the application in one instance and Volume Shadow Copy method to restore previous versions of the files.  

I hope this helps you out.  These sort of things are quite difficult to handle but with some persistence and a little luck you have a decent chance of getting your data back.

THANK YOU!! the test files look good.  Odd how I looked all through bleeping computer and didn't find the article but viola you did and it's working .... only a gazillion more files to go.

Shadow copy wasn't enabled so it was straight to the decryptor tool.

Glad to help! I have had to use it on about 5 people's computers so I happened to have it in bookmarks.

Have fun!

An FYI update - The Anti - Cryptor tool was able to decrypt the picture (60gb worth) but on the majority it changed the image size to approx 200 x200. The tool was unable to decrypt any of the docs and pdf's.

The user has decided to seek another opinion. It will be interesting to see what the folks at Fry's say considering the boys in blue wouldn't even touch it.

Sio2y, thanks for the update.  I'm following up on old threads to see if there was any headway made.  Hopefully a tech with it in their hands was able to do more for you.  I had one of these come through on Monday that I spent 3 hours on and was able to get about half of the data.  It's sort of hit or miss, honestly.  If the decryption tool wasn't able to retrieve it, it may not leave much hope for those.
