I work for a letting agency based in the UK, and Saturday our emails went down. Monday morning, we found in fact our entire internet was down - we'd recently had a new phone system installed whereby the phones now run through the broadband connection. We've had some teething problems so naturally blamed the phone company, but also reported this to our IT team.


Quick insight: we couldn't access Microsoft Outlook emails, our system (Vebra, aka CFP) or any documents. All our documents are stored on an external drive called the Nas Box - this is plugged into the server.


After a day of investigating, our IT team found we had been hacked. The ransom note on the server was as follows:


What happened to your files ?
All of your files were protected by a strong encryption.
There is no way to decrypt your files without the key.
If your files not important for you just reinstall your system.
If your files is important just email us to discuss the price and how to decrypt your files.
You can email us to besthuk@mail.ru ; viper317887@gmail.com ; wearehere@sigaint.org 
Write your Email to ALL email addresses PLS
We accept just BITCOIN if you dont know what it is just google it.
We will give instructions where and how you buy bitcoin in your country.
Price depends on how important your files and network is.it could be 0.5 bitcoin to 100 bitcoin.
You can send us a 1 encrypted file for decryption.
Feel free to email us with your country and computer name and username of the infected system.
I have googled this and the same message, some slightly different, seems to be quite common. Our IT team are checking everything but have said it appears the hackers went onto our server, wiped the NAS Box and have taken over our system. The IT team have accepted negligence in that we pay them £££ to stop this type of thing, yet it's happened and we are 99% certain that we have lost everything.
We use a back up USB to restore all of our information in case of a fire, theft or hack - unfortunately, the IT team haven't picked up that this hasn't been backing up and, despite us religiously doing the ritual to back it up, we have lost everything since June 2016. This is the time we changed from back up tapes to the back up USB as per their recommendations.
Is there ANYTHING that can be done? We face having to log all rents, invoices, statements, fees and charges again since June 2016 which, for an agency our size, is a living nightmare. If anyone could help in absolutely any way, I would be incredibly grateful.
Thanks in advance!

Any files that are encrypted with Surprise Ransomware will have the .surprise or .tzu extension appended to the end of the encrypted data filename and leave files (ransom notes) named DECRYPTION_HOWTO.Notepad and Encrypted_Files.Notepad. The ransom note instructs victims to contact the cyber-criminals at "nowayout@protonmail.com", "nowayout@sigaint.org", "besthuk@mail.ru", "viper317887@gmail.com" or "wearehere@sigaint.org" to get payment instructions.

Unfortunately, there is no known way at this time to decrypt files encrypted by Surprise Ransomware (which is based on EDA2) without paying the ransom.

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.
