What happend?
----------------------------------------------
Your computers and servers are encrypted, backups are deleted from your network and copied. We use strong encryption algorithms, so you cannot decrypt your data.
But you can restore everything by purchasing a special program from us - a universal decoder. This program will restore your entire network.
Follow our instructions below and you will recover all your data.
If you continue to ignore this for a long time, we will start reporting the hack to mainstream media and posting your data to the dark web.
What guarantees?
----------------------------------------------
We value our reputation. If we do not do our work and liabilities, nobody will pay us. This is not in our interests.
All our decryption software is perfectly tested and will decrypt your data. We will also provide support in case of problems.
We guarantee to decrypt one file for free. Go to the site and contact us.
