------Dear managers!------
If you are reading this, it means your network has been attacked. What does that mean?
We hacked your network and now all your files, documents NDA, clients databases, projects and other important data are safely encrypted with reliable algorithms.
We also have a copy of all your data.
WARNING!!! You don't have to go to the POLICE, etc. Otherwise we will not be able to help you.
----------------------------------------------------------------------------------------------------------
You cannot access the files right now. But do not worry. You can get it back! It is easy to recover in a few steps.
As proof, we can decrypt any 3 files you provide.
Files must not be larger than 1 megabyte and must not contain data tables.
We are also ready to provide proof of the leak after you confirm that you are a legitimate representative of the company.
We are not interested to ruin your business. We want to get ransom and be happy.
Please bring this information to your team leaders as soon as possible.
Contacting us will be the fastest and safest solution to the problem. In case of a successful transaction, we will restore your systems within 4-6 hours, as well as give recommendations on how to ensure security.
If you don't contact us within 48 hours, we will start publishing your data in the public domain and on our blog.
