<div class='title'>1. THE FOLLOWING IS STRICTLY FORBIDDEN</div>
<div class='title.sub'> 1.1 EDITING FILES ON HDD.</div>
<ul>Renaming, copying or moving any files could DAMAGE the cipher and decryption will be impossible.</ul>
<div class='title.sub'> 1.2 USING THIRD-PARTY SOFTWARE.</div>
<ul>Trying to recover with any software can also break the cipher and file recovery will become a problem.</ul>

<div class='title.sub'> 2.1 HOW DID THIS HAPPEN</div>
<ul>The security of your IT perimeter has been compromised (it's not perfect at all).
We encrypted your workstations and servers to make the fact of the intrusion visible and to prevent you from hiding critical data leaks.
We spent a lot of time researching and finding out the most important directories of your business, your weak points.
We have already downloaded a huge amount of critical data and analyzed it. Now its fate is up to you, it will either be deleted or sold, or shared with the media.</ul>
