One of my clients was hit by this newest variant of the CrYsis encryption attack.
I have tried using several older tools but so far nothing has succeeded. And this attack deleted shadow copies from my drives as well.
Does anyone have any guidance on newer decryption tools that might work?
This is the naming convention added to the encrypted files: ".id-########.[email@example.com].arena"

"All your files have been encrypted!

Write this ID in the title of your message ########
