--------------- Hello ---------------
*** By BABUCK LOCKER ***
Your computers and servers are encrypted, and backups are deleted.
We use strong encryption algorithms, so no one has yet been able to decrypt their files without our participation.
The only way to decrypt your files is to purchase a universal decoder from us, which will restore all the encrypted data and your network.
Follow our instructions below, and you will recover all your data:
1) Pay 0,006 bitcoin to 1E6cvG6iEbufvYspsDa3XQ3WJgEMvRTm9i
2) Send us message with transaction id to babuckransom@tutanota.com
3) Launch decryptor.exe, which our support will send you through email
What guarantees?
-----------------------------------------------------
We value our reputation. If we will not do our work and liabilities, nobody will pay us. This is not in our interests.
All our decryption software is tested by time and will decrypt all your data.
-----------------------------------------------------
!!! DO NOT TRY TO RECOVER ANY FILES YOURSELF. WE WILL NOT BE ABLE TO RESTORE THEM!!!
