DeadBolt decryptor

DeadBolt encrypts QNAP devices using AES-128, and appends the extension ".deadbolt".

This decryptor requires a key received after paying the criminals.

An example of the ransom note "!!!_IMPORTANT_README_WHERE_ARE_MYFILES!!!.txt" can be found below:


===============================================================================
              /!\ ALL YOUR FILES HAVE BEEN LOCKED BY DEADBOLT /!\              
===============================================================================

# What happened?

All your files have been encrypted and made inaccessible. This includes 
(but is not limited to) Photos, Documents and Spreadsheets.

# Why Me?

This is not a personal attack. You have been targeted because of the inadequate 
security provided by your vendor (QNAP).

# What now?

Visit your QNAP machine in a webbrowser and follow the instructions to
get your files back.

# Important Message for QNAP
