Mind Maze Prague: The Hack

Your cyber crime detective unit has been contacted because multiple hospitals were attacked by a malicious hacker group. Based on their message, this was only a small demonstration of how serious they are about their plans! They will attack the country's power grid unless they are paid a ransom. Either the money is paid or the whole country goes back to the middle ages without electricity! This is yet the most serious threat you have ever faced! You have to stop the hackers!
