Funny you should mention this. I am currently reading a book (actually I think it is #13) my brother wrote called "SyberKombat". The main characters are gaming programmers who are kind of vigilantes. Without going into character details, the main story line in this one is some men who write a Cloud based computer game, SyberKombat, which, when downloaded, installs an invisible DLL code packet that turns the computer into a bot on a big cyber network. When someone plays the game and they want to, for instance, blow up a train, it happens in real life. Very simple description, but hopefully you get the idea. Power plants, defense systems, all vital computerized systems with internet access to the Cloud are vulnerable.
Thing is, it's based on fact. So many computer security networks are so vulnerable to a skilled hacker it's almost scary. This book is pure fiction, but ya never know.
