If your computer is a fortress, hackers are the interlopers with pointy metal hats who charge the gate, scale the walls, or use stolen keys to get inside. Their mission? To steal your crown jewels or carve graffiti on the walls, such as “The king is a weenie.” In this sample chapter Andy Walker tells you why they want access to your computer, how they try to gain access to it, and what you stand to lose if they do. There’s also a really exciting section on how to stop them and what to do if one of them succeeds. It’s like a medieval video game, but scarily, it’s real.
