I have two friends who are both computer "wizards". They are always in an ongoing contest of security and hacking one another. One is the boss and the other friend is the employee but they are longtime friends.
Once when the employee was home he hacked the bosses computer at work. Every time the boss touched his keyboard the display screen would flip upside down and the computer would announce the bosses name and say he was an idiot. Since the boss could not stop the computer from doing this then the employee won.
This was only fun, but yes, hackers can find the tiniest security problem and hack you.
