Other times, hacking is harsh and done with the wicked goal to hurt people through identity theft or other harm. You are likely familiar with the stereotypical 1980's hacker: the evil criminal who is socially isolated. While this stereotype does indeed describe some modern 'black hat' hackers, there exists a subset of hackers who are not criminals. In fact, there are many hackers who use their knowledge for good.
