9. Adrian Lamo
Lamo gained media attention when he hacked Microsoft, Yahoo! and Google. Since that obviously wasn’t enough for this guy, he decided to hack The New York Times. He breached into the company’s network and gained access to subscribers’ personal info as well as all the company’s top executives. However, he is better known for tipping Chelsea Manning, the person who leaked thousands of government’s classified documents and was sentenced to 35 years in prison for his actions.
