THE GREAT HACKER WAR

Kevin Mitnick The most famous, and undoubtedly most gifted hacker in history, made a name for himself in 1981 at the tender age of 17 by getting into a phone exchange, which allowed him to redirect subscriber calls in any way he wanted. In 1983, he achieved his first major coup - and also his first arrest - when he accessed a Pentagon computer. It was his repeated offenses that made him a target of the FBI. He was sentenced to five years in prison in the 1990s, but today he is a security consultant and owns his own company: Mitnick Security.

John Draper known as "Cap'n Crunch", Draper was one of the first hackers in history. This moniker comes from the cereal of the same name, inside of which he once discovered a toy whistle (provided as a gift to entice children to ask parents for the cereal). He discovered that he could use the whistle to hack a telephone line and get free phone calls - all that was necessary was to produce a precise tone in the receiver for the method to work. He was arrested in 1976 and sentenced to two months in prison.
