10. Kevin Mitnick

At age 13, Mitnick used social engineering and dumpster diving to bypass the punch card system used in the Los Angeles bus system.

Social engineering later became his primary method of obtaining information, including user-names and passwords and modem phone numbers.

Mitnick first gained unauthorized access to a computer network in 1979, at 16, when a friend gave him the phone number for the Ark, the computer system Digital Equipment Corporation (DEC) used for developing their RSTS/E operating system software. He broke into DEC’s computer network and copied their software, a crime he was charged with and convicted of in 1988. He was sentenced to 12 months in prison followed by three years of supervised release. Near the end of his supervised release, Mitnick hacked into Pacific Bell voice mail computers. After a warrant was issued for his arrest, Mitnick fled, becoming a fugitive for two and a half years.

According to the U.S. Department of Justice, Mitnick gained unauthorized access to dozens of computer networks while he was a fugitive. He used cloned cellular phones to hide his location and, among other things, copied valuable proprietary software from some of the country’s largest cellular telephone and computer companies. Mitnick also intercepted and stole computer passwords, altered computer networks, and broke into and read private e-mails.

Since 2000, Mitnick has been a paid security consultant, public speaker and author. He does security consulting for Fortune 500 companies and the FBI, performs penetration testing services for the world’s largest companies and teaches Social Engineering classes to dozens of companies and government agencies.
