Tom Anderson, cofounder of MySpace and everyone's first friend when a MySpace account is initially created, was a hacker in the 80's and broke into Chase Manhattan Bank's system. His group's activity eventually prompted one of CA's largest FBI raids ever. Interesting reading :-)

Anderson, using the name Lord Flathead, was a computer hacker at least since he was 13 years old, which is just about the time the movie WarGames came out in theaters. Like David Lightman in WarGames (played by Mathew Broderick), Anderson was able to hack into computer systems by simply figuring out the right phone number (this was called "war dialing" and was done with the help of a simple computer program that dialed sequential phone numbers until it received a modem response, signaling a computer system on the other end, usually a UNIX mainframe that often had a default password or no password at all). Once you were past the password security, you often had deep access to whatever system you had called.

According to a New York Times article in October 1985, "Lord Flathead," was the leader of an early black-hat hacker group when he was 14 years old. In July and August 1985, between his freshman and sophomore years, Anderson hacked into a Chase Manhattan Bank DEC VAX computer system (like the one in the image below) that handled "much of Chase's data processing and record keeping, including records of home mortgages and...portfolios of major customers such as pension funds." He subsequently showed up to 40 of his friends how to do it.
