Max Butler

Max Butler is a former FBI informant who operated a stolen credit-card site called CardersMarket. Known online as "Iceman," he assembled one of the Internet's largest cybercrime commerce sites, with thousands of users, and ran it out of his San Francisco apartments.

A series of blunders by associates -- getting caught using stolen cards in retail stores -- led to the site's unraveling and Butler's arrest and incarceration. He was sentenced to 13 years in prison for stealing 2 million credit-card numbers, which were used to rack up $86 million in fraudulent charges.
