MICHAEL CALCE The Hacker

Calce gained notoriety when he was just 15 years old by hacking into some of the largest commercial websites in the world. On Valentine’s Day in 2000, using the hacker alias MafiaBoy, Calce launched a series of denial-of-service attacks across 75 computers in 52 networks, which affected sites such as eBay, Amazon and Yahoo. He was arrested after he was noticed boasting about his hack in online chat rooms. He was received a sentence of eight months of “open custody,” one year of probation, restricted use of the internet, and a small fine.
