Fadia was educated at Delhi Public School. He started a website called "HackingTruths", which he claims was judged as the "second best hacking site in the world by the FBI". He claims that when he was 14, he trashed the front page of an Indian magazine's website. He then sent an e-mail to the editor confessing to the hack, suggesting counter measures. At 15, his book on Ethical Hacking made him the youngest author to be published by Macmillan India. More on Ankit Fadia
