Fadia, who became the youngest author published by Macmillan at the age of 14, also runs certificate courses through video conferencing.

However, the 'ethical hacker' has over the time been idolized by geeks but dismissed by critics who have time and again questioned his credibility as an expert. To this, Fadia says his work speaks for himself.

Prod him further about an open letter to him by Forbes India executive editor Charles Assisi earlier this year titled 'Ankit Fadia Revealed' and Fadia says "they got it wrong".

"Charles is senior. Had I been a fake, the students wouldn't have enrolled for my certificate programmes. But, they are as they feel they are getting something good out of it. They got it wrong", he says.

Fadia, also points out that he has been asked to train at various places, including the National police Academy that establish his credentials.
