But whats so ethical’about being a hacker? His eyes light up on hearing the obvious question. “I had coined the term when I was writing my first book.

In 1999 - 2000, when he wrote his first book, the term "ethical hacker" has been in wide-spread use among the security and hacker communites for some time. According to "Ethical hacking" by C.C.

"When I got my first book published at the age of 14, the concept of 'good hacking' in those days did not exist.
