I characterize myself as a retired hacker. I'm applying what I know to improve security at companies.

When an attacker fails with one person, they often go to another person. The key is to report the attack to other departments. Workers should know to act like they are going along with what the hacker wants and take copious notes so the company will know what the hacker is trying to find.

I obtained confidential information in the same way government employees did, and I did it all without even touching a computer. ... I was so successful with this line of attack that I rarely had to go towards a technical attack.

I get hired by companies to hack into their systems and break into their physical facilities to find security holes. Our success rate is 100%; we've always found a hole.

Social engineers veil themselves in a cloak of believability.

I could have evaded the FBI a lot longer if I had been able to control my passion for hacking.

I saw myself as an electronic joy rider.
