I think it goes back to my high school days. In computer class, the first assignment was to write a program to print the first 100 Fibonacci numbers. Instead, I wrote a program that would steal passwords of students. My teacher gave me an A.

If you go to a coffee shop or at the airport, and you're using open wireless, I would use a VPN service that you could subscribe for 10 bucks a month. Everything is encrypted in an encryption tunnel, so a hacker cannot tamper with your connection.

Back in my day, I would probe by hand. Now you can get commercial software that does the job for you.

All they need to do is to set up some website somewhere selling some bogus product at twenty percent of the normal market prices and people are going to be tricked into providing their credit card numbers.

Hackers are breaking the systems for profit. Before, it was about intellectual curiosity and pursuit of knowledge and thrill, and now hacking is big business.

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.

Any type of operating system that I wanted to be able to hack, I basically compromised the source code, copied it over to the university because I didn't have enough space on my 200 megabyte hard drive.
