I get hired to hack into computers now and sometimes it's actually easier than it was years ago.

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.

It doesn't work the same way everywhere. The Americans are the most gullible, because they don't like to deny co-workers' requests. People in the former Soviet bloc countries are less trusting, perhaps because of their previous experiences with their countries' secret services.

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.

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