Garbage can provide important details for hackers: names, telephone numbers, a company's internal jargon.

It's true, I had hacked into a lot of companies, and took copies of the source code to analyze it for security bugs. If I could locate security bugs, I could become better at hacking into their systems. It was all towards becoming a better hacker.

I was addicted to hacking, more for the intellectual challenge, the curiosity, the seduction of adventure; not for stealing, or causing damage or writing computer viruses.

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.

My actions constituted pure hacking that resulted in relatively trivial expenses for the companies involved, despite the government's false claims.

I did get a huge endorphin rush when I was able to crack a system because it was like a video game.

The perfect PIN is not four digits and not associated with your life, like an old telephone number. It's something easy for you to remember and hard for other people to guess.
