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

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.

We have problems with our physical security, operational security through to management.

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

Some people think technology has the answers.

Computer hacking really results in financial losses and hassles. The objectives of terrorist groups are more serious. That is not to say that cyber groups can't access a telephone switch in Manhattan on a day like 9/11, shut it down, and therefore cause more casualties.

My argument is not that I shouldn't have been punished, but that the punishment didn't fit the crime.
