I use Spam Arrest because of the amount of junk mail I get. Any legitimate person who wants to send me a message has to jump through hoops before they can be added to my opt-in list.

I don't want to jump through hoops for people.

I'm still a hacker. I get paid for it now. I never received any monetary gain from the hacking I did before. The main difference in what I do now compared to what I did then is that I now do it with authorization.

We have to send the message that this is wrong.

It's kind of interesting, because hacking is a skill that could be used for criminal purposes or legitimate purposes, and so even though in the past I was hacking for the curiosity, and the thrill, to get a bite of the forbidden fruit of knowledge, I'm now working in the security field as a public speaker.

Most of the computer compromises that we hear about use a technique called spear phishing, which allows an attacker access to a key person's workstation. It's extremely difficult to defend against.
