Calce will address Canada's IT community at the IT360 conference in Toronto next month, where he is scheduled to present the opening keynote alongside Silverman.

"I've gone to the good side now, but I'm going to talk about my experiences in the dark side, so to speak. It's an in-depth look at a community that not many people were a part of. They know of it, but they didn't really get the chance to be part of that community," said Calce.

The lecture will also address threats from criminal organizations and how serious this has become.

"I'm going to be giving them a look into the underground," said Calce. "When you work on the white hat hacking side of the fence, you don't really get the kind of info leaks you would if you were a black hat hacker, so that's going to be a big turn in this conference."

Calce said it's hard to pinpoint what the typical hacker was like eight years ago because normally they would only talk business and were very discreet about their personal information.
