The infamous 15-year-old hacker who successfully launched a series of denial-of-service attacks in early 2000 that brought down Yahoo, Amazon, eBay and CNN, among others, is coming to Toronto next month.

The attacks, which took the FBI and RCMP two months to trace back to the Montreal high school student, led Michael "Mafiaboy" Calce to plead guilty to 55 counts of mischief, serve eight months juvenile detention and remain silent for eight years.

Calce, now a 23-year-old security consultant, agreed to his first media interview last fall. This coincided with the release of his book, Mafiaboy: How I Cracked the Internet and Why It's Still Broken, which Calce co-authored with journalist Craig Silverman.

Currently in the process of incorporating a pen testing company, Calce plans to share his past experiences and knowledge of hacker practices with the IT and business communities through lectures and seminars at upcoming conferences.

"Hopefully my experience will educate the business and IT world. I'm hoping to better the community and industry," he said.
