At first I thought you were indicating, that Dom was behind the Trinity Hack which happened some months ago 
He was never hiding his hacker background and even talked a bit about it in a big german TV show: https://www.youtube.com/watch?v=aeHWXXWa--o
There are no english subtitles, but he basically says, that he - maybe among other things - hacked Call of Duty to become the #1 player in this game. He also sold these "opportunities" (as he calls it) to other players then. It's not a crime or illegal according to his point of view.
After starting IOTA, Dominik Schiener described his hacking experience:

"I started hacking computer games when I was 14 and then sold these modifications and earned a fair amount of income for my age and effort. With the money, I then tried to build an advertising platform"
