Hacker makes US$100,000 a year as a 'bug bounty hunter’
Jobert Abma's HackerOne hunts software holes and counts the US Department of Defence, Twitter, Yahoo, and Uber among its customers

Jobert Abma, the 25-year-old co-founder of a hot start-up called HackerOne, has been breaking into computers since he was 13.
And he's been been getting into hacking scrapes with his co-founder and best friend Michiel Prins for almost as long.
Growing up in the Netherlands, Abma gave Prins an unusual graduation present: the user name and password to a local TV station that did a regular news broadcast about the school.
The duo then took control of the TV station and ran their own broadcast on live TV instead.
"The TV station was not amused," Abma says.
The teachers blamed Prins, who was a year older than Abma, for the hack, and "he never told them that I was to blame," Abma says. Prins wound up having to do 25 hours of community service washing windows, but "that’s what best friends are for."
The two were so good at hacking that Abma's internet provider noticed. It sent a letter to his parents saying, "We think you have a virus installed on your computer because there's all this weird traffic coming from your systems. My parents were like, 'We don’t have a virus. We have a son,'" Abma recalls.
