A white hat is a hacker with heart, Wiki gives a conservative definition here but a description with firework flair was recently documented in a Bloomberg piece quoting self-aggrandising hacker, Tillie Kottmann, “lots of curiosity, fighting for freedom of information and against intellectual property, a huge dose of anti-capitalism, a hint of anarchism — and it’s also just too much fun not to do it.” That really turns the hacker ‘stealing data and cash’ trope on its head.
