University at Buffalo School of Management studied personality traits of college students in computer science and management to see which personality traits led to three different kinds of computer hacking: white hat, gray hat and black hat. White hatters are ethical hackers, gray hats are the "hacktivists," black haters are thrill-seeking and white hatters tend to be narcissists. Gray hatters oppose authority, black hatters seek thrill-seekers, and narcissism. Black haters may just be in it for the thrill of the attack, revenge or notoriety, researchers say.
