Carl Bialik from WSJ writes "The Wall Street Journal profiles Neil Barrett, 'a former computer hacker who once infiltrated the system controlling a telescope at a Hawaii laboratory' and is now an expert witness causing problems for Microsoft in its antitrust battle with the European Union. Barrett 'has helped put the British glam rocker Gary Glitter behind bars for pedophilia. And he also has helped prosecute a teenage hacker from Wales, who claimed to have stolen Bill Gates' credit-card number and sent the Microsoft founder a shipment of Viagra. [...] In the corporate world, Mr. Barrett once met a challenge to hack into a large multinational company's system in four days to win a security assignment. He stole the company's undisclosed new logo as a trophy, he wrote.'"
