Gregston Chu knows all the tricks of being a hacker, from talking his way into secure buildings to exploiting holes in Internet security or gaps in internal company systems to grab control of computers.
That makes him a highly valued consultant and as such, he's crisscrossed the U.S. and traveled to Europe and Asia to uncover computer system vulnerabilities for Fortune 100 companies and other large corporations.
"It is kind of fun to find things that aren't supposed to be found," said Chu, who performs "extreme hacking" work as a senior manager for Ernst & Young LLP's Advanced Security Center, based in Houston. "We get the thrill that a lot of hackers do, without that going to jail part."
