It was the ultimate hack. He was looking at an error coded into the heart of the Internet’s infrastructure. This was not a security hole in Windows or a software bug in a Cisco router. This would allow him to reassign any Web address, reroute anyone’s email, take over banking sites, or simply scramble the entire global system. The question was: Should he try it?

The vulnerability gave him the power to transfer millions out of bank accounts worldwide. He lived in a barren one-bedroom apartment and owned almost nothing.

Or, for the sheer geeky joy of it, he could reroute all of .com into his laptop, the digital equivalent of channeling the Mississippi into a bathtub. It was a moment hackers around the world dream of—a tool that could give them unimaginable power. But maybe it was best simply to close his laptop and forget it. He could pretend he hadn’t just stumbled over a skeleton key to the Net. Life would certainly be less complicated. If he stole money, he’d risk prison. If he told the world, he’d be the messenger of doom, potentially triggering a collapse of Web-based commerce.
