A young attacker I'll call Ivan Peters had a target of retrieving the source code for a new electronic game. He had no trouble getting into the company's wide area network, because a hacker buddy of his had already compromised one of the company's Web servers. After finding an unpatched vulnerability in the Web server software, his buddy had just about fallen out of his chair when he realized the system had been set up as a dual-homed host , which meant he had an entry point into the internal network.
