...hackers he was stalking, part of a cyberespionage ring that federal investigators code-named Titan Rain, first caught Carpenter's eye a year earlier when he helped investigate a network break-in at Lockheed Martin in September 2003. A strikingly similar attack hit Sandia several months later, but it wasn't until Carpenter compared notes with a counterpart in Army cyberintelligence that he suspected the scope of the threat. Methodical and voracious, these hackers wanted all the files they could find, and they were getting them by penetrating secure computer networks at the country's most sensitive military bases, defense...
...sending them to mainland China. They always made a silent escape, wiping their electronic fingerprints clean and leaving behind an almost undetectable beacon allowing them to re-enter the machine at will. An entire attack took 10 to 30 minutes. "Most hackers, if they actually get into a government network, get excited and make mistakes," says Carpenter. "Not these guys. They never hit a wrong...
...chasing the spies as they hijacked a web of far-flung computers. Eventually he followed the trail to its apparent end, in the southern Chinese province of Guangdong. He found that the attacks emanated from just three Chinese routers that acted as the first connection point from a local network to the Internet...
...security are disturbing. In recent years, the counterintelligence community has grown increasingly anxious that Chinese spies are poking into all sorts of American technology to compete with the U.S. But tracking virtual enemies presents a different kind of challenge to U.S. spy hunters. Foreign hackers invade a secure network with a flick of a wrist, but if the feds want to track them back and shut them down, they have to go through a cumbersome authorization process that can be as tough as sending covert agents into foreign lands. Adding in extreme sensitivity to anything involving possible Chinese espionage--remember...
...cyberspying metastasizes, frustrated network protectors say that the FBI in particular doesn't have enough top-notch computer gumshoes to track down the foreign rings and that their hands are often tied by the strict rules of engagement. That's where independents--some call them vigilantes--like Carpenter come in. After he made his first discoveries about Titan Rain in March 2004, he began taking the information to unofficial contacts he had in Army intelligence. Federal rules prohibit military-intelligence officers from working with U.S. civilians, however, and by October, the Army passed Carpenter and his late-night operation...
