Some of the addresses had also figured in Chinese espionage campaigns documented by other researchers. They were part of a block of about 2,000 addresses belonging to China Unicom (CHU), one of the country’s largest Internet service providers. Trails of hacks had led Stewart to this cluster of addresses again and again, and he believes they are used by one of China’s top two digital spying teams, which he calls the Beijing Group. This is about as far as Stewart and his fellow detectives usually get—to a place and a probable group, but not to individual hackers. But he got a lucky break over the next few months.

Tawnya Grilth registered a command node using the URL dellpc.us. It was a little too close to the name of Stewart’s employer. So Stewart says he contacted Icann (the Internet Corporation for Assigned Names and Numbers), the organization that oversees Internet addresses and arbitrates disputes over names. Stewart argued that by using the word Dell, the hackers had violated his employer’s trademark. Grilth never responded, and Icann agreed with Stewart and handed over control of the domain. By November 2011 he could see hacked computers phoning home from all over the world—he was watching an active espionage campaign in progress.
