The e-mail message addressed to a Booz Allen Hamilton executive was mundane—a shopping list sent over by the Pentagon of weaponry India wanted to buy. But the missive turned out to be a brilliant fake. Lurking beneath the description of aircraft, engines, and radar equipment was an insidious piece of computer code known as "Poison Ivy" designed to suck sensitive data out of the $4 billion consulting firm's computer network.
The Pentagon hadn't sent the e-mail at all. Its origin is unknown, but the message traveled through Korea on its way to Booz Allen. Its authors knew enough about the "sender" and "recipient" to craft a message unlikely to arouse suspicion. Had the Booz Allen executive clicked on the attachment, his every keystroke would have been reported back to a mysterious master at the Internet address cybersyndrome.3322.org, which is registered through an obscure company headquartered on the banks of China's Yangtze River.
