Excerpt

Gragg's script also installed a keylogger, which gave him account and password information to virtually everything the user did from then on, sending it to yet another compromised workstation offshore where Gragg could pick it up at leisure.
What sort of idiot hung the keys to his business out on the street- and more than that, broadcast a declaration from his router telling the world where the keys were? These people shouldn't be left home alone, much less put in charge of peoples' investments. Gragg cleaned up the router's connection log. More than likely the scam wouldn't be detected for months, and even then, the company probably wouldn't tell their clients. They'd just close the barn door long after the Trojan horses were gone. So far, Gragg had a cache of nearly two thousand high-net- worth identities to sell on the global market, and the Brazilians and Filipinos were snapping up everything he offered.

But Decker was in no hurry. He finally placed his hand on a dis-connected rack server sitting on the nearby counter. "They tell me this computer killed two men earlier today." The shock took a while to work through Ross. He had expected some sort of child pornography ring, or a credit card scam.
"Killed? How?"
"I was hoping you could help us explain that."

Larson pointed to a network port in the side of the black box, then traced his finger to a smaller circuit board attached to it. "Check this out: it's a Web server on a chip. It's got a tiny TCP/IP stack. They're used for controlling devices like doors and lights from an IP network. I checked. They've got them all over the building." Larson slid his hand along a CAT5 cable extending from the board into the darkness. "This box is linked to their network, and their network is connected to the Internet. It's conceivable that someone with the right passwords could have activated this switch from anywhere in the world."
"Could the switch be set to activate when a certain person swiped their access card at the security door?"
"Probably. I just don't know enough about these cards yet."
"How long has the switch been here?"
Greer looked at the back of the enclosure. "It was covered in dust when we got to it."
"So that vestibule door has probably been used thousands of times without incident-then suddenly today it kills someone. ."
