This name and image had been chosen for their similarity to actual Internet companies and their logos. For the last two years, Akamai Tree's network of servers actually consisted of carefully designed traps. They incorporated multilevel quad-check honeynets established in both business and academic domains. This enabled them to track backward from servers to user with an 87 percent success rate. They had baited the net starting last year, first with ordinary feed and then with increasingly juicy morsels.

"Our sites mirrored established geology, applied physics, ecology, civil engineering, and biogeography sites," Hitomi said. "To attract deep divers, typical data included information on the use of explosives in seismic recordings, the tests of the stability of structures to vibration and earthquake damage, and in our oceanographic sites, data on hurricanes, rogue waves, tsunamis, and so forth. All this is familiar to you."

Kenner nodded.

Hitomi continued: "We knew we had a disseminated enemy, and a clever one. Users often operate behind netnanny firewalls, or used AOL accounts with teen ratings, to imply they are juvenile pranksters or kiddie scripters. But they are nothing of the sort. They are well organized, patient, and unrelenting. In recent weeks, we have begun to understand more."

The screen changed, showing a list.

"Out of a mix of sites and discussion groups, our sys progs found the deep divers clustered on the following category topics:

Aarhus, Denmark

Argon/Oxygen Drives

Australian Military History

Caisson Seawalls

Cavitation (Solid)

Cellular Encryption

Controlled Demolition

Flood Mitigation

High-Voltage Insulators

Hilo, Hawaii

Mid-Ocean Relay Network (MORN)
