join in. Since the addresses were unpublished, companies often felt this obscurity offered enough protection.

DEFCON produced lists of thousands of computer sites to raid. Force would leave it scanning from a hacked Prime computer, and a day or two later he would have an output file with 6000 addresses on different networks. He perused the list and selected sites which caught his attention.

There were a few well-placed pieces of minimalist furniture: a black enamel metal single bed, a modern black bedside table and a single picture on the wall - a photographic poster of lightning, framed in glass. The largest piece of furniture was a blue-grey desk with a return, upon which sat his computer, a printer and an immaculate pile of print-outs. The bookcase, a tall modern piece matching the rest of the furniture, contained
