Book excerpts:

Underground is the compelling true story of the rise of the computer underground and the crimes of an elite group of hackers who took on the forces of the establishment.

Tracing an international ring of computer hackers which spanned three continents and nearly a decade of computer crime, author Suelette Dreyfus weaves a gripping tale against a backdrop of cutting edge technology.

Underground uncovers the previously hidden story behind hackers from 8LGM, The Realm, the publishers of International Subversive and other linked Internet hacking groups. These elite hackers were the cream of the international computer underground and broke into tens of thousands of computers, belonging to some of the world's most prestigious institutions including Citibank, the Pentagon, NATO, the FT 100, NASA, Lockheed-Martin, Deutsche Telekom and Australian Telecom.

Based on more than two years of writing and research drawn from hundreds of exclusive interviews and telephone intercepts and over 30,000 pages of court documents, Underground is the first hacking book published out of Australia and the only one to delve into the mind and world of the international computer hacker. Critically aclaimed, it has been said that Underground is the only book to examine the computer underground with real depth and insight.
