Amazon.com description: Product Description: Using the exploits of three international hackers, Cyberpunk provides a fascinating tour of a bizarre subculture populated by outlaws who penetrate even the most sensitive computer networks and wreak havoc on the information they find -- everything from bank accounts to military secrets. In a book filled with as much adventure as any Ludlum novel, the authors show what motivates these young hackers to access systems, how they learn to break in, and how little can be done to stop them.
