Before the Internet became widely known as a global tool for terrorists, one perceptive US citizen recognized its ominous potential. Armed with clear evidence of computer espionage, he began a highly personal quest to expose a hidden network of spies that threatened national security. But would the authorities back him up?
Cliff Stoll was an astronomer turned systems manager at Lawrence Berkeley Lab when a seventy-five cent accounting error alerted him to the presence of an unauthorized user on his system. The hacker's code name was "Hunter"-a mysterious invader who managed to break into US computer systems and steal sensitive military and security information. Stoll began a one-man hunt of his own: spying on the spy. It was a dangerous game of deception, broken codes, satellites, and missile bases-a one-man sting operation that finally gained the attention of the CIA . . . and ultimately trapped an international spy ring fueled by cash, cocaine, and the KGB.
