A true-life account of computer espionage tells of a year-long single-handed hunt for a computer thief known as "Hunter," a hacker who stole sensitive security and military information from American computer files to sell to Soviet intelligence agents. Reprint.

Cliff Stoll was an astronomer turned systems manager at Lawrence Berkeley Lab when a 75-cent accounting error alerted him to the presence of an unauthorized user on his system. The hacker's code name was Hunter -- a mystery invader hiding inside a twisting electronic labyrinth, breaking into U.S. computer systems and stealing sensitive military and security information. Stoll began a one-man hunt of his own, spying on the spy -- and plunged into an incredible international probe that finally gained the attention of top U.S. counterintelligence agents. The Cuckoo's Egg is his wild and suspenseful true story -- a year of deception, broken codes, satellites, missile bases, and the ultimate sting operation -- and how one ingenious American trapped a spy ring paid in cash and cocaine, and reporting to the KGB.

Cosmopolitan Nothing short of fascinating...Even if you don't know a byte from a bagel, The Cuckoo's Egg will grip you on page one and hold you as ferociously as the best mystery...It's the intensely human, often funny voice of the man on the trail that makes this book so wonderful.
