From the Publisher
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.
