The Cuckoo’s Egg

In this book, Clifford Stoll recounts his unexpected adventure as a computer systems manager at the Lawrence Berkeley National Laboratory.

A 75-cent accounting error leads him to discover an unauthorized user on the system, later identified as a hacker named 'Hunter' who was stealing sensitive military information.

Stoll's one-man investigation involves a high-stakes game of deception, broken codes, satellites, and missile bases, eventually gaining the attention of the CIA. The book details the early days of cybersecurity, the challenges of persuading government agencies to cooperate, and the race against time to safeguard sensitive information from falling into the wrong hands.
