The Cuckoo's Egg

A fascinating true account of how astronomer Cliff Stoll tracked down a hacker in the early days of the internet. What begins as a 75-cent accounting discrepancy leads to an international espionage case, showing how vulnerable our computer systems were (and often still are).\n\nDespite being about events from the 1980s, the book remains relevant as a primer on both network security fundamentals and the persistent challenges of attribution and coordination in addressing cyber threats.
