>The Cuckoo's Egg - Cliff Stoll

This is such a nerd-snipe book, I absolutely loved it. A personal account of one of the first cases of (attempted) military espionage via the internet? A system administrator thwarting intruders with his keys? Government agencies not knowing who's responsible for network-based intruders? Hackers from the Chaos Computer Club spying for the Soviets? Written by the Numberphile guy who's selling all those Acme Klein Bottles? Sign me up.
