Indeed a great book.

And (tiny spoiler-alert): a small easter-egg (though not intended as such) for people on HN: the founders of HN/YC show up in the book, admittedly in a very minor capacity.

Btw, I recently discovered that Cliff Stoll is one of the awesome guys who appears on the Numberphile YouTube channel, so if you watch that, know that it's him :)

Second this. Fantastic book about true events. If you like the story, there is also a movie which covers the same events as the book. The movie is called "23" and is available in German and English.

My favorite bit was jangling his keys to induce noise in the line to delay the hacker long enough for a trace.

This. Cliff Stoll is better known for his other book, where he got a bunch of predictions about the internet wrong, but Cuckoo’s Nest is a lot better read. Based on a true story, how a few cent $ difference led him to discover a massive hack going on, and how he was chasing the hacker.

The OG of true crime hacking books.

Yep, this one is a great read!

Fantastic book!

Second this.
