years ago and just found here: https://bookriot.com/books-about-hackers/. This is a fantastic book, he was just so clever figuring out what was going on, and I still think about it sometimes. Check it out.
“The Cuckoo’s Egg: Tracking A Spy Through The Maze Of Computer Espionage by Cliff Stoll
This book is a bona fide classic that kicked off the sub-genre of books about hackers. It follows Stoll as he realizes the threat presented by a rogue coder named Hunter, figures out how to track him, and gets down to stopping the bad guy.”
