About the book

Cliff Stoll, an astronomer managing computers at Lawrence Berkeley National Laboratory, tells in the first person how a 75-cent accounting error led him to an intruder in the lab's system. The hacker had gained superuser access through a flaw in the movemail function of GNU Emacs. To watch him, Stoll wired borrowed terminals and teleprinters to the lab's incoming phone lines, kept a daily logbook and followed the trail through Tymnet, a defense contractor in Virginia and finally West Germany. He set a trap with a fake SDI department full of invented files, while dealing with the FBI, CIA, NSA and Air Force investigators. Stoll's title carried the cuckoo's egg metaphor from birds over to malware.

James Stanley, founder of SMS Privacy, believes it is the first documented case of a remote attacker misusing a computer, and he singled out how Stoll connected teleprinters to the phone lines to watch the intruder and trace him across several countries.

James Stanley (Founder/SMS Privacy)

"The Cuckoo's Egg" by Clifford Stoll is another great book. I believe it's the first documented account of a computer being misused by a remote attacker. It talks about how Clifford attached physical teleprinters to the incoming phone lines so that he could see what the attacker was actually doing on the computer, and how he traced the attacker across several countries.
