In the 1980’s, Cliff Stoll discovered a $0.75 accounting error on the computer systems he managed at Lawrence Berkeley Laboratory. This small discovery would eventually lead him on the year-long pursuit of a group of five KGB sponsored hackers who managed to access numerous US government and military networks. His story has inspired countless people to pursue the profession of information security.
The Cuckoo’s Egg Decompiled is a free online course designed to provide an introduction to information security, as told through the lens of Cliff Stoll’s “The Cuckoo’s Egg” book.

Why did you create this course?
The Cuckoo’s Egg is an important book in information security and helped shape both the field itself and the public perception of security and privacy. Several of my colleagues got into this field or chose to pursue specific facets of it based on reading the book. Even though it is over thirty years old, many of the concepts still apply. Taking this old story and using it as a backing and introduction to modern concepts was really fun, and I thought it would be a unique way to introduce a variety of concepts to people who are new to the field. I also wanted to provide resources that high school and college teachers could utilize for their course development.
How many people attended the live recordings?
Over the eight week run of the course, just over a thousand people took part in the course with many more accessing the recorded videos.
How can I contact you with questions or feedback?
I’m reachable at email@example.com. If you enjoy the materials or adapt them in some way, I’d love to learn about it!
Do you offer any other courses?
I do occasionally offer free courses from time to time. However, I also run a company called Applied Network Defense where we produce high-quality information security practitioner-focused training. If you like our free stuff like this course, you’ll really love our paid products. You can view the complete course catalog at http://networkdefense.io.

I’d like to extend a special thanks to:
- Cliff Stoll for writing the book.
- Hans “Pengo” Hübner for allowing me to interview him for the final installment of the course
- Everyone who attended the live sessions, especially those of you who were there every week
- All the people who served as a sounding board and provided feedback for the course while I developed it
