Nightmare is an introductory course on binary exploitation and reverse engineering built around CTF challenges. Its materials are structured linearly and include documented write-ups for each challenge, with most modules offering multiple problems per topic so learners can apply an attack technique to different iterations. The course uses only free and open source tools, and its static site is built with mdbook.
Stanford Engineering Everywhere is an online offering of Stanford engineering courses available to students and educators at no charge. Its course portfolio includes a three-course Introduction to Computer Science sequence and more advanced courses in artificial intelligence and electrical engineering. Lecture videos can be streamed or downloaded, and full course materials include syllabi, handouts, homework and exams.
A beginner's guide to capture the flag (CTF) hacking competitions. It explains what a CTF is, describes jeopardy-style CTF categories such as reverse engineering, Pwn, crypto and web, and covers logistics, finding CTFs and reverse engineering resources.
CTFlearn is a platform for learning and competing in capture-the-flag challenges. It offers hundreds of challenges for testing skills and a community for learning cybersecurity with others, and describes itself as a beginner-friendly way into hacking. A free account can be created.
