Need to learn the basics of hacking? HackerOne offers Hacker101 - a free online course about web security. The course is taught through video lessons where you don't have to go through the course in order, but you can simply watch the lessons on the topics that you want to learn about.
Explore a range of topics in the course, including report writing, Burp proxy setup, cookie security, clickjacking, and crypto attacks. Access all course material at https://www.hacker101.com/.
Hacker 101 also offers a Capture The Flag (CTF) game where you can hack and hunt for bugs in a safe environment. The CTF serves as the official coursework for the class. You can still access the old coursework on the GitHub repo.
Once you have earned 26 points in the CTF, you’ll be eligible to receive invitations to private programs.
