BUGCROWD UNIVERSITYAPI Security Testing For HackersBy : SadakoIn this talk, I will be discussing the primary domains of API security, with notable examples of security flaws for each. I will also discuss some basic methodology for testing and fuzzing services, by approaching with educated guesses to how the backend actually works. Finally, I will discuss two major bugs that I was involved in finding, and the domains in which they fall under, discussing methodology and impact. I plan to have a follow up page on my website with links to resources for people who want to explore this space more. This talk is aimed more at the beginner audience, with some intermediate concepts involved.
