API Pentesting Methodology

API penetration testing is crucial due to the high number of attacks on web applications through API vulnerabilities. Securing APIs can be complex, and attackers often use recursive fuzzing tools to target deprecated versions or legacy endpoints. The top five attacks to address are broken object-level authorization, injection attacks, excessive data exposure, lack of rate limiting, and security misconfiguration.

The methodology for API pen-testing involves scoping the API, addressing the top five attacks, reporting vulnerabilities, re-testing periodically, and publishing reports. Scoping consists of understanding the API, its versions, and its roles and having thorough documentation.
