API Hacking Course Modules
Learn modern API security testing techniques including endpoint enumeration, authentication bypass, injection attacks, BOLA vulnerabilities, OAuth/JWT weaknesses, and full real-world API penetration testing workflows.
Introduction to REST APIs and JSON Structure
Understand the architecture of the modern web. This module covers RESTful principles and JSON data formats, teaching you how applications exchange data and where security vulnerabilities typically hide.
Understanding API Endpoints and Methods
Master the various ways to interact with an API. Learn how GET, POST, PUT, and DELETE methods function and how to identify sensitive endpoints that might expose private data.
Enumerating API Endpoints and Parameters
Learn to map out the hidden surface of an API. This module focuses on fuzzing and discovery techniques to find undocumented endpoints and parameters that developers often leave unprotected.
Identifying Broken Object Level Authorization (BOLA)
Master the most common API flaw. Learn how BOLA allows attackers to access unauthorized data by simply changing an ID in a request, and how to identify these critical gaps.
Exploiting Common API Vulnerabilities
Explore a range of flaws including Mass Assignment and Improper Assets Management. Learn how these logic bugs allow attackers to modify sensitive account details or access deprecated, insecure versions.
Injection Attacks in APIs (SQLi, Command Injection, XXE)
Understand how SQLi, Command Injection, and XXE manifest in API environments. Learn to craft payloads specifically designed for JSON and XML inputs to compromise back-end databases and servers.
API Testing with Postman
Master Postman for professional security assessments. Learn to automate requests, manage collections, and script tests to efficiently identify vulnerabilities across complex, multi-layered API infrastructures and microservices.
API Analysis using Burp Suite
Leverage Burp Suite to intercept and manipulate API traffic. Learn to use the Repeater and Intruder tools to test how the server handles malformed data and unauthorized requests.
Exploiting API Authentication Flaws
Analyze weak login mechanisms in APIs. This module covers credential stuffing and session management flaws, teaching you how to bypass authentication and gain unauthorized access to secure user data.
API Security Best Practices (OAuth 2.0, JWT)
Master modern security standards like OAuth 2.0 and JSON Web Tokens. Learn how to correctly implement and test these protocols to ensure secure authorization and data integrity.
API Hardening and Mitigation Techniques
Learn to defend APIs against common threats. Master rate limiting, input validation, and proper error handling to ensure your application remains resilient against both automated and manual attacks.
Final Lab: Performing a Complete API Penetration Test
Apply your skills in a realistic simulation. Conduct a full API security audit, from initial discovery to final exploitation, ensuring you are ready to handle real-world security challenges.
