Course Curriculum

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.

Frequently Asked Questions

API penetration testing is a security assessment where ethical hackers simulate attacks on APIs to identify vulnerabilities before malicious actors exploit them.
APIs are prime targets for attacks; testing helps prevent data breaches, unauthorized access, and service disruptions.
REST, SOAP, GraphQL, and gRPC APIs are commonly tested for security flaws.
A course in Python covers mainly the basics, web development with Django, data science, machine learning and advanced concepts.
BOLA, Broken Authentication, Injection, Excessive Data Exposure, and Misconfigurations (OWASP API Top 10).
API testing focuses on backend logic, data exchange, and endpoints, while web testing covers UI, cookies, and frontend flaws.
No, black-box testing is common, but white-box (with code access) provides deeper insights.
At least annually or after major updates, but critical systems may require quarterly tests.
Functional testing checks if APIs work correctly, while pentesting focuses on security weaknesses.
Yes, tools like Burp Suite and OWASP ZAP can automate scans, but manual testing is still crucial.
