API Security & Penetration Testing
Hands-on security assessment identifying and exploiting API vulnerabilities including authentication bypasses, injection flaws, and authorization issues.
Overview
A hands-on security project focused on identifying and exploiting vulnerabilities in web APIs. The project covers the OWASP API Security Top 10, including broken authentication, excessive data exposure, and injection attacks, with practical exploitation techniques and secure coding recommendations.
Technologies
Key Features
- ✓API endpoint discovery and enumeration
- ✓Authentication mechanism analysis and bypass
- ✓JWT token manipulation attacks
- ✓SQL injection in API parameters
- ✓Authorization bypass testing
- ✓Security vulnerability documentation
Challenges
Understanding complex authentication mechanisms like OAuth and JWT, identifying subtle logic flaws in authorization, and developing reliable exploits that work across different API implementations.
Results
Successfully identified and exploited multiple security vulnerabilities, capturing all security flags. Achieved 100% score demonstrating comprehensive API security knowledge.
