About
API Security
Test API endpoints for security vulnerabilities across REST, GraphQL, WebSocket, and LLM-integrated APIs.
Techniques
| Type | Key Vectors | |------|-------------| | GraphQL | Introspection, batching attacks, nested query DoS, field suggestion | | REST API | BOLA/IDOR, mass assignment, rate limiting, auth bypass, versioning | | WebSocket | Cross-site hijacking, message manipulation, auth flaws | | Web-LLM | Prompt injection via API, excessive agency, data exfiltration |
Workflow
- Discover API endpoints and documentation (Swagger, GraphQL schema)
- Map authentication and authorization mechanisms
- Test per API type using appropriate techniques
- Validate data exposure and access control flaws
- Capture evidence with HTTP request/response logs
