What it does
API security testing - GraphQL, REST API, WebSocket, and Web-LLM attack techniques.
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
API at scale (offline corpus / fixture-driven)
For a large or offline API surface, a 2000+ path Swagger, a Postman corpus, a HAR capture, do NOT hand-build the coverage machinery per engagement. Drive it deterministically:
