AI Pentesting
Automated API penetration testing for REST and GraphQL.
Vezraa provides autonomous AI pentesting that actively probes, exploits, and validates security weaknesses. Our API testing targets your backend endpoints directly.
What API testing covers
- Authentication and authorization — token validation, session management, role bypass
- Injection attacks — SQL, NoSQL, command injection through API parameters
- Mass assignment — testing for unprotected fields that accept unexpected input
- Rate limiting — identifying endpoints vulnerable to brute force and DoS
- Business logic abuse — manipulating API workflows to bypass restrictions
- GraphQL-specific — introspection leaks, depth-based DoS, batching attacks
REST API testing
- HTTP method tampering — testing unexpected PUT, DELETE, PATCH against GET endpoints
- Parameter pollution — duplicate parameters, type coercion, array injection
- IDOR testing — sequential and predictable resource identifiers
- Content type confusion — switching between JSON, XML, form-data to bypass parsers
- JWT analysis — algorithm confusion, weak signing keys, claims manipulation
GraphQL API testing
- Introspection query abuse — extracting full schema to find hidden types and mutations
- Deeply nested queries — crafting queries that cause performance degradation (DoS)
- Batch query attacks — abusing batching to bypass rate limits per operation
- Authorization testing — accessing fields and mutations across type hierarchies
- Input type fuzzing — unexpected values for custom scalar types and enums
API authentication and authorization testing
- API key strength — testing for predictable keys and key rotation vulnerabilities
- OAuth 2.0 / OIDC — redirect URI manipulation, code injection, scope escalation
- Session token analysis — entropy testing, timing attacks, token leak detection
- Role-based access — testing each endpoint with different role credentials
- Permission inheritance — testing that revoked permissions don't persist
Integrating API testing into your workflow
- Provide OpenAPI / Swagger spec or let the agent discover endpoints automatically
- Configure authentication credentials for authenticated endpoint testing
- Run API-only scans without UI crawling for microservices and backend systems
- Webhook notifications for critical API vulnerabilities detected in real time
- CI/CD integration — block deployments that introduce new API vulnerabilities
