Pen Testing / API
API
penetration testing.
REST, GraphQL, and gRPC interfaces tested against the OWASP API Security Top 10 — broken object-level authorization, mass assignment, rate-limit bypass, schema introspection abuse, and business-logic exploitation.
A deep, contract-driven assessment of your APIs — every endpoint, every method, every role. We work from OpenAPI/GraphQL schemas where available, and we fuzz the seams when they’re not. Authentication, authorization, input validation, and business logic — all exercised.
APIs are how modern breaches happen. They’re hard to inventory, easy to misconfigure, and almost never tested as rigorously as the UIs in front of them. Broken Object-Level Authorization alone has been responsible for nine-figure breaches at companies with mature security programs.
Every category exercised — BOLA, broken authentication, broken object property level authorization, unrestricted resource consumption, and more.
OpenAPI 3, GraphQL introspection, and gRPC reflection consumed for comprehensive coverage.
We test what your APIs are supposed to do — and exploit what they shouldn’t.
How we run the engagement.
Schema ingestion & inventory
OpenAPI, GraphQL, Postman collections, gRPC reflection — full inventory before any traffic.
Authentication & authorization
Token analysis, JWT abuse, OAuth flow review, role-matrix testing across every endpoint.
Input & business logic abuse
Mass assignment, parameter pollution, type confusion, race conditions, workflow bypass.
Reporting & remediation
Per-endpoint findings, reproducible curl/HTTP requests, remediation walkthrough with your API team.
