REST, GRAPHQL & MICROSERVICES PENETRATION TESTING

Uncover Exploits in Your
APIs & Microservices

APIs power modern applications—and represent the primary target for modern data breaches. We execute deep logic-level penetration testing to eliminate BOLA, BFLA, broken authentication, and shadow endpoints.

[FUZZER_ACTIVE] Testing 342 Endpoints for OWASP API Top 10 Flaws...

OVERVIEW

Logic-Level API Penetration Testing

Traditional Web Application Firewalls (WAFs) inspect standard HTTP traffic signatures, but they are completely blind to Broken Object Level Authorization (BOLA) and business logic flaws. An attacker using valid credentials can easily manipulate object IDs to dump databases or elevate privileges across microservices.

Our offensive security engineers perform thorough, hands-on logic testing against your REST, GraphQL, and gRPC endpoints, uncovering authorization bypasses, rate limit evasions, and token vulnerabilities before production abuse occurs.

CAPABILITIES

Full API Security Audit Coverage

End-to-end security evaluations covering API gateways, microservice communication, and authentication handlers.

🔓

BOLA & BFLA Authorization Testing

Deep logic-level audits testing multi-tenant isolation, IDOR/BOLA bypasses, and privilege escalation across user roles.

⚡

REST, GraphQL & gRPC Protocol Security

Protocol-specific fuzzing, GraphQL introspection abuse, query batching limits, and gRPC Protobuf deserialization checks.

🔑

OAuth2 & JWT Token Manipulation

Assess token signature validation, algorithm confusion attacks, replay exploits, and scope restriction enforcement.

👁️

Shadow & Zombie API Discovery

Locate unmapped endpoints, deprecated API v1 versions left exposed, and undocumented staging microservices.

🛡️

API Rate-Limiting & DoS Resiliency

Stress-test API gateways against resource exhaustion, inventory hoarding, automated credential stuffing, and bot attacks.

📜

CI/CD & OpenAPI Spec Auditing

Continuous OpenAPI/Swagger specification linting and automated API security testing integrated into CI/CD pipelines.

METHODOLOGY

API Security Audit Lifecycle

A battle-tested process combining automated fuzzing with deep manual business-logic testing.

01
01 // AUDIT PHASE
API Reconnaissance & Schema Mapping
Extract endpoints from client JS bundles, mobile apps, OpenAPI/Postman specs, and proxy logs to build an API inventory.
02
02 // AUDIT PHASE
Authentication & Token Handshake Audit
Test OAuth2 grant flows, PKCE implementations, JWT validation, refresh token handling, and session revocation.
03
03 // AUDIT PHASE
Logic-Based BOLA / IDOR Exploitation
Execute systematic object identifier substitution across cross-tenant endpoints to discover unauthorized access vectors.
04
04 // AUDIT PHASE
Mass Assignment & Data Exposure Check
Inject hidden property payloads into REST JSON bodies to manipulate administrative fields (e.g., `is_admin: true`).
05
05 // AUDIT PHASE
Rate Limiting & Gateway Security Audit
Test header spoofing (X-Forwarded-For bypasses), distributed endpoint fuzzing, and API gateway web application firewall rules.
06
06 // AUDIT PHASE
Remediation & API Gateway Hardening
Provide exact code patches, Kong/Apigee/AWS API Gateway policy rules, and strict schema validation schemas.
