Authorization (BOLA & BFLA)
API1:2023 Broken Object Level Authorization and API5:2023 Broken Function Level Authorization — the two highest-impact API bugs. Tested with multiple user/tenant accounts and role-permutation matrices.
// API VAPT
API Security TestingServices in Pakistan.
REST, GraphQL, gRPC and WebSocket API penetration testing aligned with the OWASP API Security Top 10. BOLA, BFLA, mass assignment, JWT flaws, rate limiting, injection — for Pakistani teams whose APIs power Western clients' production systems.
// what we test
OWASP API Security Top 10 — and Beyond
API bugs are almost never caught by scanners. Every endpoint is reviewed manually with multi-role test accounts.
Authentication & tokens
JWT algorithm confusion, signature stripping, weak secrets, token reuse, refresh-token rotation flaws, OAuth scope abuse, mTLS misconfiguration, API-key handling.
Mass assignment & data exposure
API3 excessive data exposure, API6 mass assignment, leaky PATCH endpoints, hidden fields, debug routes, verbose error responses, sensitive data in logs.
Rate limiting & injection
Bypass via headers / casing / encoding, business-logic DoS, GraphQL query-depth abuse, SQL/NoSQL/command injection in JSON, XXE in XML endpoints, server-side request forgery (SSRF).
// protocols & specs
Protocols We Test
- REST: JSON, XML, multipart, OpenAPI / Swagger spec-driven coverage with multi-role test accounts.
- GraphQL: Schema introspection abuse, query depth/complexity attacks, batched-query abuse, authorization at the resolver level.
- gRPC: Reflection-enabled enumeration, proto fuzzing via grpcurl / Postman, metadata-based auth flaws.
- WebSocket: Origin handling, authentication on upgrade, cross-site WebSocket hijacking.
- Webhooks: Signature verification, replay protection, SSRF inside webhook receivers.
// tooling
Tools We Use
Discovery & spec ingestion
Postman / Bruno, Swagger / OpenAPI parsers, Burp Suite Pro extensions (Autorize, JWT Editor, GraphQL Raider), Kiterunner for hidden routes.
Exploitation
Burp Repeater + Intruder, custom Python with httpx / requests, grpcurl, jwt_tool, GraphQL Voyager / InQL, race-condition tooling via Turbo Intruder.
