Offensive Security

    AI-POWERED API SECURITY TESTING

    APIs are the new attack surface. Faltrox Security utilizes AI-driven fuzzing to uncover complex logic flaws in REST, GraphQL, and gRPC endpoints. We go beyond simple vulnerability scanning to simulate sophisticated BOLA, Mass Assignment, and Injection attacks, securing the nervous system of your digital enterprise.

    Overview

    Why Does API Security Testing Matter?

    APIs are one of the fastest-growing attack surfaces. Traditional WAFs cannot detect logic flaws like BOLA (accessing another user's data) or Mass Assignment (privilege escalation via hidden fields).

    Our AI-Augmented Testing engines learn your API's business logic. They understand that user_id=105 shouldn't be able to delete user_id=106, finding authorization gaps that standard tools miss.

    We combine this machine speed with human creativity to craft complex, multi-step exploits that prove the real-world impact of an API breach.

    06

    Bot Defense

    Testing if your API can withstand automated scraping and credential stuffing.

    Methodology variants

    Testing Approaches

    We adapt the test based on the documentation provided.

    No Documentation

    BLACK BOX

    We reverse engineer your API by intercepting traffic from your mobile or web app. Maximum real-world simulation: zero prior knowledge, pure enumeration.

    Postman Collection

    GREY BOX

    Valid user credentials and basic documentation to speed up coverage. The most common engagement, balancing depth with efficiency across the OWASP API Top 10.

    OpenAPI + Source

    WHITE BOX

    Full Swagger/OpenAPI spec plus source code. We analyze the backend logic for hidden endpoints, dead code paths, and flaws no scanner can surface.

    Process

    Our API Pentesting Process

    A rigorous 6-step testing lifecycle designed for APIs.

    1. 01

      RECONNAISSANCE

      Enumerating endpoints, standardizing versions (v1, v2), and finding undocumented routes.

    2. 02

      AUTH ANALYSIS

      Deep testing of JWTs (Weak Secrets), OAuth2 flows, and Session Management.

    3. 03

      LOGIC MAPPING

      Understanding user roles and identifying high-value business logic (e.g., transfers, password resets).

    4. 04

      EXPLOITATION

      Executing BOLA, BFLA, and Mass Assignment attacks to bypass authorization controls.

    5. 05

      REPORTING

      Documenting every request/response pair to make remediation easy for developers.

    6. 06

      VERIFICATION

      Retesting fixes to ensure the vulnerability is truly closed.

    Scope

    Threat Vectors

    We cover the entire OWASP API Security Top 10.

    01critical

    BOLA / IDOR

    Accessing other users' data by changing an ID in the API call.

    02critical

    Mass Assignment

    Overwriting critical fields (e.g., 'isAdmin': true) via API inputs.

    03high

    Injection

    SQLi or Command Injection passed through API parameters.

    04medium

    Improper Assets

    Exposed v1 (deprecated) APIs or staging endpoints.

    Outcomes

    Key benefits

    Secure your data at the source.

    Protect User Data

    Prevent massive data leaks caused by simple authorization flaws (BOLA). The single highest-impact win in API security, and the one tools miss most often.

    Pass Audits

    Satisfy requirements for PCI-DSS 6.5 and SOC 2 application security testing.

    Enable Innovation

    Release new features faster knowing your core API logic is secure.

    Partner Trust

    Give your B2B partners confidence that their data separation is enforced.

    Stop Bot Abuse

    Identify rate-limiting gaps that allow scrapers to steal your content.

    Full Stack Security

    Secure not just the API, but the underlying cloud and database connections.

    FAQ

    Common questions

    01Do you support GraphQL?

    Yes. We have specialized modules for GraphQL introspection analysis, query depth limiting checks, and batching attacks, in addition to standard REST API coverage.

    02Can you scan internal microservices?

    Absolutely. We can connect via VPN or deploy a containerized scanner agent within your Kubernetes cluster to test internal service-to-service communication.

    03What is BOLA/IDOR?

    Broken Object Level Authorization (BOLA), often called IDOR, allows User A to access User B's data by changing an ID. It is the #1 API threat, and we manually test every endpoint for it.

    04How do you handle authentication?

    We test all auth mechanisms including JWT, OAuth2, OIDC, and API Keys. We check for weak signing, token leakage, and scope escalation.

    05What do you need to start?

    A Postman Collection or Swagger/OpenAPI file is best. If not, we can crawl your web app to discover endpoints, but accurate documentation yields better results.

    06Do you test for Rate Limiting?

    Yes. We verify that your API appropriately blocks excessive requests to prevent DoS attacks and brute-force attempts.

    07Is this automated or manual?

    Primarily manual. Tools are bad at understanding business logic (e.g., 'User A should not see User B's orders'). We use tools for fuzzing, but manual testing for logic.
