Mobile Application & API
Penetration Testing

Secure the App. Protect the API. Strengthen the Ecosystem.

Our Mobile Application & API Penetration Testing service assesses the complete mobile application ecosystem—from the mobile client and locally stored data to backend APIs, authentication mechanisms, and supporting services. We combine dynamic analysis, reverse engineering, API security testing, and expert-led manual exploitation to identify vulnerabilities that could expose sensitive information, compromise user accounts, bypass security controls, or impact critical backend functionality.

Mobile Application Security &Runtime AnalysisWe assess the mobile application itself to identify weaknesses inits implementation, runtime behavior, local data protection, andsecurity controls. Testing covers both static characteristics of theapplication and its behavior during execution.Android & iOS AssessmentAssess Android and iOS applications for implementation and security-controlweaknesses.APK/IPA Reverse EngineeringAnalyze APK/IPA packages and reverse engineer the client to uncover hidden risks.Insecure Local Data StorageEvaluate local data storage for insecure handling of sensitive information on device.Hardcoded Secrets & KeysIdentify hardcoded secrets, keys, and sensitive information embedded in theapplication.Runtime Manipulation & TamperingAssess runtime manipulation and tampering risks during live application execution.Root/Jailbreak Bypass TestingTest root/jailbreak detection and application protection bypass techniques.

Mobile Application Security & Runtime Analysis

We assess the mobile application itself to identify weaknesses in its implementation, runtime behavior, local data protection, and security controls. Testing covers both static characteristics of the application and its behavior during execution.

  • Android & iOS Assessment

    Assess Android and iOS applications for implementation and security-control weaknesses.

  • APK/IPA Reverse Engineering

    Analyze APK/IPA packages and reverse engineer the client to uncover hidden risks.

  • Insecure Local Data Storage

    Evaluate local data storage for insecure handling of sensitive information on device.

  • Hardcoded Secrets & Keys

    Identify hardcoded secrets, keys, and sensitive information embedded in the application.

  • Runtime Manipulation & Tampering

    Assess runtime manipulation and tampering risks during live application execution.

  • Root/Jailbreak Bypass Testing

    Test root/jailbreak detection and application protection bypass techniques.

We identify and assess the APIs exposed by theapplication, including documented, undocumented, legacy, andhidden endpoints.API Endpoint DiscoveryDiscover API endpoints and map the backend attack surface used by the mobile client.REST, SOAP & GraphQL TestingTest REST, SOAP, and GraphQL APIs supporting the mobile application ecosystem.Auth & Token ValidationAssess API authentication and token validation controls across mobile-driven flows.Parameter & Input ValidationEvaluate API parameter handling and input validation for injection and abuse paths.Excessive Data ExposureIdentify excessive data exposure in API responses beyond what the mobile client needs.Versioning & Legacy EndpointsAssess API versioning and legacy endpoint security that may retain weaker controls.

API & Backend Attack Surface

The mobile application is only as secure as the backend services supporting it. We identify and assess the APIs exposed by the application, including documented, undocumented, legacy, and hidden endpoints.

  • API Endpoint Discovery

    Discover API endpoints and map the backend attack surface used by the mobile client.

  • REST, SOAP & GraphQL Testing

    Test REST, SOAP, and GraphQL APIs supporting the mobile application ecosystem.

  • Auth & Token Validation

    Assess API authentication and token validation controls across mobile-driven flows.

  • Parameter & Input Validation

    Evaluate API parameter handling and input validation for injection and abuse paths.

  • Excessive Data Exposure

    Identify excessive data exposure in API responses beyond what the mobile client needs.

  • Versioning & Legacy Endpoints

    Assess API versioning and legacy endpoint security that may retain weaker controls.

Identity, Access & Data ProtectionWe evaluate how the mobile application and APIs protect useridentities, sessions, privileges, and sensitive informationthroughout the application lifecycle.Authentication & MFA BypassTest authentication and MFA controls for bypass opportunities across mobile and APIflows.OAuth, JWT & Token SecurityAssess OAuth, JWT, and token security for abuse, replay, and validation weaknesses.BOLA / IDOR TestingTest Broken Object Level Authorization to detect unauthorized access to objects andrecords.BFLA TestingTest Broken Function Level Authorization across privileged and unprivileged functions.Session & Token LifecycleEvaluate session management and token lifecycle controls across the applicationlifecycle.Data Exposure & EncryptionAssess sensitive data exposure and encryption effectiveness on device and in transit.
