Mobile Application Penetration Testing
Securexocean's mobile application security testing delivers a comprehensive assessment covering client-side vulnerabilities, backend API security, and data storage risks across Android and iOS platforms.
SERVICE INTRODUCTION
Securexocean tests against OWASP Mobile Security Testing Guide and OWASP MASVS methodologies across both Android and iOS platforms, executed by certified practitioners with hands-on mobile security experience across fintech, healthcare, and SaaS environments.
THREAT LANDSCAPE
Mobile applications introduce attack surfaces that web testing alone does not address. Client-side code is directly accessible through reverse engineering. Sensitive data is frequently stored insecurely on the device itself. Backend APIs serving mobile apps are often less hardened than those serving web interfaces. Certificate validation is regularly misconfigured, enabling traffic interception on untrusted networks.
Fintech and healthcare applications carry the highest exposure given the volume and sensitivity of financial and health data they handle on-device and transmit to backend systems. Attackers targeting mobile applications often combine client-side reverse engineering with backend API enumeration to maximize impact.
WHAT WE IDENTIFY AND VALIDATE
Insecure local data storage including plaintext credentials and tokens in shared preferences, SQLite databases, and log files
Weak or absent certificate pinning enabling man-in-the-middle interception
Hardcoded API keys, credentials, and sensitive strings in application binaries
Insecure authentication and session token handling on client and server sides
Reverse engineering exposure through absent code obfuscation and binary protections
Broken access controls on backend APIs serving the mobile application
Insecure inter-app communication via exported activities, intents, and content providers
Clipboard data leakage and screenshot caching of sensitive application screens
Weak cryptographic implementations and insecure key storage practices
Runtime manipulation vulnerabilities on rooted or jailbroken devices
Platform coverage, authentication roles, backend API scope, and testing environment defined. Rules of engagement documented before work begins. NDA executed prior to build file transfer.
Binary decompilation and code analysis of the application identifying hardcoded secrets, insecure configurations, exposed components, and code-level vulnerabilities without executing the application.
Runtime testing in an instrumented environment covering network traffic interception, authentication flow analysis, session management behavior, and runtime manipulation assessment.
All API endpoints serving the mobile application assessed against OWASP API Security Top 10, covering authorization controls, input validation, rate limiting, and sensitive data exposure in API responses.
Manual exploitation of confirmed vulnerabilities to validate real-world impact. Attack chaining across client-side and server-side findings evaluated where applicable.
Severity-prioritized report with full exploitation evidence. Post-remediation retesting conducted and closure report issued for audit submission.
TOOLS AND TECHNIQUES
Our team uses static analysis frameworks for Android and iOS binary decompilation, dynamic instrumentation frameworks for runtime hooking and behavioral analysis, network interception proxies for traffic manipulation, rooted and jailbroken device environments for deep runtime assessment, and automated mobile scanning platforms for initial enumeration. All findings are manually validated. Automated output is a starting point, not a conclusion.
Executive summary covering mobile application risk posture for leadership stakeholders
Technical findings with CVSS v3.1 scores, reproduction steps, and screenshot or traffic capture evidence
Separate finding sections for Android, iOS, and backend API where all three are in scope
Compliance mapping against OWASP MASVS, ISO 27001, PCI DSS, or HIPAA where applicable
Remediation guidance specific to the platform, framework, and SDK in use
Post-remediation retest report confirming closure for audit submission
COMPLIANCE RELEVANCE
Control A.8.29 requires security testing across development and acceptance processes, applicable directly to mobile application release cycles.
Requirements 6.2 and 11.3 mandate vulnerability management and penetration testing for payment-handling mobile applications processing or transmitting cardholder data.
Technical Safeguard evaluation requirements under the Security Rule apply to mobile applications that access, store, or transmit electronic protected health information.
Engagements can be scoped to MASVS Level 1 or Level 2 verification for organizations requiring structured mobile security maturity validation aligned to their development standards.
