Mobile Application Penetration Testing

Flow chart of the Mobile Application engagement, 6 phases in order, each one selectable. Phase 1, Scoping and Rules of Engagement. We agree the Android and iOS builds, test accounts and backend endpoints in scope, then set devices and testing windows. Activities: Confirm Android and iOS builds in scope; Provision test accounts and backend endpoints; Agree instrumented test devices; Set testing windows and contacts. Hands over Signed Rules of Engagement. Phase 2, Static Analysis. We decompile and inspect the app for hardcoded secrets, weak crypto, insecure storage and unsafe configuration on both platforms. Activities: Decompile the Android and iOS binaries; Hunt for hardcoded secrets and keys; Review local storage and crypto use; Check platform configuration flags. Hands over Static Analysis Findings. Phase 3, Dynamic Analysis. We run the app on instrumented devices, intercept its traffic and observe how it handles data, sessions and platform APIs at runtime. Activities: Run the app on instrumented devices; Intercept and inspect network traffic; Observe runtime data and session handling; Trace calls to platform APIs. Hands over Runtime Behaviour Findings. Phase 4, Manual Exploitation and Platform Checks. We attempt bypasses of root and jailbreak detection, certificate pinning, biometric and local auth, and abuse the app's own logic. Activities: Bypass root and jailbreak detection; Defeat certificate pinning with Frida; Attack biometric and local auth; Abuse the app's own business logic. Hands over Proven Client-Side Findings. Phase 5, Backend and Impact. We test the API behind the app and show how device-side and server-side flaws combine into real impact on accounts and data. Activities: Test the backend API the app calls; Chain device-side and server-side flaws; Map exposed accounts and data; Assess combined business impact. Hands over Impact and Risk Assessment. Phase 6, Reporting and Verified Retest. You get a report with proof of concept per platform and clear fixes, and we retest once you remediate to confirm closure. Activities: Write per-platform findings and fixes; Produce an executive summary; Walk your team through the results; Retest fixes and confirm closure. Hands over Final Report and Verified Retest. Each phase begins from the artefact the phase before it produced.
