iOS Application Penetration Testing Report — Sample

This is a fictional, illustrative sample of an iOS application penetration testing report. It demonstrates how TMG Security structures and documents a professional iOS application security assessment — from scope and OWASP MASVS-aligned methodology through static and dynamic analysis, mobile-API integration testing, findings, risk analysis, and remediation guidance. The full sample report contains 47 illustrative findings drawn from 150 fictional test cases, mapped against all 8 current OWASP MASVS control groups (24 individual controls), with traceability to OWASP MASTG v2.0.0 and OWASP MASWE v1.0.0. NovaSphere Digital Technologies, Inc. and its NovaSphere Pay iOS application do not exist; every finding, test case, and figure in this sample is fictional and constructed to show TMG's reporting standard, not to describe any real organization's security posture.

The fictional NovaSphere Pay iOS client is distributed as NovaSpherePay-6.4.2.ipa (version 6.4.2, build 6402) and talks to two fictional, non-resolving backend hosts: a primary payments API and a dedicated authentication service. This sample report shows how TMG documents application and platform metadata as the baseline for every subsequent test.

Scope for this fictional assessment covered the full iOS client and its supporting mobile API, exercised over a 17 August 2026 – 08 September 2026 assessment window against 150 fictional test cases. Testing combined static analysis of the IPA with dynamic, on-device assessment and direct mobile-API testing.

TMG Security's iOS testing approach is conceptually informed by the OWASP Mobile Application Security Verification Standard (MASVS), the OWASP Mobile Application Security Testing Guide (MASTG) v2.0.0, and the OWASP Mobile Application Security Weakness Enumeration (MASWE) v1.0.0. Testing covered all 8 current MASVS control groups, spanning 24 individual MASVS controls: storage, cryptography, authentication, network communication, platform interaction, code quality, resilience, and privacy.

TMG Security is not affiliated with, endorsed by, reviewed by, or certified by OWASP. This report is not an OWASP-certified assessment, an official OWASP audit, or evidence of any OWASP accreditation, and no copyrighted OWASP material is reproduced in this document — the frameworks above are cited only as conceptual, methodological grounding for TMG's own independent testing approach.

Once an iOS application is installed, its IPA, local storage, and runtime behavior are all within reach of whoever controls the device — which changes what the application can safely treat as a trust boundary. Anything checked only on the client, whether a Face ID prompt, a client-side signature check, or a boolean flag set after a LocalAuthentication callback, is a user-experience feature rather than a security control: on a jailbroken or instrumented device, that check can be bypassed entirely, and any other app installed on the same device can attempt to interact with it through iOS's own inter-app communication mechanisms — custom URL schemes, Universal Links, App Groups, and extensions.

NovaSphere Pay's own trust boundary sits at three points repeated throughout this report: the boundary between the app's Keychain / sandboxed storage and the rest of the device; the boundary between the app and other installed applications (governed by URL scheme and Universal Link validation, App Extension and App Group data isolation, and WKWebView JavaScript-bridge scoping); and the boundary between the mobile client and its backend API (governed by whether the server independently re-verifies every authorization decision the client believes it has already made). The most severe findings in this assessment sit directly on one of these three boundaries.

TMG Security reviewed the fictional NovaSphere Pay IPA's Info.plist, entitlements, provisioning profile, and code-signing configuration, then reviewed the decompiled Mach-O binary and Swift/Objective-C source for hardcoded secrets, debug artifacts, and insecure coding patterns.

TMG Security reviewed NovaSphere Pay's App Extensions, App Group container configuration, and Handoff / SiriKit & App Intents surface — assessing whether shared containers and extensions expose more than their documented cross-app purpose requires.

TMG Security tested NovaSphere Pay's custom URL scheme and its equivalent Universal Link for sensitive account-modifying actions reachable without in-app confirmation, and the in-app support WKWebView's JavaScript-bridge exposure and navigation scoping.

TMG Security inspected every form of on-device persistence NovaSphere Pay uses for sensitive data: the iOS Keychain, local database storage, the HTTP response cache, background-snapshot capture, the system pasteboard, and Data Protection entitlement configuration.

TMG Security reviewed NovaSphere Pay's use of cryptographic primitives, Secure Enclave / Keychain-backed key storage, and random-value generation for security-relevant data. Cryptographic keys used for local field-level encryption are correctly generated and held using platform-provided key storage rather than a custom or home-grown cryptographic implementation — a genuine positive control. Testing did not identify a confirmed weakness in NovaSphere Pay's core cryptographic key-management implementation in this fictional sample.

TMG Security reviewed NovaSphere Pay's App Transport Security (ATS) configuration and tested TLS enforcement and certificate validation across every network client the app uses, via a fictional interception-proxy host on an isolated test network.

TMG Security assessed NovaSphere Pay's login, session-timeout, logout/token-revocation, and Face ID / Touch ID (LocalAuthentication) flows. Multi-factor authentication is correctly and consistently enforced for all standard login flows with no client-side bypass path identified — a genuine positive control.

Mobile-API integration testing — exercising the backend endpoints NovaSphere Pay's mobile client depends on directly, independent of the app's own UI — was the single most significant category in this fictional assessment. Server-side object-level authorization is otherwise enforced correctly on the majority of endpoints tested; the confirmed authorization gap below is concentrated specifically in one mobile-only workflow.

TMG Security assessed NovaSphere Pay's posture against OWASP MASVS-RESILIENCE — the set of controls intended to slow static and dynamic reverse engineering, detect tampering and repackaging, and resist execution in a jailbroken, emulated, or debugged environment. Consistent with MASVS's own guidance that resilience controls are explicitly defense-in-depth, no finding in this category is rated above High for that reason alone.

TMG Security assessed NovaSphere Pay against OWASP MASVS-PRIVACY — permission minimization, handling of personally identifiable information collected during fictional account onboarding, and third-party SDK / analytics behavior. PII collected during onboarding is transmitted only over the TLS-protected primary API channel and is not retained locally beyond the active onboarding session — a genuine positive control.

This fictional assessment identified 47 illustrative findings across NovaSphere Pay's iOS client and its supporting mobile-API integration, drawn from 150 fictional test cases mapped against 24 OWASP MASVS controls across eight control groups. Every finding, severity rating, and evidence reference below is fictional and specific to this iOS penetration test — none are drawn from any other TMG sample report. The complete finding register (all 47 findings) is included in the full sample PDF; the selection below is illustrative rather than exhaustive.

The full sample report plots all 47 fictional findings on a likelihood/impact heatmap and walks through two illustrative attack chains: one combining the insecure Universal Link flow (IOS-004) with the local-storage token exposure (IOS-001) to show how a single crafted link plus device compromise could escalate to account takeover, and a second combining the mobile-API authorization gap (IOS-003) with weak biometric enforcement (IOS-013) to show how a compromised device could reach another customer's account data through the mobile API alone.

These attack-chain narratives are illustrative of TMG's reporting approach and do not describe any real exploitation — no real application, backend, or device was tested.

The full sample report frames each Critical and High finding in fictional business terms — for example, translating the insecure Universal Link finding (IOS-004) into potential fraud exposure through unauthorized payee additions, and the mobile-API authorization gap (IOS-003) into potential cross-customer data exposure — so that a fictional NovaSphere leadership team could prioritize remediation against illustrative business risk rather than technical severity alone.

Every finding in the full sample report carries an owning fictional role, a target remediation date, and a status (Remediation In Progress, Remediation Planned, or Retest Required), grouped into a phased roadmap: immediate actions for the four Critical findings, a 30-day phase for the nine High findings, and a 90-day phase for Medium, Low, and Informational findings, consistent with the remediation-tracking pattern used across TMG's sample reports.

The full sample report closes its technical body with a management-facing action plan summarizing ownership and target dates by severity band, and a retest recommendation scoping a focused validation pass against the four Critical and nine High findings ahead of a full retest of the remaining findings, mirroring the retest structure used in TMG's other sample reports.

Beyond the 79 numbered technical and reporting sections summarized on this page, the complete sample PDF includes a full set of supporting appendices:

TMG Security's iOS methodology runs in stages: acquire and statically analyze the IPA (Info.plist, entitlements, provisioning profile, code signing, Mach-O and decompiled source); assess on-device local storage, Keychain, and cryptography; test authentication, session, and biometric enforcement; test network security (ATS, TLS, certificate pinning); test URL schemes, Universal Links, WKWebView, and App Extension / App Group surfaces; test the mobile API directly for authorization and business-logic gaps; assess resilience (jailbreak detection, anti-debugging, anti-tampering) and privacy controls; then validate every candidate finding manually before it is mapped to OWASP MASVS/MASTG/MASWE, rated for severity, and written up with evidence and remediation guidance.

This fictional assessment also documents genuine positive controls in NovaSphere Pay's design: consistently enforced multi-factor authentication with no client-side bypass identified, platform-backed (rather than custom) cryptographic key storage, and TLS/certificate pinning correctly enforced on the primary payments API client. Testing was strictly non-destructive and used only dedicated fictional test accounts and devices; no real user accounts, signing keys, or customer data were used at any point, and this sample does not represent a complete or exhaustive test of every possible iOS attack surface.

This sample shows how TMG Security structures an iOS application penetration test. TMG also provides Mobile Application Security Testing, API Security Testing, Web Application Security Testing, and Offensive Security & Penetration Testing for organizations that need an actual assessment of a real application.
