Mobile Application Testing
Tested like an attacker.Fixed like an engineer.
Who this is for
Banking & fintech apps
Mobile apps handling payments, banking, or sensitive customer data on iOS and Android.
Health & wellness apps
Apps storing PHI or operating in regulated healthcare contexts.
App store reviews
Apps needing security evidence to satisfy Apple or Google app store security review processes.
What is mobile app penetration testing?
The structured assessment of iOS and Android applications for exploitable security weaknesses.
It combines static analysis of the application binary, dynamic analysis of the running application (instrumented via Frida or similar), local storage and IPC review, and network traffic analysis against the API backend.
OWASP Mobile Top 10 (M1–M10)
What mobile testing delivers
- OWASP Mobile Top 10 coverage across iOS and Android
- Static and dynamic binary analysis
- Local storage and keychain security review
- Certificate pinning and TLS implementation review
- API backend testing for the mobile-specific attack surface
- Remediation guidance directly actionable by mobile devs
Modern mobile testing must cover both the on-device application and the API backend — testing one without the other misses most exploitable issues.
Why mobile testing matters
Mobile apps now carry an outsized share of customer interaction and sensitive data flow for many organisations. They handle authentication credentials, payment tokens, personal health information, and direct API access to backend systems — all on devices that attackers can root, jailbreak, instrument, and decompile.
Mobile security weaknesses regularly enable serious incidents: stolen API tokens enabling account takeover, hardcoded secrets in shipped binaries, bypassable certificate pinning enabling MITM, weak local encryption exposing offline data. These issues are findable with proper testing and fixable with proper guidance.
Common consequences of weak mobile security
- API tokens stolen from insecure local storage
- Hardcoded API keys and secrets in shipped binaries
- Bypassed certificate pinning enabling MITM attacks
- Sensitive data exposure in offline storage
- Authentication bypass via local manipulation
- Compliance failures across PCI DSS and HIPAA
Mobile testing is essential for any customer-facing app handling sensitive data — the attack scenarios are real and the fixes are tractable.
Who needs mobile app testing?
Any organisation shipping iOS or Android apps that handle sensitive data, payments, or authentication should test regularly:
Banking & fintech mobile apps
Payment & wallet apps
HealthTech & telemedicine
E-commerce & retail apps
Enterprise SaaS mobile clients
Social & consumer apps
Streaming & content apps
Government & defence apps
Apple and Google app store review processes do not constitute security testing — they check policy compliance, not exploitable vulnerabilities. Dedicated mobile pentesting is the only meaningful pre-release security gate.
How we work
Our Mobile Testing Methodology
CREST-aligned methodology aligned to OWASP MASVS (Mobile Application Security Verification Standard) and MASTG (Mobile Application Security Testing Guide).
Scoping & Build Acquisition. We agree the in-scope app (iOS, Android, or both), test build availability (development or production binaries), test accounts, and any out-of-scope features.
Static Binary Analysis. Decompilation and static analysis of the app binary, hunting for hardcoded secrets, weak cryptography, insecure dependencies, and code-level vulnerabilities.
Local Storage Review. Examination of all on-device data — keychain entries, shared preferences, SQLite databases, files, IPC mechanisms — looking for sensitive data exposure.
Runtime Instrumentation. Dynamic analysis using Frida, Objection, or similar, testing runtime behaviour, bypassing client-side controls, examining function calls and crypto operations.
Certificate Pinning & TLS. Testing certificate pinning effectiveness, TLS configuration, and the attack scenarios that bypass typical pinning implementations.
API Backend Testing. Testing the API backend the app communicates with — typically where most exploitable issues live — with the mobile app as a useful client for exploration.
Reporting & Developer Walk-Through. Detailed findings with iOS/Android-specific reproduction steps, code-level remediation guidance, and live walk-through with your mobile team.
Remediation Retest. Critical and high findings re-tested in a new build after remediation, with documented validation for compliance evidence.
Typical engagement: 5–8 days for a single platform (iOS or Android), 10–15 days for combined iOS + Android testing with shared backend.
