Mobile Application Penetration Testing

We assess your iOS and Android apps — and the APIs behind them — the way an attacker with a rooted device and a decompiler would.

Attack path focus LIVE

  • iOS and Android coverage
  • Static + dynamic analysis
  • Backend API testing included
  • Findings mapped to OWASP MASVS v2

Overview

Mobile apps run on devices you don't control. Anyone can download your app, decompile it, inspect what it stores, intercept its traffic and replay requests to your backend. A mobile penetration test measures how well your app and its APIs hold up under that scrutiny.

Our assessments combine static analysis of the app package, dynamic analysis on rooted and jailbroken test devices, and full testing of the backend APIs the app relies on — because once attackers understand your API, the app's client-side protections no longer matter.

Findings are mapped to the OWASP Mobile Application Security Verification Standard (MASVS v2), giving your iOS and Android developers platform-specific guidance they can act on.

What's included

Data storageTokens, PII and secrets in local storage, keychain/keystore, logs, caches and backups.
CryptographyHard-coded keys, weak algorithms and incorrect use of platform crypto APIs.
AuthenticationSession handling, biometrics, OTP flows and client-side-only checks.
Network communicationTLS validation, certificate pinning and cleartext traffic.
Platform interactionDeep links, exported components, WebViews and inter-app communication.
ResilienceRoot/jailbreak detection, anti-tampering and reverse-engineering resistance where required.

Our approach

  1. Static analysisDecompilation and review of manifests, plists, binaries and embedded secrets.
  2. Dynamic analysisRuntime instrumentation on test devices to inspect storage and bypass controls.
  3. Traffic interceptionManipulating API calls to test authentication, authorization and input handling.
  4. Business logicAbuse of in-app purchases, rewards, KYC and payment flows.
  5. Report & retestPlatform-specific fixes for iOS and Android teams, followed by verification.

  • CWE
  • RBI mobile banking guidelines (where applicable)

Frequently asked questions

Do we need to test both platforms?

Usually yes. iOS and Android differ in storage, permissions and security features, and codebases often diverge even with cross-platform frameworks.

Can you test Flutter and React Native apps?

Yes. Cross-platform apps need some different reverse-engineering tooling, but MASVS controls and API testing apply in the same way.

What builds should we provide?

Ideally both a debuggable build (faster, deeper testing) and the release build (to assess real-world protections).
