Mobile Application Security

Security assessment of Android and iOS applications — local storage, runtime protections, transport security, exported components and the APIs the app depends on.

The problem

Why this assessment matters

Mobile apps run on devices you do not control, frequently over untrusted networks, and carry tokens, personal data and business logic. Weak local storage, over-permissive components or an unvalidated deep link can turn a lost phone or a reverse-engineered APK into an entry point to your backend.

Scope

What We Test

Typical coverage for this assessment, tailored to your system during scoping.

  • Android
  • iOS
  • Local storage
  • Authentication
  • Certificate validation
  • Runtime security
  • Deep links
  • Exported components
  • API communication
Methodology

How the Assessment Runs

A consistent six-stage process — every stage produces something you can use.

  1. Discover

    Decompile the application, review the manifest and entitlements, map components, permissions, deep links and backend calls.

  2. Assess

    Test data storage, transport security, runtime protections, component exposure, IPC/intents, WebView behaviour and API usage.

  3. Validate

    Confirm exploitability on a controlled device or emulator with captured evidence — for example, extracting stored data or invoking an exported component.

  4. Report

    Document findings with file-level references, device or emulator steps, evidence and platform-specific remediation.

  5. Remediate

    Guide engineering on secure storage, certificate pinning, component hardening and backend-side controls.

  6. Retest

    Rebuild and re-verify fixed builds against the original findings.

Example outcomes

Typical Findings

Realistic issue classes commonly discovered during this type of assessment. Your results depend on your system — we do not imply guaranteed findings.

  • Sensitive data in unencrypted local storage or logs
  • Weak or missing certificate validation enabling MITM
  • Exported components reachable by other applications
  • Unsafe deep links or universal links bypassing authorization
  • Hardcoded secrets and API keys recovered from the binary
  • Client-side trust in security decisions that belong server-side
  • Insecure WebView configuration or exposed JS interfaces
  • Broken authentication or token handling in the app
What you receive

Deliverables

Everything needed to understand, prioritize and fix what we find.

  1. Component and attack-surface inventory
  2. Findings with reproduction steps and evidence
  3. Platform-specific remediation guidance for Android and iOS
  4. Backend issues identified through the app’s API usage
  5. Retest report for the remediated build

Questions

Frequently Asked Questions

Do you need the source code?

No. We perform black-box assessment from the published build, which reflects what attackers actually see. Source access can deepen the analysis when available, but it is not required.

Which platforms do you cover?

Android and iOS. Testing includes static analysis of the packaged application and dynamic analysis on a controlled device or emulator, including traffic inspection.

Is backend testing included?

We test the APIs the mobile application communicates with as part of the app’s attack surface. Broader backend or API programme work is scoped separately.
