CYBERSECURITY TESTING

Mobile Application
Security Testing & Assessment.

Protect data on the device, through the API and across every trust boundary. World Computing combines static and dynamic analysis with practical abuse testing to show where an iOS or Android app could expose data or allow misuse.

WHAT IS MOBILE APP SECURITY TESTING?

More than the screen a user sees.

Security depends on local storage, operating-system protections, application code, third-party software development kits, transport security, authentication flows and the APIs behind the app. Weakness in any one of these layers can undermine the whole service.

Coverage is informed by the OWASP Mobile Application Security Verification Standard (MASVS) and Mobile Application Security Testing Guide (MASTG), adjusted for actual business risk.

When This Service Is Useful

New iOS or Android apps approaching public or enterprise release.
Apps processing personal, financial, health, location or sensitive data.
Major changes to authentication, payments, offline storage, or APIs.
White-label apps, staff apps and enterprise mobile solutions.
Responding to security disclosures, platform warnings or alerts.
Providing independent evidence for procurement and customer assurance.

COMPREHENSIVE COVERAGE

What we test.

We evaluate your mobile application package, device runtime state, and connected backend infrastructure.

SURFACE

Architecture & Attack Surface

Application components, permissions, exported interfaces, platform services, third-party SDKs, update paths and backend dependencies.

STORAGE

Local Data Storage

Databases, preferences, files, caches, logs, backups, screenshots, notifications, clipboard use and data persistence.

IDENTITY

Authentication & Sessions

NETWORK

Network Communication

Transport encryption, certificate validation, endpoint trust, proxy behaviour, and interception resilience.

CRYPTO

Cryptography & Keys

Use of platform key stores, random number generation, hard-coded secrets, and key protection mechanisms.

PLATFORM

Platform Interaction

Deep links, custom URL schemes, intents, inter-process communication, web views, and accessibility exposures.

INTEGRITY

Code Integrity & Resilience

Debugging, tampering, reverse engineering, obfuscation, root/jailbreak conditions and runtime manipulation.

LOGIC

Privacy, APIs & Logic

Permissions, tracking, excessive data collection, backend authorization, workflow abuse, and client trust.

STANDARDS

Standards-Informed

OWASP MASVS, OWASP MASTG, OWASP API Security guidance, and NCSC penetration-testing frameworks.

METHODOLOGY

How the engagement works.

A structured 6-stage testing lifecycle designed for thorough assurance without operational risk.

STAGE 01

Define Test Model

Confirm platforms, app versions, distribution method, backend scope, user roles, devices and source code availability.

STAGE 02

Prepare Builds & Access

Obtain agreed application packages, test accounts, API documentation, test data and environment requirements.

STAGE 03

Static Analysis

Review package structure, configuration, permissions, secrets, libraries and security implementation choices.

STAGE 04

Dynamic Analysis

Exercise the running application, observe local/network behavior and safely manipulate inputs and workflows.

STAGE 05

Validate Impact

Test whether weaknesses cross from the device into user accounts, APIs, data or privileged business functions.

STAGE 06

Report & Re-Test

Deliver evidence-led findings and verify remediated builds or backend changes included in the re-test.

ENGAGEMENT DETAILS

Requirements & Deliverables.

Everything needed to execute a successful mobile security assessment.

What We Need From You

The exact Android package (.apk/.aab) or iOS build (.ipa) and version.
Test accounts covering each important role and subscription level.
Backend endpoints, API documentation and test-environment details.
Supported operating-system versions and device requirements.
Source code, symbol files or architecture notes (for white-box reviews).

What You Receive

Executive summary and clear statement of assessed build and platform scope.
Mobile-specific findings with evidence from static, dynamic and network analysis.
Affected operating systems, versions, components and backend dependencies.
Risk explanation covering device, user account, backend and business impact.
Developer-focused remediation guidance mapped to root cause.
Coverage notes and re-test verification results for corrected builds.

Important Scope & Safety Note

Testing uses agreed test accounts, devices and data. We do not access other customers' information, disrupt live services or bypass platform controls outside authorised scope. Some resilience tests, such as runtime manipulation or rooted-device scenarios, are performed only where they match the threat model. The assessment is point-in-time and applies to the specified build and backend scope.

WHY WORLD COMPUTING

Clear, evidence-led mobile testing.

Evidence-Led Reporting

Clear reporting designed for both technical development teams and executive decision-makers.

Risk-Proportionate Testing

Assessments designed around your actual business risk, technology stack and operational constraints.

Actionable Remediation

Findings prioritized for remediation with practical guidance rather than alarmist language.

Developer-Collaborative

A collaborative approach that supports developers, infrastructure teams and service owners throughout.

COMMON QUESTIONS

Mobile Security FAQ

Do you test both iOS and Android?

Yes. They are treated as separate platforms because their security models, application packages and attack surfaces differ. A cross-platform app normally requires coverage of both builds.

Can you test the app-store version?

Yes, although a development or enterprise build may provide better visibility for some tests. We agree which build gives the right balance between release realism and depth of assurance.

Is the backend API included?

It can be. Mobile security is often inseparable from API security, so the scope should identify the endpoints and user roles that support the app. A large API estate may justify a separate engagement.

Do you need a rooted or jailbroken device?

Not for every assessment. Those conditions can help test resilience and local protections, but they are used only when relevant to the threat model and agreed scope.

Will you review third-party SDKs?

We identify security-relevant SDKs and how they affect permissions, data flows and attack surface. A full source-level review of every dependency requires a specifically agreed white-box scope.

When should mobile testing be repeated?

Repeat testing after material changes to authentication, local storage, cryptography, platform integrations, SDKs, backend APIs or high-risk workflows, and on a risk-based periodic schedule.
