Mobile Application Security

Protect Your iOS and Android Applications:
MAST Security Testing

Mobile Application Security Testing (MAST)

MAST assesses your mobile applications 360° with static analysis (source code/binary), dynamic analysis (runtime) and backend API testing. We provide comprehensive testing for OWASP Mobile Top 10 vulnerabilities, insecure data storage, weak cryptography and more.

What Do We Offer? MAST Service Scope

We address mobile application security with a three-layer approach: static analysis (binary/source code), dynamic analysis (runtime) and backend API testing.

Static Analysis (SAST)

APK/IPA binary reverse engineering, decompilation, source code analysis. Detection of hardcoded secrets, insecure API keys, weak cryptography and debug flags.

Dynamic Analysis (DAST)

Runtime testing on a real device/emulator. SSL pinning bypass, root/jailbreak detection, runtime manipulation, memory dump.

Backend API Testing

Security testing of the backend APIs the mobile application communicates with. Authentication, authorization, rate limiting, injection vulnerabilities.

Data Storage Analysis

Local data storage security: SQLite, SharedPreferences, Keychain/Keystore, file system. Sensitive data stored without encryption.

Cryptography Assessment

Encryption algorithms, key management, random number generation. Detection of weak/deprecated algorithm use, hardcoded keys, IV reuse.

Network Security

TLS/SSL configuration, certificate pinning implementation, cleartext traffic, MITM attack resistance. Network security config analysis.

Android-Specific Tests

  • AndroidManifest.xml permission analysis
  • Content Provider, Broadcast Receiver, Activity export checks
  • WebView security (JavaScript injection, file access)
  • Root detection bypass and Frida/Xposed hooking
  • ProGuard/R8 obfuscation effectiveness

iOS-Specific Tests

  • Info.plist and entitlement analysis
  • Keychain data protection class checks
  • App Transport Security (ATS) configuration
  • Jailbreak detection bypass and Cycript/Frida
  • URL scheme hijacking and deep link security

Who Is It For? Target Audience

MAST is critical for any organisation publishing mobile applications.

  • Fintech and banking: Mobile banking, payment applications, crypto wallets.
  • Healthcare applications: Applications processing patient data, telemedicine platforms.
  • E-commerce: Mobile shopping applications, payment systems.
  • Enterprise applications: Employee self-service, internal applications distributed via MDM.

Why Is Mobile Security Different?

Mobile applications have a different threat model from the web: the application binary resides on the user's device and is open to reverse engineering. Trusted client fallacy: A mobile application is not a "trusted client".

How Does the Process Work? Mobile Security Pipeline

A structured process covering static analysis, dynamic testing, API security and reporting.

Scoping and Material Handover

The platform(s) to be tested, APK/IPA files or source code, and test accounts are clarified.

Static Analysis

Binary reverse engineering, source code review, manifest/config analysis, hardcoded secret scanning.

Dynamic Analysis

Runtime testing on a physical device or emulator. Traffic interception, runtime manipulation.

Backend API Testing

Security testing of the APIs the mobile application communicates with. Authentication bypass, IDOR, injection.

Reporting

A detailed report with platform-specific remediation recommendations. OWASP Mobile Top 10 mapping.

Re-test and Closure

Re-testing on the new build after fixes. Closed and remaining findings are documented.

Deliverables Platform-Specific Guidance

Platform-specific remediation recommendations enabling iOS and Android development teams to take rapid action.

Frequently Asked Questions About MAST

Do you need source code or just the APK/IPA for testing?
Both approaches are possible. With only the APK/IPA, black-box testing can be performed (via reverse engineering). If source code access is available, a more comprehensive white-box analysis is carried out. The ideal is a combination of both.
Is a jailbroken device required for iOS testing?
A jailbroken device makes dynamic analysis easier but is not mandatory. Tools such as Frida can work without jailbreak. A jailbroken device is recommended for comprehensive testing.
Can hybrid/cross-platform applications (React Native, Flutter) be tested?
Yes. Cross-platform frameworks such as React Native, Flutter, Xamarin and Cordova can be tested. Both the native layer and the JavaScript/Dart bundle are analysed separately.
How often should MAST be performed?
A comprehensive MAST is recommended before every major release and at least once a year. Re-testing should be considered after significant security changes and new platform versions.
Can an application downloaded from the store be tested?
Yes, an application downloaded from the Play Store or App Store can be tested. However, a debug build or enterprise distribution version allows more comprehensive testing.
