Expose Hidden Vulnerabilities in Your Mobile Apps
Mobile applications operate in hostile environments where attackers have full control of the device. Reverse engineering, runtime manipulation, and API interception are standard techniques — and your app needs to withstand them all. Our mobile penetration testing disassembles your Android APKs and iOS IPAs to analyze them from the inside out, testing everything from insecure local data storage to backend API vulnerabilities that are only reachable through the mobile client.
What we test
Our testers systematically evaluate every attack vector relevant to this assessment type.
Insecure Data Storage
We examine how your application stores sensitive data on-device — shared preferences, SQLite databases, plist files, Keychain/Keystore usage, application sandbox contents, backup extraction, and clipboard exposure. Sensitive data including tokens, credentials, PII, and session information must be properly encrypted and stored using platform-provided secure storage mechanisms.
Runtime Manipulation
Using Frida and Objection, we perform dynamic instrumentation to hook into your application at runtime. We bypass root/jailbreak detection, disable certificate pinning, manipulate function return values, bypass biometric authentication, tamper with in-app purchase logic, and modify security-critical client-side checks that should never be trusted without server-side validation.
API & Network Communication
We intercept all network traffic between your mobile app and backend services to test for broken authentication, insecure API endpoints, excessive data exposure, missing rate limiting, and business logic flaws. We evaluate certificate pinning implementation strength, test for downgrade attacks, and verify that sensitive data is never transmitted over unencrypted channels.
Reverse Engineering & Code Analysis
We decompile your Android APK (jadx, apktool) and disassemble your iOS IPA to analyze application logic, discover hardcoded secrets (API keys, encryption keys, backend URLs), identify hidden functionality, evaluate obfuscation effectiveness, and find client-side security controls that can be bypassed. Intellectual property exposure risk is also assessed.
Authentication & Session Management
We test your mobile authentication flow end-to-end: login mechanisms, token storage and rotation, session timeout enforcement, biometric authentication implementation, OAuth integration security, deep link authentication bypass, and multi-device session management. Weak mobile authentication is a direct path to account takeover.
Platform-Specific Security
Each mobile platform has unique security concerns. For Android: exported components (activities, broadcast receivers, content providers), intent handling, WebView JavaScript bridges, and custom permission enforcement. For iOS: URL scheme handling, universal links, App Transport Security, entitlements, and inter-process communication vulnerabilities.
Our approach
A structured methodology that ensures thorough coverage and actionable results.
Scoping & Static Analysis
We collect your APK/IPA files, define the testing scope (client-side, API, backend), and perform comprehensive static analysis. This includes decompilation, manifest/plist review, permission analysis, hardcoded secret scanning, third-party library vulnerability assessment, and binary protection evaluation (PIE, ARC, stack canaries).
Dynamic Analysis & Instrumentation
We install your application on rooted/jailbroken test devices and instrument it with Frida for runtime analysis. We map all API calls, intercept encrypted traffic by bypassing certificate pinning, trace sensitive data flows through the application, and identify runtime security controls that can be defeated through hooking.
Exploitation & Business Logic Testing
We exploit discovered vulnerabilities to demonstrate real impact — extracting stored credentials, bypassing payment flows, escalating privileges through API manipulation, accessing other users' data, and circumventing security controls. Business logic testing focuses on mobile-specific attack vectors that automated tools cannot identify.
Reporting & Developer Guidance
We deliver a report with platform-specific remediation guidance including secure storage patterns for Android Keystore and iOS Keychain, proper certificate pinning implementation, root/jailbreak detection hardening, code obfuscation recommendations, and backend API fixes needed to support a defense-in-depth mobile security architecture.
