Mobile Application Security Testing Services - Android & iOS VAPT

Mobile applications handle the most sensitive user data across billions of devices globally. Yet 95% of mobile apps contain at least one critical security vulnerability that could expose customer data, financial information, or corporate secrets. Security Brigade's mobile application security testing services protect your Android and iOS applications through comprehensive penetration testing that combines automated scanning with deep manual analysis.

Our mobile app security experts have conducted over 800 mobile penetration tests across banking, healthcare, e-commerce, and enterprise applications. We identify vulnerabilities that standard security scanners miss - including business logic flaws, insecure data storage, and authentication bypasses specific to mobile platforms.

Why Mobile App Security Differs from Web Application Security

Mobile applications introduce unique attack vectors that don't exist in traditional web applications. Understanding these differences is crucial for effective security testing.

Platform-Specific Vulnerabilities

Mobile operating systems implement security models fundamentally different from web browsers. Android's permission system and iOS's sandboxing create distinct attack surfaces. A vulnerability that seems minor in web context - like insecure local storage - becomes critical when it exposes sensitive data to other apps on the device.

Our testing methodology accounts for these platform differences. We analyze how your application interacts with device hardware, operating system APIs, and third-party libraries. This includes testing camera access, location services, push notifications, and inter-app communication mechanisms.

Device-Specific Threats

Mobile devices face physical security risks that web applications never encounter. Users lose phones, share devices, and connect to untrusted networks. Our mobile application security testing evaluates how your app behaves when:

• Device storage is accessed by malicious apps
• Network traffic is intercepted on public WiFi
• Users enable accessibility services that can read screen content
• Devices are rooted or jailbroken, bypassing platform security

OWASP Mobile Top 10 - Industry-Standard Testing Framework

Security Brigade's mobile application penetration testing follows the OWASP Mobile Top 10, the globally recognized standard for mobile app security. Our testing methodology addresses each category with specific test cases developed from our 6,700+ security assessments.

Android Application Security Testing

Android's open ecosystem creates unique security challenges. Our Android security testing covers the full application lifecycle, from APK analysis to runtime manipulation. Learn more about our comprehensive Android app security testing methodology.

APK Analysis and Reverse Engineering

Every Android penetration test begins with comprehensive APK analysis. We extract and decompile your application to identify:

• Hardcoded API keys, passwords, and encryption keys
• Insecure third-party library implementations
• Hidden functionality and debug features
• Weak code obfuscation techniques
• Exported components with insufficient protection

Our analysts use advanced static analysis tools combined with manual code review to identify vulnerabilities that automated scanners miss. We examine manifest files, resource directories, and compiled bytecode to build a complete application map.

Root Detection Bypass

Many Android applications implement root detection to prevent tampering. However, poorly implemented root checks create false security confidence. Our testing evaluates:

• Multiple root detection bypass techniques
• Runtime application self-protection (RASP) effectiveness
• Anti-tampering mechanism strength
• Debug detection and prevention capabilities

We test both client-side and server-side validation mechanisms, ensuring your application maintains security even when device integrity is compromised.

Certificate Pinning Analysis

SSL certificate pinning prevents man-in-the-middle attacks by validating specific certificates or public keys. Our Android testing includes:

• Certificate pinning implementation review
• Pinning bypass attempts using Frida and Xposed
• Backup certificate validation testing
• Certificate expiration handling analysis

We identify applications vulnerable to network interception and provide specific recommendations for robust certificate pinning implementation.

Intent and IPC Security

Android's Inter-Process Communication (IPC) mechanisms create attack opportunities when incorrectly implemented. Our testing covers:

• Intent filter vulnerability analysis
• Broadcast receiver security testing
• Content provider permission validation
• Service component exposure assessment

We simulate attacks where malicious applications exploit insecure IPC to steal data or escalate privileges within your application.

iOS Application Security Testing

iOS applications benefit from Apple's strict security model, but implementation flaws still create vulnerabilities. Our iOS security testing addresses platform-specific risks through comprehensive analysis. Discover our detailed iOS app security testing approach.

• IPA extraction and analysis from jailbroken devices
• Mach-O binary examination for security flaws
• Info.plist configuration security review
• Embedded provisioning profile analysis
• Third-party framework vulnerability assessment

We use tools like class-dump, Hopper, and LLDB to analyze compiled binaries and identify security vulnerabilities in iOS applications.

Jailbreak Detection Testing

iOS jailbreak detection prevents applications from running on compromised devices. Our testing evaluates:

• File system-based jailbreak detection methods
• Dynamic library injection detection
• Debugger attachment prevention
• Runtime manipulation protection mechanisms

We attempt to bypass jailbreak detection using multiple techniques, including Substrate extensions and runtime patching, to validate protection effectiveness.

Keychain Security Analysis

iOS Keychain provides secure storage for sensitive data, but misconfigurations create vulnerabilities. Our analysis includes:

• Keychain access control list (ACL) validation
• Data protection class assessment
• Keychain sharing group security review
• Touch ID/Face ID integration analysis

We verify that sensitive data stored in Keychain maintains appropriate protection levels and access controls across application updates and device restores.
