📱 Mobile Application Security

Comprehensive Mobile App Pentesting

Our mobile security testing services cover iOS and Android applications using OWASP MASVS (Mobile Application Security Verification Standard) methodology, combining static analysis, dynamic testing, reverse engineering, and runtime manipulation to identify vulnerabilities before attackers exploit them.

iOS Security Testing

• IPA Analysis: Binary decompilation using Hopper, IDA Pro, Ghidra; class-dump for Objective-C headers
• Jailbreak Detection Bypass: Runtime hooks with Frida, Cycript, objection; SSL Kill Switch 2 for cert pinning bypass
• Keychain Analysis: Sensitive data storage review, encryption validation, biometric authentication testing
• Runtime Manipulation: Method swizzling, dylib injection, Cydia Substrate hooks, cycript REPL
• WebView Security: UIWebView/WKWebView XSS, JavaScript bridge vulnerabilities, file:// protocol abuse
• Network Traffic: Burp Suite proxy configuration, mitmproxy, SSL pinning bypass (SSL Kill Switch, Objection)
• Code Signing: Entitlements review, provisioning profile analysis, signature validation bypass

Android Security Testing

• APK Reverse Engineering: APKTool, JADX, dex2jar, JD-GUI, Ghidra for native libraries (SO files)
• Root Detection Bypass: Magisk Hide, Frida scripts, Xposed Framework, runtime patching
• Insecure Storage: SharedPreferences, SQLite databases, external storage, logcat leaks
• Dynamic Analysis: Frida, objection, Drozer for IPC testing, runtime hooking with Xposed
• Native Code Analysis: ARM/ARM64 assembly, JNI vulnerabilities, buffer overflows in NDK code
• Certificate Pinning: Bypass techniques using Frida, manual patching, custom trust manager injection
• Intent Security: Exported components, intent spoofing, broadcast receiver vulnerabilities

OWASP Mobile Top 10 (2024)

M1: Improper Platform Usage - Misuse of platform features, TouchID/FaceID bypass, insecure keychain
M2: Insecure Data Storage - Sensitive data in logs, SharedPreferences, unencrypted databases
M3: Insecure Communication - Missing SSL/TLS, weak ciphers, certificate validation issues
M4: Insecure Authentication - Weak session management, biometric bypass, OAuth implementation flaws
M5: Insufficient Cryptography - Hardcoded keys, weak algorithms (DES, MD5), custom crypto
M6: Insecure Authorization - Privilege escalation, insecure direct object references (IDOR)
M7: Client Code Quality - Buffer overflows, format string vulnerabilities, memory corruption
M8: Code Tampering - Missing integrity checks, debuggable apps, runtime manipulation
M9: Reverse Engineering - Lack of obfuscation, exposed API keys, hardcoded secrets
M10: Extraneous Functionality - Debug code, test APIs, backdoors in production builds

Mobile API Security

• API Endpoint Discovery: Traffic interception, APK/IPA string extraction, endpoint enumeration
• Authentication Testing: JWT manipulation, token replay, OAuth flow testing, refresh token abuse
• Authorization Flaws: IDOR, broken object-level authorization (BOLA), mass assignment
• Rate Limiting: Brute force protection, account enumeration, SMS bombing prevention
• Business Logic: Payment flow manipulation, premium feature unlock, in-app purchase bypass
