Inspecting iOS keychain, filesystem, and memory for sensitive data exposure - Bypassing client-side security controls (SSL pinning, jailbreak detection) during security testing - Evaluating iOS app behavior at runtime without access to source code **Do not use** this skill on production devices without explicit authorization -- Objection modifies app runtime behavior and may trigger security monitoring. ## Prerequisites - Python 3.10+ with pip - Objection installed: `pip install objection` - Frida installed: `pip install frida-tools` - Target iOS device (jailbroken with Frida server, or non-jailbroken with repackaged IPA) - For non-jailbroken: `objection patchipa` to inject Frida gadget into IPA - macOS recommended for iOS testing (Xcode, ideviceinstaller) - USB connection to target device or network Frida server ## Workflow ### Step 1: Prepare the Testing Environment **For jailbroken devices:** ```bash # Install Frida server on device via Cydia/Sileo # SSH to device and start Frida server ssh root@ "/usr/sbin/frida-server -D" # Verify Frida connectivity frida-ps -U # List processes on USB-connected device ``` **For non-jailbroken devices (authorized testing):** ```bash # Patch IPA with Frida gadget objection patchipa --source target.ipa --codesign-signature "Apple Development: test@example.com" # Install patched IPA ideviceinstaller -i target-patched.ipa ``` ### Step 2: Attach Objection to Target App ```bash # Attach to running app by bundle ID objection --gadget "com.target.app" explore # Or spawn the app fresh objection --gadget "com.target.app" explore --startup-command "ios hooking list classes" ``` Once attached, Objection provides an interactive REPL for runtime exploration. ### Step 3: Assess Data Storage Security (MASVS-STORAGE) ```bash # Dump iOS Keychain items accessible to the app ios keychain dump # List files in app sandbox ios plist cat Info.plist env # Show app environment paths # Inspect NSUserDefaults for sensitive data ios nsuserdefaults get # List SQLite databases sqlite connect app_data.db sqlite execute query "SELECT * FROM credentials" # Check for sensitive data in pasteboard ios pasteboard monitor ``` ### Step 4: Evaluate Network Security (MASVS-NETWORK) ```bash # Disable SSL/TLS certificate pinning ios sslpinning disable # Verify pinning is bypassed by observing traffic in Burp Suite proxy # Monitor network-related class method calls ios hooking watch class NSURLSession ios hooking watch class NSURLConnection ``` ### Step 5: Inspect Authentication and Authorization (MASVS-AUTH) ```bash # List all Objective-C classes ios hooking list classes # Search for authentication-related classes ios hooking search classes Auth ios hooking search classes Login ios hooking search classes Token # Hook authentication methods to observe parameters ios hooking watch method "+[AuthManager validateToken:]" --dump-args --dump-return # Monitor biometric authentication calls ios hooking watch class LAContext ``` ### Step 6: Assess Binary Protections (MASVS-RESILIENCE) ```bash # Check jailbreak detection implementation ios jailbreak disable # Simulate jailbreak detection bypass ios jailbreak simulate # List loaded frameworks and libraries memory list modules # Search memory for sensitive strings memory search "password" --string memory search "api_key" --string memory search "Bearer" --string # Dump specific memory regions memory dump all dump_output/ ``` ### Step 7: Review Platform Interaction (MASVS-PLATFORM) ```bash # List URL schemes registered by the app ios info binary ios bundles list_frameworks # Hook URL scheme handlers ios hooking watch method "-[AppDelegate application:openURL:options:]" --dump-args # Monitor clipboard access ios pasteboard monitor # Check for custom keyboard restrictions ios hooking search classes UITextField ``` ## Key Concepts | Term | Definition | |------|-----------| | **Objection** | Runtime mobile exploration toolkit built on Frida that provides pre-built scripts for common security testing tasks | | **Frida Gadget** | Shared library injected into app process to enable Frida instrumentation without jailbreak | | **Keychain** | iOS secure credential storage system; Objection can dump items accessible to the target app's keychain access group | | **SSL Pinning Bypass** | Runtime modification of certificate validation logic to allow proxy interception of HTTPS traffic | | **Method Hooking** | Intercepting Objective-C/Swift method calls at runtime to observe arguments, return values, and modify behavior | ## Tools & Systems - **Objection**: High-level Frida-powered mobile security exploration toolkit with pre-built commands - **Frida**: Dynamic instrumentation framework providing JavaScript injection into native app processes - **Frida-tools**: CLI utilities for Frida including frida-ps, frida-trace, and frida-discover - **ideviceinstaller**: Cross-platform tool for installing/managing iOS apps via USB - **Burp Suite**: HTTP proxy for intercepting traffic after SSL pinning bypass ## Common Pitfalls - **App crashes on attach**: Some apps implement Frida detection. Use `--startup-command` to hook anti-Frida checks early in the app lifecycle. - **Keychain access scope**: Objection can only dump keychain items within the app's access group. System keychain items require separate jailbreak-level tools. - **Swift name mangling**: Swift method names are mangled in the runtime. Use `ios hooking list classes` with grep to find demangled names. - **Non-persistent changes**: All Objection modifications are runtime-only and reset on app restart.
