analyzing-ios-app-security-with-objection

Performs runtime mobile security exploration of iOS applications using Objection, a Frida-powered toolkit that enables security testers to interact with app internals without jailbreaking. Use when assessing iOS app security posture, bypassing client-side protections, dumping keychain items, inspecting filesystem storage, and evaluating runtime behavior. Activates for requests involving iOS security testing, Objection runtime analysis, Frida-based iOS assessment, or mobile runtime exploration.

Analyzing iOS App Security with Objection

When to Use

Use this skill when:

Performing runtime security assessment of iOS applications during authorized penetration tests
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:

# Install Frida server on device via Cydia/Sileo
# SSH to device and start Frida server
ssh root@<device_ip> "/usr/sbin/frida-server -D"

# Verify Frida connectivity
frida-ps -U  # List processes on USB-connected device

For non-jailbroken devices (authorized testing):

# 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

# 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"

# 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

# 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

# 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

# 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/

# 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

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
