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: [e-mail]"

# 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"
