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.

Use this skill when:
Do not use this skill on production devices without explicit authorization -- Objection modifies app runtime behavior and may trigger security monitoring.
pip install objectionpip install frida-toolsobjection patchipa to inject Frida gadget into IPAFor 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
# 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.
