## What it does

The skill walks the agent through a manual iOS app audit during an authorized penetration test. Objection sits on top of Frida and ships ready-made commands, so you are not writing JavaScript for every check. Seven steps are covered: environment prep, attaching to the app, storage, network, authentication, binary protections, and platform interaction.

For storage, the skill shows how to dump keychain items, read `Info.plist`, inspect `NSUserDefaults`, and connect to the app's SQLite database. Then comes SSL pinning bypass with `ios sslpinning disable`, with traffic inspected through Burp Suite. For authentication the agent lists Objective-C classes, searches them by substrings like Auth or Token, and hooks methods to dump arguments and return values.

What you need up front: Python 3.10+ with pip, the `objection` and `frida-tools` packages, and a target iOS device — either jailbroken with Frida server running, or non-jailbroken with a repackaged IPA from `objection patchipa`. For iOS testing it suggests macOS with Xcode and ideviceinstaller. One thing to keep in mind: Objection changes app behaviour at runtime and can trip security monitoring, so it does not belong on production devices without explicit authorization. Every change is runtime-only and resets on app restart, so document findings as you go. Some apps detect Frida and crash on attach; the skill suggests hooking anti-Frida checks early via `--startup-command`.

## When to use it
- dump keychain items the app can reach
- disable SSL pinning and watch HTTPS traffic through a proxy
- find auth classes and methods by name and hook them
- check how the app detects jailbreaks
- search process memory for passwords and API keys

## Example prompts
- Set up my iOS audit environment: jailbroken device, Frida server, Objection
- Dump the keychain and NSUserDefaults for the target app and show me what is in there
- Disable SSL pinning and check whether traffic goes through Burp Suite

# 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
```
