# iOS Pentesting Environment Setup

### Apple Developer Program

* **Provisioning Identity**: Requires a **$99/year** **Apple Developer Program** subscription to obtain a provisioning identity for signing apps. Necessary to run apps from source code on physical devices.
* **Free Provisioning Profile (Xcode 7.2+)**:
  * Create a free iOS development provisioning profile in Xcode:
    1. Go to Xcode → Preferences → Accounts → Add Apple ID → Manage Certificates → Add Apple Development certificate.
    2. Trust the computer on the iPhone, then trust the untrusted profile in Settings → General → Profiles and Device Management.
  * Allows testing on a real iPhone without jailbreaking.
* **Resource Sharing**: Apps signed with the same certificate can securely share resources (e.g., keychain items).
* **Storage Location**: Provisioning profiles are stored in `/Library/MobileDevice/ProvisioningProfiles` on the device.

### Simulator

* **Simulator vs. Emulator**: Simulators mimic device behavior but do not replicate exact hardware functionality, limiting pentesting capabilities compared to jailbroken devices.
* **Requirements**: Xcode is the primary tool for creating, debugging, and instrumenting iOS apps. Only officially supported on macOS.
  * Download Xcode from the official App Store to avoid malware risks.
  * Xcode includes simulators and SDKs for building and testing apps.
* **Simulator Files**: Located in `/Users/<username>/Library/Developer/CoreSimulator/Devices`.
* **Accessing Simulator**:
  * Open Xcode → Xcode tab → Open Developer Tools → Simulator.
  * Select different devices (e.g., iPod touch, iPhone) from the simulator interface.
* **Application Files in Simulator**:
  * Find installed simulators in `/Users/<username>/Library/Developer/CoreSimulator/Devices`.
  * Identify the correct simulator UID by running:

    ```bash
    xcrun simctl list | grep Booted
    ```

    Example output: `iPhone 8 (BF5DA4F8-6BBE-4EA0-BA16-7E3AFD16C06C) (Booted)`.
  * App data is located in `/Users/<username>/Library/Developer/CoreSimulator/Devices/{UID}/data/Containers/Data/Application`.
  * App package is found in `/Users/<username>/Library/Developer/Xcode/DerivedData/{Application}/Build/Products/Debug-iphonesimulator/`.

### Emulator

* **Corellium**: The only publicly available iOS emulator. Enterprise SaaS solution with per-user licensing; no trial available.

### Jailbreaking

* **Overview**: Bypasses Apple’s code-signing restrictions to run unsigned code, disabling integrity checks.
* **Android vs. iOS**:
  * Android rooting may involve `su` binary or custom ROMs, sometimes without exploits if the bootloader is unlocked.
  * iOS jailbreaking requires exploits to bypass code-signing protections; custom ROMs are not possible due to bootloader restrictions.
* **Challenges**:
  * Apple patches vulnerabilities quickly, making jailbreaking difficult.
  * Downgrading iOS is limited by signing windows (SHSH blobs). Check current signing windows at [IPSW Downloads](https://ipsw.me/).
  * Avoid updating devices used for testing unless re-jailbreaking is guaranteed.
* **Jailbreak Types**:
  * **Tethered**: Requires a computer for each reboot.
  * **Semi-tethered**: Boots in non-jailbroken mode without a computer.
  * **Semi-untethered**: Requires manual re-jailbreaking without a computer.
  * **Untethered**: Permanent jailbreak without re-application.
* **Tools and Resources**:
  * Tools: Checkra1n (A7-A11 chips), Palera1n (A8-A11, iOS 15.0-16.5), Unc0ver (up to iOS 14.8).
  * Resources: [Can I Jailbreak?](https://canijailbreak.com/), [The iPhone Wiki](https://www.theiphonewiki.com/), [Reddit Jailbreak](https://www.reddit.com/r/jailbreak/).
  * Caution: Jailbreaking carries risks of instability and security vulnerabilities.

### Jailbreaking Benefits and Risks

* **Benefits**:
  * Removes sandboxing, granting apps full filesystem access.
  * Allows installation of unapproved apps and access to additional APIs.
* **Risks**:
  * Not recommended for regular users due to security risks and potential device instability.

### Post-Jailbreaking

* **Jailbreak Detection**:
  * Apps may detect jailbroken devices and refuse to run.
  * Indicators of jailbreaking:
    * Presence of jailbreak-related files/folders.
    * Read/write access outside the sandbox.
    * Altered API call behavior.
    * OpenSSH service presence.
    * `/bin/sh` returns 1 instead of 0.
  * More details: [OWASP MASTG Jailbreak Detection](https://mas.owasp.org/MASTG/iOS/0x06b-iOS-Security-Testing/).
* **Bypassing Jailbreak Detection**:
  * Use `objection` command: `ios jailbreak disable`.
  * Install [Liberty Lite](https://ryleyangus.com/repo/) via the repo’s Search tab.
