For this section the tool [**Objection**](https://github.com/sensepost/objection) is going to be used.\
Start by getting an objection's session executing something like:

```bash
objection -d --gadget "iGoat-Swift" explore
objection -d --gadget "OWASP.iGoat-Swift" explore
```

You can execute also `frida-ps -Uia` to check the running processes of the phone.

# Basic Enumeration of the app

## Local App Paths

*   `env`: Find the paths where the application is stored inside the device

    ```bash

## List classes of an APP

*   `ios hooking list classes`: List classes of the app

    ```bash
    ios hooking list classes

    AAAbsintheContext
    AAAbsintheSigner
    AAAbsintheSignerContextCache
    AAAcceptedTermsController
    AAAccount
    AAAccountManagementUIResponse
    AAAccountManager
    AAAddEmailUIRequest
    AAAppleIDSettingsRequest
    AAAppleTVRequest
    AAAttestationSigner
    [...]
    ```
*   `ios hooking search classes <search_term>`: Search a class that contains a string. You can **search some uniq term that is related to the main app package** name to find the main classes of the app like in the example:

    ```bash
    ios hooking search classes iGoat
    iGoat_Swift.CoreDataHelper
    iGoat_Swift.RCreditInfo
    iGoat_Swift.SideContainmentSegue
    iGoat_Swift.CenterContainmentSegue
    iGoat_Swift.KeyStorageServerSideVC
    iGoat_Swift.HintVC
    iGoat_Swift.BinaryCookiesExerciseVC
    iGoat_Swift.ExerciseDemoVC
    iGoat_Swift.PlistStorageExerciseViewController
    iGoat_Swift.CouchBaseExerciseVC
    iGoat_Swift.MemoryManagementVC
    [...]
    ```

## List class methods

*   `ios hooking list class_methods`: List methods of a specific class

    ```bash
    ios hooking list class_methods iGoat_Swift.RCreditInfo
    - cvv
    - setCvv:
    - setName:
    - .cxx_destruct
    - name
    - cardNumber
    - init
    - initWithValue:
    - setCardNumber:
    ```
*   `ios hooking search methods <search_term>`: Search a method that contains a string

    ```bash
    ios hooking search methods cvv
    [AMSFinanceVerifyPurchaseResponse + _dialogRequestForCVVFromPayload:verifyType:]
    [AMSFinanceVerifyPurchaseResponse - _handleCVVDialogResult:shouldReattempt:]
    [AMSFinanceVerifyPurchaseResponse - _runCVVRequestForCode:error:]
    [iGoat_Swift.RCreditInfo - cvv]
    [iGoat_Swift.RCreditInfo - setCvv:]
    [iGoat_Swift.RealmExerciseVC - creditCVVTextField]
    [iGoat_Swift.RealmExerciseVC - setCreditCVVTextField:]
    [iGoat_Swift.DeviceLogsExerciseVC - cvvTextField]
    [iGoat_Swift.DeviceLogsExerciseVC - setCvvTextField:]
    [iGoat_Swift.CloudMisconfigurationExerciseVC - cvvTxtField]
    [iGoat_Swift.CloudMisconfigurationExerciseVC - setCvvTxtField:]
    ```

# Basic Hooking

Now that you have **enumerated the classes and modules** used by the application you may have found some **interesting class and method names**.

## Hook all methods of a class

*   `ios hooking watch class <class_name>`: Hook all the methods of a class, dump all the initial parameters and returns

    ```bash
    ios hooking watch class iGoat_Swift.PlistStorageExerciseViewController
    ```

## Hook a single method

*   `ios hooking watch method "-[<class_name> <method_name>]" --dump-args --dump-return --dump-backtrace`: Hook an specific method of a class dumping the parameters, backtraces and returns of the method each time it's called

    ```bash
    ios hooking watch method "-[iGoat_Swift.BinaryCookiesExerciseVC verifyItemPressed]" --dump-args --dump-backtrace --dump-return
    ```

## Change Boolean Return

*   `ios hooking set return_value "-[<class_name> <method_name>]" false`: This will make the selected method return the indicated boolean

    ```bash
    ios hooking set return_value "-[iGoat_Swift.BinaryCookiesExerciseVC verifyItemPressed]" false
    ```

## Generate hooking template

*   `ios hooking generate simple <class_name>`:

    ```bash
    ios hooking generate simple iGoat_Swift.RCreditInfo

    var target = ObjC.classes.iGoat_Swift.RCreditInfo;

    Interceptor.attach(target['+ sharedSchema'].implementation, {
      onEnter: function (args) {
        console.log('Entering + sharedSchema!');
      },
      onLeave: function (retval) {
        console.log('Leaving + sharedSchema');
      },
    });


    Interceptor.attach(target['+ className'].implementation, {
      onEnter: function (args) {
        console.log('Entering + className!');
      },
      onLeave: function (retval) {
        console.log('Leaving + className');
      },
    });


    Interceptor.attach(target['- cvv'].implementation, {
      onEnter: function (args) {
        console.log('Entering - cvv!');
      },
      onLeave: function (retval) {
        console.log('Leaving - cvv');
      },
    });


    Interceptor.attach(target['- setCvv:'].implementation, {
      onEnter: function (args) {
        console.log('Entering - setCvv:!');
      },
      onLeave: function (retval) {
        console.log('Leaving - setCvv:');
      },
    });
    ```
