Para esta seção, a ferramenta [**Objection**](https://github.com/sensepost/objection) será utilizada.\
Comece obtendo uma sessão do objection executando algo como:
```bash
objection -d --gadget "iGoat-Swift" explore
objection -d --gadget "OWASP.iGoat-Swift" explore
```
```markdown
Você também pode executar `frida-ps -Uia` para verificar os processos em execução no telefone.

## Listar classes de um APP
* `ios hooking list classes`: Lista classes do aplicativo
```bash
ios hooking list classes
AAAbsintheContext
AAAbsintheSigner
AAAbsintheSignerContextCache
AAAcceptedTermsController
AAAccount
AAAccountManagementUIResponse
AAAccountManager
AAAddEmailUIRequest
AAAppleIDSettingsRequest
AAAppleTVRequest
AAAttestationSigner
[...]
```
* `ios hooking search classes <termo_de_pesquisa>`: Pesquisa uma classe que contém uma string. Você pode **pesquisar algum termo único que esteja relacionado ao nome do pacote principal do aplicativo** para encontrar as classes principais do aplicativo, como no exemplo:
```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
[...]
```
## Listar métodos de classe
* `ios hooking list class_methods`: Lista métodos de uma classe específica
```bash
ios hooking list class_methods iGoat_Swift.RCreditInfo
- cvv
- setCvv:
- setName:
- .cxx_destruct
- name
- cardNumber
- init
- initWithValue:
- setCardNumber:
```
* `ios hooking search methods <termo_de_pesquisa>`: Pesquisa um método que contém uma 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:]
```
# Hooking Básico
Agora que você **enumerou as classes e módulos** usados pelo aplicativo, você pode ter encontrado alguns **nomes de classes e métodos interessantes**.
## Hook em todos os métodos de uma classe
* `ios hooking watch class <nome_da_classe>`: Hook em todos os métodos de uma classe, despeja todos os parâmetros iniciais e retornos
```bash
ios hooking watch class iGoat_Swift.PlistStorageExerciseViewController
```
## Hook em um único método
* `ios hooking watch method "-[<nome_da_classe> <nome_do_método>]" --dump-args --dump-return --dump-backtrace`: Hook em um método específico de uma classe despejando os parâmetros, backtraces e retornos do método cada vez que é chamado
```bash
ios hooking watch method "-[iGoat_Swift.BinaryCookiesExerciseVC verifyItemPressed]" --dump-args --dump-backtrace --dump-return
```
## Alterar Retorno Booleano
* `ios hooking set return_value "-[<nome_da_classe> <nome_do_método>]" false`: Isso fará com que o método selecionado retorne o booleano indicado
```bash
ios hooking set return_value "-[iGoat_Swift.BinaryCookiesExerciseVC verifyItemPressed]" false
```
## Gerar template de hooking
* `ios hooking generate simple <nome_da_classe>`:
```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('Entrando em + sharedSchema!');
},
onLeave: function (retval) {
console.log('Saindo de + sharedSchema');
},
});
Interceptor.attach(target['+ className'].implementation, {
onEnter: function (args) {
console.log('Entrando em + className!');
},
onLeave: function (retval) {
console.log('Saindo de + className');
},
});
Interceptor.attach(target['- cvv'].implementation, {
onEnter: function (args) {
console.log('Entrando em - cvv!');
},
onLeave: function (retval) {
console.log('Saindo de - cvv');
},
});
Interceptor.attach(target['- setCvv:'].implementation, {
onEnter: function (args) {
console.log('Entrando em - setCvv:!');
},
onLeave: function (retval) {
console.log('Saindo de - setCvv:');
},
});
```
