# Clickjacking con script anti-frame

Notas de Clickjacking con script anti-frame para laboratorios de PortSwigger Web Security Academy, incluido el flujo de explotación, pruebas de payloads, validación con Burp Suite y contexto de remediación.

### Clickjacking con un script rompe-marcos

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`

#### Constatación 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 incruste 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 ser incrustada en un marco';
 }, false);
}
```

Este mecanismo detecta cuando la página está dentro de 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>
```

# Agent Instructions
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 by asking a question.

Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:

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

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.

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.
