# Clickjacking com Script Anti-Frame

Notas sobre Clickjacking com Script Anti-Frame para laboratórios da PortSwigger Web Security Academy, incluindo fluxo de exploração, teste de payloads, validação no Burp Suite e contexto de remediação.

### Clickjacking com um script anti-frame

Realize um ataque de clickjacking que altere o endereço de e-mail do usuário apesar da presença de um "anti-frame". O laboratório é resolvido quando o e-mail da conta for 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 (anti-frame)

A página contém um script que impede ser enquadrada 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 enquadrada';
 }, 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>
```

# 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/pt-br/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.
