<h3 id="redirection-du-trafic">Redirection du trafic</h3>
<p>Créer des règles Iptables afin de rediriger le trafic entrant vers notre interface de sortie vers internet, tout en permettant linterception du trafic entre les deux.</p>
<p>Nous activons le postrouting sur notre interface vers internet :</p>
<div class="language-plaintext highlighter-rouge"><div class="highlight"><pre class="highlight"><code>iptables -t nat -A POSTROUTING -o eth0 -j MASQUERADE
</code></pre></div></div>

iptables -A FORWARD -i wlx7cdd905f687b -o eth0 -j ACCEPT
</code></pre></div></div>
<p>Nous faisons un pré-routage des ports 80 et 443 de linterface AP vers le port découte de notre outil danalyse :</p>
<div class="language-plaintext highlighter-rouge"><div class="highlight"><pre class="highlight"><code>iptables -t nat -A PREROUTING -i wlx7cdd905f687b -p tcp --match multiport --dports 80,443 -j REDIRECT --to-port 8080
</code></pre></div></div>
<p>À partir de là tout devrait fonctionner, il nous reste à bien activer hostapd et dnsmasq :</p>
<div class="language-plaintext highlighter-rouge"><div class="highlight"><pre class="highlight"><code>systemctl start hostapd
systemctl start dnsmasq
</code></pre></div></div>
<h3 id="analyser-le-trafic">Analyser le trafic</h3>
<p>Nous allons à présent utiliser un outil pour analyser le trafic des appareils connectés sur notre point daccès, utilisation de <a href="https://mitmproxy.org/">mitmproxy</a> qui est un outil rapide à prendre en main et très complet.</p>
<p>Nous lançons donc mitmproxy en mode transparent sur le port 8080 :</p>
<div class="language-plaintext highlighter-rouge"><div class="highlight"><pre class="highlight"><code>mitmproxy mode transparent -p 8080
</code></pre></div></div>
<p>En connectant notre appareil on verra les flux http passer dans mitmproxy. Pour le https il faut installer le certificat de mitmproxy sur notre système en allant sur http://mitm.it.</p>
<h3 id="aller-plus-loin">Aller plus loin</h3>
<p>Ce qui est vraiment intéressant dans lanalyse du trafic dun téléphone sous android par exemple cest le trafic des applications installées sur lappareil. <br />
En modifiant nos règles de routage pour rediriger tout le trafic vers notre outil danalyse (et plus seulement http et https) il est possible de regarder ce que font nos applications quand on les lance.<br />
Il faut ajouter le certificat (celui généré par mitmproxy) dans le magasin de certificats du téléphone, ce qui nécessite quelques manipulations (uniquement avec un téléphone rooté).</p>
<p>Android enregistre chaque certificat sous un nom contenant le hash de ce dernier suivi de .0, nous allons donc récupérer ce hash grâce à openssl :</p>
<div class="language-plaintext highlighter-rouge"><div class="highlight"><pre class="highlight"><code>openssl x509 -subject_hash_old -in mitmproxy-ca-cert.pem | head -1
</code></pre></div></div>
<p>Et nous copions donc notre certificat sur notre téléphone (sur la carte SD par exemple) sous le nom c8750f0d.0 dans mon cas. Maintenant il nous faut ajouter ce fichier dans le bon dossier pour que notre système le prenne en compte. <br />
Ouvrir un shell root sur notre téléphone (via ADB ou directement sur lappareil) et remonter notre système en read-write (il est en read-only par défaut) :</p>
<div class="language-plaintext highlighter-rouge"><div class="highlight"><pre class="highlight"><code>su
mount -o remount,rw /system
</code></pre></div></div>
<p>Puis nous allons copier notre certificat dans le magasin du téléphone :</p>
<div class="language-plaintext highlighter-rouge"><div class="highlight"><pre class="highlight"><code>cp /emplacement/du/certificat/c8750f0d.0 /system/etc/security/cacerts/
</code></pre></div></div>
<p>On lui donne les permissions :</p>
<div class="language-plaintext highlighter-rouge"><div class="highlight"><pre class="highlight"><code>chmod 644 /system/etc/security/cacerts/c8750f0d.0
</code></pre></div></div>
<p>On remonte notre système en read-only :</p>
<div class="language-plaintext highlighter-rouge"><div class="highlight"><pre class="highlight"><code>mount -o remount,ro /system
</code></pre></div></div>
<p>Il peut être nécessaire de redemarrer le téléphone afin que le certificat soit pris en compte.</p>
<h3 id="conclusion">Conclusion</h3>
<p>Cest fini, on peut maintenant tranquillement lancer nos applications et regarder chez qui elles vont converser. Cependant lanalyse du trafic des applications sur mobile reste un sujet très complexe car nombre dapplications sur notre téléphone risquent de générer du « bruit » durant notre analyse. Vous pouvez regarder le travail d<a href="https://exodus-privacy.eu.org/fr/">Exodus Privacy</a> sur le sujet.</p>
