Une fuite de DNS concernant les sites onion a \u00e9t\u00e9 identifi\u00e9e dans le navigateur web Brave, lors de l'utilisation du mode de navigation priv\u00e9e, o\u00f9 le trafic est redirig\u00e9 via le r\u00e9seau Tor. Les corrections pour r\u00e9soudre ce probl\u00e8me ont d\u00e9j\u00e0 \u00e9t\u00e9 int\u00e9gr\u00e9es \u00e0 la base de code de Brave et seront incluses dans la prochaine mise \u00e0 jour stable. <\/p>\n

La fuite a \u00e9t\u00e9 caus\u00e9e par un bloqueur de publicit\u00e9, dont il est conseill\u00e9 de d\u00e9sactiver l'utilisation lors de la navigation via Tor. Derni\u00e8rement, les r\u00e9seaux publicitaires utilisent des sous-domaines natifs du site pour contourner les bloqueurs de publicit\u00e9, ce qui n\u00e9cessite la cr\u00e9ation d'un enregistrement CNAME sur le serveur DNS du site, pointant vers l'h\u00f4te du r\u00e9seau publicitaire. De cette mani\u00e8re, le code publicitaire est formellement charg\u00e9 du m\u00eame domaine principal de domaine<\/a>, ce qui emp\u00eache son blocage. Pour d\u00e9tecter ce type de manipulation et identifier l'h\u00f4te associ\u00e9 via CNAME, les bloqueurs de publicit\u00e9 effectuent des r\u00e9solutions DNS suppl\u00e9mentaires. <\/p>\n

Dans Brave, les requ\u00eates DNS normales lors de l'ouverture d'un site en mode priv\u00e9 passaient par le r\u00e9seau Tor, mais le bloqueur de publicit\u00e9 effectuait la r\u00e9solution CNAME via le serveur DNS principal, entra\u00eenant une fuite d'informations sur les sites onion ouverts vers le serveur DNS du fournisseur. Il est \u00e0 noter que le mode de navigation priv\u00e9e bas\u00e9 sur Tor dans Brave n'est pas pr\u00e9sent\u00e9 comme garantissant l'anonymat et l'utilisateur est averti dans la documentation qu'il ne remplace pas Tor Browser, mais utilise simplement Tor en tant que proxy.
