Se ha detectado una fuga de datos DNS sobre los sitios onion abiertos en modo de navegaci\u00f3n privada en el navegador web Brave, en el cual el tr\u00e1fico se redirige a trav\u00e9s de la red Tor. Se han implementado correcciones en el c\u00f3digo base de Brave que se incluir\u00e1n pr\u00f3ximamente en la pr\u00f3xima actualizaci\u00f3n estable. <\/p>\n

La causa de la fuga fue el bloqueador de anuncios, que se sugiere desactivar al utilizar Tor. Recientemente, las redes publicitarias han estado utilizando la carga de bloques de anuncios desde subdominios nativos del sitio para evadir los bloqueadores de anuncios, creando un registro CNAME en el servidor DNS del sitio que apunta al host de la red publicitaria. As\u00ed, el c\u00f3digo publicitario se carga formalmente desde el mismo dominio original dominio<\/a>, lo que evita su bloqueo. Para detectar tales manipulaciones y determinar el host relacionado a trav\u00e9s de CNAME, los bloqueadores de anuncios realizan una resoluci\u00f3n adicional del nombre en DNS. <\/p>\n

En Brave, las solicitudes DNS normales al abrir un sitio en modo privado pasaban a trav\u00e9s de la red Tor, pero el bloqueador de anuncios resolv\u00eda CNAME a trav\u00e9s del servidor DNS principal, lo que provocaba una fuga de informaci\u00f3n sobre los sitios onion abiertos en el servidor DNS del proveedor. Cabe destacar que en Brave, el modo de navegaci\u00f3n privada basado en Tor no se presenta como una garant\u00eda de anonimato y se advierte a los usuarios en la documentaci\u00f3n que no reemplaza a Tor Browser, sino que simplemente utiliza Tor como proxy.
