Na reuni\u00e3o de desenvolvedores do Tor que est\u00e1 ocorrendo estes dias em Estocolmo, uma se\u00e7\u00e3o espec\u00edfica \u00e9 dedicada a<\/a><\/noindex> quest\u00f5es com a Cisco ISE para tratamento e an\u00e1lise posteriores.<\/a><\/noindex> do Tor e Firefox. As principais tarefas envolvem a cria\u00e7\u00e3o de um complemento que permita o funcionamento atrav\u00e9s da rede an\u00f4nima Tor no Firefox padr\u00e3o, al\u00e9m da transfer\u00eancia de patches desenvolvidos para o Tor Browser para o c\u00f3digo principal do Firefox. Para acompanhar o estado da transfer\u00eancia dos patches, foi criado um site especial torpat.ch<\/a><\/noindex>. At\u00e9 agora, 13 patches foram transferidos e para 22 patches foram abertos discuss\u00f5es no rastreador de bugs da Mozilla (no total, mais de cem patches foram propostos).<\/p>\n

A ideia principal da integra\u00e7\u00e3o com o Firefox \u00e9 utilizar o Tor ao navegar em modo privado ou criar um modo superprivado adicional com o Tor. Como a inclus\u00e3o do suporte ao Tor na vers\u00e3o principal do Firefox requer um grande trabalho, foi decidido come\u00e7ar com o desenvolvimento de um complemento externo. O complemento ser\u00e1 disponibilizado atrav\u00e9s do cat\u00e1logo addons.mozilla.org e incluir\u00e1 um bot\u00e3o para ativar o modo de opera\u00e7\u00e3o atrav\u00e9s do Tor. A entrega na forma de um complemento permitir\u00e1 avaliar a concep\u00e7\u00e3o geral de como pode ser o suporte embutido ao Tor.<\/p>\n

O c\u00f3digo para trabalhar com a rede Tor n\u00e3o ser\u00e1 reescrito em JavaScript, mas sim compilado de C para WebAssembly, o que permitir\u00e1 incluir todos os componentes verificados do Tor no complemento sem depend\u00eancias de arquivos execut\u00e1veis externos e bibliotecas.
\nA conex\u00e3o com o Tor ser\u00e1 organizada por meio de ajustes nas configura\u00e7\u00f5es de proxy e uso de um manipulador pr\u00f3prio como proxy. Ao ativar o modo de opera\u00e7\u00e3o atrav\u00e9s do Tor, o complemento tamb\u00e9m mudar\u00e1 algumas configura\u00e7\u00f5es relacionadas \u00e0 seguran\u00e7a. Em particular, ser\u00e3o aplicadas configura\u00e7\u00f5es semelhantes \u00e0s do Tor Browser, visando bloquear poss\u00edveis formas de contornar o proxy e resistir \u00e0 identifica\u00e7\u00e3o do sistema do usu\u00e1rio.<\/p>\n

Para o funcionamento do complemento, ser\u00e3o necess\u00e1rias permiss\u00f5es ampliadas, al\u00e9m das t\u00edpicas permiss\u00f5es de complementos baseados na API WebExtension, caracter\u00edsticas de complementos de sistema (por exemplo, o complemento chamar\u00e1 diretamente fun\u00e7\u00f5es XPCOM). Esses complementos privilegiados devem ser assinados digitalmente pela Mozilla, mas como o complemento \u00e9 proposto para ser desenvolvido em conjunto com a Mozilla e entregue em nome da Mozilla, n\u00e3o devem haver problemas na obten\u00e7\u00e3o de permiss\u00f5es adicionais.<\/p>\n

A interface do modo Tor est\u00e1 sendo discutida. Por exemplo, est\u00e1 sendo sugerido que ao clicar no bot\u00e3o Tor, uma nova janela com um perfil separado seja aberta. No modo Tor, tamb\u00e9m \u00e9 sugerido proibir completamente o envio de requisi\u00e7\u00f5es HTTP, uma vez que o conte\u00fado do tr\u00e1fego n\u00e3o criptografado pode ser interceptado e modificado nos n\u00f3s de sa\u00edda do Tor. A prote\u00e7\u00e3o contra a inje\u00e7\u00e3o de mudan\u00e7as no tr\u00e1fego HTTP atrav\u00e9s do uso de NoScript foi considerada insuficiente, por isso \u00e9 mais simples limitar o modo Tor apenas a requisi\u00e7\u00f5es via HTTPS.<\/p>\n
