A Roskomnadzor oficialmente fez altera\u00e7\u00f5es no registro unificado de sites proibidos, bloqueando o acesso ao site www.torproject.org. Todas as endere\u00e7os IPv4 e IPv6 do site principal do projeto foram inclu\u00eddos no registro, mas sites adicionais n\u00e3o relacionados \u00e0 dissemina\u00e7\u00e3o do Tor Browser, como blog.torproject.org, forum.torproject.net e gitlab.torproject.org, permanecem acess\u00edveis. O bloqueio tamb\u00e9m n\u00e3o afetou os espelhos oficiais, como tor.eff.org, gettor.torproject.org e tb-manual.torproject.org. A vers\u00e3o para a plataforma Android continua sendo distribu\u00edda atrav\u00e9s da loja Google Play. <\/p>\n
O bloqueio foi realizado com base em uma antiga decis\u00e3o do tribunal distrital de Saratov, tomada em 2017. O tribunal distrital de Saratov reconheceu como ilegal a dissemina\u00e7\u00e3o do navegador an\u00f4nimo Tor Browser no site www.torproject.org, pois com ele os usu\u00e1rios podem acessar sites que cont\u00eam informa\u00e7\u00f5es inclu\u00eddas na lista federal de materiais extremistas proibidos de serem disseminados no territ\u00f3rio da Federa\u00e7\u00e3o Russa. <\/p>\n
Assim, a decis\u00e3o do tribunal declarou que as informa\u00e7\u00f5es contidas no site www.torproject.org s\u00e3o consideradas proibidas de serem distribu\u00eddas no territ\u00f3rio da Federa\u00e7\u00e3o Russa. Esta decis\u00e3o foi registrada no cadastro de sites proibidos em 2017, mas nos \u00faltimos quatro anos a entrada foi marcada como n\u00e3o sujeita a bloqueio. Hoje o status foi alterado para \u2018acesso restrito\u2019. <\/p>\n
\u00c9 not\u00e1vel que as altera\u00e7\u00f5es para ativar o bloqueio foram feitas algumas horas ap\u00f3s a publica\u00e7\u00e3o no site do projeto Tor de um aviso sobre a situa\u00e7\u00e3o dos bloqueios na R\u00fassia, que mencionava que a situa\u00e7\u00e3o poderia rapidamente evoluir para um bloqueio em larga escala do Tor na RF e descreviam poss\u00edveis maneiras de contornar o bloqueio. A R\u00fassia ocupa o segundo lugar em n\u00famero de usu\u00e1rios do Tor (cerca de 300 mil usu\u00e1rios, o que corresponde a aproximadamente 14% de todos os usu\u00e1rios do Tor), perdendo apenas para os EUA (20,98%). <\/p>\n
Caso a rede inteira seja bloqueada, e n\u00e3o apenas o site, os usu\u00e1rios s\u00e3o aconselhados a usar n\u00f3s de ponte. O endere\u00e7o de um n\u00f3 de ponte oculto pode ser obtido no site bridges.torproject.org, enviando uma mensagem ao bot do Telegram @GetBridgesBot ou enviando um e-mail atrav\u00e9s dos servi\u00e7os Riseup ou Gmail para bridges@torproject.org com um assunto vazio e o texto \u2018get transport obfs4\u2019. Para ajudar a contornar os bloqueios na R\u00fassia, entusiastas s\u00e3o convidados a participar da cria\u00e7\u00e3o de novos n\u00f3s de ponte. Atualmente, existem cerca de 1600 desses n\u00f3s (1000 podem ser utilizados com o transporte obfs4), dos quais 400 foram adicionados no \u00faltimo m\u00eas. <\/p>\n
Adicionalmente, pode-se notar o lan\u00e7amento da distribui\u00e7\u00e3o especializada Tails 4.25 (The Amnesic Incognito Live System), baseada na base de pacotes Debian e destinada a fornecer uma sa\u00edda an\u00f4nima para a rede. A sa\u00edda an\u00f4nima no Tails \u00e9 garantida pelo sistema Tor. Todas as conex\u00f5es, exceto o tr\u00e1fego pela rede Tor, s\u00e3o bloqueadas por padr\u00e3o pelo filtro de pacotes. Para armazenar os dados do usu\u00e1rio no modo de preserva\u00e7\u00e3o entre inicializa\u00e7\u00f5es, \u00e9 utilizada a criptografia. Um arquivo ISO foi preparado para download, capaz de funcionar no modo Live, com tamanho de 1,1 GB. <\/p>\n
Na nova vers\u00e3o: <\/p>\n
Tamb\u00e9m \u00e9 relevante mencionar a vers\u00e3o de corre\u00e7\u00e3o da distribui\u00e7\u00e3o Whonix 16.0.3.7, voltada para a garantia de anonimato, seguran\u00e7a e prote\u00e7\u00e3o da informa\u00e7\u00e3o pessoal. A distribui\u00e7\u00e3o \u00e9 baseada no Debian GNU\/Linux e utiliza o Tor para garantir o anonimato. Uma caracter\u00edstica do Whonix \u00e9 a divis\u00e3o da distribui\u00e7\u00e3o em dois componentes instal\u00e1veis separadamente \u2014 Whonix-Gateway, que implementa um gateway de rede para comunica\u00e7\u00f5es an\u00f4nimas, e Whonix-Workstation, com ambiente de desktop Xfce. Ambos os componentes s\u00e3o fornecidos dentro de uma \u00fanica imagem de inicializa\u00e7\u00e3o para sistemas de virtualiza\u00e7\u00e3o. O acesso \u00e0 rede a partir do ambiente Whonix-Workstation \u00e9 feito exclusivamente atrav\u00e9s do gateway Whonix-Gateway, o que isola o ambiente de trabalho da intera\u00e7\u00e3o direta com o mundo exterior e permite o uso apenas de endere\u00e7os de rede fict\u00edcios. <\/p>\n
Essa abordagem protege o usu\u00e1rio contra a vazamento de informa\u00e7\u00f5es reais endere\u00e7os IP<\/a> em caso de uma invas\u00e3o do navegador da web e mesmo na explora\u00e7\u00e3o de uma vulnerabilidade que conceda ao atacante acesso root ao sistema. A invas\u00e3o do Whonix-Workstation permitir\u00e1 que o atacante obtenha apenas par\u00e2metros de rede fict\u00edcios, uma vez que o IP real e os par\u00e2metros DNS est\u00e3o ocultos al\u00e9m do gateway de rede, que direciona o tr\u00e1fego apenas atrav\u00e9s do Tor. Na nova vers\u00e3o, foram atualizados o Tor 0.4.6.8 e o Tor Browser 11.0.1, e uma configura\u00e7\u00e3o opcional para filtrar endere\u00e7os IP de sa\u00edda foi adicionada ao firewall do Whonix-Workstation, utilizando uma lista branca outgoing_allow_ip_list. \u0420\u043e\u0441\u043a\u043e\u043c\u043d\u0430\u0434\u0437\u043e\u0440 \u043e\u0444\u0438\u0446\u0438\u0430\u043b\u044c\u043d\u043e \u0432\u043d\u0451\u0441 \u0438\u0437\u043c\u0435\u043d\u0435\u043d\u0438\u044f \u0432 \u0435\u0434\u0438\u043d\u044b\u0439 \u0440\u0435\u0435\u0441\u0442\u0440 \u0437\u0430\u043f\u0440\u0435\u0449\u0451\u043d\u043d\u044b\u0445 \u0441\u0430\u0439\u0442\u043e\u0432, \u0431\u043b\u043e\u043a\u0438\u0440\u0443\u044e\u0449\u0438\u0435 \u0434\u043e\u0441\u0442\u0443\u043f \u043a \u0441\u0430\u0439\u0442\u0443 www.torproject.org. \u0412 \u0440\u0435\u0435\u0441\u0442\u0440 \u0432\u043d\u0435\u0441\u0435\u043d\u044b \u0432\u0441\u0435 IPv4 \u0438 IPv6 \u0430\u0434\u0440\u0435\u0441\u0430 \u043e\u0441\u043d\u043e\u0432\u043d\u043e\u0433\u043e \u0441\u0430\u0439\u0442\u0430 \u043f\u0440\u043e\u0435\u043a\u0442\u0430, \u043d\u043e \u0434\u043e\u043f\u043e\u043b\u043d\u0438\u0442\u0435\u043b\u044c\u043d\u044b\u0435 \u0441\u0430\u0439\u0442\u044b, \u043d\u0435 \u0441\u0432\u044f\u0437\u0430\u043d\u043d\u044b\u0435 \u0441 \u0440\u0430\u0441\u043f\u0440\u043e\u0441\u0442\u0440\u0430\u043d\u0435\u043d\u0438\u0435\u043c Tor Browser, \u043d\u0430\u043f\u0440\u0438\u043c\u0435\u0440, blog.torproject.org, forum.torproject.net \u0438 gitlab.torproject.org, \u043e\u0441\u0442\u0430\u044e\u0442\u0441\u044f \u0434\u043e\u0441\u0442\u0443\u043f\u043d\u044b. \u0411\u043b\u043e\u043a\u0438\u0440\u043e\u0432\u043a\u0430 \u0442\u0430\u043a\u0436\u0435 \u043d\u0435 \u043a\u043e\u0441\u043d\u0443\u043b\u0430\u0441\u044c \u043e\u0444\u0438\u0446\u0438\u0430\u043b\u044c\u043d\u044b\u0445 \u0437\u0435\u0440\u043a\u0430\u043b, \u0442\u0430\u043a\u0438\u0445 \u043a\u0430\u043a tor.eff.org, gettor.torproject.org \u0438 tb-manual.torproject.org. \u0412\u0435\u0440\u0441\u0438\u044f \u0434\u043b\u044f […]<\/p>\n","protected":false,"gt_translate_keys":[{"key":"rendered","format":"html"}]},"author":1,"featured_media":0,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[702],"tags":[],"class_list":["post-102520","post","type-post","status-publish","format-standard","hentry","category-news"],"aioseo_notices":[],"aioseo_head":"\n\t\t\n\t\n\t\n\t\n\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\n","aioseo_head_json":{"title":"\ud83e\udd47O site Tor foi oficialmente bloqueado na Federa\u00e7\u00e3o Russa.
