[:pt]Segundo alguns peritos de seguran\u00e7a o Conficker vai amanh\u00e3, 1 de Abril, tentar entrar em contacto com um dos milhares de sites que supostamente lhe dar\u00e3o novas instru\u00e7\u00f5es para continuar a sua senda do mal.<\/p>\n

Uma das melhores formas de evitar que o Conficker entre em contacto com esses sites, \u00e9 evitar que o servidor DNS resolva os dom\u00ednios em quest\u00e3o, o que \u00e0 partida pode parecer uma tarefa complicada, mas n\u00e3o \u00e9.<\/p>\n

O\u00a0OpenDNS<\/a>, que \u00e9 gratuito, disponibiliza servidores DNS que n\u00e3o resolvem os endere\u00e7os pedidos pelo Conficker. Tudo o que \u00e9 necess\u00e1rio \u00e9 substituir no seu computador ou rede os servidores DNS que usa para resolu\u00e7\u00e3o de\u00a0dom\u00ednios\u00a0na Internet pelos deles. Aten\u00e7\u00e3o! N\u00e3o mudar os servidores DNS que resolvem nomes internamente!<\/span><\/p>\n

Al\u00e9m de impedir que o Conficker “telefone para casa” o OpenDNS permite-lhe ver se tem algum computador infectado na sua rede atrav\u00e9s do painel de estado que disponibiliza. Nele, podemos verificar quantos\u00a0dom\u00ednios\u00a0foram bloqueados e porque raz\u00e3o. Se tiver algum computador infectado com o Conficker certamente apareceram muitos bloqueados catalogados com “malware”.<\/p>\n

Mas nem s\u00f3 de Confickers vive o OpenDNS. As suas bases de dados cont\u00eam classifica\u00e7\u00f5es de milh\u00f5es de sites que os dividem em diversas categorias e n\u00f3s podemos optar por banir da nossa rede (ou computador). Esta potencialidade, aliada \u00e0 sua rapidez, disponibilidade e outras pequenas caracter\u00edsticas tornam o OpenDNS um servi\u00e7o essencial… e gratuito \ud83d\ude42<\/p>\n

[:en]According to some security experts, Conficker, will tomorrow, April 1, try to get in touch with one of the thousands of sites that supposedly will give it further instructions to continue his path of evil.<\/p>\n

One of the best ways to prevent Conficker coming into contact with these sites, is to prevent the DNS server from resolving \u00a0the sites in question, which may seem a complicated task, but it is not.<\/span><\/p>\n

OpenDNS,<\/a> which is free, provides DNS servers that do not resolve the addresses requested by Conficker.<\/span> All that is needed is to replace in your computer or network the DNS servers used for resolution of \u00a0Internet addresses.<\/span> Warning!<\/span> Do not change the DNS servers that resolve names internally!<\/span><\/p>\n

In addition to preventing the Conficker “phone home” the OpenDNS allows you to see if you have any infected computer on your network through a state panel that it provides.<\/span> In it, we can see how many sites were blocked and why.<\/span><\/p>\n

But OpenDNS is much more that blocing Conficker.\u00a0Its databases contain millions of sites divided into different categories that we can choose to banish from our network (or computer).<\/span>This capability, coupled with its speed, availability and other small features OpenDNS makes an essential service and free …<\/span> \ud83d\ude42<\/p>\n
