Heart Bleed: A grande ameaça à internet

heartbleedTalvez você nunca tenha ouvido falar do Heart Bleed, a vulnerabilidade na comunicação que permite decifrar e roubar códigos e senhas criptografados e torna seus dados, seu computador, tablet e smartphone extremamente vulnerável.

Então saiba que ele andava sorrateiramente nos vazando nossos dados há uns 2 anos, mas só agora essa ameaça tornou-se pública.

A maioria dos grandes sites globais já providenciaram correções, mas isso não sgnifica que você esteja seguro.

Vai valer a pena fazer uma mudança geral de suas senhas, antes que o estrago fique maior.

Antes de mais nada, veja seu histórico de navegação nos browsers que você utiliza e verifique no site Qualys SSL Labs se eles ainda estão vulneráveis.

Mas prepare-se para ver que os grandões Facebook, Twitter, Google e dezenas de outros foram afetados, fizeram correções, mas não se divulgava o tamanho da ameaça. Ou será que ninguém conseguiu entender isso em 2 anos? 

Neste sábado, 12 de abril, das 10 às 12h (horário de Brasília), estarei debatendo na CBN Curitiba, ao vivo, esse e outros temas de segurança na web. Acompanhe em www.cbncuritiba.com.br ou FM 90.1 MHz. Participe enviando seus comentários e perguntas pelo Twitter @CBNCuritiba pelo Facebook , pelo site ou por telefone.

Veja abaixo a tabela publicada pelo Mashable (em inglês), indicando a situação dos sites mais populares e como você deve agir:

Cuidado com suas senhas!

passwordCuidado com suas senhas! O pessoal da NSA vacilou, Edward Snowden aproveitou, vazou, e o estrago causado à inteligência norte-americana e de outros países parece não ter fim.

Ex-funcionário de uma empresa contratada pela NSA Edward Snowden fez a festa e ganhou acesso a material confidencial após convencer alguns ex- colegas a compartilhar suas senhas com ele , conforme divulgou a Reuters.

O relatório, citando fontes anônimas, afirma que Snowden simplesmente pediu as senhas dos funcionários porque precisava delas para verificar falhas, como administrador da redes de computadores da NSA informado que precisava suas senhas , por conta de sua função de administrador da rede de computadores da NSA.

E o povo caiu! Entre 20 e 25 colaboradores da NSA deram suas senhas ao Snowden!

Lembrando, ele trabalhava num escritório da NSA no Havaí. Isso facilitou sua fuga para Hong Kong, depois de vazar parte das informações, de onde foi para a Rússia, onde vive como asilado político.

Será que o ambiente descontraído das ilhas havaianas deixou o pessoal da agência de inteligência mais desatentos? Quando descoberto o processo, esses funcionários que cederam as senhas foram devidamente “removidos de suas atribuições.”

O governo dos EUA aparentemente sabia que Snowden usou senhas de terceiros, e o Comitê de Inteligência do Senado aprovou recentemente um projeto de lei de financiamento atualizações de software para ajudar a evitar vazamentos futuros.

Os documentos vazados alimentaram uma série de reportagens que recvelaram o vasto alcance da arapongagem da NSA e, mais recentemente, de agências similares de outros países.

Mas e aí? Qual a implicação prática disso tudo na minha, na sua, nas nossas vidas? A qualidade de nossas senhas e sua segurança podem não ser lá essas coisas… Um estudo  da SplashData, analisado pelo portal Mashable mostra as piores senhas usadas lá pelos americanos. As que ocupam o pódio:

  1. password
  2. 123456
  3. 12345678

É bom cuidar de suas senhas, mesmo que você não trabalhe para uma agência de inteligência! Existem robôs que buscam acessos na internet usando uma lista das senhas mais óbvias. Se você usa alguma delas, você pode estar ralado!

Outra coisa, possível conselho do Snowden em seu provável futuro livro de memórias, ainda não escrito: “Nunca ceda suas senhas a terceiros, não importa a relevância da situação ou a importância da pessoa“.

Na maioria dos casos, o vazamento de dados pessoais ocorre por descuido ou negligência das pessoas. Não seja você a próxima vítima!
