Empresa Microsoft anunciou<\/a><\/noindex> disposi\u00e7\u00e3o para pagar uma recompensa<\/a><\/noindex>, no valor de at\u00e9 cem mil d\u00f3lares, por identificar uma brecha na plataforma IoT Azure Sphere<\/a><\/noindex>, constru\u00edda<\/a><\/noindex> com base no n\u00facleo Linux e utilizando isolamento sandbox para servi\u00e7os e aplicativos principais. A recompensa \u00e9 prometida por demonstrar vulnerabilidades no subsistema Pluton<\/a><\/noindex> (raiz de confian\u00e7a implementada no chip) ou Secure World<\/a><\/noindex> (sandbox).<\/p>\n

A recompensa faz parte de um programa de pesquisa de tr\u00eas meses , que ocorrer\u00e1 de 1\u00ba de junho a 31 de agosto de 2020. A iniciativa \u00e9 especificamente voltada para o Azure Sphere OS e n\u00e3o inclui subsistemas de nuvem, que j\u00e1 fazem parte de um programa de recompensas separado. Para receber a recompensa, \u00e9 necess\u00e1rio demonstrar uma vulnerabilidade que, durante um ataque local (comprometimento do aplicativo) ou remoto, possa levar \u00e0 execu\u00e7\u00e3o de c\u00f3digo de terceiros n\u00e3o assinado digitalmente, interceptar par\u00e2metros de autentica\u00e7\u00e3o, elevar privil\u00e9gios, alterar configura\u00e7\u00f5es ou contornar restri\u00e7\u00f5es de firewall. Para conduzir a pesquisa, a Microsoft se mostrou disposta a fornecer aos participantes acesso aos produtos e servi\u00e7os, ao Azure Sphere SDK, \u00e0 documenta\u00e7\u00e3o t\u00e9cnica, al\u00e9m de garantir um canal de comunica\u00e7\u00e3o com os desenvolvedores da plataforma.<\/a><\/noindex>A plataforma Azure Sphere \u00e9 projetada para criar dispositivos de Internet das Coisas, baseados em microcontroladores (MCU, microcontroller unit) energeticamente eficientes com subsistemas perif\u00e9ricos integrados. O Azure Sphere \u00e9 utilizado, entre outras coisas, em equipamentos comerciais, como os de empresas como Starbucks. Uma das caracter\u00edsticas da plataforma \u00e9 o subsistema Pluton, destinado a fornecer recursos de hardware para criptografia, armazenamento de chaves privadas e execu\u00e7\u00e3o de opera\u00e7\u00f5es criptogr\u00e1ficas complexas. O Pluton inclui um processador especializado separado, um motor criptogr\u00e1fico, um gerador de n\u00fameros aleat\u00f3rios de hardware e um armazenamento isolado de chaves.<\/p>\n

informa\u00e7\u00f5es<\/p>\n

Adicionalmente, pode-se destacar aparecimento<\/a><\/noindex> informa\u00e7\u00f5es<\/a><\/noindex> sobre a tentativa de venda de conte\u00fados desconhecidos de reposit\u00f3rios privados do GitHub da Microsoft. Um desconhecido afirmou que conseguiu baixar cerca de 500 GB de dados de reposit\u00f3rios privados da Microsoft, hospedados no GitHub, e apresentou como prova capturas de tela e 1 GB de dados. A maioria dos participantes considerou as provas inconclusivas, pois as capturas de tela podem ser facilmente falsificadas e os dados continham um conjunto sem sentido de arquivos com texto em chin\u00eas, testes e trechos de c\u00f3digo. Um dos engenheiros da Microsoft declarou que coment\u00e1rios<\/a><\/noindex> a fuga de dados provavelmente \u00e9 uma farsa, pois a Microsoft possui uma regra que estipula que em reposit\u00f3rios privados no GitHub s\u00e3o hospedados projetos que devem se tornar p\u00fablicos dentro de 30 dias.<\/p>\n
