Bug no Safari possibilita roubo de arquivos em dispositivos Apple


Cansado de esperar por uma resolução da Apple, o pesquisador de segurança Pawel Wylecial decidiu divulgar um bug no navegador Safari que permite o roubo de arquivos em dispositivos macOS e iOS. Cofundador da empresa de segurança polonesa Redteam.Pl, Wylecial publicou os detalhes sobre a falha de segurança descoberta no blog de sua companhia, na última segunda-feira (24).De acordo com Wylecial, o bug reside na API Web Share do Safari — novo recurso que permite o compartilhamento de textos, links, arquivos e outros conteúdos entre navegadores. Como o Safari oferece suporte para o compartilhamento de arquivos armazenados no disco rígido do usuário (por meio do esquema file://URL), o bug pode fazer com que conteúdos privados sejam vazados em questão de segundos.Apesar de a brecha de segurança abrir margem para acessos de hackers aos arquivos por meio de páginas de web maliciosas, o pesquisador de segurança classificou o bug como uma falha "não muito séria". Wylecial lembra que o roubo de dados depende da interação do usuário e de uma engenharia para a indução de vazamentos, mas admite que é extremamente fácil para os invasores tornarem os arquivos "invisíveis", como mostra o vídeo abaixo:Apple tenta abafar o casoA divulgação do bug que possibilita o roubo de dados dos dispositivos iOS e macOS por meio do browser Safari foi divulgado no último 24, mas a Apple foi alertada por Pawel Wylecial desde abril. A gigante de Tim Cook não disponibilizou um patch para solucionar o problema e adiou a correção do bug até março de 2021 — contradizendo a própria política da empresa de divulgar falhas de segurança encontradas em até 90 dias.O problema, no entanto, parece ser recorrente e tem sido comum entre os caçadores de bugs do sistema operacional da Apple. Mesmo com um programa de recompensa para pesquisadores que encontrarem falhas em seu sistema operacional, a companhia tem demorado na resolução dos problemas, "travando" o trabalho dos pesquisadores de bugs.alexandr-bormotin-ntmu8vCwQE0-unsplash.jpgApesar de anunciar programa de recompensa para caçadores de bugs em seu sistema operacional, Apple tem demorado para divulgar e solucionar problemas. Foto: UnsplashEm abril, outro pesquisador de segurança relatou uma experiência semelhante à de Wylecial em seu Twitter. Na publicação, ele descreveu como "piada" o prazo dado pela Apple e disse que a ideia da empresa é manter os pesquisadores calados pelo maior tempo possível.I'm thinking about withdrawing from the Apple Security Bounty program.I see no evidence that Apple is serious about the program. I've heard of only 1 bounty payment, and the bug wasn't even Mac-specific.Also, Apple Product Security has ignored my last email to them for weeks.— Jeff Johnson (@lapcatsoftware) April 21, 2020Em julho, a equipe de segurança Project Zero — da Google — fez duras críticas ao Programa de Pesquisa de Segurança para Dispositivos da Apple, alegando que a companhia limita a divulgação pública das falhas encontradas e amordaça os pesquisadsores de segurança sobre suas descobertas.Contatada pela ZDNet, a Apple não quis comentar sobre o assunto.Via: ZDNet
