A comunidade Libretro, que desenvolve um emulador de consoles de jogos RetroArch<\/a><\/noindex> e uma distribui\u00e7\u00e3o para a cria\u00e7\u00e3o de consoles de jogos Lakka<\/a><\/noindex>, alertou<\/a><\/noindex> sobre a invas\u00e3o de elementos da infraestrutura do projeto e vandalismo em reposit\u00f3rios. Os invasores conseguiram acessar o servidor de constru\u00e7\u00e3o (buildbot) e os reposit\u00f3rios no GitHub.<\/p>\n

No GitHub, os invasores tiveram acesso a todos reposit\u00f3rios<\/a><\/noindex> as organiza\u00e7\u00f5es Libretro, utilizando uma conta de um dos participantes confi\u00e1veis do projeto. A atividade dos invasores se limitou ao vandalismo \u2014 eles tentaram limpar o conte\u00fado dos reposit\u00f3rios ao inserir um commit inicial vazio. Durante o ataque, todos os reposit\u00f3rios listados em tr\u00eas das nove p\u00e1ginas dos reposit\u00f3rios Libretro no Github foram limpos. Felizmente, o ato de vandalismo foi bloqueado pelos desenvolvedores antes que os atacantes chegassem ao reposit\u00f3rio chave. RetroArch<\/a><\/noindex>. <\/p>\n

No servidor de constru\u00e7\u00e3o, os atacantes danificaram os servi\u00e7os que geravam compila\u00e7\u00f5es noturnas e est\u00e1veis, al\u00e9m de serem respons\u00e1veis pela organiza\u00e7\u00e3o de jogos em rede<\/a><\/noindex> (netplay lobby). A atividade maliciosa no servidor foi limitada \u00e0 remo\u00e7\u00e3o de conte\u00fado. N\u00e3o foram registradas tentativas de substitui\u00e7\u00e3o de arquivos ou modifica\u00e7\u00f5es nas compila\u00e7\u00f5es do RetroArch e pacotes principais. No momento, o funcionamento do Core Installer, Core Updater e Netplay Lobby, bem como dos sites e servi\u00e7os relacionados a esses componentes (Update Assets, Update Overlays, Update Shaders) est\u00e1 comprometido.<\/p>\n

O principal problema enfrentado pelo projeto ap\u00f3s o incidente foi a falta de um processo automatizado de backup. O \u00faltimo backup do servidor buildbot foi feito h\u00e1 alguns meses. Os problemas foram explicados pelos desenvolvedores pela falta de recursos financeiros para um sistema automatizado de backup, devido ao or\u00e7amento limitado para a manuten\u00e7\u00e3o da infraestrutura. Os desenvolvedores pretendem n\u00e3o restaurar o servidor antigo, mas lan\u00e7ar um novo, cujo desenvolvimento estava nos planos. Nesse caso, as compila\u00e7\u00f5es para sistemas prim\u00e1rios, como Linux, Windows e Android ser\u00e3o lan\u00e7adas imediatamente, mas a recupera\u00e7\u00e3o das compila\u00e7\u00f5es para sistemas especializados, como consoles de jogos e as antigas compila\u00e7\u00f5es do MSVC, exigir\u00e1 tempo.<\/p>\n

Acredita-se que a recupera\u00e7\u00e3o do conte\u00fado dos reposit\u00f3rios limpos e a identifica\u00e7\u00e3o do atacante possam ser ajudadas pelo GitHub, para o qual foi enviado um pedido correspondente. At\u00e9 agora, sabe-se apenas que o ataque foi realizado a partir do endere\u00e7o IP 54.167.104.253, ou seja, o prov\u00e1vel atacante usou um servidor virtual comprometido na AWS como ponto intermedi\u00e1rio. N\u00e3o h\u00e1 informa\u00e7\u00f5es sobre o m\u00e9todo de invas\u00e3o fornecidas.<\/p>\n
