A Google apresentou o lan\u00e7amento da ferramenta Magika 1.0, destinada a determinar o tipo de conte\u00fado com base na an\u00e1lise dos dados dispon\u00edveis no arquivo. O Magika pode identificar com precis\u00e3o as linguagens de programa\u00e7\u00e3o, m\u00e9todos de compress\u00e3o, pacotes de instala\u00e7\u00e3o, c\u00f3digo execut\u00e1vel, tipos de marca\u00e7\u00e3o, formatos de \u00e1udio, v\u00eddeo, documentos e imagens utilizados no conte\u00fado. A ferramenta relacionada ao projeto e o modelo de aprendizado de m\u00e1quina est\u00e3o dispon\u00edveis sob a licen\u00e7a Apache 2.0. As liga\u00e7\u00f5es foram preparadas para as linguagens Rust, Python, JavaScript\/TypeScript e Go. <\/p>\n
Diferente de projetos semelhantes que determinam o tipo MIME com base no conte\u00fado, o Magika se destaca ao aplicar m\u00e9todos de aprendizado de m\u00e1quina, mais alto<\/a> e precis\u00e3o na identifica\u00e7\u00e3o. O modelo foi treinado usando o framework Keras com 100 milh\u00f5es de exemplos de arquivos (o tamanho do conjunto de dados \u00e9 superior a 3 TB) e suporta o reconhecimento de 200 tipos de dados com precis\u00e3o de pelo menos 99%. O modelo est\u00e1 empacotado no formato ONNX e tem apenas alguns megabytes. A utiliza\u00e7\u00e3o de m\u00e9todos de aprendizado de m\u00e1quina profundo permitiu aumentar em 50% a precis\u00e3o da determina\u00e7\u00e3o em compara\u00e7\u00e3o com o sistema anteriormente utilizado pelo Google, que era baseado em regras definidas manualmente. <\/p>\n No Google, o sistema \u00e9 utilizado para classificar arquivos nos servi\u00e7os Gmail, Drive, Code Insight e Safe Browsing durante a execu\u00e7\u00e3o de verifica\u00e7\u00f5es de seguran\u00e7a e conformidade com as regras dos servi\u00e7os. A integra\u00e7\u00e3o do Magika \u00e9 garantida nas plataformas VirusTotal e abuse.ch como um elo para a filtragem prim\u00e1ria de arquivos antes da execu\u00e7\u00e3o de analisadores espec\u00edficos. A configura\u00e7\u00e3o do Magika implantada na infraestrutura do Google permite a varredura de v\u00e1rios milh\u00f5es de arquivos por segundo e centenas de bilh\u00f5es de arquivos por semana. Ap\u00f3s o carregamento do modelo, o tempo de gera\u00e7\u00e3o de sa\u00edda \u00e9 de 5 ms ao ser testado em um \u00fanico n\u00facleo de CPU. O tempo de determina\u00e7\u00e3o quase n\u00e3o depende do tamanho do arquivo. <\/p>\n Para integrar o Magika em seus projetos, foram preparadas uma ferramenta de linha de comando, pacotes para Python, Rust e Go, al\u00e9m de uma biblioteca JavaScript que pode funcionar no navegador ou em projetos baseados em Node.js. A interface de linha de comando e a API suportam a execu\u00e7\u00e3o de opera\u00e7\u00f5es em modo batch, ou seja, permitem verificar v\u00e1rios arquivos em uma \u00fanica solicita\u00e7\u00e3o. H\u00e1 um modo de varredura recursiva em todo o conte\u00fado do diret\u00f3rio e tr\u00eas modos de previs\u00e3o para ajustar a resist\u00eancia a erros (alta confian\u00e7a, m\u00e9dia confian\u00e7a e melhor palpite). <\/p>\n Inicialmente, o projeto foi desenvolvido em Python, mas ao preparar o lan\u00e7amento da vers\u00e3o 1.0, o motor de identifica\u00e7\u00e3o de tipos de conte\u00fado foi reescrito em Rust, permitindo alcan\u00e7ar um desempenho mais alto, mantendo um n\u00edvel adequado de seguran\u00e7a no c\u00f3digo. Para a execu\u00e7\u00e3o do modelo de aprendizado de m\u00e1quina, foi utilizado o framework ONNX Runtime, e para o processamento ass\u00edncrono paralelo de solicita\u00e7\u00f5es \u2014 a biblioteca Tokio. No MacBook Pro (M4), o desempenho do motor permite processar cerca de 1000 arquivos por segundo. <\/p>\n Al\u00e9m do novo mecanismo, as mudan\u00e7as no lan\u00e7amento 1.0 incluem a amplia\u00e7\u00e3o do n\u00famero de tipos suportados de aproximadamente 100 para 200; a adi\u00e7\u00e3o de um novo cliente de linha de comando, escrito em Rust; aumento da precis\u00e3o na determina\u00e7\u00e3o de formatos de texto, como arquivos de configura\u00e7\u00e3o e c\u00f3digo; e a reestrutura\u00e7\u00e3o dos m\u00f3dulos para Python e TypeScript para facilitar sua integra\u00e7\u00e3o com outros projetos. Entre os novos tipos de conte\u00fado suportados est\u00e3o: formatos utilizados em aprendizado de m\u00e1quina e IA; linguagens de programa\u00e7\u00e3o Swift, Kotlin, TypeScript, Dart, Solidity (solidity), Web Assembly e Zig; componentes de DevOps (Dockerfiles, TOML, HashiCorp, arquivos de build Bazel e regras YARA); banco de dados SQLite; arquivos AutoCAD (dwg, dxf), Adobe Photoshop (psd) e fontes (woff, woff2). A separa\u00e7\u00e3o de c\u00f3digo em C++ e C, JavaScript e TypeScript foi aprimorada. \u041a\u043e\u043c\u043f\u0430\u043d\u0438\u044f Google \u043f\u0440\u0435\u0434\u0441\u0442\u0430\u0432\u0438\u043b\u0430 \u0440\u0435\u043b\u0438\u0437 \u0438\u043d\u0441\u0442\u0440\u0443\u043c\u0435\u043d\u0442\u0430\u0440\u0438\u044f Magika 1.0, \u043f\u0440\u0435\u0434\u043d\u0430\u0437\u043d\u0430\u0447\u0435\u043d\u043d\u043e\u0433\u043e \u0434\u043b\u044f \u043e\u043f\u0440\u0435\u0434\u0435\u043b\u0435\u043d\u0438\u044f \u0442\u0438\u043f\u0430 \u0441\u043e\u0434\u0435\u0440\u0436\u0438\u043c\u043e\u0433\u043e \u043d\u0430 \u043e\u0441\u043d\u043e\u0432\u0435 \u0430\u043d\u0430\u043b\u0438\u0437\u0430 \u0438\u043c\u0435\u044e\u0449\u0438\u0445\u0441\u044f \u0432 \u0444\u0430\u0439\u043b\u0435 \u0434\u0430\u043d\u043d\u044b\u0445.
