Compania Google a lansat versiunea 1.0 a instrumentului Magika, destinat identific\u0103rii tipului de con\u021binut pe baza analizei datelor disponibile \u00een fi\u0219ier. Magika poate identifica cu precizie limbajele de programare utilizate \u00een con\u021binut, metodele de compresie, pachetele de instalare, codul executabil, tipurile de markup, formatele audio, video, documente \u0219i imagini. Instrumentul asociat proiectului \u0219i modelul de \u00eenv\u0103\u021bare automat\u0103 sunt distribuite sub licen\u021ba Apache 2.0. Interfe\u021bele sunt preg\u0103tite pentru limbajele Rust, Python, JavaScript\/TypeScript \u0219i Go. <\/p>\n
Spre deosebire de proiectele similare care determin\u0103 tipul MIME \u00een func\u021bie de con\u021binut, Magika se distinge prin aplicarea metodelor de \u00eenv\u0103\u021bare automat\u0103, ridicate<\/a> \u0219i prin precizia determin\u0103rii. Modelul a fost antrenat utiliz\u00e2nd cadrul Keras pe 100 de milioane de exemple de fi\u0219iere (dimensiunea setului de date dep\u0103\u0219e\u0219te 3 TB) \u0219i suport\u0103 recunoa\u0219terea a 200 de tipuri de date cu o precizie de cel pu\u021bin 99%. Modelul este compus \u00een format ONNX \u0219i are o dimensiune de doar c\u00e2\u021biva megabai\u021bi. Utilizarea metodologiilor de \u00eenv\u0103\u021bare profund\u0103 a permis o cre\u0219tere cu 50% a preciziei determin\u0103rii comparativ cu sistemul anterior utilizat de Google bazat pe reguli definite manual. <\/p>\n \u00cen Google, sistemul este utilizat pentru clasificarea fi\u0219ierelor \u00een serviciile Gmail, Drive, Code Insight \u0219i Safe Browsing \u00een timpul efectu\u0103rii verific\u0103rilor de securitate \u0219i conformitate cu regulile serviciilor. Integrarea Magika \u00een platformele VirusTotal \u0219i abuse.ch asigur\u0103 un link pentru filtrarea ini\u021bial\u0103 a fi\u0219ierelor \u00eenainte de a fi efectuate analize specifice. Configura\u021bia Magika desf\u0103\u0219urat\u0103 \u00een infrastructura Google asigur\u0103 scanarea a sute de milioane de fi\u0219iere pe secund\u0103 \u0219i a zeci de miliarde de fi\u0219iere pe s\u0103pt\u0103m\u00e2n\u0103. Dup\u0103 \u00eenc\u0103rcarea modelului, timpul de generare a rezultatului este de 5 ms \u00een testarea pe un singur nucleu CPU. Timpul de determinare este aproape independent de dimensiunea fi\u0219ierului. <\/p>\n Pentru a integra Magika \u00een proiectele tale, a fost preg\u0103tit\u0103 o utilitate \u00een linia de comand\u0103, pachete pentru Python, Rust \u0219i Go, precum \u0219i o bibliotec\u0103 JavaScript capabil\u0103 s\u0103 func\u021bioneze \u00een browser sau \u00een proiecte bazate pe Node.js. Interfa\u021ba \u00een linia de comand\u0103 \u0219i API-ul suport\u0103 execu\u021bia opera\u021biunilor \u00een modul batch, adic\u0103 permit verificarea mai multor fi\u0219iere dintr-o singur\u0103 solicitare. Exist\u0103 un mod de scanare recursiv\u0103 a \u00eentregului con\u021binut al directorului \u0219i trei moduri de previzionare pentru a adapta rezisten\u021ba la erori (\u00eenalt\u0103 \u00eencredere, medie \u00eencredere \u0219i cea mai bun\u0103 ghicire). <\/p>\n \u00centr-un prim stadiu, proiectul a fost dezvoltat \u00een Python, dar, \u00een preg\u0103tirea versiunii 1.0, motorul pentru determinarea tipurilor de con\u021binut a fost rescris \u00een Rust, ceea ce a permis ob\u021binerea unei performan\u021be mai mari, men\u021bin\u00e2nd totodat\u0103 un nivel adecvat de securitate a codului. Pentru implementarea modelului de \u00eenv\u0103\u021bare automat\u0103 s-a utilizat cadrul ONNX Runtime, iar pentru procesarea asincron\u0103 \u0219i paralel\u0103 a cererilor \u2014 biblioteca Tokio. Pe MacBook Pro (M4), performan\u021ba motorului permite procesarea a aproximativ 1000 de fi\u0219iere pe secund\u0103. <\/p>\n Pe l\u00e2ng\u0103 noul motor, schimb\u0103rile din versiunea 1.0 includ extinderea num\u0103rului de tipuri suportate de la aproximativ 100 la 200; ad\u0103ugarea unui nou client \u00een linia de comand\u0103, scris \u00een Rust; cre\u0219terea preciziei \u00een determinarea formatelor de text, cum ar fi fi\u0219ierele de configurare \u0219i codul; refacerea modulelor pentru Python \u0219i TypeScript pentru a le facilita integrarea cu alte proiecte. Printre noile tipuri de con\u021binut suportate se num\u0103r\u0103: formate utilizate \u00een \u00eenv\u0103\u021barea automat\u0103 \u0219i AI; limbaje de programare Swift, Kotlin, TypeScript, Dart, Solidity (solidity), Web Assembly \u0219i Zig; componente DevOps (Dockerfiles, TOML, HashiCorp, fi\u0219iere de compilare Bazel \u0219i reguli YARA); baze de date SQLite; fi\u0219iere AutoCAD (dwg, dxf), Adobe Photoshop (psd) \u0219i fonturi (woff, woff2).
