W narz\u0119dziu iVentoy stosowanym do bootowania i instalacji r\u00f3\u017cnych system\u00f3w operacyjnych przez sie\u0107, zidentyfikowano podejrzan\u0105 aktywno\u015b\u0107. Podczas \u0142adowania systemu Windows przez sie\u0107 narz\u0119dzie to wprowadza\u0142o w system binarny sterownik httpdisk.sys i instalowa\u0142o sw\u00f3j samopodpisany certyfikat w systemowym magazynie zaufanych certyfikat\u00f3w, u\u017cywanym do podpisywania cyfrowego tego sterownika. 31 z 70 pakiet\u00f3w antywirusowych, w kt\u00f3rych sprawdzono plik httpdisk.sys, wyda\u0142o ostrze\u017cenie o obecno\u015bci z\u0142o\u015bliwego oprogramowania. <\/p>\n

Taka aktywno\u015b\u0107 zosta\u0142a odebrana jako potencjalna pr\u00f3ba wprowadzenia b\u0105d\u017a otworzy\u0142a kwesti\u0119 zaufania do otwartego projektu Ventoy. Sytuacj\u0119 pogarsza\u0142 fakt, \u017ce w ubieg\u0142ym roku, po incydencie z b\u0105d\u0105 w projekcie XZ, spo\u0142eczno\u015b\u0107 ju\u017c zwraca\u0142a uwag\u0119 na dostarczanie podejrzanych blob\u00f3w w drzewie \u017ar\u00f3d\u0142owym Ventoy. <\/p>\n

Programi\u015bci NixOS zaproponowali zast\u0105pienie Ventoy w repozytorium nixpkgs forkiem fnr1r (jako alternatywa mo\u017ce by\u0107 r\u00f3wnie\u017c rozwa\u017cany glim). Projekty Ventoy i iVentoy rozwijane s\u0105 przez jednego autora i maj\u0105 podobne przeznaczenie. R\u00f3\u017cni\u0105 si\u0119 tym, \u017ce Ventoy jest ca\u0142kowicie otwarty i przeznaczony do bootowania system\u00f3w operacyjnych z no\u015bnik\u00f3w USB, podczas gdy iVentoy jest jedynie cz\u0119\u015bciowo otwarty i s\u0142u\u017cy do bootowania przez sie\u0107 z u\u017cyciem technologii PXE. <\/p>\n

Do dyskusji na temat problemu do\u0142\u0105czy\u0142 autor projekt\u00f3w Ventoy i iVentoy, kt\u00f3ry wyja\u015bni\u0142, \u017ce kod sterownika httpdisk.sys jest otwarty, a sam sterownik s\u0142u\u017cy do montowania obraz\u00f3w dysk\u00f3w w Windows przez sie\u0107 przy u\u017cyciu protoko\u0142u HTTP, co jest u\u017cywane w iVentoy do pozyskiwania z danych instalacyjnych Windows. serwera<\/a> Podmiana sterownik\u00f3w i skrypt\u00f3w w systemie po uruchomieniu jest udokumentowanym zachowaniem. <\/p>\n

W\u0142asny certyfikat, za pomoc\u0105 kt\u00f3rego podpisano ten sterownik, zosta\u0142 dodany do magazynu g\u0142\u00f3wnych certyfikat\u00f3w, aby umo\u017cliwi\u0107 \u0142adowanie sterownika z pomini\u0119ciem weryfikacji cyfrowego podpisu stosowanej w systemach Windows. Certyfikat by\u0142 stosowany tylko w jednorazowym \u015brodowisku WinPE (Windows Preinstallation Environment), tworzonym w pami\u0119ci operacyjnej. W instalacjach Windows na dysku nie wprowadzano \u017cadnych zmian. Og\u0142oszono, \u017ce w nast\u0119pnej wersji iVentoy podmiana w\u0142asnego certyfikatu zostanie zaprzestana, poniewa\u017c do zapewnienia \u0142adowania sterownika zostanie u\u017cyty start WinPE w trybie testowym. <\/p>\n

W kwestii dostarczania blob\u00f3w (1, 2, 3) do Ventoy, tw\u00f3rca o\u015bwiadczy\u0142, \u017ce te pliki binarne s\u0105 bezpo\u015brednio pozyskiwane z innych projekt\u00f3w open source, a Ventoy wykorzystuje je bez wprowadzania zmian. Gotowe pliki wykonywalne stosowane s\u0105 w procesie konfiguracji uruchamianych system\u00f3w. Jako alternatyw\u0119 proponuje si\u0119 nie korzysta\u0107 z gotowych wydania, a samodzielnie kompilowa\u0107 je dla wyda\u0144 Ventoy za pomoc\u0105 GitHub CI.
