Al cargar el sistema operativo Windows por red, la herramienta sustituy\u00f3 en el sistema el controlador binario httpdisk.sys e instal\u00f3 en el almac\u00e9n del sistema su propio certificado auto-firmado en las ra\u00edces de los certificados, utilizado para certificar digitalmente el controlador. 31 de 70 paquetes antivirus que verificaron el archivo httpdisk.sys emitieron advertencias sobre la presencia de malware.       <\/p>\n<p>Esta actividad fue vista como un intento potencial de promover un backdoor y gener\u00f3 dudas sobre la confianza en el proyecto abierto Ventoy. La situaci\u00f3n se complic\u00f3 debido a que el a\u00f1o pasado, tras el incidente con el backdoor en el proyecto XZ, la comunidad ya hab\u00eda prestado atenci\u00f3n a la entrega de blobs sospechosos en el \u00e1rbol de textos fuente de Ventoy.    <\/p>\n<p>Los desarrolladores de NixOS propusieron sustituir Ventoy en el repositorio nixpkgs por el fork fnr1r (como alternativa tambi\u00e9n se puede considerar glim). Los proyectos Ventoy e iVentoy son desarrollados por un mismo autor y tienen prop\u00f3sitos similares. La diferencia es que Ventoy es completamente abierto y est\u00e1 dirigido a cargar sistemas operativos desde dispositivos USB, mientras que iVentoy es solo parcialmente abierto y est\u00e1 destinado a la carga a trav\u00e9s de la red utilizando la tecnolog\u00eda PXE.       <\/p>\n<p>El autor de los proyectos Ventoy e iVentoy se uni\u00f3 a la discusi\u00f3n del problema, explicando que el c\u00f3digo del controlador httpdisk.sys es abierto, y que el propio controlador est\u00e1 destinado a montar im\u00e1genes de disco en Windows a trav\u00e9s de la red sobre el protocolo HTTP, lo que se utiliza en iVentoy para obtener los datos de instalaci\u00f3n de Windows. La sustituci\u00f3n de controladores y scripts en el sistema despu\u00e9s de la carga es un comportamiento documentado. <a class=\"wpil_keyword_link\" href=\"https:\/\/prohoster.info\/es\/server\/dts-los-angeles\/\"   title=\"servidores\" data-wpil-keyword-link=\"linked\"  data-wpil-monitor-id=\"3966\">servidores<\/a> La sustituci\u00f3n de controladores y scripts en el sistema despu\u00e9s de la carga es un comportamiento documentado.     <\/p>\n<p>El certificado propio, con el que se firm\u00f3 este controlador, se ha a\u00f1adido al almac\u00e9n de certificados ra\u00edz para permitir la carga del controlador omitiendo la verificaci\u00f3n de firma digital aplicada por el sistema de Windows. El certificado se utiliz\u00f3 solo en un entorno temporal de WinPE (Windows Preinstallation Environment), creado en la memoria RAM. No se realizaron cambios en las instalaciones fijas de Windows en el disco. Se ha declarado que en la pr\u00f3xima versi\u00f3n de iVentoy se dejar\u00e1 de usar la sustituci\u00f3n de su certificado, ya que se utilizar\u00e1 el arranque de WinPE en modo de prueba para garantizar la carga del controlador.      <\/p>\n<p>En cuanto al suministro de blobs (1, 2, 3) en Ventoy, el desarrollador ha declarado que estos archivos binarios se obtuvieron directamente de otros proyectos de c\u00f3digo abierto y que Ventoy los utiliza sin modificaciones. Los archivos ejecutables listos se utilizan en el proceso de configuraci\u00f3n de sistemas de arranque. Como alternativa, se sugiere no utilizar construcciones listas, sino compilarlas para los lanzamientos de Ventoy de forma independiente utilizando GitHub CI.<br \/>\n<br \/>Fuente: <a
