Proyecto Enlace Inal\u00e1mbrico Abierto<\/a><\/noindex>, dedicado al an\u00e1lisis de los protocolos inal\u00e1mbricos propietarios de Apple, present\u00f3<\/a><\/noindex> en la conferencia USENIX 2019 de Vladimir Leshchenko<\/a><\/noindex> con un an\u00e1lisis de vulnerabilidades en los protocolos inal\u00e1mbricos de Apple (se encontraron posibilidades de llevar a cabo ataques MiTM para modificar los archivos transmitidos entre dispositivos, ataques DoS para bloquear la interacci\u00f3n de dispositivos y causar el bloqueo de dispositivos, as\u00ed como el uso de AirDrop para identificar y rastrear a los usuarios). Durante la investigaci\u00f3n se prepararon implementaciones abiertas del protocolo AWDL (Apple Wireless Direct Link) y la tecnolog\u00eda AirDrop<\/a><\/noindex>, cuyas detalles fueron obtenidas mediante ingenier\u00eda inversa.<\/p>\n

La implementaci\u00f3n de AWDL est\u00e1 escrita en C y se ha publicado como una aplicaci\u00f3n de Linux owl<\/a><\/noindex> (Enlace Inal\u00e1mbrico Abierto), que utiliza la API de Netlink para realizar operaciones espec\u00edficas de Wi-Fi, como el cambio de canales. La integraci\u00f3n con la pila de red se realiza a trav\u00e9s de una interfaz de red virtual, permitiendo que aplicaciones con soporte para IPv6 utilicen el protocolo AWDL sin necesidad de modificar el c\u00f3digo. El funcionamiento es posible en tarjetas de red que soporten el modo de monitor activo, permitiendo la inyecci\u00f3n de tramas (por ejemplo, es compatible con Atheros AR9280).<\/p>\n

El protocolo AWDL es la base de las tecnolog\u00edas inal\u00e1mbricas de Apple, utilizadas para establecer interacci\u00f3n directa entre dispositivos sin necesidad de configuraci\u00f3n y emparejamiento previos. Sobre la base de AWDL funciona tambi\u00e9n el servicio AirDrop, que permite el intercambio de archivos a trav\u00e9s de Wi-Fi y Bluetooth. Los componentes de AirDrop preparados por los investigadores est\u00e1n escritos en Python y son accesibles en el marco del proyecto OpenDrop<\/a><\/noindex>. El c\u00f3digo de owl y OpenDrop se publica bajo la licencia GPLv3.<\/p>\n

OpenDrop proporciona una interfaz de l\u00ednea de comandos que permite intercambiar archivos entre dispositivos a trav\u00e9s de Wi-Fi. A nivel de protocolo, la implementaci\u00f3n es completamente compatible con los dispositivos de Apple, lo que permite establecer interacciones de sistemas basados en Linux con dispositivos con iOS y macOS. Se permite el env\u00edo de archivos solo a dispositivos Apple que se encuentren en modo de descubrimiento ilimitado por otros usuarios, ya que el descubrimiento selectivo de dispositivos y el env\u00edo a trav\u00e9s de la libreta de direcciones requieren la validaci\u00f3n de una firma digital de Apple. <\/p>\n
