Un investigador de la Universidad Cat\u00f3lica de Lovaina demostr\u00f3 en la conferencia Black Hat una t\u00e9cnica para comprometer el terminal de usuario Starlink, utilizado para conectar suscriptores a la red satelital de SpaceX. El terminal cuenta con un SoC de 64 bits desarrollado por STMicro espec\u00edficamente para SpaceX. El entorno de programaci\u00f3n se basa en Linux. <\/p>\n

El m\u00e9todo propuesto permite ejecutar su c\u00f3digo en el terminal Starlink, obtener acceso root y acceso a una red interna inaccesible para el usuario a trav\u00e9s de puertos est\u00e1ndar, que es utilizada por los terminales, por ejemplo, para actualizar firmware. Los hallazgos publicados tambi\u00e9n pueden ser aplicados para experimentos avanzados en sistemas de radio definidos por software (SDR), debido a la estructura espec\u00edfica del terminal Starlink (una matriz de antenas en fase, controladas por software). <\/p>\n

La pirater\u00eda del terminal Starlink es interesante desde la perspectiva de un ataque a un sistema Linux bien protegido con una s\u00f3lida implementaci\u00f3n del modo de arranque seguro (Secure Boot). Dado que no se pudo comprometer el sistema a trav\u00e9s de software, el ataque se llev\u00f3 a cabo a nivel de hardware utilizando un equipo de laboratorio especializado. Al final, el equipo necesario para la pirater\u00eda se redujo a una placa de modificaci\u00f3n (modchip) lista que utiliza un microcontrolador Raspberry Pi RP2040 (Cortex M0 de 2 n\u00facleos). <\/p>\n

La placa modchip preparada se conecta a ciertas pistas de la placa base del terminal Starlink y provoca un fallo al alterar el voltaje en partes espec\u00edficas del esquema el\u00e9ctrico (\"fallo de voltaje\"). Provocar el fallo en el momento de verificar la firma digital en el bootloader ROM (BL1) permite ejecutar c\u00f3digo arbitrario en el SoC, a pesar de la falta de una firma digital v\u00e1lida para dicho c\u00f3digo. <\/p>\n

El esquema de la placa para hackear terminales Starlink ha sido publicado en GitHub en formato KiCad. Tambi\u00e9n se ha publicado el c\u00f3digo del firmware utilizado para el ataque. El costo de fabricaci\u00f3n de la placa se estima en aproximadamente 25 d\u00f3lares.
