Un ricercatore dell'Universit\u00e0 Cattolica di Lovanio ha dimostrato alla conferenza Black Hat una tecnica per compromettere il terminale utente Starlink, utilizzato per connettere gli utenti alla rete satellitare SpaceX. Il terminale \u00e8 dotato di un proprio SoC a 64 bit, progettato da STMicro specificamente per SpaceX. L'ambiente di programmazione si basa su Linux. <\/p>\n

Il metodo proposto consente di eseguire il proprio codice sul terminale Starlink, ottenere accesso root e accedere a una rete interna non accessibile agli utenti tramite porte comuni, utilizzata dai terminali, ad esempio, per aggiornare i firmware. Le risultanze pubblicate possono anche essere applicate a esperimenti avanzati nel campo dei sistemi radio definiti da software (SDR), a causa della specifica struttura del terminale Starlink (un array di antenne a fasoe controllate in modo programmato). <\/p>\n

L'hacking del terminale Starlink \u00e8 interessante dal punto di vista di un attacco a un sistema Linux ben protetto con un\u2019ottima implementazione della modalit\u00e0 di avvio sicuro (Secure Boot). Poich\u00e9 la compromissione software non \u00e8 stata possibile, l'attacco \u00e8 stato condotto a livello hardware utilizzando attrezzature di laboratorio specializzate. Alla fine, l'attrezzatura necessaria per l'hacking \u00e8 stata ridotta a una scheda modchip pronta, che utilizza un comune microcontrollore Raspberry Pi RP2040 (Cortex M0 dual-core). <\/p>\n

La scheda modchip preparata si collega a determinate piste della scheda madre del terminale Starlink e causa un errore modificando la tensione in alcune parti del circuito elettrico (\"voltage fault\"). L'invocazione dell'errore durante la verifica della firma digitale nel bootloader ROM (BL1) consente di eseguire codice arbitrario sul SoC, nonostante l'assenza di una firma digitale corretta per quel codice. <\/p>\n

Schema della scheda per l'hacking dei terminali Starlink \u00e8 stato pubblicato su GitHub nel formato KiCad. \u00c8 stato anche pubblicato il codice del firmware utilizzato per l'attacco. Il costo di produzione della scheda \u00e8 stimato intorno ai 25 dollari.
