Badacz z Katolickiego Uniwersytetu w Leuven zaprezentowa\u0142 na konferencji Black Hat technik\u0119 kompromitacji u\u017cytkowniczego terminalu Starlink, u\u017cywanego do \u0142\u0105czenia abonent\u00f3w z orbitaln\u0105 sieci\u0105 SpaceX. Terminal jest wyposa\u017cony w w\u0142asny 64-bitowy SoC, zaprojektowany przez firm\u0119 STMicro specjalnie dla SpaceX. \u015arodowisko programowe opiera si\u0119 na systemie Linux. <\/p>\n

Proponowana metoda umo\u017cliwia uruchomienie w\u0142asnego kodu na terminalu Starlink, uzyskanie dost\u0119pu do roota oraz dost\u0119p do wewn\u0119trznej sieci, niedost\u0119pnej dla u\u017cytkownika przez standardowe porty, wykorzystywanej przez terminale, na przyk\u0142ad, do aktualizacji oprogramowania. Opublikowane zasoby mog\u0105 by\u0107 r\u00f3wnie\u017c zastosowane do zaawansowanych eksperyment\u00f3w w dziedzinie programowalnych system\u00f3w radiowych (SDR), ze wzgl\u0119du na specyficzn\u0105 struktur\u0119 terminalu Starlink (macierz anten fazowanych, zarz\u0105dzana programowo). <\/p>\n

W\u0142amanie do terminalu Starlink jest interesuj\u0105ce z punktu widzenia ataku na dobrze zabezpieczony system Linux z dobr\u0105 implementacj\u0105 trybu bezpiecznego rozruchu (Secure Boot). Poniewa\u017c systemu nie uda\u0142o si\u0119 skompromitowa\u0107 programowo, w\u0142amanie zosta\u0142o przeprowadzone na poziomie sprz\u0119towym przy u\u017cyciu specjalnego wyposa\u017cenia laboratoryjnego. Ostatecznie, potrzebne do ataku wyposa\u017cenie uda\u0142o si\u0119 zredukowa\u0107 do gotowej p\u0142ytki konwerterowej (modchip), wykorzystuj\u0105cej standardowy mikrokontroler Raspberry Pi RP2040 (dwurdzeniowy Cortex M0). <\/p>\n

Przygotowana p\u0142yta modchip jest pod\u0142\u0105czana do okre\u015blonych \u015bcie\u017cek p\u0142yty g\u0142\u00f3wnej terminala Starlink i powoduje awari\u0119 poprzez zmian\u0119 napi\u0119cia w okre\u015blonych cz\u0119\u015bciach schematu elektrycznego («voltage fault»). Wywo\u0142anie awarii w momencie sprawdzania podpisu cyfrowego w bootloaderze ROM (BL1) pozwala na uruchomienie dowolnego kodu na SoC, mimo \u017ce ten kod nie ma poprawnego podpisu cyfrowego. <\/p>\n

Schemat p\u0142ytki do w\u0142ama\u0144 do terminali Starlink zosta\u0142 opublikowany na GitHubie w formacie KiCad. Opublikowano r\u00f3wnie\u017c kod oprogramowania wykorzystanego do ataku. Koszt wytworzenia p\u0142ytki szacuje si\u0119 na oko\u0142o 25 dolar\u00f3w.
