En forskare fr\u00e5n Katolska universitetet i Leuven visade p\u00e5 Black Hat-konferensen en metod f\u00f6r att kompromettera anv\u00e4ndarterminalen Starlink, som anv\u00e4nds f\u00f6r att ansluta abonnenter till SpaceX:s satellitn\u00e4tverk. Terminalen \u00e4r utrustad med en egen 64-bitars SoC, skapad av STMicro speciellt f\u00f6r SpaceX. Programvarumilj\u00f6n baseras p\u00e5 Linux. <\/p>\n

Den f\u00f6reslagna metoden g\u00f6r det m\u00f6jligt att k\u00f6ra egen kod p\u00e5 Starlink-terminalen, f\u00e5 root-\u00e5tkomst och f\u00e5 tillg\u00e5ng till ett internt n\u00e4tverk som inte \u00e4r tillg\u00e4ngligt f\u00f6r anv\u00e4ndaren via vanliga portar, som anv\u00e4nds av terminalerna, exempelvis f\u00f6r att uppdatera firmware. De publicerade resultaten kan ocks\u00e5 till\u00e4mpas f\u00f6r avancerade experiment inom programmerbara radiokommunikationssystem (SDR), p\u00e5 grund av den specifika strukturen hos Starlink-terminalen (array av fasstyrda antenner som styrs programenligt). <\/p>\n

Hackningen av Starlink-terminalen \u00e4r intressant ur en angreppssynvinkel p\u00e5 ett v\u00e4l skyddat Linux-system med en kvalitativ implementering av s\u00e4ker startprocessen (Secure Boot). Eftersom systems\u00e4kerheten inte kunde komprometteras programvarum\u00e4ssigt, genomf\u00f6rdes hackningen p\u00e5 h\u00e5rdvaruniv\u00e5 med hj\u00e4lp av specialiserad labbutrustning. Slutligen kunde den utrustning som beh\u00f6vdes f\u00f6r hackningen reduceras till en standard modchip-platta, som anv\u00e4nder en vanlig Raspberry Pi RP2040 mikrokontroller (2-k\u00e4rnig Cortex M0). <\/p>\n

Det f\u00f6rberedda modchip-kortet kopplas till specifika banor p\u00e5 huvudkortet av Starlink och orsakar ett fel genom att \u00e4ndra sp\u00e4nningen i vissa delar av det elektriska schemat (\"voltage fault\"). Att orsaka ett fel vid kontrollen av den digitala signaturen i ROM bootloader (BL1) m\u00f6jligg\u00f6r k\u00f6rning av godtycklig kod p\u00e5 SoC, trots att detta kod inte har en giltig digital signatur. <\/p>\n

Schemat f\u00f6r modchipsplattan f\u00f6r hackning av Starlink-terminaler har publicerats p\u00e5 GitHub i KiCad-format. Koden f\u00f6r den firmware som anv\u00e4ndes f\u00f6r attacken har ocks\u00e5 publicerats. Kostnaden f\u00f6r att tillverka plattan uppskattas till ungef\u00e4r 25 dollar.
