Forskeren fra Katholieke Universiteit Leuven demonstrerede p\u00e5 Black Hat-konferencen en teknik til at kompromittere Starlink-brugerterminalen, der bruges til at forbinde abonnenter til SpaceX's satellitnetv\u00e6rk. Terminalen er udstyret med en speciel 64-bit SoC, skabt af STMicro specielt til SpaceX. Softwaremilj\u00f8et er baseret p\u00e5 Linux. <\/p>\n

Den foresl\u00e5ede metode g\u00f8r det muligt at k\u00f8re sin egen kode p\u00e5 Starlink-terminalen, opn\u00e5 root-adgang og f\u00e5 adgang til et internt netv\u00e6rk, som ikke er tilg\u00e6ngeligt for brugeren via almindelige porte, og som terminaler bruger til at opdatere firmware. De offentliggjorte resultater kan ogs\u00e5 anvendes til avancerede eksperimenter inden for softwaredefinerede radiosystemer (SDR) p\u00e5 grund af den specifikke opbygning af Starlink-terminalen (et array af faseforbundne antenner, der styres softwarem\u00e6ssigt). <\/p>\n

Kompromitteringen af Starlink-terminalen er interessant set i lyset af angrebet p\u00e5 et velbeskyttet Linux-system med en kvalitetsimplementering af sikker opstart (Secure Boot). Da det ikke lykkedes at kompromittere systemet softwarem\u00e6ssigt, blev angrebet udf\u00f8rt p\u00e5 hardware-niveau med brug af specialiseret laboratorieudstyr. I sidste ende lykkedes det at reducere det n\u00f8dvendige udstyr til en f\u00e6rdigbygget modchip, der bruger en almindelig Raspberry Pi RP2040 mikrokontroller (dual-core Cortex M0). <\/p>\n

Det forberedte modchip-kort tilsluttes bestemte baner p\u00e5 hovedkortet til Starlink-terminalen og for\u00e5rsager en fejl ved at \u00e6ndre sp\u00e6ndingen i bestemte dele af det elektriske kredsl\u00f8b («voltage fault»). At for\u00e5rsage fejlen under kontrol af den digitale signatur i ROM bootloader (BL1) g\u00f8r det muligt at k\u00f8re vilk\u00e5rlig kode p\u00e5 SoC, p\u00e5 trods af at denne kode ikke har en korrekt digital signatur. <\/p>\n

Diagrammet til modchip-kortet til hacking af Starlink-terminaler er offentliggjort p\u00e5 GitHub i KiCad-format. Der er ogs\u00e5 publiceret koden til den firmware, der blev brugt til angrebet. Omkostningerne til produktionen af kortet er vurderet til cirka 25 dollars.
