Un cercet\u0103tor de la Universitatea Catolic\u0103 din Leuven a demonstrat la conferin\u021ba Black Hat o tehnic\u0103 de compromitere a terminalului utilizatorului Starlink, utilizat pentru conectarea abona\u021bilor la re\u021beaua de sateli\u021bi SpaceX. Terminalul este echipat cu un SoC de 64 de bi\u021bi, creat de compania STMicro special pentru SpaceX. Mediul de operare este bazat pe Linux. <\/p>\n

Metoda propus\u0103 permite executarea codului propriu pe terminalul Starlink, ob\u021binerea accesului root \u0219i accesul la re\u021beaua intern\u0103, inaccesibil\u0103 utilizatorilor prin porturile obi\u0219nuite, folosit\u0103 de terminale, de exemplu, pentru actualiz\u0103rile firmware-ului. Lucr\u0103rile publicate pot fi aplicate \u0219i pentru experimente avansate \u00een domeniul sistemelor radio definite prin software (SDR), datorit\u0103 structurii specifice a terminalului Starlink (un array de antene fazate, controlate prin program). <\/p>\n

Spargerea terminalului Starlink este interesant\u0103 din perspectiva unei atacuri asupra unui sistem Linux bine protejat, cu o implementare de calitate a modului de pornire sigur (Secure Boot). Deoarece sistemul nu a putut fi compromis prin software, spargerea a fost efectuat\u0103 la nivel hardware utiliz\u00e2nd echipamente de laborator specializate. \u00cen cele din urm\u0103, echipamentul necesar pentru spargere a fost redus la o plac\u0103 de extensie (modchip) gata f\u0103cut\u0103, folosind un microcontroler obisnuit Raspberry Pi RP2040 (Cortex M0 dual-core). <\/p>\n

Placa modchip preg\u0103tit\u0103 se conecteaz\u0103 la anumite piste ale pl\u0103cii de baz\u0103 a terminalului Starlink \u0219i provoac\u0103 o defec\u021biune prin modificarea tensiunii \u00een anumite p\u0103r\u021bi ale schemei electrice (\u201evoltage fault\u201d). Provocarea defec\u021biunii \u00een momentul verific\u0103rii semn\u0103turii digitale din ROM bootloader (BL1) permite rularea unui cod arbitrar pe SoC, indiferent de absen\u021ba unei semn\u0103turi digitale valide pentru acel cod. <\/p>\n

Schema pl\u0103cii pentru spargerea terminalelor Starlink a fost publicat\u0103 pe GitHub \u00een format KiCad. De asemenea, a fost publicat codul firmware-ului utilizat pentru atac. Costul de fabricare a pl\u0103cii este estimat la aproximativ 25 de dolari.
