Ib tug kws tshawb fawb los ntawm KU Leuven tau ua qauv qhia ntawm lub rooj sib tham Black Hat ib txoj kev los cuam tshuam rau lub Starlink user terminal uas siv los txuas cov neeg rau npe rau SpaceX satellite network. Lub terminal no muaj ib lub SoC 64-bit uas tsim los ntawm STMicro tshwj xeeb rau SpaceX. Lub software ib puag ncig yog raws li Linux.
Txoj kev npaj tso cai rau koj khiav koj cov cai ntawm Starlink davhlau ya nyob twg, tau txais cov hauv paus nkag thiab nkag mus rau lub network sab hauv uas tsis tuaj yeem nkag mus rau tus neeg siv los ntawm cov chaw nres nkoj tsis tu ncua, siv los ntawm cov terminals, piv txwv li, hloov kho firmware. Cov ntawv tshaj tawm kuj tseem tuaj yeem siv rau kev sim siab hauv thaj chaw ntawm software-txhais xov tooj cua (SDR) systems, vim yog cov qauv tshwj xeeb ntawm Starlink davhlau ya nyob twg (ib qho array ntawm cov kav hlau txais xov phased tswj los ntawm software).
Qhov kev nyiag khoom ntawm Starlink terminal yog qhov nthuav los ntawm qhov pom ntawm kev tawm tsam rau qhov chaw tiv thaiv zoo Linux- ib lub tshuab uas muaj kev siv zoo ntawm Secure Boot mode. Vim tias lub tshuab tsis tuaj yeem raug cuam tshuam los ntawm software, qhov hack tau ua tiav ntawm qib kho vajtse siv cov khoom siv hauv chav kuaj tshwj xeeb. Thaum kawg, cov khoom siv uas xav tau rau qhov hack tau txo qis rau lub rooj tsavxwm ntxiv (modchip) uas npaj txhij siv tus qauv Raspberry Pi RP2040 microcontroller (dual-core Cortex M0).
Lub rooj tsavxwm modchip npaj tau txuas nrog rau qee qhov ntawm lub rooj tsav xwm tseem ceeb ntawm Starlink davhlau ya nyob twg thiab ua rau tsis ua haujlwm los ntawm kev hloov pauv qhov hluav taws xob hauv qee qhov ntawm cov hluav taws xob hluav taws xob ("voltage txhaum"). Ua rau muaj qhov tsis ua tiav thaum kuaj xyuas cov kos npe digital hauv ROM bootloader (BL1) tso cai rau kev txiav txim siab tsis raug cai ntawm SoC, txawm tias tsis muaj qhov tseeb kos npe rau cov cai no.
Daim duab kos duab rau hacking Starlink terminals yog luam tawm ntawm GitHub hauv KiCad hom. Cov cai ntawm microcontroller firmware siv rau kev tawm tsam kuj tau luam tawm. Tus nqi los tsim lub rooj tsavxwm yog kwv yees li ntawm $ 25.
