Mumwe muongorori wekuKU Leuven akaratidza pamusangano weBlack Hat nzira yekuisa Starlink munjodzi inoshandiswa kubatanidza vanonyorera kune SpaceX satellite network. Iyo terminal ine 64-bit SoC yakagadzirwa neSTMicro zvakanangana neSpaceX. Nzvimbo yesoftware yakavakirwa pa Linux.
Iyo yakarongwa nzira inokubvumira kuti uite kodhi yako pane Starlink terminal, tora midzi yekuwana uye kuwana iyo isingasvikike kumushandisi kuburikidza neyakajairwa madoko emukati network anoshandiswa nematerminals, semuenzaniso, kugadzirisa firmware. Iro basa rakaburitswa rinogona zvakare kuiswa kune yepamusoro software-yakatsanangurwa radio (SDR) kuyedza, nekuda kweiyo chaiyo chimiro cheStarlink terminal (mutsetse wema antennas anodzorwa nesoftware).
Kubiwa kweStarlink terminal kunonakidza kubva pakuona kwekurwiswa kwechiteshi chakachengetedzwa zvakanaka Linux- sisitimu ine nzira yepamusoro yekushandisa Secure Boot mode. Sezvo sisitimu iyi isingakwanise kukanganiswa kuburikidza nesoftware, kubiwa kwacho kwakaitwa padanho rehardware uchishandisa michina yelab yakasarudzika. Pakupedzisira, hardware yaidiwa pakubiwa yakaderedzwa kuita bhodhi rekuwedzera rakagadzirwa (modchip) uchishandisa microcontroller yakajairika yeRaspberry Pi RP2040 (dual-core Cortex M0).
Iyo yakagadzirwa modchip board yakabatana kune mamwe maturu ebhodhi guru reStarlink terminal uye inokonzeresa kutadza nekushandura voltage mune zvimwe zvikamu zvemagetsi edunhu ("voltage fault"). Kukonzera kutadza panguva yekusimbisa siginecha yedhijitari muROM bootloader (BL1) inobvumira kupokana kodhi kumhanya paSoC, zvisinei nekuti iyi kodhi haina siginecha yedhijitari.
Iyo yedunhu bhodhi yekubira Starlink terminals inoburitswa paGitHub muKiCad fomati. Iyo kodhi yeiyo microcontroller firmware inoshandiswa pakurwisa yakaburitswa zvakare. Mutengo wekugadzira bhodhi unofungidzirwa kusvika pamadhora makumi maviri nemashanu.
