Kunci Private Intek BootGuard OEM Bocor dari Pencurian Siber MSI

May 10, 2023 by Coffee Bean

Intel sedang menyelidiki laporan bahwa kunci privat BootGuard, yang digunakan untuk melindungi PC dari malware tersembunyi, bocor saat data milik Micro-Star International (MSI) dicuri dan dibuang secara online.

Dapat dipahami bahwa kunci privat dibuat oleh MSI untuk digunakan dengan teknologi BootGuard Intel, dan berada di antara kode sumber internal dan materi lain yang diambil dari sistem TI pembuat suku cadang komputer bulan lalu – setidaknya beberapa di antaranya telah dibagikan di internet.

PC dengan chip Intel dan perlindungan BootGuard diaktifkan dan dikonfigurasi, biasanya dan secara umum, hanya menjalankan firmware jika ditandatangani secara digital menggunakan kunci seperti yang dibocorkan dari MSI. Firmware itu memulai OS – proses yang dijelaskan oleh Intel di sini [PDF] dan diperlukan untuk memenuhi persyaratan Windows Secure Boot.

Jika firmware tidak ditandatangani secara digital dengan benar, mungkin karena seseorang telah mencoba menumbangkan kode untuk memasukkan beberapa spyware tidak resmi di bawah sistem operasi, tidak terlihat oleh antivirus dan alat pertahanan lainnya. Idealnya, Anda ingin BootGuard mencegah firmware aneh tersebut dimulai.

Penjahat memposting tangkapan layar untuk membuktikannya, dan mengancam akan merilis data ini kecuali MSI membayar uang tebusan $4 juta. Telah dipahami setidaknya beberapa dari informasi tersebut – seperti kode sumber firmware MSI dan kunci BootGuard pribadi – telah lolos ke alam liar dari situs kebocoran pemeras.
