Ib pab pawg kws tshawb fawb txog kev ruaj ntseg los ntawm pab pawg uCode tau tshaj tawm cov cai rau decrypting Intel microcode. Cov txheej txheem Red Unlock, tsim los ntawm tib cov kws tshawb fawb hauv xyoo 2020, tuaj yeem siv los rho tawm cov ntaub ntawv microcode. Lub peev xwm los txiav txim siab microcode tso cai rau koj los tshawb nrhiav cov qauv sab hauv ntawm microcode thiab cov txheej txheem rau kev siv x86 tshuab cov lus qhia. Tsis tas li ntawd, cov kws tshawb fawb tau rov qab kho cov qauv ntawm microcode tshiab, encryption algorithm thiab tus yuam sij siv los tiv thaiv microcode (RC4).
Txhawm rau txiav txim siab tus yuam sij encryption siv, qhov muaj qhov tsis zoo hauv Intel TXE tau siv, uas lawv tau tswj hwm kom qhib qhov tsis muaj ntaub ntawv debug hom, uas cov kws tshawb fawb tau sau npe "Liab Xauv." Hauv hom kev debug, peb tuaj yeem rub tawm cov pob tseg nrog ua haujlwm microcode ncaj qha los ntawm CPU thiab rho tawm cov algorithm thiab cov yuam sij los ntawm nws.
Cov cuab yeej tsuas tso cai rau koj kom decrypt lub microcode, tab sis tsis tso cai rau koj hloov nws, vim tias qhov kev ncaj ncees ntawm microcode ntxiv tau txheeb xyuas siv cov kos npe digital raws li RSA algorithm. Txoj kev siv tau rau Intel Gemini Lake processors raws li Goldmont Plus microarchitecture thiab Intel Apolo Lake raws li Goldmont microarchitecture.
