Gulu la ofufuza achitetezo ochokera kugulu la uCode lasindikiza magwero a Intel microcode. Njira ya Red Unlock, yopangidwa ndi ofufuza omwewo mu 2020, itha kugwiritsidwa ntchito kuchotsa ma microcode obisika. Kuthekera komwe mukufunsidwa kumasulira ma microcode kumakupatsani mwayi wofufuza momwe ma microcode amkati amagwirira ntchito ndi njira zotsatsira malangizo a makina a x86. Kuphatikiza apo, ofufuzawo adabwezeretsanso mawonekedwe a ma microcode zosintha, ma encryption algorithm ndi kiyi yomwe imagwiritsidwa ntchito kuteteza ma microcode (RC4).
Kuti adziwe chinsinsi cha encryption chomwe chagwiritsidwa ntchito, chiwopsezo cha Intel TXE chinagwiritsidwa ntchito, chomwe adakwanitsa kuyambitsa njira yosinthira yosalembedwa, yomwe ofufuzawo adayitcha "Red Unlock." M'machitidwe owongolera, tidatha kutsitsa zotayira ndi ma microcode ogwira ntchito molunjika kuchokera ku CPU ndikuchotsa ma aligorivimu ndi makiyi momwemo.
Chida chothandizira chimangokulolani kuti musinthe ma microcode, koma sichikulolani kuti musinthe, popeza kukhulupirika kwa ma microcode kumatsimikiziridwa pogwiritsa ntchito siginecha ya digito kutengera algorithm ya RSA. Njirayi imagwira ntchito kwa ma processor a Intel Gemini Lake kutengera Microarchitecture ya Goldmont Plus ndi Intel Apolo Lake kutengera kamangidwe ka Goldmont.
