CustomProcessingUnit

Custom Processing Unit Custom Processing Unit은 CPU 마이크로코드를 소프트웨어 수준에서 훅hook하고, 패치하고, 추적할 수 있는 최초의 동적 분석 프레임워크입니다. 이는 Intel CPU에서 CRBUS에 접근할 수 있게 해주는 문서화되지 않은 명령어를 활용하여 동작합니다. Microrocode 디컴파일러를 사용하여 CPU가 CRBUS를 사용하는 방식을 리버스 엔지니어링했으며, 해당 상호작용을 재현함으로써 CPU를 완전히 제어할 수 있습니다. 정적 분석 프레임워크는 이 폴더의 서브트리에서...
