URL title: Executing custom Option ROM on D34010WYK and persisting code in UEFI Runtime Services — casualHacking
URL description: In this post we’ll explore running unsigned Option ROM code on an Intel D34010WYK NUC, solely for testing purposes. We will verify that unsigned/unverified Option ROM code is not run when UEFI Secure Boot is enabled. We will demonstrate how to persist code at runtime using UEFI Runtime Services, and use a small signalling protocol to allow an unprivileged userland process to fake the contents of UEFI variables such as the SecureBoot variable.
