UEFI (Unified Extensible Firmware Interface) is the modern firmware interface that initializes hardware and launches the operating system, replacing legacy BIOS.
Overview
UEFI (Unified Extensible Firmware Interface) is the modern firmware interface that initializes hardware and launches the operating system, replacing legacy BIOS. It represents a high-value target for attackers due to its access to low-level system state and the potential for pre-boot compromise or firmware persistence. The recent article highlights a new UEFI flaw that enables early-boot DMA attacks on ASRock, ASUS, GIGABYTE, and MSI motherboards, underscoring the critical security implications of firmware-level vulnerabilities in the boot process.
