Windows Security notification showing detection of malicious content in non-volatile memory (NVRAM) Detections are reported in Windows Security, under Protection history.įigure 1.

Detection engine, which identifies exploits and malicious behaviorsįirmware scanning is orchestrated by runtime events like suspicious driver load and through periodic system scans.

Full filesystem scanner, which analyzes content inside the firmware.

UEFI anti-rootkit, which reaches the firmware through Serial Peripheral Interface (SPI).

To detect threats, it performs dynamic analysis using multiple new solution components that include: The new UEFI scanner reads the firmware file system at runtime by interacting with the motherboard chipset. How the UEFI scanner in Microsoft Defender ATP works It integrates insights from our partner chipset manufacturers and further expands the comprehensive endpoint protection provided by Microsoft Defender ATP. The UEFI scanner is a new component of the built-in antivirus solution on Windows 10 and gives Microsoft Defender ATP the unique ability to scan inside of the firmware filesystem and perform security assessment. The new UEFI scan engine in Microsoft Defender ATP expands on these protections by making firmware scanning broadly available. Windows Defender System Guard helps defend against firmware attacks by providing guarantees for secure boot through hardware-backed security features like hypervisor-level attestation and Secure Launch, also known as Dynamic Root of Trust (DRTM), which are enabled by default in Secured-core PCs. Attackers compromise the boot flow to achieve low-level malware behavior that’s hard to detect, posing a significant risk to an organization’s security posture.

Hardware and firmware-level attacks have continued to rise in recent years, as modern security solutions made persistence and detection evasion on the operating system more difficult.

Microsoft Defender Advanced Threat Protection ( Microsoft Defender ATP) is extending its protection capabilities to the firmware level with a new Unified Extensible Firmware Interface (UEFI) scanner.
