Microsoft Defender has been a Windows-cenric AV tool. Recently, Microsoft has ported it to Android and Linux. Recently, Microsoft also started adding UEFI scanning to Defender. So maybe now Android and Linux users can use Defender to scan for UEFI vulns?
CHIPSEC has been the main option for UEFI scanning. It works only on Intel systems. It works as an OS-level app (“OS-present”) on Mac, Windows, and Linux. And runs on UEFI. The OS-level scanners from Apple and Microsoft now both cover UEFI. Will either scan non-Intel systems: ARM64 and AMD64?
