What it detects

This rule detects bcdedit commands that disable recovery options or manipulate boot configuration to support pre-OS persistence. DragonForce abuses bcdedit as part of a UEFI bootkit workflow and to inhibit Windows recovery, ensuring the compromise survives reboot and hampering remediation.
