Efildr

Efildr is a reflective EFI loader and packer that transforms standard UEFI (PE32+) applications into self-contained, encrypted, fileless-executing EFI binaries. It compresses, encrypts, and executes EFI payloads directly from RAM with zero disk footprint, providing protections and anti-analysis measures. The tool includes a builder script in Python and a loader compiled in C for x86_64 UEFI platforms.
