efivalidate (and mojo_thor)

Rick Mark has released efivalidate, a macOS-centric Ruby-based EFI checking tool. Also, by same author, Mojo_Thor project has activity. I thought it was a one-time drop, but it is actively being updated:

efivalidate is a ruby utility to take a given input EFI payload from macOS and to compare it against Apple’s validation schema. Being written in ruby this can occur off-box to ensure that the utility itself hasn’t been compromised

Loki / Thor / Mojo are a triad of Apple internal tools and malware that infects the SMC, EFI and macOS of Apple MacBooks. It is believed that direct access to the hardware is gained by re-flashing the Thunderbolt controller (via ThorUtil)
