![]() This module has been tested on BIOS/UEFI/firmware updates from the following vendors. u, -unknowns When generating also print unknowns. d, -flash The input file is a flash descriptor. b, -brute The input file is a blob, search for firmware volume c, -capsule The input file is a firmware capsule, do not search. Output GUIDs for files, optionally write GUID structure file. This project will try to keep up-to-date with popular vendor GUIDs automatically. Using the -g LABEL the script will generate a Python dictionary-formatted output. There is an included script to generate additional GUID labels to import into IDA Python using Snare’s plugins. At the moment this is not-yet-scriptable. Note: when injecting into a firmware file the user will be prompted for which section to replace. f, -ff Inject payload into firmware file. c, -capsule The input file is a firmware capsule. Search a file for UEFI firmware volumes, parse and output. Usage: fv_injector.py -injection INJECTION Injection or GUID replacement (no addition/subtraction yet) can be performed on sections within a UEFI firmware file, or on UEFI firmware files within a firmware filesystem. ![]() Firmware descriptor generation using the parsed input volumes.Complete UEFI Firmware volume object hierarchy display. ![]()
