What is UEFI firmware settings?
Unified Extensible Firmware Interface (UEFI) is a specification for a software program that connects a computer’s firmware to its operating system (OS). UEFI is expected to eventually replace basic input/output system (BIOS) but is compatible with it.
Where is UEFI firmware stored?
/EFI/ directory
UEFI is a mini-operating system that sits on top of a computer’s hardware and firmware. Instead of being stored in firmware, as is the BIOS, the UEFI code is stored in the /EFI/ directory in non-volatile memory.
Can you decompile firmware?
You can use binwalk to reverse engineer a firmware image to understand how it works. You can reverse engineer binaries inside filesystem images to look for vulnerabilities. You can decompress filesystem images to search for specific password files (passwd, shadow, etc) and try to break password hashes.
