Extracting & Analyzing Filesystems from Firmware
Carve, identify, and mount the embedded filesystems hidden inside firmware images to recover the binaries, configs, and keys they contain.
Inside the Firmware Blob
You can analyze firmware images, emulate embedded binaries, and use hardware-assisted debugging. Most firmware is more than code: it embeds entire filesystems holding executables, web pages, and secrets.
Extracting them is often where the real findings live.
Firmware Layout
A typical image is a stack of regions:
- Bootloader
- Kernel
- One or more root filesystems
- Configuration / NVRAM areas
Each region may use a different format and compression.
