Binwalk
Firmware analysis and extraction — identify and extract embedded files from binary blobs.
Quick Start
# Install
apt install binwalk
# Scan firmware for signatures
binwalk firmware.bin
# Extract all found content
binwalk -e firmware.bin
# Output in _firmware.bin.extracted/
# Recursive extraction
binwalk -eM firmware.bin
Core Flags
| Flag | Purpose |
|------|---------|
| -e | Extract found files |
| -M | Recursive extraction (matryoshka) |
| -B | Signature scan (default) |
| -E | Entropy analysis |
| -A | Disassemble CPU instructions |
| -C DIR | Output directory |
| -q | Quiet mode |
| --dd TYPE:OFFSET:SIZE | Manual extraction |
| -l N | Limit extraction size |
Common Workflows
Full firmware analysis:
binwalk -eM firmware.bin -C ./extracted/
ls ./extracted/
Find compressed/encrypted regions (entropy):
binwalk -E firmware.bin
# High entropy = encrypted/compressed, low = plaintext
Find hardcoded strings after extraction:
binwalk -eM firmware.bin
find ./_firmware.bin.extracted/ -type f | xargs strings | grep -i "password\|admin\|key"
