## What it is
Firmwalker is a simple bash script that searches extracted or mounted firmware file systems for security-relevant files and content, such as password files, SSL certificates, configuration files, and sensitive keywords. It can optionally query the Shodan API and outputs its findings to a text report.

## Use cases
- analyze extracted router firmware for hardcoded credentials
- find SSL certificates and keys in a firmware image
- search IoT device file systems for sensitive configuration files
- audit firmware for passwords, URLs, and IP addresses
- scan embedded device rootfs for common vulnerable binaries

## When to choose
- you have an extracted or mounted firmware file system and want a quick, lightweight scan
- you want a simple bash-based tool without heavy dependencies
- you're doing IoT security research or firmware triage

## When to avoid
- you need deep binary analysis or emulation rather than file system grepping
- you want a maintained framework with active development and updates
- you need a GUI or automated pipeline integration
