Can ffind output data for automated processing?

Yes, ffind supports a JSON output format using the '--format json' flag, making it ideal for integration into larger automated security pipelines.

What system dependencies are required to use this skill?

For full extraction capabilities, your system should have e2fsprogs, f2fs-tools, and util-linux installed.

What filesystems does ffind support for extraction?

The ffind skill currently supports the extraction of ext2, ext3, ext4, and F2FS filesystems from firmware images.

Can I use ffind to identify standard file types?

Yes. While ffind focuses on security-relevant artifacts by default, you can use the '-a' flag to identify and display all file types including common formats.

Why does the extraction feature require sudo privileges?

Filesystem extraction and mounting operations involve low-level system calls that require root access to interact with loop devices and filesystem drivers safely.

Security & Testing

Analyzes firmware files, detects file types, and extracts embedded filesystems for security research and IoT pentesting.

About

Ffind is a specialized security tool designed for analyzing firmware images and identifying critical file types within IoT devices. It automates the process of detecting file headers, identifying security artifacts, and performing deep filesystem extraction—including support for ext2/3/4 and F2FS. This skill is essential for security researchers and hardware pentesters who need to dissect firmware binaries, uncover vulnerabilities, or explore embedded environments efficiently within their Claude Code workflow.
