Install
Run the command in your project. The CLI asks which agents to install for.
- 02
Describe the task
Ask your agent for something this skill covers. It loads ffind automatically when relevant.
- 03
Review the result
The agent follows the SKILL.md steps, scripts and references bundled with the skill.

Ffind - Advanced File Finder with Extraction
You are helping the user find and analyze files with advanced type detection and optional filesystem extraction capabilities using the ffind tool.
Tool Overview
Ffind analyzes files and directories, identifies file types, and can extract filesystems (ext2/3/4, F2FS) for deeper analysis. It's designed for firmware and IoT device analysis.
Instructions
When the user asks to analyze files, find specific file types, or extract filesystems:
-
Understand the target:
- Ask what path(s) they want to analyze
- Determine if they want to extract filesystems or just analyze
- Ask if they want all file types or just artifact types
-
Execute the analysis:
- Use the ffind command from the iothackbot bin directory
- Basic usage:
ffind <path> [<path2> ...] - To extract filesystems:
ffind <path> -e - Custom extraction directory:
ffind <path> -e -d /path/to/output - Show all file types:
ffind <path> -a - Verbose output:
ffind <path> -v
-
Output formats:
--format text(default): Human-readable colored output with type summaries--format json: Machine-readable JSON--format quiet: Minimal output
-
Extraction capabilities:
- Supports ext2/ext3/ext4 filesystems (requires e2fsprogs)
- Supports F2FS filesystems (requires f2fs-tools)
- Requires sudo privileges for extraction
- Default extraction location:
/tmp/ffind_<timestamp>
Examples
Analyze a firmware file to see file types:
ffind /path/to/firmware.bin
Extract all filesystems from a firmware image:
sudo ffind /path/to/firmware.bin -e
Analyze multiple files and show all types:
ffind /path/to/file1.bin /path/to/file2.bin -a
Extract to a custom directory:
sudo ffind /path/to/firmware.bin -e -d /tmp/my-extraction
Important Notes
- Name collision: The Sleuth Kit also ships a
ffind(it finds file names for a given inode and takes a disk image plus an inode number). Ifwhich ffindpoints at/usr/bin/ffindor/usr/local/bin/ffind, the iothackbot flags below (-e,-d <dir>,-a,--format) will be misread by the wrong binary. Confirm withffind --help(the iothackbot tool shows--extract/--format); if it showsimage inodeusage, invoke the iothackbot tool by its full path in the repobin/directory instead. - Extraction requires root/sudo privileges
- Requires external tools: e2fsprogs, f2fs-tools, util-linux
- Identifies "artifact" file types relevant to security analysis by default
- Use
-aflag to see all file types including common formats
FAQ
What does the ffind skill do?
Advanced file finder with type detection and filesystem extraction for analyzing firmware and extracting embedded filesystems. Use when you need to analyze firmware files, identify file types, or extract ext2/3/4 or F2FS filesystems.
How do I install ffind?
Run npx skills add https://github.com/brownfinesecurity/iothackbot --skill ffind in your project. The skills CLI detects the agents you use and copies the skill into the right folder. For Claude Code you can also place the skill folder at ~/.claude/skills/ffind/ (personal) or .claude/skills/ffind/ (project).
Which AI agents can use ffind?
Any agent that supports the open Agent Skills format (a folder with a SKILL.md file), including Claude Code, Codex, Cursor, GitHub Copilot, Gemini CLI, Windsurf, Cline, OpenCode and more.
Is ffind safe to install?
No partner security audit is available yet. Skills can run commands and scripts, so read the SKILL.md and any bundled files before installing.
