## What it does

This skill guides forensic examination of raw (dd), E01, or AFF disk images. It covers both Autopsy GUI ingest pipelines and command-line forensics using The Sleuth Kit.

The workflow inspects partition tables with `mmls`, inspects inode metadata with `istat`, and extracts deleted files using `icat` and `tsk_recover`. Inside Autopsy, ingest modules automate hash matching against the NSRL database, flag encrypted containers, and index text for regex search.

The case database grows to two or three times the source image size. Storage space requires planning before ingest starts. Running Autopsy also demands JRE 8 or newer and at least 8GB of RAM.

## Install

### Claude Code (native platform)

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add mukul975/Anthropic-Cybersecurity-Skills --skill analyzing-disk-image-with-autopsy -a cursor
```

2. **Manually: put the files in place**
- File: `.cursor/skills/analyzing-disk-image-with-autopsy/SKILL.md` — Cursor also reads .agents/skills/ and .claude/skills/

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install mukul975/Anthropic-Cybersecurity-Skills analyzing-disk-image-with-autopsy
```

2. **Manually: put the files in place**
- File: `.github/skills/analyzing-disk-image-with-autopsy/SKILL.md`

### Gemini CLI

1. **Skills CLI (Vercel)**
```bash
npx skills add mukul975/Anthropic-Cybersecurity-Skills --skill analyzing-disk-image-with-autopsy -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/mukul975/Anthropic-Cybersecurity-Skills --path skills/analyzing-disk-image-with-autopsy
```

### Windsurf (Devin Desktop)

**Manually: put the files in place**
- File: `.devin/skills/analyzing-disk-image-with-autopsy/SKILL.md` — The legacy .windsurf/skills/ path still works

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add mukul975/Anthropic-Cybersecurity-Skills --skill analyzing-disk-image-with-autopsy -a opencode
```

### Claude.ai

**Claude.ai**
- Zip the folder and upload it in Settings → Capabilities → Skills

Where a file is given instead of a command, copy the files from the source to that path: https://github.com/mukul975/Anthropic-Cybersecurity-Skills/tree/HEAD/skills/analyzing-disk-image-with-autopsy/SKILL.md

## When to use it
- recover deleted files using `icat` and `tsk_recover`
- inspect partition tables with `mmls`
- filter known-good operating system files via NSRL hashes
- construct file activity timelines for incident reporting

## Example prompts
- Check partition layout and list deleted files inside evidence.dd
- Extract the deleted document at inode 14523 using icat
- Configure Autopsy ingest modules to match against NSRL hashes

# Analyzing Disk Image with Autopsy

## When to Use
- When you have a forensic disk image and need structured analysis of its contents
- During investigations requiring file recovery, keyword searching, and timeline analysis
- When non-technical stakeholders need visual reports from forensic evidence
- For examining file system metadata, deleted files, and embedded artifacts
- When building a comprehensive case from multiple disk images

## Prerequisites
- Autopsy 4.x installed (Windows) or Autopsy 4.x with The Sleuth Kit (Linux)
- Forensic disk image in raw (dd), E01 (EnCase), or AFF format
- Minimum 8GB RAM (16GB recommended for large images)
- Java Runtime Environment (JRE) 8+ for Autopsy
- Sufficient disk space for the Autopsy case database (2-3x image size)
- Hash databases (NSRL, known-bad hashes) for file identification

## Workflow

### Step 1: Install Autopsy and Configure Environment

```bash
# On Linux, install Sleuth Kit and Autopsy
sudo apt-get install autopsy sleuthkit

# Download Autopsy 4.x (GUI version) from official source
wget https://github.com/sleuthkit/autopsy/releases/download/autopsy-4.21.0/autopsy-4.21.0.zip
unzip autopsy-4.21.0.zip -d /opt/autopsy

# On Windows, run the MSI installer from sleuthkit.org
# Launch Autopsy
/opt/autopsy/bin/autopsy --nosplash

# For Sleuth Kit command-line analysis alongside Autopsy
sudo apt-get install sleuthkit
```

### Step 2: Create a New Case and Add the Disk Image

```
1. Launch Autopsy > "New Case"
2. Enter Case Name: "CASE-2024-001-Workstation"
3. Set Base Directory: /cases/case-2024-001/autopsy/
4. Enter Case Number, Examiner Name
5. Click "Add Data Source"
6. Select "Disk Image or VM File"
7. Browse to: /cases/case-2024-001/images/evidence.dd
8. Select Time Zone of the original system
9. Configure Ingest Modules (see Step 3)
```

```bash
# Alternatively, use Sleuth Kit CLI to verify the image first
