# Analyzing Breach Credential Databases

## Overview

Analyze compromised credential databases to identify password patterns, reuse, and organizational exposure.

## Prerequisites

| Tool / Requirement | Details |
|---|---|
| `dehashed` | Security tooling |
| `h8mail` | Security tooling |
| `pwndb-tool` | Security tooling |
| Isolated lab environment for testing | Environment requirement |
| Authorization and signed Rules of Engagement (RoE) | Environment requirement |
| Relevant target samples or systems acquired through authorized channels | Environment requirement |

## Quick Reference

```bash
# Initialize working environment
mkdir -p /tmp/analyzing-breach-credential-databases/{output,logs,artifacts}

# Execute primary analysis with dehashed
echo "[*] Running Analyzing Breach Credential Databases with dehashed..."

# Validate results with h8mail
echo "[*] Cross-validating with h8mail..."

# Generate summary report
cat /tmp/analyzing-breach-credential-databases/output/report.json
```

## Workflow

### Step 1: Preparation and Reconnaissance

```bash
# Identify target and gather initial intelligence
file ./target_sample
dehashed --version 2>/dev/null || echo "Install dehashed"

# Set up working directory
mkdir -p /tmp/analyzing-breach-credential-databases/{output,logs,artifacts}
```

### Step 2: Primary Analysis

```bash
# Execute primary analysis with dehashed
# Refer to Quick Reference above for detailed commands
echo "[*] Running Analyzing Breach Credential Databases with dehashed..."

# Log all operations
script -q /tmp/analyzing-breach-credential-databases/logs/session.log
```

### Step 3: Deep Investigation

```bash
# Apply h8mail for secondary analysis
echo "[*] Deep investigation with h8mail..."

# Cross-reference findings
diff /tmp/analyzing-breach-credential-databases/output/primary.json /tmp/analyzing-breach-credential-databases/output/secondary.json
```

### Step 4: Documentation and Reporting

```bash
# Generate structured findings report
cat <<'EOF' > /tmp/analyzing-breach-credential-databases/output/report.json
{
  "technique": "analyzing-breach-credential-databases",
  "domain": "password-cracking",
  "tools_used": ["dehashed", "h8mail"],
  "findings": [],
  "recommendations": []
}
EOF
```

## Verification

- [ ] Environment and tools verified and operational
- [ ] Target samples acquired through authorized channels
- [ ] Primary analysis completed with findings documented
- [ ] Secondary validation performed with independent tooling
- [ ] All artifacts preserved in structured output directory
- [ ] Detection opportunities documented for blue team
