# Performing Impersonation Attack Testing

## Overview

Test organizational resilience against impersonation attacks including executive fraud, vendor impersonation, and authority exploitation.

## Prerequisites

| Tool / Requirement | Details |
|---|---|
| `spoofcheck` | Security tooling |
| `dmarc-analyzer` | Security tooling |
| `caller-id-spoof` | 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/performing-impersonation-attack-testing/{output,logs,artifacts}

# Execute primary analysis with spoofcheck
echo "[*] Running Performing Impersonation Attack Testing with spoofcheck..."

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

# Generate summary report
cat /tmp/performing-impersonation-attack-testing/output/report.json
```

## Workflow

### Step 1: Preparation and Reconnaissance

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

# Set up working directory
mkdir -p /tmp/performing-impersonation-attack-testing/{output,logs,artifacts}
```

### Step 2: Primary Analysis

```bash
# Execute primary analysis with spoofcheck
# Refer to Quick Reference above for detailed commands
echo "[*] Running Performing Impersonation Attack Testing with spoofcheck..."

# Log all operations
script -q /tmp/performing-impersonation-attack-testing/logs/session.log
```

### Step 3: Deep Investigation

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

# Cross-reference findings
diff /tmp/performing-impersonation-attack-testing/output/primary.json /tmp/performing-impersonation-attack-testing/output/secondary.json
```

### Step 4: Documentation and Reporting

```bash
# Generate structured findings report
cat <<'EOF' > /tmp/performing-impersonation-attack-testing/output/report.json
{
  "technique": "performing-impersonation-attack-testing",
  "domain": "social-engineering",
  "tools_used": ["spoofcheck", "dmarc-analyzer"],
  "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
