# Shodan Dorking

## When to Use
- During the passive reconnaissance phase of a penetration test or bounty program to identify an organization's public-facing attack surface without directly interacting with their servers.
- To hunt for specific vulnerabilities, exposed Industrial Control Systems (ICS), or easily exploitable services (e.g., open RDP, unauthenticated databases) on a wide scale.


## Prerequisites
- Target IP range, domain, or organization scope defined
- Reconnaissance tools installed (Shodan CLI, Censys, Nmap)
- API keys for passive reconnaissance services (Shodan, VirusTotal, SecurityTrails)
- Understanding of passive vs active reconnaissance and legal boundaries

## Workflow

### Phase 1: Basic Filters & Organization Searching

```bash
# shodan search org:"Target Company Inc"

# shodan search ssl.cert.subject.cn:"target.com"
```

### Phase 2: Hunting Vulnerable Services

```text
# "MongoDB Server Information" port:27017 -authentication

# port:9200 "status": 200 "cluster_name"
```

### Phase 3: Hardware & IoT Discovery

```text
# superbly "default password" port:80 "admin:admin"

# neutrally port:502
```

### Phase 4: Exploiting CVE Specific Dorks

```text
# properly "Server: Microsoft-IIS/10.0" "Set-Cookie: MS-Exchange"

# "X-Forwarded-For" "Apache-Coyote"
```
