# **The Ultimate Guide to Recon-ng: Professional Web Reconnaissance Framework**

Recon-ng is a modular web reconnaissance framework developed by Tim Tomes, widely recognized as one of the most powerful open-source intelligence (OSINT) collection tools for penetration testing and red team operations. Its Metasploit-inspired design provides security professionals with a standardized reconnaissance workflow.

## **1. Core Advantages of Recon-ng**

### **Architectural Features**
- **Modular design**: 200+ pluggable reconnaissance modules
- **Unified workspace**: Centralized project data management
- **Automation capabilities**: Supports workflow scripting
- **Multi-source integration**: Built-in interfaces for 30+ data sources
- **Standardized output**: Structured data reporting

    "Credential Enumeration" : 15
    "Network Mapping" : 10
    "Reporting" : 5
```

## **2. Installation & Initialization**

### **Installation Methods**
```bash
# Kali Linux (pre-installed)
sudo apt install recon-ng

# Manual installation
git clone https://github.com/lanmaster53/recon-ng.git
cd recon-ng && pip install -r REQUIREMENTS
```

### **Workspace Management**
```bash
# Launch and create workspace
recon-ng
workspaces create pentest_company
```

## **3. Core Module Breakdown**

### **Information Gathering Modules**
| Module Path | Description |
|-------------|-------------|
| `recon/domains-hosts/brute_hosts` | Subdomain brute-forcing |
| `recon/domains-hosts/certificate_transparency` | Certificate Transparency log queries |
| `recon/domains-hosts/google_site_web` | Google site search |

### **Data Processing Modules**
```bash
# Deduplication module
modules load reporting/deduplicate

# JSON export
modules load reporting/json
```

## **4. Practical Workflows**

### **Enterprise Asset Discovery**
```bash
workspaces create acme_corp
db insert domains acme.com
modules load recon/domains-hosts/brute_hosts
options set SOURCE acme.com
run
```

### **Employee Information Gathering**
```bash
modules load recon/companies-contacts/namechk
options set SOURCE acme.com
run
```

### **Automated Report Generation**
```bash
modules load reporting/html
options set CREATOR "Security Team"
run
```

## **5. Advanced Techniques**

### **API Key Configuration**
```bash
keys add virustotal_api YOUR_API_KEY
keys add shodan_api YOUR_API_KEY
```

### **Custom Module Development**
```python
from recon.core.module import BaseModule

class MyModule(BaseModule):
    def run(self):
        self.alert('Custom module executed!')
```

### **Workflow Automation**
```bash
# Save workflow
workflows backup acme_workflow

# Execute workflow
workflows load acme_workflow
```

## **6. Defense Strategies**

### **Enterprise Protection Recommendations**
- **Monitor data leaks**: Deploy Certificate Transparency log monitoring
- **Limit public information**: Control WHOIS information exposure
- **Employee training**: Prevent social engineering
- **Regular audits**: Review digital footprints

### **Detection Methods**
- Analyze abnormal API call patterns
- Monitor sensitive data search behavior
- Deploy threat intelligence platforms
