msfdb init
msfconsole
```

## Introduction
Metasploit Framework is an open-source penetration testing platform maintained by Rapid7 and a large contributor community. It gives security professionals a structured way to find vulnerabilities, develop exploits, and validate defenses with thousands of ready-to-use modules.

## What Metasploit Does
- Ships over 2,000 exploit modules targeting known vulnerabilities in operating systems, services, and applications
- Provides auxiliary modules for network scanning, fuzzing, and credential testing
- Generates payloads for multiple platforms and architectures
- Offers post-exploitation modules for privilege escalation and lateral movement
- Integrates with external scanners like Nessus, Nexpose, and OpenVAS

## Architecture Overview
Built in Ruby, Metasploit uses a modular architecture with a core engine that handles sessions, module loading, and database interactions. Modules are split into exploits, payloads, auxiliary, post, encoders, and evasion categories. A PostgreSQL backend stores host data, credentials, and findings. The primary interface is msfconsole, with an RPC API available for automation.

## Self-Hosting & Configuration
- Install via the omnibus installer on Linux, macOS, or Windows
- Requires PostgreSQL for the backend database; run `msfdb init` on first use
- Configure `database.yml` for custom connection settings
- Use `.rc` resource scripts to automate repetitive testing workflows
- Update modules regularly with `msfupdate` or by pulling from GitHub

## Key Features
- Meterpreter payload with in-memory execution and encrypted channels
- Built-in evasion framework for testing endpoint protection controls
- Session management for handling multiple targets simultaneously
- Active community adding modules for recently disclosed CVEs
- Extensive API for scripting and integration with CI/CD security pipelines

## Comparison with Similar Tools
- **Cobalt Strike** — commercial C2 with advanced red-team features; Metasploit is free and open source
- **Burp Suite** — focuses on web app testing; Metasploit covers network-level exploitation
- **Nuclei** — template-based vulnerability scanner; Metasploit adds active exploitation and post-exploitation
- **Core Impact** — enterprise pen-testing suite; Metasploit provides comparable depth at no cost

## FAQ
**Q: Is Metasploit legal to use?**
A: Yes, when used on systems you own or have written authorization to test. Unauthorized use is illegal.

**Q: What is the difference between Framework and Pro?**
A: Framework is the free open-source edition. Pro adds a web GUI, automated workflows, and compliance reporting.

**Q: Does it require root privileges?**
A: Some features like raw sockets need root. Most modules work without elevated privileges.

**Q: How often are new modules added?**
A: The community and Rapid7 contribute new modules weekly, typically within days of public vulnerability disclosures.
