Metasploit Framework

The world's most powerful penetration testing platform for vulnerability research and exploitation

Explore Report Risk Analysis

Overview

Metasploit is the world's most powerful and widely adopted open-source penetration testing framework. Originally developed in 2003 by H.D. Moore and now maintained by Rapid7, it empowers security professionals, red teamers, ethical hackers, and researchers with a flexible platform to discover, exploit, validate, and simulate vulnerabilities in real-world environments.

Tool Functions & Modular Architecture

Metasploit is built on a plug-and-play module system, enabling efficient development and execution of complex offensive security tasks.

1. Exploits

Target: Known CVEs in OSes, applications, and network services.

  • Over 2,000+ exploits span across Windows, Linux, macOS, IoT, CMSs, and legacy systems.
  • Supports exploit chaining to bypass layered defenses.

Examples:

EternalBlue (MS17-010)

Remote Windows SMB exploit

Shellshock

Remote command execution in Bash

MS08-067

Windows RPC remote code execution

2. Payloads

Executed after successful exploitation; deliver attacker control.

Types:

  • Reverse/Bind Shells
  • Staged/Stageless payloads

Meterpreter:

A powerful, memory-only payload offering:

  • Remote shell
  • Webcam/screen access
  • SAM dump (Windows credentials)
  • Privilege escalation & token impersonation
  • Network pivoting

3. Auxiliary Modules

Non-exploit tools for:

  • Port scanning
  • Banner grabbing
  • Service enumeration (HTTP, FTP, SNMP)
  • Password brute-forcing
  • Protocol fuzzing
  • DoS simulation

Examples:

scanner/portscan/tcp
scanner/http/wordpress_login_enum

4. Encoders

Obfuscate payloads to bypass AV and EDR.

  • Recursive encoding allowed.

Examples:

shikata_ga_nai
cmd/powershell_base64

5. Post-Exploitation

Execute after initial access to maintain control and escalate.

Capabilities:

  • Credential dumping (LSASS)
  • Lateral movement (via SMB, RDP)
  • Persistence via registry/services
  • Keystroke logging
  • Session migration and user impersonation
  • UAC bypass

6. Integration & Automation

  • Nmap support: db_nmap integrates with Metasploit DB.
  • PostgreSQL: Stores hosts, sessions, loots, and history.
  • Compatible with Nexpose, Burp Suite, Wireshark, and OpenVAS.

Advanced Network Attack Capabilities

Metasploit enables multi-stage, multi-protocol, real-world adversary emulation:

Reconnaissance

Scans and identifies:

  • Live hosts
  • OS types and versions
  • Service banners
  • Vulnerable ports
  • Fingerprinting (e.g., SMBv1, SNMP community strings)

Exploitation

Protocols:

  • SMB
  • RDP
  • Telnet
  • HTTP(S)
  • FTP
  • LDAP
  • DNS
  • SNMP

Web Exploits:

WordPress, Joomla, Drupal RCEs

Client-Side:

Malicious file exploits (PDF/DOCX), Browser Autopwn

Lateral Movement & Pivoting

Route traffic through a compromised host using:

  • Session routing
  • SOCKS proxies
  • VPN pivot tunnels

Combine with DNS tunneling or encrypted payloads for stealth.

Version Evolution & Meterpreter Deep Dive

Metasploit Framework (Open Source)

  • CLI interface for scripting, custom module development, and deep manual control

Metasploit Pro (Commercial)

  • Web-based UI
  • Drag-and-drop attack workflows
  • Phishing campaign wizards
  • Collaboration and exportable reports

Recent Milestones (2021–2025+)

  • ARM64 & RISC-V payloads
  • Certifried (Active Directory CS RCE)
  • Kerberos credential theft
  • DNS session pivoting with custom resolver
  • LDAP enumeration post-modules

Meterpreter Enhancements

  • Reflective DLL injection for in-memory execution
  • Mimikatz token theft integration
  • Process migration, screenshare, and encrypted channels
  • Dynamic loadable extensions for new capabilities

Risk Assessment – Legal vs Malicious Use

Ethical Applications

  • Corporate penetration testing
  • Red team/blue team simulations
  • Security awareness training
  • Vulnerability validation
  • Cybersecurity certifications (e.g., OSCP, CEH)

Misuse Scenarios

  • Script-kiddies using default payloads for opportunistic attacks
  • APT actors using modified Meterpreter for stealth
  • Social engineering delivery via email phishing and weaponized documents
  • Cloud-based deployments for anonymous attacks

Detection & Evasion

  • Out-of-box payloads = easily detected
  • Detection signatures exist in most IDS/EDRs

Requires:

  • Obfuscation (via encoders)
  • In-memory only execution (e.g., Meterpreter)
  • Secure delivery via HTTPS, DNS, or SMB
