Metasploit Framework

Metasploit Framework is an open-source penetration testing platform that enables security professionals to develop, test, and execute exploit code against remote target systems. Created by HD Moore in 2003 as a portable network game using Perl, acquired by Rapid7 in 2009, the project has over 34,000 stars as of 2026 and is the world's most widely used penetration testing framework. Key features include: exploit modules (over 2,300 exploits targeting operating systems, applications, web servers, network devices, and IoT firmware with documented CVE references), auxiliary modules (over 1,300 scanners, fuzzers, protocol brute-forcers, and reconnaissance tools that do not require payload execution), post-exploitation modules (over 500 modules for privilege escalation, credential harvesting, persistence, lateral movement, and data exfiltration after initial compromise), payloads (Meterpreter memory-resident payload providing interactive shell, file operations, process migration, screenshot capture, and keystroke logging, plus staged and stageless payload formats), encoders (pack and transform payloads to evade signature-based detection including Shikata Ga Nai polymorphic encoder), database integration (PostgreSQL backend for workspace management, host tracking, service enumeration, vulnerability correlation, and credential storage), Nmap integration (import Nmap XML results and run db_nmap commands directly), and cross-platform (Kali Linux, Ubuntu, Windows, macOS, Docker).
