Metasploit

Rapid7 Metasploit is an open-source penetration testing framework maintained collaboratively by Rapid7 and the open-source community. It is available in two editions: Metasploit Framework (free, open-source) and Metasploit Pro (commercial, with additional features and support). Primary Functions: - Provides a library of exploit modules targeting known vulnerabilities across a wide range of software, operating systems, and services - Enables security teams to verify whether vulnerabilities are exploitable in their environments - Supports post-exploitation capabilities including payload delivery, privilege escalation, and lateral movement - Facilitates security assessments and penetration testing engagements from reconnaissance through exploitation Key Capabilities: - Exploit development and execution against target systems - Payload generation (including Meterpreter shells) for post-exploitation activity - Auxiliary modules for scanning, enumeration, and fingerprinting - Evasion primitives for bypassing security controls (notably in Metasploit Pro 5.1 for HTTP Meterpreter payloads) - Module-based architecture allowing community contributions of new exploits and auxiliary tools - JSON-RPC API for programmatic interaction and automation - Service hierarchy tracking (Metasploit Pro) - Integration with Rapid7's InsightVM for vulnerability management workflows - Active community development via GitHub with regular module additions Metasploit Framework is distributed as open-source software under a BSD-style license. Metasploit Pro is a commercial product offered by Rapid7 with enterprise features, a web-based UI, and dedicated support. The framework is widely used by penetration testers, red teams, and security researchers for authorized security testing.
