Metasploit is a penetration testing tool used by cybersecurity professionals to identify and exploit vulnerabilities in networks, systems, and applications. It helps security teams simulate real-world attacks to test their defenses, and it provides a framework for developing and executing exploit code, scanning networks, and evading detection.

While it is impossible to completely bypass Windows Defender's defenses, there are numerous techniques attackers use to evade it. For security researchers, bypassing certain Windows Defender protections qualifies for Microsoft's bug bounty program, providing a financial incentive for discovering and responsibly disclosing vulnerabilities.
