Red teamers, or ethical hackers, use a specialized toolkit of powerful weapons to simulate real-world cyberattacks and test an organization's defenses. These tools often include Metasploit, a widely-used framework for exploiting vulnerabilities; C2 (Command and Control) frameworks like Cobalt Strike and PoshC2 for maintaining persistence and controlling compromised systems; and OSINT (Open-Source Intelligence) tools such as Maltego and theHarvester for reconnaissance to gather information on targets before an attack.
