Threat actors are individuals or groups that engage in malicious activities targeting computer systems, networks, or data. They can range from lone hackers to organized crime syndicates and even state-sponsored entities. Their motivations may include financial gain, political agendas, or simply the challenge of breaching security measures. These actors often employ various techniques, such as phishing, malware, or social engineering, to exploit vulnerabilities. Understanding the tactics of threat actors is crucial for organizations to develop effective cybersecurity strategies and protect sensitive information from potential breaches.
