Advanced Persistent Threats (APTs) represent a category of cyber threats characterized by their sophistication, prolonged presence, and targeted nature. These threats typically involve a group of attackers employing various tactics to gain unauthorized access to networks and remain undetected for extended periods. APTs can target specific organizations, governmental bodies, or individuals, making them a significant concern in the realm of cybersecurity. Understanding how APTs operate, their common tools, and defense strategies is crucial for protecting sensitive information and maintaining data integrity.
