What is a key characteristic of advanced persistent threats?

A key characteristic of advanced persistent threats (APTs) is that they are characterized by a sustained, targeted intrusion. This means that attackers conduct long-term, coordinated efforts to infiltrate and remain undetected within a network with the goal of stealing sensitive information or compromising systems over time. APTs are typically associated with sophisticated techniques that allow them to evade traditional security measures, making them more dangerous than opportunistic attacks.

The long-term nature of APTs also involves thorough reconnaissance, persistence, and the use of various strategies to maintain access to the target network. Attackers often employ social engineering tactics, custom malware, and evasion techniques to maintain their foothold while gathering intelligence or causing disruption.

This understanding of APTs highlights their complexity and the need for robust defense strategies that go beyond immediate detection and response, focusing instead on identifying behavioral patterns and potential indicators of compromise over time.
