A company discovered that terabytes of data have been exfiltrated over the past year after an employee clicked on an email link. The threat continued to evolve and remain undetected until a security analyst noticed an abnormal amount of external connections when the employee was not working. Which of the following is the MOST likely threat actor?
Correct Answer: C
An APT attack is characterized by using toolkits to achieve a presence on a target network and then, instead of just moving to steal information, focusing on the long game by maintaining a persistent presence on the target network. The tactics, tools, and procedures of APTs are focused on maintaining administrative access to the target network and avoiding detection. Then, over the long haul, the attacker can remove intellectual property and more from the organization, typically undetected.
