Which of the following is a common tactic used in cyber espionage?

Phishing attacks are a common tactic used in cyber espionage because they are designed to trick individuals into revealing sensitive information, such as passwords or personal details. This technique exploits human psychology, often involving deceptive emails or messages that appear legitimate, allowing attackers to compromise accounts and access confidential data. By successfully executing a phishing attack, cyber criminals can gather intelligence, maintain persistent access to a network, or even deploy more advanced threats.

In the context of cyber espionage, the aim is often to acquire sensitive or classified information from organizations or institutions, and phishing serves as an effective entry point for attackers. This tactic is particularly appealing because it does not necessarily require extensive technical skills but instead relies on manipulation and social engineering, making it a prevalent method among threat actors targeting valuable information.
