What are the methods and techniques used in espionage?

Espionage, the act of gathering confidential information for political, military, or economic purposes, employs various methods and techniques to achieve its objectives. Covert agents often rely on human intelligence, using spies or informants to gather information from trusted sources within targeted organizations or governments. Electronic surveillance plays a significant role through techniques like wiretapping, hacking, or intercepting communications. Technical intelligence involves leveraging advanced technology to collect information from satellite imagery, cyberattacks, or monitoring foreign networks. Counterintelligence is employed to detect and thwart espionage efforts by identifying and neutralizing foreign spies or moles within one's own organization. Other methods include signals intelligence, where information is gathered from intercepted radio signals, and open-source intelligence, which involves collecting information from public sources. Espionage techniques continue to evolve with advancements in technology, posing challenges for intelligence agencies worldwide.
