Espionage

Espionage, or spying, is a practice of getting information without permission about an organization, society, or country that is meant to be secret or confidential. Espionage usually involves having access to where the needed information is stored or to the people that know the information. In wartime, espionage is a war crime. 

A person who is unwillingly being spied upon or willingly gives away information is called an intelligence asset. The person who receives information is called a spy or more vaguely an agent. A double agent is one who trades information to both sides and is sometimes unknowingly related to or employed by both sides.
