infiltrator

An infiltrator is someone who secretly enters or gains access to a place, organization, or group without permission, often to gather information, cause harm, or disrupt operations. They typically conceal their identity or intentions to avoid detection. Infiltrators can be individuals working for outside entities, such as spies or adversaries, or insiders acting covertly. Their goal is usually to collect sensitive data, influence decisions, or sabotage from within. Recognizing and preventing infiltration is critical for security and maintaining trust within organizations and communities.
