An APT (advanced persistent threat) is a targeted attack in which a well-resourced group gets into an organization's network and stays hidden for weeks or months to steal information or set up a larger strike. Unlike an opportunistic attack, an APT picks its victim and moves slowly, changing tactics to avoid detection.
