Advanced Persistent Threat (APT)
A cyber attack that uses sophisticated techniques to conduct cyber espionage or other malicious activity on an ongoing basis against targets such as governments and companies. Typically conducted by an adversary with sophisticated levels of expertise and significant resources – frequently associated with nation-state players.
