Advanced Persistent Threat (APT)
In an APT attack, a threat actor uses the most sophisticated tactics and technologies to penetrate a high-profile network. APTs aim to stay ‘under the radar’ and explore the network while remaining undetected for weeks, months, and even years. APTs are most often used by nation-state threat actors wishing to cause severe disruption and damage to the economic and political stability of a country. They can be considered the cyber equivalent of espionage ‘sleeper cells’.
