What’s an Advanced Persistent Threat (APT)? A Brief Definition
Advanced Persistent Threats (APTs) are a cybercrime category typically directed at business and political targets. APTs require a high degree of stealthiness over a prolonged duration of operation in order to be successful. Therefore, the attack objectives typically extend beyond immediate financial gain and compromised systems continue to be of service even after key systems have been breached and initial goals reached.
Definitions of precisely what an APT is can vary widely, but can best be summarized in this brief whitepaper.
