Suggested answer: C

Explanation:

An advanced persistent threat (APT) is a type of cyberattack that involves a stealthy and continuous process of compromising and exploiting a target system or network. An APT typically has a specific goal or objective, such as stealing sensitive data, disrupting operations, or sabotaging infrastructure. An APT can use various techniques to evade detection and maintain persistence, such as encryption, proxy servers, malware, etc. The scenario described in the question matches the characteristics of an APT.
