Cisco Certified Support Technician (CCST) CybersecurityNetwork SecurityMedium
A cybersecurity analyst is investigating a persistent threat actor that is using a variety of sophisticated techniques to evade detection and maintain long-term access to a target network. The attacker's goal is to exfiltrate sensitive intellectual property over an extended period without being noticed. Which of the following terms best describes this type of threat?
- ABrute-force attack
- BDenial-of-Service (DoS) attack
- CPhishing attack
- DAdvanced Persistent Threat (APT)
Show answer & explanationAnswer & explanation
Correct answer: D. Advanced Persistent Threat (APT)
An Advanced Persistent Threat (APT) is characterized by its long-term, stealthy nature, sophisticated techniques, and specific objectives, often involving data exfiltration. The scenario describes these exact characteristics.
Why the other options are wrong
- A. A brute-force attack attempts to guess credentials through trial and error, which is a specific tactic, not the broad description of a persistent, sophisticated threat actor.
- B. A DoS attack aims to disrupt service availability, not to maintain long-term, stealthy access for data exfiltration.
- C. A phishing attack is a method of acquiring sensitive information, often a precursor, but not the overarching description of a long-term, persistent compromise.
Advanced Persistent Threat (APT)
An APT is a prolonged and targeted cyberattack where an intruder gains access to a network and remains undetected for an extended period. The goal is typically data exfiltration or espionage.
- Long-term presence in the target network
- Uses sophisticated and stealthy techniques to evade detection
- Often state-sponsored or highly organized criminal groups
- Focuses on specific, high-value targets for data theft or espionage
Memory trick: APTs are Always Patient, Targeting stealthily.
