Which attack vector focuses on stealing data from a victim's machine without their knowledge?

• A. Confidentiality
• B. Cloud Computing Threats
• C. Advanced Persistent Threats (APT)
• D. Web Application Threats

Answer: (C)

Stealthy, long-term data theft describes an advanced persistent threat. An APT breaches a system, implants a foothold, and remains in the environment—often for months or years—while quietly moving through networks and exfiltrating data without the user noticing. The emphasis is on persistence and stealth: the attacker avoids detection and keeps access for extended periods to harvest information. This contrasts with general confidentiality as a principle, which is about preventing unauthorized disclosure, cloud threats that focus on risks to cloud infrastructure, and web application threats that target app vulnerabilities rather than covert on‑host data theft. So the scenario of stealing data from a victim’s machine without their knowledge aligns best with an advanced persistent threat.
