Which factor makes DNS attractive for abuse?

• A. It is encrypted by default.
• B. It is trusted and rarely blocked.
• C. It never uses subdomains.
• D. It requires VPN to access.

Answer: (B)

DNS is attractive for abuse because it is trusted and rarely blocked. It underpins almost all Internet activity, so security controls typically allow DNS traffic to pass; blocking it would disrupt normal services. That permissiveness lets malicious actors use DNS for hosting, command-and-control, or data exfiltration while blending in with legitimate domain lookups, making it a low-friction channel for abuse.
