What is a common consequence of DNS spoofing attacks?

• A. Increased network visibility.
• B. Authorized access to sensitive information.
• C. Unauthorized access to sensitive information, such as outgoing emails.
• D. Improved email deliverability.

Answer: (C)

DNS spoofing tricks a device into trusting a false address by returning forged DNS responses, so the user ends up connecting to an attacker-controlled server instead of the legitimate one. When traffic is directed to a malicious host, sensitive data—such as credentials or the content of outgoing emails—can be intercepted or viewed by someone other than the intended recipient. That makes unauthorized access to sensitive information the most likely and impactful consequence of this kind of attack. The other outcomes described don’t fit with how DNS spoofing works. It doesn’t inherently increase network visibility for legitimate users, and it doesn’t improve email deliverability; in practice, it can disrupt connectivity and reliability rather than enhance it.
