DNS spoofing can lead to which outcome?

• A. Increased network reliability
• B. Cached data remains accurate
• C. Reduced risk of phishing
• D. Unauthorized access to sensitive information

Answer: (D)

DNS spoofing undermines how domain names map to IP addresses by returning a forged IP for a legitimate domain. When the resolver takes that fake address, traffic goes to an attacker-controlled host instead of the real site. That lets the attacker harvest sensitive information users submit—such as usernames, passwords, or other credentials—and can grant unauthorized access to accounts or data. In short, redirecting users to a malicious server through manipulated DNS directly enables theft or exposure of sensitive information.

It doesn’t improve reliability or integrity of the network; it actually degrades them. It also doesn’t keep cached data accurate—cached, poisoned results mislead future lookups. And it doesn’t reduce phishing risk; it can greatly increase it by making attackers’ sites appear legitimate.
