What does a DNS server hijacking attack accomplish?

• A. It enhances server performance
• B. It redirects clients to a malicious website
• C. It secures the DNS mapping settings
• D. It prevents unauthorized access to the server

Answer: (B)

A DNS server hijacking attack primarily aims to redirect clients to a malicious website. This type of attack occurs when an attacker gains unauthorized access to the DNS settings of a server, allowing them to change the resolution of domain names. For instance, instead of directing users to the legitimate site they intended to visit, the compromised DNS server can direct them to a fraudulent site controlled by the attacker. This can facilitate various malicious activities such as phishing, where users may inadvertently enter sensitive information, or drive-by downloads, leading to malware infections. The other options do not accurately reflect the nature of a DNS hijacking attack. Enhancing server performance or securing DNS mapping settings does not align with the malicious intent of hijacking. Similarly, preventing unauthorized access to the server contradicts the very premise of a hijacking attack, which is inherently about gaining that unauthorized access to exploit the DNS system.
