What is the primary purpose of DNS poisoning?

• A. To enhance website performance
• B. To redirect users to a malicious URL
• C. To strengthen security protocols
• D. To recover lost data

Answer: (B)

The primary purpose of DNS poisoning, also known as DNS spoofing, is to redirect users to a malicious URL. This technique involves corrupting the DNS cache of a target system or server, whereby false DNS records are introduced. When a user attempts to access a legitimate website, the poisoned DNS record directs them instead to an attacker-controlled site. This can lead to various malicious activities, including phishing attacks, where users unwittingly provide sensitive information, or the distribution of malware. In contrast, other options do not align with the purpose of DNS poisoning. Enhancing website performance is typically achieved through caching and optimization techniques rather than by malicious manipulation of DNS records. Strengthening security protocols is an objective of cybersecurity measures, but it is not relevant to the act of DNS poisoning. Similarly, recovering lost data refers to data recovery processes that are unrelated to the purpose of tampering with DNS queries. Thus, the focus of DNS poisoning as a malicious technique centers on redirection for nefarious purposes.
