What does DNS spoofing involve?

DNS spoofing, also known as DNS cache poisoning, involves redirecting users to fake websites by corrupting the DNS resolution process. In this attack, the attacker alters the DNS records stored in a DNS server's cache to point a domain name to the wrong IP address. For example, when a user tries to visit a legitimate website, the compromised DNS server may return the IP address of a malicious site instead. This misleading redirection can lead users to phishing sites designed to steal personal information or to sites that deliver malware.

This tactic exploits the trust users place in the DNS system, allowing attackers to mislead them into thinking they are accessing a legitimate site while they are, in fact, on a fraudulent one. Understanding this process is essential for recognizing vulnerabilities within network security and the importance of securing DNS infrastructure to prevent such attacks.
