Domain Name Server (DNS) spoofing

What is DNS spoofing?

DNS spoofing, also known as DNS cache poisoning, is a cyber attack where attackers introduce corrupt DNS data into the DNS resolver's cache. This causes the DNS server to return an incorrect IP address, diverting traffic to malicious websites without the user's knowledge. The spoofed sites can be used to steal sensitive information, distribute malware, or carry out phishing attacks. DNS spoofing compromises the integrity of the internet's address book, making it a significant security threat.
