Techopedia Explains DNS Cache Poisoning
DNS cache poisoning works when the security controls of a DNS server are compromised and accessed by a hacker. The hacker replaces a website’s associated DNS records with a different website, one that may contain spam, malware and/or viruses. This is done by changing the associated domain name’s IP address to that of the malicious website. When the user accesses the target website from the corrupted DNS server, the hacker’s website appears as opposed to the original website.
