DNS spoofing, also known as DNS cache poisoning, is a type of cyber attack where a malicious actor manipulates the Domain Name System (DNS) to redirect users to a fake website or server. This is achieved by altering the DNS records, which act as a directory for translating domain names into IP addresses. By spoofing the DNS, the attacker can trick users into unknowingly visiting a fraudulent website, potentially leading to the theft of sensitive information or the installation of malware. This type of attack can be particularly dangerous as it can go undetected and affect a large number of users. To protect against DNS spoofing, it is important to regularly update DNS records and use secure DNS protocols.
