Why is DNS cache poisoning dangerous?

DNS cache poisoning: Explanation

DNS cache poisoning, also known as DNS spoofing, is an attack that occurs when malicious or false data is inserted into a DNS cache server. This data corrupts the data stored in the server, causing it to respond to requests for a domain name with the wrong IP address. In other words, valid DNS requests that are received by a corrupted server will be answered with incorrect information, such as sending a user to the wrong website or to a malicious one. DNS spoofing is dangerous because it can manipulate information on the Internet allowing criminals to commit cybercrimes. It can also be used to redirect web traffic to sites that contain malicious software, leading to data breaches and other security threats.
