In the vast internet landscape, where we browse, shop, and communicate daily, a hidden threat lurks that can potentially compromise our digital safety: DNS poisoning. This strange term can have far-reaching consequences, impacting individuals and organisations. In this blog post, we’ll explore the concept of DNS poisoning, understand how it works, and discover practical ways to protect ourselves from this invisible menace.
Understanding DNS Poisoning
DNS poisoning, also known as DNS cache poisoning or DNS spoofing, is a malicious attack on the DNS system designed to mislead it and redirect users to fraudulent or harmful websites. In a typical DNS poisoning attack, the attacker corrupts the DNS cache of a server or a user’s computer, replacing legitimate IP address information with malicious ones.
Once the DNS cache is poisoned, users who attempt to access a particular website are unknowingly redirected to a rogue website, often designed to mimic the legitimate site. These malicious websites are commonly used to steal sensitive information, such as login credentials, credit card details, or personal data, leading to identity theft, financial loss, and potential damage to the reputation of individuals or businesses.
