If you\u2019re interested in a detailed exploration, read on for extensive information and practical advice.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The internet works on trust. Every time you type a website address into your browser\u2014like <em><strong>oflox.com<\/strong><\/em> or <em><strong>google.com<\/strong><\/em>\u2014your device relies on a system called <strong>DNS (Domain Name System)<\/strong> to translate that address into an IP (Internet Protocol) number. Without DNS, we would have to remember long strings of numbers instead of simple names.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">But what if this trust is broken? What if attackers trick your device into connecting to a fake website that looks like the original but is designed to steal your data? This is exactly what happens in a <strong>DNS Cache Poisoning attack<\/strong>.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">DNS cache poisoning (also called <strong>DNS spoofing<\/strong>) is one of the most dangerous cyber threats because it doesn\u2019t just affect one user\u2014it can affect thousands or even millions by corrupting the DNS records stored in resolvers.<\/p>\n\n\n\n<figure

injects false DNS records into the cache of a resolver. As a result, users are redirected to malicious websites even when they enter the correct domain name.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">For example, you type <em><strong>www.bankofindia.com<\/strong><\/em>, but instead of landing on the real bank\u2019s site, you\u2019re silently redirected to a fake clone created by attackers. This fake site may look identical but is designed to steal your login credentials, OTPs, or personal information.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">In technical terms, DNS cache poisoning manipulates the <strong>resolver\u2019s cache<\/strong>, making it serve <strong>fraudulent IP addresses<\/strong> instead of genuine ones.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"h-how-does-dns-cache-poisoning-work\"><span class=\"ez-toc-section\" id=\"How_Does_DNS_Cache_Poisoning_Work\"><\/span>How Does DNS Cache Poisoning Work?<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">To understand how DNS cache poisoning works, let\u2019s break it down step by step:<\/p>\n\n\n\n<ol class=\"wp-block-list\">\n<li><strong>User Request<\/strong> \u2013 You enter a domain name like <em><strong>example.com<\/strong><\/em> in your browser.<\/li>\n\n\n\n<li><strong>DNS Resolver Check<\/strong> \u2013 Your ISP\u2019s DNS resolver checks if it has the IP cached.<\/li>\n\n\n\n<li><strong>Normal Process<\/strong> \u2013 If cached, the resolver responds with the IP.

What is the difference between DNS cache poisoning and DNS spoofing?<\/strong><\/strong> <p class=\"schema-faq-answer\"><strong>A. <\/strong>DNS cache poisoning is a type of DNS spoofing where the fake response is stored in the cache. Spoofing can be temporary, poisoning lasts until the cache is flushed.<\/p> <\/div> <div class=\"schema-faq-section\" id=\"faq-question-1755944643906\"><strong class=\"schema-faq-question\"><strong>Q. Can flushing DNS cache prevent DNS poisoning?<\/strong><\/strong> <p class=\"schema-faq-answer\"><strong>A. <\/strong>Yes, flushing can remove malicious entries, but it\u2019s not a permanent solution. Prevention via DNSSEC is better.<\/p> <\/div> <div class=\"schema-faq-section\" id=\"faq-question-1755944652936\"><strong class=\"schema-faq-question\"><strong>Q. Does antivirus protect against DNS cache poisoning?<\/strong><\/strong> <p class=\"schema-faq-answer\"><strong>A. <\/strong>Not directly. Antivirus can block malware delivered via poisoned sites, but DNSSEC and secure resolvers are the real defense.<\/p> <\/div> <div class=\"schema-faq-section\" id=\"faq-question-1755944848310\"><strong class=\"schema-faq-question\"><strong>Q. How common is DNS cache poisoning today?<\/strong><\/strong> <p class=\"schema-faq-answer\"><strong>A. <\/strong>While less common than phishing, it still poses a serious threat due to unprotected DNS servers.<\/p> <\/div> <\/div>\n\n\n\n<p class=\"wp-block-paragraph\" style=\"font-size:23px\"><strong>Conclusion:)<\/strong><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">DNS cache poisoning is one of the most dangerous but lesser-known cyber threats. By exploiting the weaknesses in DNS, attackers can silently redirect thousands of users to malicious websites. This not only causes <strong>financial losses and data breaches<\/strong> but also destroys brand trust.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The good news is\u2014<strong>with DNSSEC, secure resolvers, and proper monitoring\u2014you can prevent most DNS poisoning attempts<\/strong>.
