The creation of the Domain Name System (DNS) in the early 1980s was a big achievement. Its design considered a vast functionality, but security was not a priority almost four decades ago. The problem is that criminals knew it, and soon they took advantage of this weak point. Criminals developed different attacks using the DNS, like the dangerous DNS spoofing.
What is DNS spoofing?
DNS spoofing is a hacking attack. Criminals enter spoofed or forged entries or DNS records into the cache of a recursive server to respond to DNS users’ queries with a spoofed record, for instance, a forged IP address. This way, legit traffic is maliciously directed to dangerous destinations (forged websites). Once there, users can be pushed to type sensitive data (passwords, bank card details, etc.) for criminals to take advantage of later.
