DNS SPOOFING
DNS spoofing, also known as DNS cache poisoning, is a technique used to manipulate the Domain Name System (DNS) to redirect users to malicious or unauthorized websites. It involves modifying the DNS cache of a DNS server or the local DNS cache on a user's device to associate incorrect IP addresses with domain names.
Here's an example to help illustrate DNS spoofing:
Let's say there's a legitimate website called "www.example.com" with the IP address 192.168.0.100. When a user tries to access "www.example.com," their device queries a DNS server to resolve the domain name to its corresponding IP address. The DNS server responds with the correct IP address of 192.168.0.100, and the user's device connects to the legitimate website.
Now, if an attacker successfully performs DNS spoofing, they can manipulate the DNS cache to associate a different IP address, such as 192.168.0.200, with the domain name "www.example.com." When the user's device queries the DNS server again, the spoofed response is sent, providing the malicious IP address instead of the legitimate one.
As a result, when the user tries to access "www.example.com," their device connects to the IP address 192.168.0.200, which may be a malicious website designed to mimic the legitimate site. The attacker can then potentially gather sensitive information, perform phishing attacks, or carry out other malicious activities.
It's important to note that DNS spoofing is illegal and unethical. This example is provided for educational purposes only to increase awareness about the technique. It's crucial to protect your network and devices from such attacks by implementing security measures and keeping your systems updated.
