DNS Spoofing Guide

What is DNS Spoofing?

DNS Spoofing is a type of cyberattack where an attacker corrupts the Domain Name System (DNS) to redirect users to malicious websites. By poisoning the DNS cache, the attacker can trick users into visiting fake websites designed to steal sensitive information.

How DNS Spoofing Works

• Cache Poisoning: The attacker injects fake DNS records into the DNS cache.
• Redirection: Users are redirected to malicious websites instead of the intended ones.
• Data Theft: The attacker captures sensitive information like login credentials or credit card details.

Here’s how you can perform DNS Spoofing (for educational purposes only):

1. Choose a Tool: Select a tool like Ettercap or Bettercap.
2. Set Up the Attack: Position yourself between the victim and the DNS server.
3. Inject Fake Records: Use the tool to inject fake DNS records into the cache.

How to Protect Yourself

To protect yourself from DNS Spoofing, follow these steps:

• Use DNSSEC: Deploy DNS Security Extensions (DNSSEC) to validate DNS responses.
• Monitor DNS Traffic: Continuously monitor for unusual DNS activity.
• Use HTTPS: Always use HTTPS to encrypt your traffic.
• Educate Users: Train employees to recognize phishing and suspicious activity.
