DNS Spoofing
An attack that alters DNS records to redirect users to malicious websites.
Understanding DNS Spoofing
DNS works as the internet’s phonebook, translating domain names (e.g., example.com) into IP addresses. DNS spoofing occurs when an attacker:
Poisons DNS Caches – Injects false DNS records into a resolver’s cache.
Performs Man-in-the-Middle (MITM) Attacks – Intercepts and alters DNS queries.
Uses Rogue DNS Servers – Directs users to malicious domains by changing network configurations.
Key Features of DNS Spoofing
Invisible to Users – Victims are unaware they are being redirected.
Exploits DNS Weaknesses – Takes advantage of unauthenticated DNS responses.
Widely Used in Cybercrime – Common in phishing, malware distribution, and ransomware campaigns.
Best Practices to Mitigate DNS Spoofing
Implement DNSSEC (DNS Security Extensions) – Adds cryptographic signatures to DNS responses.
Use Secure DNS Resolvers – Services like Google DNS (8.8.8.8) or Cloudflare DNS (1.1.1.1).
Enable Network Encryption – Use VPNs and TLS encryption to protect DNS queries.
