The Domain Name System (DNS) is often compared to the phonebook of the internet it translates domain names into IP addresses so users can access websites easily. But what if this phonebook was tampered with? Welcome to the world of DNS Spoofing, a stealthy cyberattack that can reroute your online traffic without your knowledge.
This blog explores what DNS Spoofing is, how attackers exploit it, and how organizations can stay a step ahead with support from experts like CyRAACS.
What Is DNS Spoofing
DNS Spoofing, also known as DNS cache poisoning, occurs when a threat actor injects malicious DNS entries into a DNS resolver’s cache. This manipulates where users are directed, leading them to fake websites designed to steal data, install malware, or intercept communications while the browser still displays the legitimate URL.
Real-World Example
Picture a user trying to visit their bank’s website by entering www.mysecurebank.com. Unknown to them, a threat actor has poisoned the DNS cache. Instead of the legitimate site, they are routed to a fraudulent replica hosted by the attacker. The victim logs in as usual, except this time, their credentials go straight to the attacker. The site looks perfect, but the damage is real.
That is, DNS spoofing silent, deceptive, and highly effective.
Threats Associated with DNS Spoofing
- Credential theft
- Malware delivery
- Man in the middle attacks
- Brand and reputation damage
How Attackers Execute DNS Spoofing
- Cache poisoning
- Man in the middle interception
- Exploiting weak DNS infrastructure
Prevention Best Practices
- Enable DNSSEC for authentication
