What is DNS Spoofing & Link Redirection – Safe from It in 2022

Domain Name Server (DNS) spoofing, also known as DNS cache poisoning(DNS spoofing), is a technique used in attacks to cause online traffic to be diverted to a fake website that closely matches the one to which it was originally sent.

The DNS attack often takes place in a public Wi-Fi setting, but it can happen anywhere an attacker has access to the ARP (Address Resolution Protocol) tables and can trick targeted user devices into using the attacker-controlled system as the server for a particular website.

It can fool users into installing malware on their devices or disclosing personal information. It’s the initial stage of a complex phishing attack on public Wi-Fi.

What is a DNS Server?

The DNS lookup procedure is carried out by domain name system servers (DNS servers), a grouping of four different server types.

Resolving name servers, root name servers, top-level domain (TLD) name servers, and authoritative name servers are some of them. We’ll limit the details to the resolver server for the sake of simplicity.

DNS Lookup

In a broad sense, a DNS lookup is the procedure used to obtain a DNS record from a DNS server. This is called a “lookup” because it is similar to looking up a phone number in a phone book. People’s email addresses and domain names must be converted into meaningful numerical addresses for interconnected computers, servers, and smartphones to function properly. This operation is carried out using a DNS lookup.

How DNS Lookup Works

This is how a DNS lookup function when you look up a website by its domain name.

  1. Your operating system (OS) and web browser make an effort to remember the IP address associated with the domain name. The IP address can be retrieved from the computer’s internal memory cache if it was previously visited.
  2. If neither component is aware of the target IP address, the process goes on.
  3. For the IP address, the OS asks the resolving name server. To find the correct IP for the domain, a series of servers are searched using this query.
  4. In the end, the resolver will discover the IP address and provide it to the OS, which then sends it back to the web browser.

The essential infrastructure that underpins the internet is the DNS lookup procedure. Sadly, DNS flaws can be used by Cyber expires, so you must be cautious of such redirects. Let’s go over DNS spoofing’s definition and operation for your benefit.

DNS Poisoning and DNS Spoofing

DNS cache poisoning, sometimes referred to as DNS spoofing, is a technique for hacking computers in which traffic is purposefully redirected to a victim’s computer using corrupted cached data.

A target is essentially all that is required for a DNS spoofing attack. This might be an “Authoritative Name Server” (easily found by running a WHOIS on any domain on the Internet) and a security vulnerability on the system supporting that DNS cache.


Anyone can start redirecting traffic from “yahoo.com” (or any other chosen host) to any other location on the internet by simply adjusting the DNS server’s cache (or even more devious, the local LAN).

The main issue with this is that providing “spoofed” or “hijacked” answers via the widespread use of DNS can result in a variety of problems, including phishing attempts, SPAM, password leaks, and social engineering attacks, political turmoil, and more.

It can make practically everyone in its path miserable, not just the intended victim. the positive news Even though these weaknesses are widely acknowledged, an astute network and/or systems architect or engineer can take certain steps to keep the peasantry perpetually “rejoicing” rather than “revolting”.

DNS Spoofing or Cache Poisoning Attacks

These are some of the more typical DNS spoofing techniques among the many available:

MITM Duping:

when a hacker infects both your web browser and DNS server by getting between them. A tool is utilized to simultaneously poison the DNS server and your local device’s cache.

A malicious website hosted on the attacker’s local server is redirected as a result.

DNS Hijacking

The most general word used here is DNS hijacking, which typically refers to the other two methods. DNS hijacking is the term for any attack that deceives the end user into believing they are dealing with an authentic domain name when they are communicating with an attacker-created domain name or IP address, Another name for this is DNS Redirection.

DNS Poisoning

DNS poisoning is a type of website spoofing in which hackers divert legitimate traffic to a fake one. Accessing confidential information on a device or in the slowed web traffic flow is made simple by DNS poisoning.

Link Redirection Through DNS Spoofing:

We shall take use of the Domain Name Service in this hack (DNS). As you may be aware, DNS is used to resolve domain names or to translate a domain name like wonderhowto.com into an IP address, such as

We might very easily send someone seeking a domain name like bankofamerica.com to our malicious website and steal their credentials if we can interfere with this protocol.

How does Link Redirection work?

  • Go to Applications > Kali Linux > Sniffing > Network Sniffers
  • Open Dnsspoof
  • Set Up for Sniffing
  • Flush the DNS Cache
  • Create Hosts File
  • Create a New BOA Webpage
  • Start the Apache Web Server
  • Start Dnsspoof
  • Navigate to BOA from Windows 7

Now, everyone using the local area network will land on our website instead of the Bank of America website when they try to access it. As you might expect, DNS spoof allows us to cause all sorts of mayhem on a LAN.
