DNS spoofing – The Internet danger for every business

DNS spoofing sure sounds spooky. It is one of the Internet dangers that lurks in the darkness and threatens every business. Is there a way to stay safe? Let us show you.

What is DNS spoofing?

DNS spoofing is a DNS cyber attack that aims to redirect the DNS clients’ traffic to a fake site, with which the bad actors attempt to steal clients’ personal data (bank accounts, emails, personal information, and more.). The fake site looks just like the real sites they copied. This is why many people get confused and provide their data.

Imagine if you type “amazon.com” and your browser loads a page that looks just like the real one but is a fake copy. Then, you order something, provide your bank card information, and at that moment, the bad actors have your data.

DNS spoofing can be performed in a few different ways.

Poisoned cache of a DNS resolver server. The bad actors hack a resolver server and, with the access they have, they modify the DNS records. Then, they redirect the traffic to a fake site.

Man-in-the-middle. The bad actors can put another resolver between your device and your local DNS resolver. The resolver will perform the domain resolution, sending you directly to the fake site.

Hacked DNS authoritative server. Cybercriminals can also directly hack and edit the records inside your authoritative server. It could be harder, but possible.

Why is DNS spoofing a danger for every business?

The bad actors can steal the traffic from your site and redirect it to their fake site. You can lose potential clients because of it.

Cybercriminals can steal your clients’ data. Unfortunately, the problem is also yours because the clients probably won’t know they are on a fake site controlled by criminals, and they will blame you for any data stolen.

The traffic inside your office can be redirected too. That way, your employees can share sensitive information about your business with the bad actors. That can lead to many problems.

DNS spoofing can damage your reputation overall. After that, it could be very hard to clean it.

Can you protect your business from DNS spoofing?

DMARC can secure your communication. It uses both SPF and DKIM to verify the sender’s domain and encrypt the email communication. It also provides valuable feedback to see if somebody is trying to send emails on your domain’s behalf.

DNSSEC can provide a way to authenticate the domain name. It is a group of security extensions that secures the communication between clients and DNS servers with encryption.

VPN can help keeping you away from man-in-the-middle attacks. It creates a safe tunnel between your device and the VPN provider’s server, making it a good option for public Wi-Fi networks and office work.


Now you know. DNS spoofing is a real danger, but your business has protection methods. Use DNSSEC, DMARC, and VPN, and keep your business and your clients safe.

5 Critical Internet Terms You Need To Know

The topic of our article is the most basic Internet terms and their definitions. To begin with, the Internet is a collection of decentralized networks connected by a system of protocols referred to as TCP/IP. Therefore, the more extensive network enables the communication between computer networks operated by businesses, governments, universities, and other organizations worldwide. We will also define some basic phrases used on the Internet to help you understand this. So let’s start.

Web Browser

The first Internet terms from our list are web browsers. Why are they essential? Many individuals mistakenly believe that a web browser serves as a search engine, but in reality, a browser is computer software that facilitates access to the World Wide Web. Every web page, image, and video on the Internet has a particular Uniform Resource Locator (URL), which enables the browser to recognize the resource and download it from the web server. This is how browsers function. In conclusion, it is client software because it operates on a user’s computer or mobile device and communicates with the webserver to obtain the information the user has requested. In addition, the ability to store downloaded files, music, and movies via an integrated FTP client is also available in web browsers.

IP address

The Internet’s anchors are its IP addresses. They support your entire digital life and connect you to the Internet. Furthermore, IP address stands for Internet Protocol address. It is a set of numbers that are given to each device linked to the Internet or a computer network. For instance, it is This example is an IPv4 address, although IPv6 addresses are also possible.

Domain Name System (DNS) 

Since names are more accessible for people to remember than numbers, the Domain Name System (DNS) is best recognized for connecting domain names (hostnames) with IP addresses. One of the most crucial foundations of the Internet as we know it today, the Domain Name System, plays a significant part in facilitating our ability to use it conveniently. Additionally, because DNS’s primary function is to link domain names and IP addresses rather than to provide security, it is vulnerable to several cyber threats like DDoS attacks. As a result, implementing additional features like DNSSEC, DDoS Protected DNS, DNS Failover, DNS Monitoring, etc., is frequently necessary.

Domain name 

The exclusive address for a website is its domain name. This is the address at which Internet visitors can access your website. To identify and map websites and other Internet Protocol (IP) resources, the Domain Name System (DNS) uses host names or domain names. On the Internet, machines are located and identified using their domain names. They are unique and cannot be used by another website. For example, think about internet-eireann.ie


A TLD is a domain extension that refers to the letters of a domain name that come after the dot. In our example internet-eireann.ie this is .ie. Other popular examples of a TLD include, .com, .net, .org., .gov, .edu, etc. Additionally, there are other TLD types, including:

  • gTLD – It stands for Generic Top-level Domains and popular examples are .org, .com. and .net
  • sTLD – It abbreviation stands for Sponsored Top-level Domains. And the most usable sTLD’s are .edu and .gov.
  • ccTLD – It means Country Code Top-level Domains and the most common among them are: .fr, .uk, .usa, .ie, etc.

TLDs are an essential part of a company’s URL. With them, you may develop client loyalty and target a particular audience.


Congratulations! You are one step closer to the fundamentals of the Internet. You now know all the necessary Internet terms. Additionally, you will now be more aware of what the various components signify when you browse the Internet!
