Definition of DNS tunneling attack

DNS tunneling attack is a type of cybercrime. The goal is a domain name system attack, as maybe its name suggests. So, it operates in a straightforward manner. However, DNS requests and responses frequently contain malicious material that is encoded by other programs or protocols. This provides an unnoticed command and control channel for attackers as well as a means of data theft.

History of DNS tunneling

Stages of a DNS tunneling attack

The stages of a DNS tunneling attack are as follows:

1. A hacker registers a domain and directs it to a server that belongs to him. Then it has the malware for tunneling installed on it.

2. The hacker infects the device with malware, breaks through the victim’s firewall, and abducts the affected device or the entire network.

The function of a Private DNS server

A Private DNS server appears to be something unique, as the name suggests. It creates a connection between your network and the Domain Name System server, preventing unauthorized access to data. These DNS networks are separate from the Public DNS. Think of it as a little private library with a selection of books. There are benefits and drawbacks to this. You will indeed be unable to read several genres of literature. However, there is one benefit: since your library is private, no one will know what you are reading.

Additionally, DNS over TLS (Transport Layer Security) or DNS over HTTPS (Hypertext Transfer Protocol Secure) are terms we use to refer to Private. This is due to the fact that all DNS queries are encrypted when using DoT (DNS over TLS) or DoH (DNS over HTTPS). This makes it much harder for nefarious third parties to watch your online behavior.

Anycast DNS is a fantastic service that might benefit your company. It allows you to surf the web considerably more quickly and efficiently. So, let’s dig a little deeper into that.

What does Anycast DNS mean?

Anycast DNS is a routing mechanism that employs a simple trick: all instances have the same IP address. Therefore, you’ll have a network of Anycast DNS servers with the same IP address if you use it. Yes, this is doable, and there is no difficulty with the network. The benefit is that anybody who searches your domain name will obtain the same IP address, regardless of where they are in the world. The request will then proceed to this IP address, and because it is the same IP address, it will receive a response from the nearest Anycast DNS server. This saves time and ensures redundancy since if one server goes down, the request will travel a little further and receive a response from the next Anycast DNS server on the network.
