Detecting DNS Tunneling

By Dylan Smith 27 August, 2023 2 mins read

DNS tunneling is the technique used by hackers to hide malicious information within DNS queries and send them to a server controlled by the attacker. This method can be used to bypass firewalls, and other security measures.

You can detect DNS tunneling using several techniques. This includes payload analysis as well as traffic analysis.

One of the first steps in detecting a DNS tunneling attack is to make sure that you are using a strong antivirus/antimalware program and that your security system is performing deep scans of all traffic coming into your network. This will enable you to identify any suspicious activities that are occurring before it is too much.

There are also detection tools that will look at the size of the DNS requests and responses and see if they are unusually large for normal usage. DNS tunneling usually involves a packet header with extra bytes.

Some of these programs will capture DNS traffic, and store it to be analyzed later. They can then compare it to the average amount of traffic for that particular domain and find any anomalies.

This is particularly useful if your goal is to track the amount of data that comes in and goes out of your system, or peaks in transmission.

It's difficult to detect DNS tunneling and it takes sophisticated techniques. You need to have a good set of detection tools that will analyze all types of traffic, including DNS queries and responses.

The first step is to ensure that you are utilizing an advanced antivirus/antimalware program that will perform a deep scan of all of the traffic going into and out of your network. This will be essential if you are trying to detect any type of attack that is occurring.

You will also need to have a set of detection tools that will monitor your traffic for any unusual behaviors, such as spikes in the data being sent or any out of the ordinary destinations for that traffic. You can then identify suspicious activities before they become too late.

You will want to check any hostnames sent and received that look strange. These can be used for determining if the attacker has chosen a DNS record that isn't commonly used or if unusual character sets are being used.

As an alternative to the methods described above, you can conduct a statistical study of the data that is being sent or received. You can do this by analyzing the number of characters in the domain name, and the amount of data being sent via the DNS protocol.
