What is a DNS Attack?

By Dylan Smith 16 July, 2023 2 mins read

A DNS attack is an example of a cyberattack that makes use of the Domain Name System in order to cause network issues. Hackers often target businesses and websites to steal data or spread malware.

DNS attack can be a very effective way to bypass firewalls and other security tools, and is also commonly used for data exfiltration, including malware downloads. It is crucial to monitor and secure DNS servers.

What is DNS Attacks?

DNS attacks involve an attempt to disable or crash a DNS service, which prevents the server from serving legitimate requests. There are different types and ways of defending against DNS attacks.

Denial-of-Service attacks are the most common DNS attacks. They make it difficult for users to connect to a service or website. This type attacks is often performed by botnets that send massive DNS requests towards a specific IP address. They overload the server, preventing it to respond to normal traffic.

One type of DNS attacks involves changing the IP of the targeted device, making it impossible for any other devices on the network to connect. Hackers who have gained MAC control of the target network are usually responsible for this type of attack.

This type is an attack that involves sending a large amount of queries to a DNS target server. These queries do not pertain to legitimate domain names. In reality, these queries refer to non-existent domains. This makes the DNS servers spend a lot of resources searching for these non-existent subdomains.

Third-type DNS attacks involve sending large amounts of synchronize(SYN), faster than the target can respond. The result is a large number of half-open connection, which ultimately overloads the server causing it to crash.

These attacks can be carried out by a variety of methods, including sending bursts of SYN and ACK messages to the targeted server, or spoofing a udp port 53 in order to poison its cache and redirect DNS clients to rogue sites. The udp port 53 attack is a particularly dangerous one because it only requires the attacker to spoof a 16-bit transaction ID in order to poison the DNS cache.

Note that a DNS attack can be costly. The IDC 2020 Global DNS Threat Report cites financial services firms as the most at risk of DNS attacks.

In addition to stealing your data, these threats may damage your reputation and lead to the loss of customers. They can also cause downtimes in cloud services. In addition, since these attacks are usually not reversible they should be avoided.

A DNS attack is not only a threat to information theft but can also cause network outages that affect millions of users. These attacks are likely to happen when the DNS infrastructure on a targeted site is not protected.
