A DNS attack uses the Domain Name System, or DNS, to cause problems in a network. Hackers who are looking to steal data from customers or spread malware will often use it to target websites and business organizations.
DNS attacks are a common way of bypassing firewalls and other security measures. They can also be used to download malware and exfiltrate data. Consequently, it is vital that all network traffic be monitored and that DNS servers be protected.
What is DNS Attacks?
DNS attacks attempt to stop a DNS from fulfilling legitimate requests. There are many different types of DNS attack and several ways to defend them.
The most common DNS-based attack is a Denial-of Service attack. In this case, network users are unable to access certain websites or services. This type of attack is typically performed using a botnet that sends massive amounts of DNS requests to a target IP address, overloading the targeted server and preventing it from responding to normal traffic.
Another type of DNS attack involves changing the IP address of a targeted machine, which will make it impossible for other machines on the same network to connect to that device. This type is typically carried out by a cybercriminal who has gained MAC level control over the target's computer network.
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. Instead, these queries are for non-existent domains or subdomains. This makes the DNS servers spend a lot of resources searching for these non-existent subdomains.
The third type involves sending synchronize (SYN), messages in large quantities to the target. This is done faster than it can reply. The result is a large number of half-open connection, which ultimately overloads the server causing it to crash.
The attacks can be performed in a number of ways, such as sending bursts SYN/ACK messages to a targeted server or spoofing a udp Port 53 to poison the cache and redirect DNS clients towards rogue websites. The udp Port 53 attack is especially dangerous as the attacker needs only to spoof a 16 bit transaction ID in order for the DNS cache to be poisoned.
It is important to note that a dns attack can be extremely costly. In the IDC 2020 Global DNS Threat Report the financial services industry was cited as most vulnerable to DNS attack.
In addition to stealing data, these threats can damage reputations, lead to a loss of customers and cause downtime for cloud services. Additionally, these attacks are typically not reversible, so they should be prevented at all costs.
A DNS attack is not only a threat to information theft but can also cause network outages that affect millions of users. These attacks occur more often when a victim's DNS infrastructure has not been properly protected.
