A DNS attack is an example of a cyberattack that makes use of the Domain Name System in order to cause network issues. It is used by hackers to target business websites and organizations.
A DNS attack is a powerful way to bypass firewalls, other security tools and download malware. It is therefore vital to monitor all network traffic and protect DNS servers.
What is DNS Attacks?
DNS attacks attempt to stop a DNS from fulfilling legitimate requests. DNS attacks come in many forms and there are multiple ways to defend yourself against them.
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 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 attack is often carried out when a hacker has gained MAC access on the network of their target.
The attacker sends a large number of DNS queries to the targeted server. However, these queries are not for valid domain names. Instead, these queries are for non-existent domains or subdomains. This forces the DNS server spend considerable resources in order to find these nonexistent domains.
The third type of DNS attacks involves sending massive amounts of synchronize messages (SYNs) to the target faster than they can respond. This causes a number of partially open connections that eventually overloads and crashes the server.
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.
Along with stealing data and causing downtime, these threats also can damage a company's reputation, result in a loss of clients, or cause a cloud service to be unavailable. In addition, since these attacks are usually not reversible they should be avoided.
DNS attacks can be used for many other things besides information theft. They can cause massive network failures and disrupt services to millions of people. These attacks are more likely to occur when a target's DNS infrastructure is not properly protected.
