Dns attacks are cyberattacks that use the Domain Name System (DNS), to cause issues with networks. It is often used to target business organizations and websites by hackers who want to steal customer data or spread malware.
DNS attacks are a common way of bypassing firewalls and other security measures. They can also be used to download malware and exfiltrate data. It is essential to monitor all traffic on the network and to 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 several different types of DNS attacks and a number of ways to defend against them.
The most common type of DNS attack is a denial-of-service attack, which makes it difficult for network users to access a website or service. This type attack is performed with a Botnet that sends massive DNS queries to a targeted IP, overloading it and preventing 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.
This type of attack is performed by sending large numbers of queries to a targeted DNS server, but not for a legitimate domain name. Instead, these queries are for non-existent domains or subdomains. This causes the DNS server to spend a significant amount of resources looking up these non-existing domains, which can be very inefficient and result in poor network performance.
The third type involves sending synchronize (SYN), messages in large quantities to the target. This is done faster than it can reply. This leads to a lot half-open connections which overload the server, causing it crash.
These attacks can take place in a few different ways. One of them is to send bursts SYN/ACK and spoof a udp-port 53. This will poison its DNS cache and cause it to redirect clients to rogue web sites. 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.
Note that a DNS attack can be costly. According to the IDC 2020 Global DNS Threat Report financial services companies are the most vulnerable.
Apart from stealing data, this threat can cause reputational damage, loss of customers, and downtimes for cloud services. These attacks are also usually irreversible and should be avoided 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 can be more common if a target's infrastructure for DNS is not protected.
