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 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 therefore vital to monitor all network traffic and protect DNS servers.
What is DNS Attacks?
DNS attacks aim to disrupt, crash or otherwise damage a DNS Server. This prevents it from being able to serve legitimate requests. There are a variety of DNS attacks, and there are a few ways to protect against 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 attack is performed with a Botnet that sends massive DNS queries to a targeted IP, overloading it and preventing normal traffic.
DNS attacks are also used to alter the IP addresses of machines, making them unreachable by other computers on the same network. This type is typically carried out by a cybercriminal who has gained MAC level control over the target's computer network.
This type of attack involves sending large numbers to a DNS server targeted, but they are not for legitimate domain names. These queries are instead for non-existent subdomains or domains. 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 of DNS attacks involves sending massive amounts of synchronize messages (SYNs) to the target faster than they can respond. This leads to a lot half-open connections which overload the server, causing it 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. This udp 53 attack is particularly dangerous because the attacker only needs to spoof 16-bit transaction ID to poison DNS cache.
The cost of a dns hack can be high. 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. These attacks can also be irreversible. They should therefore be avoided.
DNS attacks are not limited to the obvious threat of data theft. They can also be used as a tool to disrupt millions of services and cause widespread network outages. These attacks occur more often when a victim's DNS infrastructure has not been properly protected.
