DNS amplifications are one of the most potent DDoS attacks. They can be used to bring an entire system down. The attacker will manipulate DNS to flood a victim with large numbers of UDP packages, which can either be amplified into smaller packets or fragmented.
The attack uses IP spoofing and open recursion in conjunction with amplification, to send an endless stream of queries towards DNS servers vulnerable to this kind of traffic. This can be done by using a botnet of infected computers, which produce an immense amount of queries that are then sent to targeted DNS servers with the use of an amplification record.
There are several ways to defend against these amplification attacks. Among the most effective methods are securing open network services, such as DNS and NTP, and limiting the number of open network servers that can accept queries. These measures can help reduce the threat of DNS amplifying attacks that could cause a denial of service attack to other services and systems on the network.
An Amplified DNS Flux is a common way to increase DNS DDoS by taking advantage of open DNS server infrastructure. In this attack, the attacker first sends small DNS queries with a spoofed IP address to open DNS servers that are susceptible to the attack. DNS resolvers send the request back to the victim with a much larger response than the original request.
This is a reflection of the attacker's intent, and allows them to send large volumes of traffic without being detected. This DDoS attack is different from others because it uses an amplification protocol that does not use TCP. The protocol can handle large traffic volumes.
UDP communication is efficient, but there are drawbacks. TCP is a three way handshake which means that most spoof TCP attacks will not work because the TCP/IP can efficiently send RSTs (reset) to any unexpected TCP Handshake Requests.
Amplification of this kind can lead to packets fragmenting into smaller pieces, which makes it harder to detect the attack. Deploying a firewall to protect your network from these types of attacks can help prevent these issues.
There are several other techniques that can be deployed to protect against these kinds of attacks, including rate limiting, port limiting and threat intelligence. These can help to limit the number of open recursive DNS servers that can accept traffic and can also help to clean up any malicious TCP/UDP links that are being sent across your network.
Using common tools to monitor network throughput, such as SNMP, netflow and ping can help identify amplification attacks well before they are too late. It is even more important if you are monitoring your network in real-time.
