Booter affect the DNS flood. The DNS server are the phonebooks meant for the internet. It refers to the path through the internet devices where they get to look up for certain web servers so that they can be in a position to access the content on the internet. A DNS flood is a DDoS type that attacker floods a particular DNS domain server to attempt in disrupting the resolution of the DNS for that particular domain.
If it happens that a user ends up being unable to get the phonebook, then the address might not be able to get looked up to make the necessary call for a certain resources. When the DNS resolution is disrupted for that particular resource.
When the DNS resolution is disrupted, then a DNS flood attack will end up compromising a website, web application, or API ability in responding to the traffic that is legitimate. It might hard to distinguish normal heavy traffic from the DNS flood attacks as the large volume of the traffic does come from various locations, querying for the exact records on the domain that mimick the traffic that is legitimate.
The way the DNS flood attack works
The function of the DNS is normally to translate between website names that are easy to remember with the ones which are hard to remember. It means that, the successful attack of the DNS infrastructure ends up making the internet to be unusable for many people. The DNS flood attacks are what constitutes the new type of attack that are DNS-based which are proliferated with the rise of the bandwidth that is high of the internet of things – IOT botnet such as Mirai.
The DNS flood attacks utilize the high bandwidth connection that is on the IP cameras, the DVR boxes plus other devices of IoT to overwhelm the DNS servers directly that belong to major providers. The request volumes from the other devices of IoT do overwhelm the service providers of DNS, preventing legitimate users from having to access the DNS servers
The DNS flood attacks tend to differ from the attacks of the DNS amplification. The DNS amplification attacks unlike the DNS floods, amplify and reflect off the traffic of the DNS servers which is unsecured to hide the attack that originally happened, increasing effectiveness.
The DNS amplification attacks utilize the devices that have smaller bandwidth connection for making various requests to the DNS servers that are unsecure. The devices do make some small requests for the large DNS records but when the requests are made, the attacks ensure to forge the address for return to be that of the victim. It is the amplification which tend to allow for the attackers to take out large targets with few attack resources.
Mitigating a DNS flood attack
The DNS floods are a representation of change from the traditional amplification that is based on the method of attack which is utilized. With high bandwidth botnets which is easily accessible, attackers can go ahead and target larger organizations.
