Examples of such attacks would include WordPress XMLRPC pingback attacks, Apache slowloris, etc. These attacks are tailored to the specified application just to drain the servers’ resources. Layer 7 attacks are sophisticated application based DDoS attacks. However, if the traffic is spoofed, it would also be an ineffective method. IP based firewall rules would be able to put the flood under control. It consume the routers’ resources as the routers will have to process the large amount of UDP packets. UDP is fast and allows a large amount of packets to be sent. Spoofed UDP FloodĪ UDP flood is to flood a server with a large amount of useless UDP packets. TCP Syncookies would be able to put the flood under control. This would consume the servers’ resources and also saturate the bandwidth with useless traffic. Some of the providers that allow packet spoofing are:Ī SYN flood is to flood a server with a large amount of useless TCP Synchronize “Open” traffic. The shady market is a huge opportunity for these providers to explore into as it is quite profitable. While other times, it is intentionally allowed so that the provider would be able to host customers who want to spoof their packets. Sometimes, it is not implemented due to incompetency. Packets can be easily spoofed if the service provider does not implement Access Control List (ACL) and some basic security. Therefore, traditional methods of DDoS protection will not work as effectively. Spoofing of packets will render all IP based firewall rules useless. Tools such as hping3 allows you to do so. Spoofing is to modify the IP packet’s source address to another IP address which they do not own.

In this article, we’ll be focusing on the newer methods of attacking, such as spoofing and application layer (L7) attacks. There are many methods a person can launch a DDoS attack.

In this article, we’ll be diving deeper into the types of attacks and how it can be fended off. In the previous article, IPv6 DDoS is now a threat, we’ve looked at how Distributed Denial of Service (DDoS) in IPv6 has increased significantly.
