Multi-vector Attacks are the most complex forms of DDoS attack. Instead of utilizing a single method, a combination of tools and strategies are used to overwhelm the target and take it offline. Often times, multi-vector attacks will target specific applications on the target server, as well as, flood the target with a large volume of malicious traffic. These types of DDoS attacks are the most difficult to mitigate because the attack come in different forms and target different resources simultaneously.
