Definition Edit

A UDP flood attack is

a type of DoS attack using the User Datagram Protocol (UDP), a sessionless/connectionless computer networking protocol by sending UDP packets to a random port on the victim system. When the victim system receives a UDP packet, it will determine what application is waiting on the destination port. When it realizes that there is no application that is waiting on the port, it will generate an ICMP packet of destination unreachable to the forged source address. If enough UDP packets are delivered to ports on victim, the system will go down.[1]
