Legitimate UDP-based transmissions are used in especially time-sensitive communications, such as those for video playback, gaming applications, and DNS lookups. It speeds up communications by not formally establishing a connection before data is transferred. Unlike the more common Transmission Control Protocol, UDP doesn\u2019t wait for a connection between two computers to be established through a handshake and doesn\u2019t check whether data is properly received by the other party. Instead, it immediately sends data from one machine to another.<\/p>\n<p>UDP flood attacks send extremely high volumes of packets to random or specific ports on the target IP. Such floods can saturate the target\u2019s Internet link or overwhelm internal resources with more packets than they can handle.<\/p>\n<p>Since UDP doesn\u2019t require a handshake, attackers can use it to flood a targeted server with torrents of traffic without first obtaining the server\u2019s permission to begin the transmission. UDP floods typically send large numbers of datagrams to multiple ports on the target system. The target system, in turn, must send an equal number of data packets back to indicate the ports aren\u2019t reachable. Eventually, the target system buckles under the strain, resulting in legitimate traffic being denied.<\/p>\n<\/blockquote>\n<\/div>\n<p> \t<BR><br \/>\n <BR><\/BR><br \/>\n    Bruce Schneier<br \/>\n \t<BR><br \/>\n<BR><\/BR><br \/>\n<a href=\"https:\/\/www.schneier.com\/blog\/archives\/2025\/06\/largest-ddos-attack-to-date.html\">Go to bruce schneier<\/a><br \/>\n \t<BR><br \/>\n <BR><\/BR><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Largest DDoS Attack to Date It was a recently unimaginable 7.3 Tbps: The vast majority of the attack was delivered in the form of User Datagram Protocol packets.
