Port used by some proxy servers. Common web proxy server ports: 8080, 80, 3128, 6588
Officiall assignment: Active API Server Port
Trojans and backdoors that use this port: Masters Paradise, Reverse WWW Tunnel Backdoor, RingZero
Mydoom.B (01.28.2004) - mass-mailing worm that opens a backdoor into the system. The backdoor makes use of TCP ports 80, 1080, 3128, 8080, and 10080.
W32.HLLW.Deadhat (2004.02.06) - a worm with backdoor capabilities. It attempts to uninstall the W32.Mydoom.A@mm and W32.Mydoom.B@mm worms, and then it spreads to other systems infected with Mydoom. Also, it spreads through the Soulseek file-sharing program.
Multiple buffer overflows in Thomas Hauck Jana Server allow remote attackers to cause a denial of service and possibly execute arbitrary code via an HTTP GET request with a long major version number, an HTTP GET request to the HTTP proxy on port 3128 with a long major version number, a long OK reply from a POP3 server, and a long SMTP server response.

TCP ports use the Transmission Control Protocol. TCP is the most commonly used protocol
on the Internet and any TCP/IP network. Whereas the IP protocol deals only with packets, TCP enables two hosts
to establish a connection and exchange streams of data. TCP guarantees delivery of data
and that packets will be delivered in the same order in which they were sent.
Guaranteed communication/delivery is the key difference between TCP and UDP.
UDP ports use the Datagram Protocol, a communications protocol for the Internet network,
transport, and session layers. Like TCP (Transmission Control Protocol),
UDP is used with IP (the Internet Protocol) and makes possible the transmission of datagrams
from one computer to applications on another computer, but unlike TCP, UDP is connectionless
and does not guarantee reliable communication; it's up to the application that received
the message to process any errors and verify correct delivery. UDP is often used with time-sensitive
applications, such as audio/video streaming, where dropping some packets is preferable to waiting for delayed data.
