Port(s) Protocol Service Details Source
4444 tcp trojans W32.Blaster.Worm is a widely spread worm that exploits the DCOM RPC vulnerability described in MS Security Bulletin [MS03-026]. The worm allows remote access to an infected computer via ports 4444/tcp and 69/UDP, and spreads through port 135/tcp. To avoid being infected consider closing those ports.

W32.Reidana.A (03.27.2005) - worm that spreads using the MS DCOM RPC vulnerability (MS Security Bulletin [MS03-026]) on port 139. The worm attempts to download and execute a remote file via FTP. Opens TCP port 4444.

Some other trojans using this port: AlexTrojan, CrackDown, Oracle, Prosiak, SwiftRemote, W32.Hllw.Donk.M, W32.mockbot.a.worm

HP Business Service Management (BSM) 9.12 does not properly restrict the uploading of .war files, which allows remote attackers to execute arbitrary JSP code within the JBOSS Application Server component via a crafted request to TCP port 1098, 1099, or 4444.

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.
