2002 tcp trojans Port used by LogMeIn (also uses ports 80 and 443 TCP)

W32.Beagle.AX@mm [Symantec-2004-111612-2714-99] (2004.11.15) - mass-mailing worm, also spreads through file-sharing networks. Affects all current Windows versions. The worm opens a backdoor on port 2002/tcp, allowing the machine to be used as an open email relay. Also uses port 80 to contact "".

Backdoor.Singu.C [Symantec-2006-112113-2825-99] (2006.11.21) - a trojan horse that logs keystrokes and opens a back door on the compromised computer.

The CSAdmin web administration interface for Cisco Secure Access Control Server (ACS) 3.2(2) build 15 allows remote attackers to cause a denial of service (hang) via a flood of TCP connections to port 2002.

2002 udp worm-linux 2002 UDP used by

Linux.Slapper.Worm [Symantec-2002-091311-5851-99] (2002.09.13) - family of worms that use an "OpenSSL buffer overflow exploit [CVE-2002-0656] to run a shell on a remote computer. Targets vulnerable Apache Web servers under various Linux distributions. The worm has distributed denial of service (DDoS) attack capabilities. It spreads by exploiting ports 80/tcp and 443/tcp. Opens backdoors on the following ports: 2002/udp (.A variant), 1978/udp (.B variant), 4156/udp and 1052/tcp periodically (.C variant).

SANS Internet Storm Center: port 2002

Port numbers in computer networking represent communication endpoints. Ports are unsigned 16-bit integers (0-65535) that identify a specific process, or network service. IANA is responsible for internet protocol resources, including the registration of commonly used port numbers for well-known internet services.
Well Known Ports: 0 through 1023.
Registered Ports: 1024 through 49151.
Dynamic/Private : 49152 through 65535.

TCP ports use the Transmission Control Protocol, the most commonly used protocol on the Internet and any TCP/IP network. 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. Like TCP, UDP is used in combination with IP (the Internet Protocol) and facilitates 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 and realtime gaming, where dropping some packets is preferable to waiting for delayed data.

When troubleshooting unknown open ports, it is useful to find exactly what services/processes are listening to them. This can be accomplished in both Windows command prompt and Linux variants using the "netstat -aon" command. We also recommend runnig multiple anti-virus/anti-malware scans to rule out the possibility of active malicious software. For more detailed and personalized help please use our forums.
