Dark IRC (trojan)
W32.Axatak - password stealing virus with remote access trojan capabilities, 08.2002. Affects all current Windows versions, uses ports 8888 and 8889.

Autodesk VRED Professional 2014 contains an unauthenticated remote code execution vulnerability. Autodesk VRED Professional 2014 contains an integrated web server that binds to port tcp/8888 which is accessible remotely. It has been reported that this web server gives access to a Python API which provides users with a vast amount of libraries which could allow an attacker to execute operating system commands. Through this API, Python code can be executed on the target system, the output is returned in the web server response. By importing the Python "os" library, arbitrary operating system commands can be executed on the target system with the privileges of the user running VRED Professional 2014.
References: [CVE-2014-2967]

An issue was discovered in CloudMe 1.11.0. An unauthenticated local attacker that can connect to the "CloudMe Sync" client application listening on port 8888 can send a malicious payload causing a buffer overflow condition. This will result in code execution, as demonstrated by a TCP reverse shell, or a crash. NOTE: this vulnerability exists because of an incomplete fix for CVE-2018-6892.

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.

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.

FortiNet's enterprise UTM client software uses port 8888 udp, apparently to call home to Canada.

privateinternetaccess VPN uses 8888/tcp to test connection speeds to different hosts. See for a long discussion about this.

Freenet uses this as well if you are a node

This is exactly what I needed to hear. Thank you.
