W32.Axatak [Symantec-2002-082217-5638-99] - password stealing virus with remote access trojan capabilities. 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.

A directory traversal vulnerability was discovered in Enphase Envoy R3.*.* via images/, include/, include/js, or include/css on TCP port 8888.

SANS Internet Storm Center: port 8888

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.

Sitescope also uses port 8888 by default

FortiNet's enterprise UTM client software uses port 8888 udp, apparently to call home to Canada.
by anonymous - 2015-03-25 23:16
privateinternetaccess VPN uses 8888/tcp to test connection speeds to different hosts. See for a long discussion about this.
by anonymous - 2015-10-11 01:23
Freenet uses this as well if you are a node
by anonymous - 2015-12-16 22:52
This is exactly what I needed to hear. Thank you.
by anonymous - 2017-07-19 18:18
AirDroid also uses this port

Also MAMP on macOS uses 8888 by default for Apache.

Visual Studio Code for Jupyter also uses 8888

EpicProxy extension (HTTP Web Proxy) built into Epic Privacy Browser uses TCP 8888 ( )

Getting an error message after installing PW PhishWall in Japanese, translated into English would be TCP port 8888 usage allocation failed. Launch the PhishWall client as another user with administrator privileges. makes no sense as the user has administrator privileges
by FernandoN - 2022-07-29 09:47
I have the same issue as Roberto. I live in Japan too. When you make on-line transactions with a Japan Post bank account they ask you to install this "PhishWall" extension. You have to have adminintrator priviledges to install it. But from now on, you have to enter an admin password EVERY TIME you boot the system. Very annoying!

VRRP-E by Brocade also uses multicast udp port 8888
