| 3000 | tcp | various | AdGuard Home Web Interface Ruby on Rails applications default port NodeJS MDaemon WorldClient Rocket Chat NodeJS Calista IP Phone (TCP/UDP) Viewgate Classic DVR Grafana (default http port) GOGS (self-hosted GIT service) Homeworld, Destroyer Command (TCP/UDP), Theef, Silent Hunter II (TCP/UDP), Active Worlds File Transfer (TCP/UDP), Miralix License server Malware that uses this port: Remote Shutdown, InetSpy, Alt-N Technologies MDaemon 3.5.4 allows a remote attacker to create a denial of service via the URL request of a MS-DOS device (such as GET /aux) to the Worldclient service at port 3000, or the Webconfig service at port 3001. WDaemon 9.5.4 allows remote attackers to access the /WorldClient.dll URI on TCP port 3000, which has unknown impact. NOTE: The researcher reports that the vendor response was "this is not a security bug." Multiple stack-based buffer overflows in pdmwService.exe in SolidWorks Workgroup PDM 2014 SP2 allow remote attackers to execute arbitrary code via a long string in a opcode to port 3000. Backdoor.Win32.Buterat.cxq / Insecure Permissions EoP - this malware creates an insecure dir under c:\ drive named "process", where it drops a random named executable and later moves it to C:\Users\[VICTIM]\AppData\Local\Temp where it sends SYN packets to TCP port 3000. The process dir grants change (C) permissions to the authenticated users group. Cloud9 Integrated Development Environment server (IANA official) | SG |
| 3000 | udp | btsync | BitTorrent Sync (BTsync) uses port 3000 UDP to connect to torrent trackers. It also uses another configurable random UDP listen port (and/or UPnP). Distributed Interactive Simulation (DIS) default port (unofficial) Calista IP Phone, VidPhone Trend Micro Antivirus products may use port 3000 UDP to communicate with their servers. Some games use this port: Homeworld, Destroyer Command (TCP/UDP), Theef, Silent Hunter II (TCP/UDP), Active Worlds File Transfer (TCP/UDP) | SG |

SANS ISC: port 3000
Notes:
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.

Trend Micro Server Protect for NT (and more recent A/V products from Trend) use udp 3000 broadcasts to locate the local IS server for that product. This is totally expected and NOT malicious traffic.
