Port(s) Protocol Service Details Source
4567 tcp trojans Verizon Actiontec Routers have a web server listening to this port. Verizon FiOS uses it for "secure server connection to automatically monitor/upgrade the router firmware when connected to the FiOS network using a MOTIVE server connection on port 4567". The firmware shipped with Verizon's CPE does not allow port 4567 to be blocked easily.

To possibly block this port, enter the router's admin interface and navigate to:
1. Home -> Advanced-> Protocols-> Add
2. Type any service name, add server ports: protocol -> TCP, source -> any, destination -> single=4567 , then Apply.
3. Navigate to Home -> Security -> Advanced Filtering
4. Input Rule Sets -> Broadband Connection (Ethernet) Rules -> Add

Trojans that use this port: File Nail, BackDoor-IW.

IANA registered for: TRAM
4567 udp applications The agent in Bradford Network Sentry before 5.3.3 does not require authentication for messages, which allows remote attackers to trigger the display of arbitrary text on a workstation via a crafted packet to UDP port 4567, as demonstrated by a replay attack.

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.

Sinatra.rb applications use port 4567 by default.

I have no idea how to fix this, a uncomplicated guide would help.

Wow.... All these comments are so pointless... THERE IS NOTHING TO BE FIXED ONLY IN CASE THAT PORT IS USED AS A BACKDOOR...Otherwise if you have a specific application that uses that port, there is nothing to worry about :/
