||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
Sinatra default server port in development mode (HTTP)

IANA registered for: TRAM
||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.

SANS Internet Storm Center: port 4567
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.
