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

Sinatra default server port in development mode (HTTP)

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

Backdoor.Win32.Visiotrol.10 / Insecure Password Storage - the malware listens by default on TCP port 4567. The default password "vc" is very weak and stored in a plaintext file named "config.vcs" on disk.

A vulnerability was found in MariaDB. An OpenVAS port scan on ports 3306 and 4567 allows a malicious remote client to cause a denial of service.

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.

SANS ISC: port 4567

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.

Sinatra.rb applications use port 4567 by default.

I wish I could understand what this all means, pensiioners (not all) have only a vague idea how things work - so I can't tell how well you have done because I can't understand a word!! Sorry.

I can't understand any of this, I also am a pensioner and have no idea of what to do about this. I just use my computer normally but this is frightening me
by anonymous - 2016-07-29 08:06
This is typical and too complicated to understand. just do it if it is my interest
Username? password? dont @bother me cagain.

I do not understand any of this and as I use bullgaurd I thought I was cleared / covered from any Hackers

I have no idea how to fix this, a uncomplicated guide would help.
by anonymous - 2016-10-22 09:14
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 :/

Nothing to fix? Maybe not if you know what the hell it's all talking about. Reference to this has come up in Computeractive, so I looked at this site and don't understand any of it - don't even understand about the 'port'. It's like so many information sites - fine if you're a techie anyway. Come down to earth you boffins.

Ray, it is sometimes hard to address all audiences, that is why we have forums, you can ask questions and get more personal assistance.

Ports are communication channels, i.e. when two computers communicate on the internet, they send and receive information through "ports". Different programs/games/viruses are known to use different such "ports", and we have an extensive database that lists them all.

Generally, if you don't know what's using a "port", you should try to find out, run anti-malware programs, etc. You are always welcome to sign up for our forums and ask if you need assistance.

I found traffic blocks on this port originating from Iran at IP: 2.186.116.38. Interesting that this port has significantly increased usage since 1 Jan 2020. I don't have enough storage to go back that far to look, but I suspect that this traffic is related to Iran's pending cyber attack. I believe this will end up being Iran's tactic for retaliation from the death of General Soleimani.
