Based on my research it is a port used by malware and/or spyware; not a legitimate service, unless you have configured it as such.

I would try and run a malware scan using one of the following tools, if you're worried:

1) http://www.malwarebytes.org/
2) http://www.safer-networking.org/
3) http://www.bleepingcomputer.com/download/combofix/

Apparently it is used by Verizon at least to send updates to some devices.  http://www.dslreports.com/forum/r20511704-Westell-6100-F90-port-4567

The 'official' list of assigned ports is here http://www.iana.org/assignments/service-names-port-numbers/service-names-port-numbers.xml but it takes forever to load.

Hm, interesting. The only way that would show up on a server/computer then is a Verizon dongle was used (maybe as internet failover)?

One article said that it showed up in an 'online' security scan which actually checks the modem and not necessarily the computer connected to it.

Interesting, well, it seems a Verizon device is definitely used though; that would explain it. I have so far not used a Verizon device (other than a smartphone) in conjunction with a computer. Good to know though.

How are you seeing that port in use?


It is a high port (> 1023), which means if an application requests a non-specific port it could  be randomly chosen.
