Is port 5072 dangerous?

We have no specific security note for port 5072. Its risk depends on the program actually listening on it. General advice for other services services:

  • Close the port if nothing on the host needs it.
  • Identify the process that listens on it (commands below) before opening it in a firewall.
  • Expose a service only to the networks that use it.

03 Check it

Which program uses port 5072, and is it reachable?

Linux

sudo ss -ltnup 'sport = :5072'      # process listening on 5072
sudo lsof -nP -i :5072

macOS

sudo lsof -nP -i :5072

Windows (PowerShell)

Get-NetTCPConnection -LocalPort 5072 -State Listen | Select LocalAddress, OwningProcess
Get-NetUDPEndpoint -LocalPort 5072
netstat -ano | findstr :5072

From another machine

nmap -p 5072 -sV <host>
sudo nmap -sU -p 5072 <host>
nc -zv <host> 5072

Block it in the firewall

sudo ufw deny 5072/tcp                                         # Linux (ufw)

What is port 5072 used for?

Port 5072 is assigned by IANA to ayiya (Anything In Anything).

Is port 5072 TCP or UDP?

Port 5072 is registered for TCP and UDP.

Is it safe to open port 5072?

It depends on the program that listens on it. Open it only for a service you know and only to the networks that need it. Close the port if nothing on the host needs it.

How do I check if port 5072 is open?

On Linux run "ss -ltnup 'sport = :5072'", on macOS "lsof -nP -i :5072", and on Windows "netstat -ano | findstr :5072" to see the local process. From another machine, "nmap -p 5072 <host>" shows whether it is reachable.
