Is port 4484 dangerous?

We have no specific security note for port 4484. 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 4484, and is it reachable?

Linux

sudo ss -ltnup 'sport = :4484'      # process listening on 4484
sudo lsof -nP -i :4484

macOS

sudo lsof -nP -i :4484

Windows (PowerShell)

Get-NetTCPConnection -LocalPort 4484 -State Listen | Select LocalAddress, OwningProcess
Get-NetUDPEndpoint -LocalPort 4484
netstat -ano | findstr :4484

From another machine

nmap -p 4484 -sV <host>
sudo nmap -sU -p 4484 <host>
nc -zv <host> 4484

Block it in the firewall

sudo ufw deny 4484/tcp                                         # Linux (ufw)
