Is port 1084 dangerous?

We have no specific security note for port 1084. 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 1084, and is it reachable?

Linux

sudo ss -ltnup 'sport = :1084'      # process listening on 1084
sudo lsof -nP -i :1084

macOS

sudo lsof -nP -i :1084

Windows (PowerShell)

Get-NetTCPConnection -LocalPort 1084 -State Listen | Select LocalAddress, OwningProcess
Get-NetUDPEndpoint -LocalPort 1084
netstat -ano | findstr :1084

From another machine

nmap -p 1084 -sV <host>
sudo nmap -sU -p 1084 <host>
nc -zv <host> 1084

Block it in the firewall

sudo ufw deny 1084/tcp                                         # Linux (ufw)

On Linux run "ss -ltnup 'sport = :1084'", on macOS "lsof -nP -i :1084", and on Windows "netstat -ano | findstr :1084" to see the local process. From another machine, "nmap -p 1084 <host>" shows whether it is reachable.
