Is port 1072 dangerous?

We have no specific security note for port 1072. 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 1072, and is it reachable?

Linux

sudo ss -ltnup 'sport = :1072'      # process listening on 1072
sudo lsof -nP -i :1072

macOS

sudo lsof -nP -i :1072

Windows (PowerShell)

Get-NetTCPConnection -LocalPort 1072 -State Listen | Select LocalAddress, OwningProcess
Get-NetUDPEndpoint -LocalPort 1072
netstat -ano | findstr :1072

From another machine

nmap -p 1072 -sV <host>
sudo nmap -sU -p 1072 <host>
nc -zv <host> 1072

Block it in the firewall

sudo ufw deny 1072/tcp                                         # Linux (ufw)
New-NetFirewallRule -DisplayName "Block 1072" -Direction Inbound -LocalPort 1072 -Protocol TCP -Action Block  # Windows

What is port 1072 used for?

Port 1072 is assigned by IANA to cardax (CARDAX).

Is port 1072 TCP or UDP?

Port 1072 is registered for TCP and UDP.

Is it safe to open port 1072?

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 1072 is open?

On Linux run "ss -ltnup 'sport = :1072'", on macOS "lsof -nP -i :1072", and on Windows "netstat -ano | findstr :1072" to see the local process. From another machine, "nmap -p 1072 <host>" shows whether it is reachable.
