Is port 1326 dangerous?

We have no specific security note for port 1326. 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 1326, and is it reachable?

Linux

sudo ss -ltnup 'sport = :1326'      # process listening on 1326
sudo lsof -nP -i :1326

macOS

sudo lsof -nP -i :1326

Windows (PowerShell)

Get-NetTCPConnection -LocalPort 1326 -State Listen | Select LocalAddress, OwningProcess
Get-NetUDPEndpoint -LocalPort 1326
netstat -ano | findstr :1326

From another machine

nmap -p 1326 -sV <host>
sudo nmap -sU -p 1326 <host>
nc -zv <host> 1326

Block it in the firewall

sudo ufw deny 1326/tcp                                         # Linux (ufw)
New-NetFirewallRule -DisplayName "Block 1326" -Direction Inbound -LocalPort 1326 -Protocol TCP -Action Block  # Windows
04 FAQ
What is port 1326 used for?

Port 1326 is assigned by IANA to wimsic (WIMSIC).

Is port 1326 TCP or UDP?

Port 1326 is registered for TCP and UDP.

Is it safe to open port 1326?

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 1326 is open?

On Linux run "ss -ltnup 'sport = :1326'", on macOS "lsof -nP -i :1326", and on Windows "netstat -ano | findstr :1326" to see the local process. From another machine, "nmap -p 1326 <host>" shows whether it is reachable.
