Is port 1077 dangerous?

We have no specific security note for port 1077. 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 1077, and is it reachable?

Linux

sudo ss -ltnup 'sport = :1077'      # process listening on 1077
sudo lsof -nP -i :1077

macOS

sudo lsof -nP -i :1077

Windows (PowerShell)

Get-NetTCPConnection -LocalPort 1077 -State Listen | Select LocalAddress, OwningProcess
Get-NetUDPEndpoint -LocalPort 1077
netstat -ano | findstr :1077

From another machine

nmap -p 1077 -sV <host>
sudo nmap -sU -p 1077 <host>
nc -zv <host> 1077
