- Patch VPN gateways quickly: they are a top initial access target.
- Use certificates or MFA rather than shared secrets.
- Investigate unexpected tunnels and proxies: they are also attacker tools.

Which program uses port 7675, and is it reachable?
Linux
sudo ss -ltnup 'sport = :7675' # process listening on 7675
sudo lsof -nP -i :7675macOS
sudo lsof -nP -i :7675
Windows (PowerShell)

From another machine
nmap -p 7675 -sV <host> sudo nmap -sU -p 7675 <host> nc -zv <host> 7675
Block it in the firewall

What is port 7675 used for?
Port 7675 is assigned by IANA to imqtunnel (iMQ Tunnel).
Is port 7675 TCP or UDP?
Port 7675 is registered for TCP and UDP.
Is it safe to open port 7675?
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. Patch VPN gateways quickly: they are a top initial access target.
How do I check if port 7675 is open?
On Linux run "ss -ltnup 'sport = :7675'", on macOS "lsof -nP -i :7675", and on Windows "netstat -ano | findstr :7675" to see the local process. From another machine, "nmap -p 7675 <host>" shows whether it is reachable.
