- 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 7674, and is it reachable?
Linux
sudo ss -ltnup 'sport = :7674' # process listening on 7674
sudo lsof -nP -i :7674macOS
sudo lsof -nP -i :7674
Windows (PowerShell)
Get-NetTCPConnection -LocalPort 7674 -State Listen | Select LocalAddress, OwningProcess Get-NetUDPEndpoint -LocalPort 7674 netstat -ano | findstr :7674
From another machine
nmap -p 7674 -sV <host> sudo nmap -sU -p 7674 <host> nc -zv <host> 7674
Block it in the firewall

What is port 7674 used for?
Port 7674 is assigned by IANA to imqtunnels (iMQ SSL tunnel).
Is port 7674 TCP or UDP?
Port 7674 is registered for TCP and UDP.
Is it safe to open port 7674?
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 7674 is open?
On Linux run "ss -ltnup 'sport = :7674'", on macOS "lsof -nP -i :7674", and on Windows "netstat -ano | findstr :7674" to see the local process. From another machine, "nmap -p 7674 <host>" shows whether it is reachable.
