- 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.

sudo ss -ltnup 'sport = :5463' # process listening on 5463
sudo lsof -nP -i :5463macOS
sudo lsof -nP -i :5463
Windows (PowerShell)

From another machine
nmap -p 5463 -sV <host> sudo nmap -sU -p 5463 <host> nc -zv <host> 5463
Block it in the firewall

What is port 5463 used for?
Port 5463 is assigned by IANA to ttlpriceproxy (TTL Price Proxy).
Is port 5463 TCP or UDP?
Port 5463 is registered for TCP and UDP.
Is it safe to open port 5463?
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 5463 is open?
On Linux run "ss -ltnup 'sport = :5463'", on macOS "lsof -nP -i :5463", and on Windows "netstat -ano | findstr :5463" to see the local process. From another machine, "nmap -p 5463 <host>" shows whether it is reachable.
