- 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.
Port 1293: PKT-KRB-IPSec
Port 1293 is assigned by IANA to pkt-krb-ipsec (PKT-KRB-IPSec).

How pkt-krb-ipsec works
VPN, tunnels & proxiesTraffic is wrapped in a tunnel between the two ends, so the network in between only sees the tunnel.

Is port 1293 dangerous?
We have no specific security note for port 1293. Its risk depends on the program actually listening on it. General advice for vpn, tunnels & proxies services:

Which program uses port 1293, and is it reachable?
Linux
sudo ss -ltnup 'sport = :1293' # process listening on 1293
sudo lsof -nP -i :1293macOS
sudo lsof -nP -i :1293
Windows (PowerShell)
Get-NetTCPConnection -LocalPort 1293 -State Listen | Select LocalAddress, OwningProcess Get-NetUDPEndpoint -LocalPort 1293 netstat -ano | findstr :1293
From another machine
nmap -p 1293 -sV <host> sudo nmap -sU -p 1293 <host> nc -zv <host> 1293
Block it in the firewall
sudo ufw deny 1293/tcp # Linux (ufw) New-NetFirewallRule -DisplayName "Block 1293" -Direction Inbound -LocalPort 1293 -Protocol TCP -Action Block # Windows
What is port 1293 used for?
Port 1293 is assigned by IANA to pkt-krb-ipsec (PKT-KRB-IPSec).
Is port 1293 TCP or UDP?
Port 1293 is registered for TCP and UDP.
Is it safe to open port 1293?
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 1293 is open?
On Linux run "ss -ltnup 'sport = :1293'", on macOS "lsof -nP -i :1293", and on Windows "netstat -ano | findstr :1293" to see the local process. From another machine, "nmap -p 1293 <host>" shows whether it is reachable.
