SSH


Nmap initially detected a SSH server running on the target port 22 There was nothing to be done as I did not have a valid credential

I have discovered that the web server is running the Pi-Hole web GUI , which is designed to block ads on the network level.

the target system is debian, which is unlikely matching and strange, given the fact that pi-hole is almost always installed on to raspberry pi os.

raspberry pi os also comes with a default credential; pi:raspberry. It did not work on the login page, but I have not tried it on SSH

So I will try that.

Wow. What a surprise.
