This is our third and final challenge in this section.
I'm Josh Mason, and I'll be walking you
through this challenge.
Will grab our IP address.
You gave us the one 192.57.232 and it'll
be dot-3 for all of our work.
So just ping it real fast.
And It is there.
Let's run that.
I'm going to put in a T4 for speed
and see if we get anything.
And it's scanned.
Top out.
That was really fast and found nothing.
We'll run it with -p- to run all the TSP ports.
And that came back really fast with nothing.
So then we go with the less fun.
-su.
And this might take a while.
That took a while.
It says it scanned for 1,032 seconds.
So it's close to--
it was a while.
Anyways, we see that we have port 161 open with SNMP.
Now, I don't know much about that SNMP.
It is just a best guess based on that port.
So let's scan 161 and do an aggressive scan, just
on that single port.
This should go a lot quicker.
And it did.
It came back with some useful stuff.
All right.
So it's running SNMP Version 1 Server and that SNMP.
Good to know.
There's some things that it is asking.
What interface do we have that is publicly facing?
The only two interfaces are this loopback, LO, and eth0.
So eth0 with the 192, it's going to be
the public-facing interface.
So eth0.
Then, we're looking for some SSH keys for David.
And this ran some scripts.
It did some enumeration for us.
That aggressive scan with the -sc and -sv included
gets you a lot of good information.
So we see SSH utilizes tack-i, which will take a key.
So the key is held at opt/david_key.
It's good to know.
And then, there is a loopback report that we're listening on.
And you can see we're listening on port 22 for TCP.
And then also listening on this 1313.
This is really helpful.
And we could try to connect, if we own this machine, to figure
out what we were running there.
But it's only on loopback.
So we're not going to see it, I don't think.
But that was the challenge.
It was really to have you run a UDP scan.
And we found what we were looking for.
