I have set up a little network at home, for "my own Penetration Testing
Purposes". 2 Windows machines and 2 Linux. I have 1 Windows machine on its
own network running windows XP default install and (Zonealarm, Sygate)
My question:
I want to try to see what approach people take to find Exploits and
Vulnerbilites on a system like this. Soo the first steps i took is:
installed SYGATE with default settings on Windows XP machine, Went over to
Linux and ran a NMAP scan:
nmap -vv -sS -P0 111.111.111.111
all ports are filtered
And SYGATE detected it as only MINOR port scans it didnt even come up with
an ALERT-just logged it!
So then tryed NESSUS against this machine and got back:
results|111.11.111.11|ntp (123/udp)|10884|Security Note|\nIt is possible to
determine a lot of information about the remote host \nby querying th$
results|111.11.111.11|ntp (123/udp)|10647|Security Warning|\nAn NTP server
is running on the remote host. Make sure that\nyou are running the lat$
So i know i would go to sites like Buqtraq,Security Focus and look
for documents on this service and see what i can do with it?
But if it is behind a firewall can it still be exploited???and would disable
the firewall first? or...<-------
Than i installed zonealarm and searched for exploits on it and found this
nmap exploit and ran an NMAP scan like this:
nmap -g67 -P0 -sS 111.11.111.111
And all the ports are filtered :
nmap -vv -sS -P0 -p 1-1064 111.11.111.111 -D www.blah.org
A site I visted from the windows machine earlier for a bounce attack and
still nothing.
My nest option was going to try HPING2 and try to set the Fragment to "0"
and run that against the Firewalled machine too see what happens.
I also remember Windows XP installs MSN Messenger by default. Soo i searched
around more and found this:
http://www.mynetwatchman.com/winpopuptester.asp
And i ran the test with SYGATE firewall enabled, and a POP-WINDOW POPPED UP
Soo that means it can be accesiable right??
"cause the POP-UP came right through"
So that means something is open amd that my SCANS DIDNT PICK UP?? ----> How
come?
Soo can anyone tell me i DONT mean step by step "but(SUGGESTIONS, IDEAS)" on
how do people exploit things or "how they do there own assesments" like
this.(for learning purposes). I have done alittle bit of homeowrk but NOT
ENOUGH.. I want to test HPING against it too but there are just soo many
commands anyone have any good command string they use to test FIREWALLS? How
would some of you approach something like this: im really trying to get into
more secuirty now by reading and playing but am sort of "stumped right now!"
Any ideas (tips) i should try or should do differently that would help me on
my testings.Again this is all against my own machines... and im not asking
steps but maybe a little push..just to learn more about the secuiry issues
with them and learn how hackers would approach ISSUES like this. Ohh ya i
found this code also for bypassing firewalls but dont understand it, i wanna
learn about it beofore i try it and play with it from here:
