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)
Cool. Good for practice ;-)
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:
First: the right order is vulnerabilities, then xploits (if they're available). I think that perhaps you don't have very clear the concept of a xploit. The xploit is the mechanism you use to... well, EXPLOIT a vulnerability you found. It can be a command with certain parameters, a wicked URL, a C program, etc etc etc. If you browse throu differed BIDs in SecurityFocus, you will see that different vulnerabilities have different TYPES of xploits, and some of them didn't have a xploit so far.
installed SYGATE with default settings on Windows XP machine, Went over
to Just a comment. Never used SYGATE myself.
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!
That seems to be good.
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?
USUALLY 123 is NTP (Network Time Protocol), dunno if XP has this open for different purposes (you can never trust Micro$oft ;-)
But if it is behind a firewall can it still be exploited???and would
disable
the firewall first? or...<-------
Let me explain. In the nmap scan above you did a SYN scan, that's TCP. Nessus detected 123/udp open, not TCP. Your firewall seems not to be blocking UDP.
Than i installed zonealarm and searched for exploits on it and found this
nmap exploit and ran an NMAP scan like this:
Sorry, this is not a xploit. This is just a way to use nmap (source port scanning). Has NOTHING to do with a xploit.
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.
No, just try to use nmap's 'UDP scan'.
I also remember Windows XP installs MSN Messenger by default. Soo i
searched Sorry again, this is Windows Messenger, and has nothing to do with MSN Messenger...
around more and found this: http://www.mynetwatchman.com/winpopuptester.asp
Didn't know this link, thanks!
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?
Could be that you'r firewall isn't protecting you in the right way? Or perhaps is "stealthing" your ports, but they still answer a proper request. I've no experience with SYGATE, but I recommend that you read the documentation that come with the product.
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
Get as much information as possible about the target, that include proper port scans, service identification, banner grabbing, etc. Do some search about the services available, to detect those with vulnerabilities (Nesuss can help, but beware of false positives). Check if those with vulnerabilities have xploits available. Got information about the xploits, and the xploits themselves if they're programs. Create a situation similar to your target in your lab. TEST all the xploits and techniques in your lab, until both you're confident, and you what works and what won't work. USE the working xploits on the target.
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 I think that you're trying to get all the information at once, and are getting confused. Go slowly, step by step. I'm here right now, but I started with computerized systems in 1982, and with IT security around 1997. You've to UNDERSTAND how tools like hping2 works, not to use a recipe.
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: http://www.der-keiler.de/Mailing-Lists/securityfocus/bugtraq/2003-02/0268.html
I'll try to visit this link later.
Thanks Mike
I'll suggest that you put your hands on the excellent book "Hacking Exposed, 4th edition".
