Make your first Virus!!!!!!! ------ named "SHUTDOWN"

Hey guys,  here is a small batch programming which is able to shutdown a computer.!!!!!!!!
 Just open a new text document and type:

@echo off
shutdown -s -t 10 -c "WARNING= you are going to shutdown "


and "save as" the file in .bat format.
A executable .bat file will be created and execute that.
your system will shutdown.



And To prevent from the shutdown
Press "start+r" and type:
 shutdown -a
Shutdown will be aborted.


Here, the commands
s= shutdown
t= time
c= characters

or,
To perform restart replace "s" with "r"  and its done!!!!!!!!!

Note:
For further information about Batch programming read another article aboutBatch programming basics.

Learn to make Batch Files!!!!!!!

Making Batch Files


A batch file is a normal text file, no programming involved. You type DOS commands into a text file, each one on a separate line. Then, you give the text file a .bat extension instead of a .txt extension. Now, when you double click the batch file(In Windows Explorer) or type its name at the DOS prompt, it will execute the commands.

First, we need to know some DOS commands. The main DOS commands we will use are copy, move, del, cls, and echo. 
The COPY command has this syntax:
          
copy [source] [destination]

In DOS help, the syntax is more complicated, but we don't need the advanced features for our batch files. 

The COPY command, obviously copies a file. For example, say I wanted to copy a:\readme.txt to a:\windows\help.txt. (By the way, this will also rename the file.) I would type this:

copy a:\readme.txt a:\windows\help.txt

The MOVE command is exactly the same, except it MOVEs the file, and COPY copies the file.

The del command is very simple. It erases a file. It follows this syntax:

del [filename]
 For example, if you wanted to delete a file called a:\happy.txt you would type this:

del a:\happy.txt

The CLS command clears the screen. This is the syntax:
cls
PAUSE is a command that stops the program and prompts you to "Press any key to continue." The syntax is:
pause

ECHO is a DOS command that shows the stuff you type. In a batch program, the @ symbol means not to echo a line. So, typing ECHO OFF prevents the user from watching the batch program execute. And, to keep from echoing the ECHO OFF command, type the @ symbol in front of it. Put it together and you get:

@echo off

All good batch programs start with the @ECHO OFF command followed by CLS. Important!: If you use the @ECHO OFF command in your batch program, be sure to put ECHO ON at the end of the batch program or the user will think their computer is messed up. The ECHO ON command is like this:
echo on


Now for the batch file! First, if you're using Windows, open a DOS prompt. To make a batch program to load a program called myname.bat, type this:

edit myname.bat

Then type:
@echo off
cls
echo Hi, my name is %1
pause

echo This is the contents of this batch file:

pause

type myname.bat

Then save it in a file called myname.bat. The "%1" allows you to add data to your batch file from the command line. Whatever you type after the batch filename at the dos prompt will replace the %1.

At DOS prompt, type
myname Arien
( you can use your name here) and your program will start!



ENJOY!!!!!!!!!

Recover/Crack your windows Xp, Vista and 7 passwords using OPHCRACK




Windows password lost what to do??????
It may be the questions when you lost one. Today I am going to talk about cracking or recovering the windows password using OPHCRACK.
According to windows, there are no way of recovering a password and you must format your system.
But you can try by booting your system  in safe mode. If there's a administrator password set then this cant be a option. So let's try Ophcrack .

Ophcrack is a Rainbow Table based freeware which uses LM hases invented to crack passwords.
But if you are willing to reset your password rather than recovering than you can go through
Reset password of windows xp/ vista/ 7

Thus to use the Ophcrack just follow the following steps:
Step 1:
Download Ophcrack from the following links below:
For Xp (415.65 MB):  http://space.dl.sourceforge.net/project/ophcrack/ophcrack-livecd/2.3.1/ophcrack-xp-livecd-2.3.1.iso
For Vista (496.24 MB):  http://space.dl.sourceforge.net/project/ophcrack/ophcrack-livecd/2.3.1/ophcrack-vista-livecd-2.3.1.iso

Then just burn the iso file into CD by any iso burner. But make it bootable.
In  case of USB installation just refer to my article on Making a USB drive bootable.

Step 2.
 Now just insert the CD or USB in your computer. Then you must put the boot priority of CD to 1st if you are booting from CD and if you are booting from USB then you must put the boot priority of USB to 1st.
To do this you need to go to bios setup and change the order. For most of the systems the keys like DELETE, F10, F2, F12 etc are used for going to the Bios setup.

Step 3.

After booting from the Live CD, wait for it to load and select Ophcrack VESA mode(Recommended). If you have a graphics card you can try Graphics Mode.

Step 4.
If you have more than one partition containing the password hashes in-case if you have more than one OS installed  it will ask you to select one. But most of the computers will have only one hash partition, so you may not see this step. Select any partition if it gives a multiple options and press enter.

Step 5.
Wait for Ophcrack to run find your password. After getting the password you need,you can simply click exit even if the progress is not 100%. No need to wait till end.

 Step 6.
After the process it will ask you to press any key to exit Ophcrack. Then Type ‘y’ to shutdown the System.

Thus it is a simple tool and easy to use. It can recover upto 14 alphanumeric passwords.
To crack a strong password the vista and xp special tables can also be found.

Enjoy!!!!!!!!!!!!!



Making a USB drive bootable.



There are many ways to make your USB Bootable & I have presented some of them to you,

Method 1 : From use of softwares like 
 Boot-USB-Stick 
 UNetbootin 
 WinToFlash
 WiNToBootic
 
Method 2: Or you can manually make your USB disk bootable by:
( This method is especially used for Windows 7 only)


1. Insert your USB (4GB+ preferable) stick to the system and backup all the data from the USB as we are going to format the USB to make it as bootable.



2. Open Command Prompt. To do this Press Start +R, Type cmd and enter then the CMD window pops out.



3. When the Command Prompt opens, enter the following command:
DISKPART and hit enter.
LIST DISK and hit enter.
Once you enter the LIST DISK command, it will show the disk number of your USB drive. let us assume my removable disk is 
Disk 1. 


4. In this step you need to enter all the below commands one by one and hit enter. As these commands are self explanatory, you can easily guess what these commands do.
SELECT DISK 1 (Replace DISK 1 with your disk number)
CLEAN
CREATE PARTITION PRIMARY
SELECT PARTITION 1
ACTIVE
FORMAT FS=NTFS
(Format process may take few seconds)
ASSIGN
EXIT
Don’t close the command prompt as we need to execute one more command at the next step. Just minimize it. 


5. Insert your Windows DVD in the optical drive and note down the drive letter of the optical drive and USB media. Here I use “G” as my optical (DVD) drive letter and “H” as my USB drive letter. 


6. Go back to command prompt and execute the following commands:



6.1. Change directory to the DVD’s boot directory where bootsect lives:
         d:
         cd d:\boot



6.2. Use bootsect to set the USB as a bootable NTFS drive prepared for a Vista/7 image. I’m assuming that your USB flash drive has been labeled disk H:\ by the computer:
         bootsect /nt60 h:

(Where “H” is your USB drive letter)



7. Copy Windows DVD contents to USB.
You are done with your bootable USB. You can now use this bootable USB as bootable DVD on any computer that comes with USB boot feature (most of the current motherboards support this feature).
