Cracking/Hacking Windows Passwords (UPDATED: VISTA too!!)

Picture of Cracking/Hacking Windows Passwords (UPDATED: VISTA too!!)
xpboot.gif
Instructional/Educational Purposes only.
Be nice kids.

First of all, and I have to say this because of some recent comments, this is not a virus, and will not delete any files from your computer. In fact, ophCrack, the software we're gonna use is a very popular password cracker. Google it or Wikipedia it if you don't believe me.

This works for WINDOWS ONLY
UPDATE: WORKS FOR XP AND VISTA

This will crack all windows passwords up to 14 digits on a computer.
You need physical access to the computer.
You don't need to be logged in (that's what this is for).
It will tell you all user names and passwords on the computer.

 

Step 1: Get the resource

1. Go here:
http://ophcrack.sourceforge.net/download.phphttp://ophcrack.sourceforge.net/download.php

2. Download the latest version of ophcrack live cd. To crack passwords on an XP computer select 'ophcrack XP LiveCD'. To crack passwords on a VISTA computer select 'ophcrack VISTA LiveCD'.

3.The software you download will be a CD image (.iso format). If you try opening this on a computer with a CD-Writer and CD-Writing Software (eg. Nero, Roxio, Record Now, or whatever you have) it will write that file to a CD.
So, make the CD

Step 2: Crack

1. Make sure the computer you intend to crack is off.

2. Turn on, and instantly pop in the CD you just created.

3. By this time, windows might have started loading. So, turn off computer by holding down power button and then turn on again. What you want to do is boot from the CD. This can be done in two ways:
a. Often pressing one of the function keys (depending on manufacturer) takes you into the BIOS setup (the first splash screen that pops up when you turn on your computer should tell you which one: often F2, F11 or F12.) There, you should look around until you find where you can change the boot order (this differs from company to company depending on your computer brand). Change the boot order, so the computer first boots from CD then from Hard Disk.
b. There is often another function key (again depending on manufacturer) which enters you into the boot selection menu where you can select where to boot from. Hit boot from CD.

4. Watch as the CD loads. It will load a temporary version of linux on to the ram, dump all user names in a box and start processing. This software can only crack passwords up to 14 digits. As it deciphers the passwords, it will decipher each password in two blocks of 7 characters each, and then show you the whole password as a combination of those two under the column labeled 'net password'.

5. Vola! In about 5-10 minutes you have all the user names and passwords on that computer.

How do I get out of Safe Mode?

From Windows Safe Mode, click Start, Shutdown, and restart the computer. This will start the computer automatically back into Normal Mode.
Note: Many users believe that they are still in Safe Mode because the colors or video may not look correct. Unless in the corners of the screen it says "Safe Mode", you are not in Safe Mode. For information on how to setup your video card resolution, see document CH000190.
If you are rebooting the computer and it is rebooting back into Safe Mode (it does say "Safe Mode" in each of the corners), it is likely another problem exists with Windows preventing it from loading into Normal Windows. We recommend you see the basic troubleshooting section for additional ideas that may help to resolve your issue.

Which Safe Mode option should I choose?

Users who are running later versions of Windows will get different options for different versions of Safe Mode. For example, you may have options for "Safe Mode", "Safe Mode with Networking", and "Safe Mode with Command Prompt." Below is a brief description of each of these different modes.
Safe Mode
The basic Safe Mode option is usually what most users will want to choose when troubleshooting their computer. This is the most basic Safe Mode option and has no additional support.
Safe Mode with Networking
For users needing access to the Internet or the network they're connected to while in Safe Mode, users may want to choose this option. This mode is helpful for when you need to be in Safe Mode to troubleshoot, but also need access to the Internet so you can get updates, drivers, or other files to help troubleshoot your issue.
Safe Mode with Command Prompt
This Safe Mode allows you to have access to the command line (MS-DOS prompt).

How to Get a Computer Out of Safe Mode


Microsoft introduced the Safe Mode as a troubleshooting solution for potential problems encountered by the computer system via loading only the bare essentials like the keyboard, mouse, and video processes needed to boot the machine. Some of the reasons a computer boots into Safe Mode is a corrupted device driver, missing or damaged system file (Dynamic Link Library), or if it is explicitly chosen by the computer user for fixing computer problems. During the booting up process into Safe Mode, indications of what is causing the problem are usually shown via the display of system generated messages. These include “Windows failed to load completely” or “Windows was not properly shut down”, and others. With the introduction of the Microsoft Windows XP Operating System platform, the Safe Mode status was extended with the “Safe Mode with Command Prompt” and “Safe Mode with Networking” options to allow for more support for the troubleshooting process.


Materials Needed:- Computer
- Microsoft Windows Operating System

Step 1

Getting out of Safe Mode may be both easy and complicated at the same time. The primary consideration is the reason why the machine is booting into this status. If it was user initiated, the easiest way is to click on the 'Start' button and select the 'Turn Off Computer' option.

Step 2

This will bring up the window with the 'Standby', 'Turn Off', and 'Restart' options. Choose either 'Restart' or 'Turn Off'. Upon rebooting or powering up of the machine, the Operating System should automatically load into Normal Mode. Take note that some users are misled into believing that the system is in Safe Mode primarily due to the incorrect setting of the video. If the system is in Safe Mode, it should be stated at the corners of the screen.

Step 3

If the system keeps on rebooting on Safe Mode, this is a possible indication of a problem in loading startup components. Reboot the machine.

Step 4

During the reboot process, press the 'F8' key to display the boot-up options. In this window, select the 'Last Known Good Configuration' option. The Operating System will attempt to locate the last settings that successfully loaded the Operating System. This feature was introduced under the Microsoft Windows 2000 Operating System platform and retained in newer Microsoft environments.

Step 5

If still unsuccessful, allow the machine to boot into Safe Mode. Click on the 'Start' button and choose the 'Control Panel' option.

Step 6

Click on the 'Performance and Maintenance' category and click on the 'System' icon. This should open the System Properties window.

Step 7

Click on the 'Hardware' tab and click on the 'Device Manager' button. Check for any exclamation or question mark beside any entry. Reload the corresponding device driver for the erroneous component. Repeat Step 2; this should boot the system in Normal Mode.

Step 8

If the computer system entered Safe Mode via the System Configuration utility, then it can only boot in Normal Mode using the same tool. Click on the 'Start' button and choose 'All Programs'. Click on the 'System Tools' category and select the 'System Information' option.

Step 9

From the new window, click on the 'Tools' Menu and select 'System Configuration Utility'. Under the 'General' tab, select the 'Normal Startup' option.

Step 10

Click on the 'OK' button and restart the machine as described in Step 2. This will load the system in Normal Mode.

In the system tray (usually in the bottom right corner of your computer screen), click (or double-click) the icon for your wireless connection software (see examples above). It should list your SSID (wireless network) from the previous step. Select your SSID (wireless network).

Here are the instructions for connecting to a wireless network:

Sometimes the wireless on your laptop accidently gets turned off by bumping a button, switch or hitting a key combination. This makes it so that your laptop can no longer connect to wireless networks.

Step 5: Find the Key



Your operating system will ask you to enter a key/passphrase or WPS PIN. Locate the requested information from the bottom of the modem.

Step 6: Verify Modem Settings
