Change your password with sticky keys

August 18th, 2010 by admin in Privilege Escalation, windows

Forgot the administrator password? There are many ways to access a Windows installation if you forgot the administrator password. Today I’ll show you another procedure to reset the Windows password by replacing the Sticky Keys application. This program allows you to use the function keys SHIFT, CTRL, ALT, or the Windows key by typing one key after the other instead of pressing them simultaneously with the second key. The main advantage of this password reset method is that you don’t need third-party software; another plus is that it is easy to carry out because no Registry hack is required, as when you offline enable the built-in administrator.

Please note that resetting the password from an account other than the corresponding user account always means that the user loses the credentials stored in the Windows Vault, stored Internet Explorer passwords, and files that you encrypted with the Encrypting File System (EFS). Of course, if you have a backup of these credentials, you can restore them; likewise, if you have exported the private EFS key, you can import it again after you have reset the password.

Like with all other solutions that allow you to reset the Windows password without having an account on the corresponding computer, you have to boot from a second operating system and access the Windows installation while it is offline.

You can do this with a bootable Windows PE USB stick or by using Windows RE. You can start Windows RE by booting the Windows Vista or Windows 7 setup DVD and then selecting “Repair” instead of “Install Windows.”

By the way, you can’t use the Windows XP boot CD for this purpose because its Recovery Console will ask for a password for the offline installation. However, you can use a Vista or Windows 7 DVD to reset a forgotten Windows administrator password on Windows XP.

This works because Windows RE, which is based on Vista or Windows 7, will let you launch a command prompt with access to an offline installation without requiring a password.

Kon Boot 1.1

May 10th, 2010 by Dev Team in cracking, Privilege Escalation, windows

Kon Boot 1.1
We reviewed Kon Boot 1.0 last year HERE which was a great breakthrough program that allowed you to boot into a Windows machine and bypass the logon screen without entering a password. To accomplish this, Kon Boot hooks the bios on the fly subverting the Windows kernel authentication temporarily and allowing you access. Since this is a temporary process the computer is back to normal when you reboot. This allowed you to access the computer without having to take the time to reset the password or crack it, and it left the computer untouched. Now, a year later, Kon Boot v1.1 has been released with new features, such as booting from floppy,CD, or usb, privilege escalation support which allows you to gain SYSTEM privileges from ANY account on the system. For example, you can boot from Kon Boot and log in as Guest and run ‘Net User’ command to add a new user,reset admin passwords etc as SYSTEM

It also has a bunch of new bug fixes/updates.

  1. – Added 64-bit environment support
  2. – Added USB support tools (grldr, klmemusb)
  3. – Added debugging code to make it easier to track down various compatibility problems
  4. – Fixed bug in Windows 7 support failures
  5. – Removed Linux support
  6. – Many performance improvements to source code
  7. – Improved BIOS support by reducing code size significantly

Unfortunately it is no longer free. But for a meager price of $15.99 for a personal license, it gives you free updates and support for a period of 6 months. You can still use it without restrictions after that period.
They also offer a commercial license, for $75.99 with 1 year of support and updates, allowing you to use on business environment.
To purchase Kon Boot v1. 1,visit their website http://www.kryptoslogic.com

We are also giving away 10 personal licenses this week to some lucky readers!!! More details to come!!!

DPAPIck – Recover offline passwords

April 6th, 2010 by Dev Team in Password Info, windows

This is a forensic tool to deal, in an offline way, with Microsoft Windows® protected data, using the DPAPI (Data Protection API).
A non-exhaustive list of those recoverable secrets are :

* EFS certificates
* MSN Messenger credentials
* Internet Explorer form passwords
* Outlook passwords
* Google Talk credentials
* Google Chrome form passwords
* Wireless network keys (WEP key and WPA-PMK)
* Skype credentials

Of course you need to know the user’s current password, you can recover it from the SAM.

You can also read an excellent article on the undocumented process of recovering DPAPI passwords here

Hive Restore XP

February 28th, 2010 by Dev Team in Our Tools

When you try to start or restart your Windows XP-based computer,
you may receive one of the following error messages:

Windows XP could not start because the following file is
missing or corrupt: \WINDOWS\SYSTEM32\CONFIG\SYSTEM

Windows XP could not start because the following file is
missing or corrupt: \WINDOWS\SYSTEM32\CONFIG\SOFTWARE

Stop: c0000218 {Registry File Failure} The registry cannot load the hive (file): \SystemRoot\System32\Config\SOFTWARE or its log or alternate

System error: Lsass.exe
When trying to update a password the return status indicates that the value provided as the current password is not correct.

Sometimes this can be corrected using chkdsk /r /f from recovery console

other times you need to boot into the recovery console using the XP install CD
and use the directions here http://support.microsoft.com/kb/307545 which involves typing a
whole bunch of commands into the console and hope that you dont make any mistakes typing.
Alot of people either lost or don’t have the XP install CD and if you do it’s a pain in
the ass to type all of that.

So the alternative would be to either:
1. boot from WindowsPE type disk and backup/copy the registry hive files to the folders
or
2. slave the drive to another computer and backup/copy the registry hive files to the folders

which is also tedious because you have to copy hive files over,back up old hives, and rename the new hives
This is where HiverestoreXP comes in handy because it automates the process for you.
It’s dead simple to use.



Download HiveRestoreXP

[downloadcounter(HiveRestoreXP)] downloads

If you are trying to use this on a slaved drive you may not have proper permissions to open the “System Volume Information” folder and the program wont show any restore points, use the instructions here to take gain access before running the program http://support.microsoft.com/kb/309531

most of the time you can run this command:
cacls "driveletter:\System Volume Information" /E /G username:F
then remove the permissions using this:
cacls "driveletter:\System Volume Information" /E /R username

How to View Your Windows 7 Homegroup Password

December 3rd, 2009 by admin in Password Info, windows

If you have forgot your Windows 7 homegroup password, then this will show you how to view or print it to see what it is again. You must have this password to be able to join a computer to your homegroup.

HomeGroup makes it easy to share pictures, music, documents, videos, and printers with other people on your home network. You would have had to created a homegroup first before you will have a password to use to join other computer to your homegroup.

1. Open the Control Panel (all items view), and click on the Network and Sharing Center icon.
2. Click on the Choose homegroup and sharing options link.
3. Click on the View or print homegroup password link.
4. Write down this password down, or click on Print this page to print the passoword. When done, close this window.

NOTE: The password is case sensitive, so it will need to be typed exactly as it appears here when used to join a computer to the homegroup.
