Still Chntpw and OPHcrack work with Windows 11?

Previously, we tested to check, if we could bypass Windows 10 login screen using Chntpw and OPHcrack, and we succeeded. In this video, we will be going to take a look at, if we could bypass Windows 11 logon screen using chntpw and OPHcrack.

Before that, we will have to Boot the computer using Kali Live bootable CD or USB drive that contains chntpw and OPHcrack.

Steps to create a Bootable Kali Live USB Persistence

Kali Linux is a distribution of Linux that is specifically designed for penetration testing, digital forensics, and other security-related tasks. A "Live " version of Kali allows the user to boot the operating system from a USB drive , rather than installing it on a computer's hard drive.

Firstly, let’s take a look if we could crack the Windows 11 login passwords using OPHcrack. 

Using OPHCrack

To learn more about OPHcrack click the below link:

Ophcrack is a free and open-source program that lets you bypass Windows log-in passwords by using 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. Kali Live USB persistence 1.

Shut down your Windows 11 PC and then Boot Kali Linux with the help of Live USB Persistence.

Now, we have to copy SAM and SYSTEM files from the Windows Hard Disk Partition. So, Click on the Windows system partition on the desktop screen and Open the terminal from Here.

Change the directory to the Windows system configuration file where the SYSTEM and SAM files are stored.

┌──(kali㉿kali)-[/media/kali/8c76EFA67EF8F70]

└─$ cd Windows/System32/config

┌──(kali㉿kali)-[/media/.../8c76EFA67EF8F70/Windows/System32/config]

└─$ 

Now copy these two files to the Desktop.

┌──(kali㉿kali)-[/media/.../8c76EFA67EF8F70/Windows/System32/config]

└─$ cp SAM SYSTEM /home/kali/Desktop

Now we have to convert SAM and SYSTEM files to Windows password hashes using the SAMdump2 command line utility.

┌──(kali㉿kali)-[~/Desktop]

└─$ samdump2 SYSTEM SAM -o windowskey.txt

Once the Dump file is created, launch OPHCrack.

Click on load, and Load the Password Dump file from the Desktop.

Since the NT password section is showing empty, which means it is not possible to crack passwords using OPHCrack.

Next, we will try to take a look, if we could reset Windows 11 password using chntpw.

Similar to the previous, type 1, to edit user data and password. 

Next, enter the user number, which we want to remove. 

Type 1, to clear or Blank the user password.

Type 2, to unlock and enable the user account. 

Type q to back to user select. 

 Type q to close the session and also save the file. 

Once done, Remove the USB drive and reboot the computer.
