Now, I don't encourage hacking anyone’s system so I hope you use this tool for good intentions only! Today I'm talking about Kon Boot v1.1. Simply put, Kon Boot is a boot disc that will allow you to login to any Windows or Linux machine without knowing the password for any password protected account.
The software works by temporarily virtually changing the OS Kernel during boot and "tricking" the system to log in to the account without bothering to verify if the entered password is correct. After rebooting, the changes are reverted and the system goes back to its normal working state.
Kon Boot has been tested on the following platforms:
Windows Server 2008 Standard SP2
Windows Vista Business
Windows Vista Ultimate SP1
Windows Vista Ultimate
Windows Server 2003 Enterprise
Windows XP
Windows XP SP1
Windows XP SP2
Windows XP SP3
Windows 7
As well as
Gentoo 2.6.24-gentoo-r5
GRUB 0.97
Ubuntu 2.6.24.3-debug
GRUB 0.97
Debian 2.6.18-6-6861
GRUB 0.97
Fedora 2.6.25.9-76.fc9.i6862
GRUB 0.97
Again, do not use this to login to systems you are not authorized to use. This tool should only be used as a last resort for individuals such as systems administrators who need access to one of their own machines or in the case you forget your own administrator password and need to reset it.
