Kon-Boot is an prototype piece of software which allows to change contents of a Linux kernel (and now Windows kernel also!!!) on the fly (while booting).
In the current compilation state it allows to log into a Linux system as ’root’ user without typing the correct password or to elevate privileges from current user to root. For Windows systems it allows to enter any password protected profile without any knowledge of the password.
It was mainly created for Ubuntu, later the author has made a few add-ons to cover some other Linux distributions.
Entire Kon-Boot was written in pure x86 assembly, using old grandpa-geezer TASM 4.0.
Latest Updates – Kon-Boot for Windows
Kon-Boot was moved to Windows platforms. So now it provides support for Microsoft Windows systems and also the Linux systems listed below. Kon-Boot for Windows enables logging in to any password protected machine profile without without any knowledge of the password. This tool changes the contents of Windows kernel while booting, everything is done virtually – without any interferences with physical system changes. So far following systems were tested to work correctly with Kon-Boot:
  • Windows Server 2008 Standard SP2 (v.275)
  • Windows Vista Business SP0
  • Windows Vista Ultimate SP1
  • Windows Vista Ultimate SP0
  • Windows Server 2003 Enterprise
  • Windows XP
  • Windows XP SP1
  • Windows XP SP2
  • Windows XP SP3
  • Windows 7
No special usage instructions are required for Windows users, just boot from Kon-Boot CD/Floppy, select your profile and put any password you want. You lost your password? Now it doesnt matter at all.
It has been tested with the following Linux distributions:
  • Gentoo 2.6.24-gentoo-r5 GRUB 0.97
  • Ubuntu GRUB 0.97
  • Debian 2.6.18-6-6861 GRUB 0.97
  • Fedora GRUB 0.97
