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 acctually started as silly project of mine, which was born from my never-ending memory problems :)
Secondly it was mainly created for Ubuntu, later i have made few add-ons to cover some other linux distributions.
Finally, please consider this is my first linux project so far :) Entire Kon-Boot was written in pure x86 assembly, using old grandpa-geezer TASM 4.0.
Additional notes:
Typical usage scenario: LIWaP usage scenario: | 1. Boot with Kon-boot CD or Floppy | 2. When Linux is fully booted go to the console mode | 3. Type 'kon-usr' as login, if it works you should be now in the system | 4. !Remember! to restore the system when you are leaving, you can do this by typing 'kon-fix' as login again. | Sample console output: | Ubuntu 8.04 torpeda tty1 torpeda login: kon-usr # id uid=0(root) gid=0(root) # whoami root |
Logging problem? | torpeda login: kon-usr /bin/sh: Can't open kon-usr FIX: type 'kon-fix' as login | |
