KON-BOOT is a project started by a user who obviously have an infatuation for a character on the Bleach anime. Despite the silly sounding name, this bootable CD ISO/Floppy allows you to hack the kernel of Windows and Linux operating systems on-the-fly. The result? Complete takeover of any machine just by being able to have physical access to it.
We often see in movies scenes, illogical sometimes, involving a person facing a problem of having to guess the password to the villian’s computer. Usually there are some creative ways employed that gives the hero inspiration for guessing the correct password, such as glimpses into the villian’s mind, piecing together clues and other literary licenses. However, in real life it’s not always the case.

Enter KON-BOOT.
For the first time, reality is better than fiction. By inserting this CD and booting the computer from it, the software dynamically patches the kernel of most major Windows and Linux operating systems allowing you to login as the administrator effortlessly. Once you are done, simply execute a command and KON-BOOT will wipe all traces of itself and your victim is none the wiser.
Head on over to the author’s website and snag a copy. It works for all versions of Windows up to 7. The author did not disclose much technical information on how KON-BOOT works, or whether it can be countered via a security fix by Microsoft. Whatever the case, feel proud knowing that you can PWN any password-ed computers you come across now.

Wow! Amazing tool. So, if we set the administrator’s password on Windows OS, other people still able to access our login. Isn’t it dangerous?

That means we need to also set the password inside the bios, weld up our casing, attach a 3-ton lock to the casing just in case anybody wants to break open the casing…

I can understand windows but linux? I thought it was almost impossible to break linux’ passwords. Guess I was wrong.

Yeah this software is a little scary. In the wrong hands, this software could really damage a computer. On the other hand, it sure would be fun to have control over someone else’s computer.

If you lost windows password. I think the best solution is making a windows password recovery disk with the third part utility. The disk works perfectly to recover windows password to “Blank”. It is also useful for administrator password recovery, you can wrote it to an blank CD or USB flash drive to recover administrator password. Booting up and clearing a password takes a minute or two works like a charm.

Hi,
have anybody tried konboot 1.1 on Windows 7 64bit with more then one user? I have win 7 64 bit with two administrators accounts. I password protected both of them just to try this software. it boots normally, I can see the kon-boot screen, press enter, checks the bios or whatsoever and then it let me go alltheway onto logon screen but when I picked up on fo the user’s account and try to hit the enter without typing anything, it told me user name or passowrd is incorrect. When I type the password it let me go normally through … Anyone have some experiences with this?? Thanks

I think the best method to recover windows password is using windows password recovery software. Burn the .iso file to a blank CD or DVD, insert the CD into the problem computer and your password will be reset to “Blank” without losing any data and you needn’t reinstall windows OS.

It doesn’t *break* the passwords. It modifies the kernal to ignore whether the password you input is correct or not. And the Linux kernal is Open Source
To the people wondering why it didn’t work on their 64 bit systems? The older version of Konboot was 32-bit only.
Yes, i realize how old this page is, but I thought I’d put the comment up anyways.

i can tell you this much, laptops nd computers can now be stolen and hacked by just about anyone, so people will not nhesistate to steal them knowing they wont be able to access it.
im going o try kin-boot at school and access lan schools, a program which can broadcast a message over all computers in the school, or show an image , which cannot be minimized without disconnecting the ethernet cables.
this is bad, really bad, hopefully there are things that can be done to computers to disallow kin-boot, so it can only be used on computrs that people own themselves if they forget their password

There are plenty of ways to get past the bios. People not knowing is a good thing. But for those of us, AKA me, who do know, konboot is just an extension to what unrestricted access is all about. Getting past the bios is easy, and after that, thanks to konboot getting into the harddrive is just as easy. But The only protection that is remotly helpful would be to encrypt your drives, because hackers or crackers, will get the first step and the last right. But Not everyone encrypts Entire harddrives so, your more protected doing all three…. and also enable boot logging in your bios. And always have a hidden encryption.
im protected, what about you? and email me at Nick.Frillman@hotmail.com if you want to know how to protect yourself, for free. Im an IT tech.

If you lost your windows log on password, you can try these methods:
Method 1: Log on as admin to reset the password. When installing Windows, it automatically creates an account “Administrator” and the default password is blank. If you have previously created a password reset disk, you can use it to reset the password also.
http://support.microsoft.com/kb/321305 for more info.
Method 2: You can try free software such as Ophcrack,Offline NT Password & Registry Editor,PC Login Now and Kon-Boot. More details here: http://pcsupport.about.com/od/toolsofthetrade/tp/passrecovery.htm
Method 3: Use 3rd party password recovery tool (eg. Windows Password Rescuer and Windows password tools) to reset your windows password. See help page at http://www.daossoft.com/documents/how-to-reset-window-2000–xp-vista-win7-password.html

if your looking to defend yourself from this awesome piece of software. The only way is to encrypt your entire harddrive. A good piece of software to encrypt with is Truecrypt
http://www.truecrypt.org/
as to getting the software itself, you can get it here
http://www.piotrbania.com/all/kon-boot/
pick any of the downloads that say “CD-Iso”
when you unzip the file the password is “kon-boot” minus the quotations.
On a windows:
insert a blank CD (doesnt have to be very big, i used a 700mb)
clicking on the Iso should open the option to burn to a CD
mac:
open disk utility
go to “file”
click “open disk image”
then navigate to the Iso and select it.
it should mount itself
click on the new mounted file and click the “burn” button
looks like a circular hazardishy sign thingy
Using kan-boot:
insert your new CD into the drive of your target computer
reboot
press f12 while rebooting
select the CD drive
enjoy

Wow, I’ve never seen so many people lose their heads over such a simple piece of software. To all who have lost themselves to paranoia, this software doesn’t do anything that couldn’t already be done. All things considered, the act of password protecting a profile only keeps the honest people honest. Anyone who knows enough to about computers to do any real damage does not need this tool to do so. If you are worried about sensitive data, keep it on an encrypted external hard drive. All someone needs to access any files on a hard drive is a $9 sata to usb adapter or a bootable thumb drive with linux or bart pe. Creating a password reset CD is a simple way to access the actual OS, and if the objective of the hacker is to create mayhem, there is nothing more irritating than your password not working.
Ultimately, I find Kon Boot very useful as an IT professional. When working on a clients computer I don’t have to go through the 10 minute process of resetting the password as it takes about 2 minutes to run Kon Boot and it returns to normal when the system is rebooted.

the easiest way to not let KON-BOOT load is by disabling it in the BIOS

*disable boot from a CD in the BIOS
*just make sure you password-protect the BIOS
*also put a lock so people won-t open the side of the case and remove the CMOS battery, disabling the BIOS password
*somewhat time is needed for this process but security is always good

Remove/reset lost Windows password you can use Windows Password Rescuer, it can reset/remove Windows 7/vista/xp/2008/2003/2000 password instantly.
