Puppy Linux XP Password Cracker

Im thinking of more ways to get people to try puppy...

One of the main ways Ive seen a virus or a hacker brick a XP computer is to change the login passwords. I get called out often to remove or change the passwords (I think windows password can be said to be more of an inconvenience than a security measure!). For this I use the ophCrack live cd, which is based on slax and 455mb big. This is basically a custom livecd distro with nothing but the cracking software preloaded. Ive found it also boots on less computers than puppy, and it also doesnt recognise certain hard disks. Puppy does a lot better. I think in the situation that this cd would be used would be an ideal time for people to take their first look at puppy/linux, just when XP has failed on them! Using a puppy cd would also allow the client to view their files while xp was being cracked (it takes about 5 mins).

If someone were to create a puppy cd that included ophcrack, then I think it would create a lot better product (Im a bit busy now what with everything, but would be happy to help test it and provide feedback).

" Ive found it also boots on less computers than puppy, and it also doesnt recognise certain hard disks. "

Sometimes the older version released earlier this year boots and finds
the passwords better than the later ophCrack.
And yes sometimes it just stops.

Good idea ...............add a GUI as well.
Combine this with some Ultimate Boot CD features and what a cracker....literally....version of Puppy that would be.

Some of the " Ultimate" lads use Puppy as well.
And I am sure of them some lurk on this forum.

Rudy Puppy had extra tools as well?

I Forgot My Administrator Password! by Vic Ferri

Can't Log On to Windows XP?

If that’s your only problem, then you probably have nothing to worry about.
As long as you have your Windows XP CD,
you can get back into your system using a simple but effective method made possible by a little known
access hole in Windows XP.

This method is easy enough for newbies to follow –
it doesn’t require using the Recovery Console or any complicated commands.
And it’s free - I mention that because you can pay two hundred dollars for an emergency download of
Winternals ERD with Locksmith which is a utility for unlocking lost Windows passwords.
See here http://www.winternals.com/products/repa ... ksmith.asp

ERD is an excellent multi purpose product, but you should know it is not a necessary one if you have a healthy system and your sole problem is the inability to logon to Windows due to a forgotten password. Not necessary because you can easily change or wipe out your Administrator password for free during a Windows XP Repair. Here’s how with a step-by-step description of the initial Repair process included for newbie’s.

1. Place your Windows XP CD in your cd-rom and start your computer (it’s assumed here that your XP CD is bootable – as it should be - and that you have your bios set to boot from CD)

2. Keep your eye on the screen messages for booting to your cd Typically, it will be “Press any key to boot from cd

Chris good one, mate.

BTW ERD/Winternals is now part of the dreaded Borg empire. Microsoft bought them about a year ago

So for $200 you'll pay a lot more for less imho. Less? Yep they advised mid 2007 that certain parts of the ERD CD were not going to be included in ther next version

Thanks for the F10 tips as well.

Ooroo,

Richard downunder

There's a "puppy unleashed" type system for windows called "Bart's PE Builder". It allows you to build a customised ERD type CD.

On the linux side of things there is the Ophcrck live cd.

The ophcrack LiveCD contains a small linux system (SLAX6), ophcrack for linux and rainbow tables for alphanumerical passwords.

The liveCD cracks passwords automatically, no installation necessary, no admin password necessary (as long as you can boot from CD).

Windows Vista SAM can also be cracked.

I'm sure we can reproduce this effort in puppy.

Hi lads new to this I have ophcrack installed on my puppy if anyone is looking for it, I have used it and havent had a problem with it

Lobster · #7 Post by **Lobster** » Fri 23 Jan 2009, 15:50

I am not sure if they still have it or what they used but Austrumi used to have this XP password cracking facility built in . . .
Thought it might be of interest

They still have something called 'hydra'

That's a classic. Copying out the encrypted SAM is a good idea.

so ophcrack can be installed on puppy for definate? Ive just downloaded the source code, which is quite small (225k), I dont know how big a package that this would translate into, I dont know anything about compiling.

Here ya go I compiled it both ways commandline or the Qt4 GUI version.
command line type in a terminal
ophcrack
and the QT4 version install
http://puppylinux.ca/puppyfiles/pet_pac ... -4.3.2.pet
to run it, install the pet, install the QT4 libs from above, fixmenus <-- in a console
the restart JWM or Icewm
go to menu/utility/xp password cracker <--- click and enjoy

FYI. What allows ophcrack to crack windows passwords 'quickly' is the rainbow tables are that included on the cd. The rainbow table set included in ophcrack is limited and can only be used with certain passwords. To be able to crack (or rather look-up) any windows password the entire table set would be needed which is gigabytes in size.

If we are looking for the same speed as ophcrack we would need to make the rainbow tables available on the puppy cd as well.

I didn't know, I just read that he need it a application compiled and I compiled it, I didn't read up on it, LOL did you check out the vista 9 52GIGS of tables ya ok how would you move that around and how long would it take? maybe a portable hard drive.

Ophcrack would work fine without the tables but it will be via bruteforcing the password. The time to crack a password via bruteforce could be better spent after resetting the password via chntpw.

Ttuxxx, thanks for compiling this. I must confess I dont have a use for this myself (I generally just boot puppy, copy the data off to an external hard drive and format with gparted

), but I know it would make a great tool for many of the other poor failing xp technicians in my area, and maybe help bring them over to linux.

How does the ophcrack livecd deal with these rainbow table thingies?

Ive just tried this package on Puppy 4.2 Beta 1 and it installed fine, but I thankfully dont have any xp installations to test it on!

Would it be possible to remaster a puppy version with this built onto it? I could post a link on the ophcrack forums and get them to work on it. The size of such a remaster would be a quarter of the size of their current offering, and would offer a full operating system environment as well!

well yes you can remaster with it, might as well install the other I compiled to, that was small also,
When you run the remaster script and it ask you check
/tmp/root/
go to /tmp and delete root, then copy the real root folder to /tmp and you'll have a 100% copy. if you don't sometimes you lose things like browser addons/themes setting for other programs etc.

always boot up with
puppy pfix=ram before, so none of your settings or passwords will be copied. If you log into your email say, and then you remaster, theres
a good chance that you'll be giving everyone you email account already logged in

So run live and run clean. keep your addon pet files locally hard drive/USB stick etc. just install them and remaster. don't even bother going online or anything. Sometimes internet settings can be copied over to and that complicates things, so always
puppy pfix=ram

Landed here from Google and i am looking for a way to reset my puppy linux password. Any alternative to Ophcrack? thanks

rockedge · #18 Post by **rockedge** » Fri 29 Jul 2016, 06:54

To change the root password:

open a terminal and type "passwd"

Code: Select all

#passwd

is this what your looking for?
