How to access stored user name n passwords with rundll32.exe?

The Stored User Names and Passwords applet lets you assign usernames and passwords to use when needing to authenticate yourself toservices in domains other than the one you are currently logged into. The normal way of running this applet can be difficult to find quickly,so here is a way to launch it using a desktop shortcut using the rundll32.exe program:

Click on START - RUN and type the following (follwed by ENTER):

rundll32.exe keymgr.dll,KRShowKeyMgr

How to recover/HACK Windows Password from Linux?

Friday, December 17, 2010

Anu

Check out this method for retrievingforgotten Windows passwords via Linux.

I works on Windows XP and Vista (not yettested on Windows 7).

Ingredients: one Linux live CD (that auto mounts Windows partitions – e.g. Ubuntu, Backtrack, Fedora, openSUSE).

Save the .iso and burn it to a disc.

Boot from the CD and follow these instructions (assuming your areusing backtrack, but should be similar for other Linux distributions):

Open a Linux terminal and enter the following commands:
cd /mnt
ls (make a note of the folders listed here. You might need them in the next step.)
cd sda1/Windows/System32/ (If this doesn’t work you might have thewrong hard drive: try replacing ’sda1? with sda2, hda1, or hda2)
mv utilman.exe utilman.old && cp cmd.exe utilman.exe
reboot (and remove the CD)
Once rebooted, at Vista or XP log in screen, press the Windows key+ U to run CMD with system privileges. Replace the username below withone of your choice – it must not already exist!
c:\ net user username mypassword /add
c:\ net localgroup administrators username /add
Log in with the new admin account!

Thanks..

How to recover linux password when GRUB is also locked?

Friday, December 17, 2010

Anu

I know tht you have the trick to recover/crack/hack linux password but did you also know tht how to recover linux password when grub is also locked or grub password is lost?
I have the answer...
The only essential thing is that you should have a Linux boot CD ofthe same operating system for which you want to crack root password.Some other Linux boot CD may work in some cases. If system is able toboot from the CD, it will take you to a command prompt as shown.

boot:

Type ‘linux rescue’ at this command prompt and enter as shown

boot: linux rescue [Enter]

It will take you to some interface with some questions, answer themproperly. The system will go to temporary command prompt. Then issuethe following commands

[bash$] chroot /mnt/sysimage [Enter]
[bash$] cd /boot/grub [Enter]
[bash$] vi menu.lst [Enter]

Now in this file you can see a line beginning with the word ‘password’ remove this line and save the file.

1 2	[bash$]exit [bash$]exit

Now system will be rebooted and you can see the grub without a password. Don’t forget to remove the CD.
Press ‘e’ at boot screen and again by taking the pointer to thesecond line press e. Now you can see yourself on a command prompt.Remove ‘rhgb quiet’ from there and write single and press enter.
Now you will come back to the boot screen. Press ‘b’ and system willappear to boot and leave you in command line interface like this.

-bash2-$

Just type passwd like this

-bash2-$ passwd [Enter]

new password:
retype new password:
passwd: All authentication updated successfully.

Now you have set a new password. Now exit from the shell and system will boot properly in graphical interface.

-bash2-$ exit [Enter]

If there is any error in the procedure please post your suggestions.

How to recover Linux root password?

Friday, December 17, 2010

Anu

Hi friends, here is a way to recover your Linux (all distributions) password when you accediently forget it...
To get around a lost Linux root password:
You must have access to the console for this to work. Follow these steps:

Power off the system
Power on the system, wait for the LILO/SILO/MILO prompt (platform dependent)

(For more information about LILO/SILO/MILO : OR : More information about boot process of Linux as well as Windows :
First :1: Second :2:)

Depending on how lucky you are, or rather how ancient your linuxdistribution is, you might be able to get away with the following:

At the prompt, type <kernel> 1 (where <kernel> is the label you use to boot linux normally) and thus boot to single user mode.
In single user mode, linux never used to prompt for the superuser password. If this is the case with your system, simply use mount -o remount -n / and then use the passwd command to change the superuser password.

If you're blessed with a somewat more secure system, you need to do this:

At the prompt, type in <kernel> init=/bin/sh (where <kernel> is thelabel you use to boot linux normally).
Once the system dumps you at a "# " prompt, type: mount -o remount -n /
echo root2:x:0:0:::: >> /etc/passwd
echo root2:::::::: >> /etc/shadow
sync
Power cycle the system.
Once the system has booted, log in as root2 (you shouldn't be prompted for a password) and use the command passwd root to change the root pasword,then userdel to remove the root2 user.
Problem solved.

There are of course many variations on the linux version. For example, you could edit /etc/shadow directly. This requires knowledge of text editors such as ed (most of the time, you won't have a normal terminal when you boot like this and vi won't work!) which may or may not be an unreasonable expectation.

Thanks....
