Gain admin access on windows system using your guest account

Ever thought of how to get into your friend’s system and see the access denied files and folders? Or ever wanted to hack into someone’s admin account? Well here is a method which exploits yet another windows bug.

  1. Have you ever noticed that if you press your system’s SHIFT key >= 5 times continuously a pop up windows occurs with the name “Sticky Keys”? If it doesn’t pop up on your comp, then may be your shortcut is turned off. For enabling it, gotoControl
    Panel -> Accessibility Options. In the accessibility options under the
    keyboard tab, in sticky keys , click on settings and enable the
    shortcut for sticky keys. And u can do this even with a guest account.
  2. Finally if the following 2 requirements are setup on your system, then you are all set to enter into your admin’s account.
  • On Pressing SHIFT >= 5 times, a pop up should appear.
  • The windows System32 directory should be writable.

Concept:
When u press, the SHIFT key >= 5 times, a file with the name “sethc.exe” is
executed.  You can verify this in TASK manager (don’t close the pop up
window). This file is located in C:\WINDOWS\system32 folder, or
where ever your windows is installed.

The Vulnerability

  1. When SHIFT key is pressed >=5 times, windows executes a file named
    “sethc.exe” located in system32 folder. It doesn’t even check if its the
    same file. Also it runs with the privilege of the CURRENT USER
    which is executing the file i.e if u have logged on as a guest then in
    the TASK manager under processes, it shows your user name as guest.
  2. The file executes even if u log off, and have the windows login screen is
    showed up, BUT THIS TIME SINCE NO USER HAS LOGGED IN IT RUNS WITH
    SYSTEM PRIVILEGE.

Exploitation
If u understand this much, then the exploitation is very simple for you. What we will do is that,
we pick cmd.exe , copy it at a folder other than system32, (because windows
won’t allow u to copy) rename it to sethc.exe, go to system32 folder,
and paste it. Windows will ask, “that another file exists, do u want to
replace?” and after pressing OK, you have replaced the sethc.exe with ur own
cmd.exe. Now if u press SHIFT key >=5 times, a command prompt will
pop-up.


Finally

  1. Now log-off or restart. When you reach the windows
    login screen, press the shift key >=5 times. A command prompt will
    pop up with SYSTEM privilege.
  2. Enter the normal commands as follows:
  3. net user username /add
  4. net user localgroup administrators username /add
  5. And a new user called username with admin privilege will be added.

And thats it, you have admin privilege of the system and you can do what ever you want to with it.

Hiding your fake admin profile
Now you surely don’t want the real admin to track you. Here is what you will have to do to hide yourself from login screens as well as from control panel

  1. Goto registry editor and open this place.
  2. [HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon\SpecialAccounts\UserList]
  3. Here create a new DWORD value, write its name as the “user name” that u created for your admin account.

Thats it now you are invisible but still admin of the system. Live as admin forever and keep screwing the real admin forever.



Last but not the least (IMPORTANT)
Windows has two type of login screens:

  1. Where the accounts are listed with some pictures.
  2. Where u have to write username and password.

After making the hidden account u will have to login through the 2nd step only. If ur login screen is of Type 1, press ALT-CTRL-DEL twice to get the 2nd type screen.

Thats it!!!


NOTE:
This is a sureshot way to gain admin, if u r a lamer or a newbie
then please do some googling.
I have written almost every detail.

Thanks for reading this far :) Make a comment if you liked this one.

Thanks for digging and shouting it out to your friends.

Windows XP Tricks !!

Shutdown XP Faster
 

Like previous versions of windows, it takes long time to restart or shutdown windows
XP when the "Exit Windows" sound is enabled. To solve this problem you must disable this
useless sound.
· Click Start button.
· Go to settings > Control Panel > Sound, Speech and Audio devices > Sounds and Audio
Devices > Sounds.
· Then under program events and windows menu click on "Exit Windows" sub-menu and
highlight it. Now from sounds you can select, choose "none" and then click Apply and
OK.
Now you should see some improvements when shutting down your system.


  Turn Off System Restore to Save Space


By default, Windows XP keeps a backup of system files in the System Volume Information
folder. This can eat up valuable space on your hard drive. If you don't want Windows to
back up your system files:
· Open the Control Panel.
· Double-click on System.
· Click the System Restore tab.
· Check "Turn off System Restore on all drives".
· Hit Apply.
· You may now delete the System Volume Information folder.
Warning! If you turn this off you will not be able to use Windows System Restore to
restore your system in case of failure.
 
Correcting System Hang at Startup
 

If your system hangs about 2 or 3 minutes at startup, where you can't access the Start
button or the Taskbar, it may be due to one specific service (Background Intelligent
Transfer) running in the background. Microsoft put out a patch for this but it didn't
work for me. Here's what you do:
· Click on Start/Run, type 'msconfig', then click 'OK'.
· Go to the 'Services' tab, find the 'Background Intelligent Transfer' service.
· Disable it, apply the changes & reboot.








Disable XP Boot Logo  

It is possible to disable the XP splash screen, which will slightly speed up the
overall boot process. Be aware that removing the splash screen will also cause you not
to see any boot-up messages that might come up (chkdsk, convert ... ), but if your system
runs without any problems then it should not matter.
· Edit boot.ini.
· Add " /noguiboot" right after "/fastdetect".
Upon restarting, the splash screen will be gone. It can be re-enabled by removing the
new switch.


Remove Hibernation File
 

If you do not use hibernation, make sure you do not have it enabled, which reserves
disk space equal to your RAM. If you have a hidden file on the root directory of your
C-drive called hiberfil.sys, hibernation is enabled. To remove that file:
· Go to Control Panel, select Performance and Maintenance, Power Options, Hibernate
tab, and uncheck the Enable hibernation box.
 

Performance Increase Through My Computer
 

Easy enough tweak to usually find out about it on your own, but still, some of us
still don't find it right away. So here it is:
· Start > right-click on My Computer and select Properties.
· Click on the "Advanced" tab.
· See the "Performance" section? Click "Settings".
· Disable the following:
Fade or slide menus into view
Fade or slide ToolTips into view
Fade out menu items after clicking
Show Shadows under menus
Slide open combo boxes
Slide taskbar buttons
Use a background image for each folder type
Use common tasks in folders
There, now Windows will still look nice and perform faster.
Reduce 10 Second Scandisk Wait Time
· Start MS Dos Prompt (Start run CMD), and type: CHKNTFS /T:4
where 4 is the amount of wait time.
CHKNTFS /?
for more info.
 

DMA Mode on IDE Devices
 

Just like Windows 2000, Windows XP still fails to set the DMA mode correctly for the
IDE device designated as the slaves on the primary IDE and secondary IDE channels. Most
CD-ROMS are capable of supporting DMA mode, but the default in XP is still PIO. Setting
it to DMA won't make your CD-ROM faster, but it will consume less CPU cycles. Here's
how:
· Open the Device Manager. One way to do that is to right-click on "My Computer",
select the Hardware tab, and select Device Manager.
· Expand "IDE ATA/ATAPI Controllers" and double-click on "Primary IDE Channel".
· Under the "Advanced Settings" tab, check the "Device 1" setting. More than likely,
your current transfer mode is set to PIO.
· Set it to "DMA if available".
· Repeat the step for the "Secondary IDE Channel" if you have devices attached to it.
Reboot.
