Ethical Hacking Tricks

Shutdown Trick !

Imidiate rapid shut down window
while shutting down window. open task manager(Ctr+Alt+Del),
Select shut down tab. and press ‘ Ctrl ‘ key while select Turn Off from dis tab.
Count 5 4 3 2 1 Voila!!! U r window will rapidly shut down.

 

 

Hide ur folders.. never known trick !!!!!!!!!! Disguise them to “Recycle Bin”

Rename any folder with extension {645FF040-5081-101B-9F08-00AA002F954E}

eg,
if u’ve a folder games
press F2,
then type, “games.{645FF040-5081-101B-9F08-00AA002F954E}”
c the magic….
then 2 get to original form,
remove the extension using
“ren games.{645FF040-5081-101B-9F08-00AA002F954E} games” in dos or as a bat file

and you are done..

 

 

System information

 system up time only for xp professional edition

It boasts how long it can stay up. Whereas previous
versions of Windows were coy about how long they went
between boots, XP is positively proud of its stamina.
Go to the Command Prompt in the Accessories menu from
the All Programs start button option, and then type
‘systeminfo’. The computer will produce a lot of
useful info, including the uptime. If you want to keep
these, type ‘systeminfo > info.txt’. This creates a
file called info.txt you can look at later with
Notepad. (Professional Edition only).

 

 

Remove Stored username and Passwords !

To remove the Stored User Names and Passwords from your system, try this:
Click Start, Run and type Control keymgr.dll
Remove the entries from the list.

The other ways to access this dialog are: 
Type Control Userpasswords2 in RUN box, click Advanced, Manage Passwords 
-or- 
From Control Panel, select your User Account, click Manage your network passwords.

Faster, more secure logins for multimedia sites might be possible thanks to a new approach to website and database security. Boolean logins would allow thousands if not millions of users to more quickly access the content to which they are entitled, such as music, video and images. The same approach might also reduce the risk of hackers accessing the materials illicitly.

Classic user identification requires the remote user sending a username and a password to the system to which they want to be authenticated. The system looks up the username in its locally stored database and if the password submitted matches the stored password, then access is granted. This method for identification works under the assumption that there exist no malicious users and that their local terminals cannot be infected by viruses.

Increasingly, however, these assumptions are too naïve. Not all users can be assumed to have good intentions. Technology continuously facilitates the capture of transactions in wireless channels. Usernames and passwords can therefore be easily obtained by malicious third parties (other users or viruses) and be used for illegal accesses to systems.

The system is based on a set of relatively simple mathematical functions, known as one-way Boolean operators, to verify a login rather than the standard encryption-decryption calculations used today. The team explains that preliminary testing shows that their approach to a login algorithm could be hundreds or thousands of times faster than conventional logins. Importantly, the system will reduce the overall computing requirements on the provider side of the system as well as making logins much more secure.

Zero order user authentication schemes supply the user with a special function that produces an extremely large number of different results for all its possible inputs. A set of inputs that produce a common result is selected. These inputs are the user’s passwords. A new user registers by submitting to the system their function and the common result. The user authenticates for a normal session using each password only once. The user provides the password at the beginning of each session. The system calculates the value produced when this password is used as input to the function. If this is equal to the common result, then authentication is successful and access is granted. Someone that is trying to gain access without the necessary knowledge (an illicit user) will practically have to try all possible password combinations, before reaching the correct one.

Normally, the functions used involve raising large numbers to large powers and dividing large numbers to find their remainder. These are operations make processors of ordinary computer systems run very slow and impose a significant burden even on larger information systems with large numbers of users. The proposed scheme uses systems of non-linear Boolean equations to construct the unique function. Boolean equations process binary data, using simple binary operations between bits. Such an operation is the eXclusive OR operation (XOR). Calculations are hence much simpler for the simple reason that it is much easier to calculate a logic expression than to raise a 100 digit number to a 10 digit power and then divide the result by another large number. The series of exchanges for registration and authentication is the same as before. However the inputs and the common results are binary vectors.
