Changing your Grades!

If you hate school and you have very bad grades you can always learn how to hack the system and change them or cause havoc. Also, a teacher or someone that you dont like may have pissed you off you can use this to get back at them. I will also show you how to change other students grades so they fail and have to repeat the grade over again! Lets begin.

Passwords

First, you need to get the Administrators password. This is very easy if the computers are Windows 95 or 98 because they store the passwords as .pwl files in the C:windows directory. If this is so, get a floppy disk and go to Start > Run and type copy C:windows*.pwl A: without the quotations. Another way of getting them is to go to Start > Search > Find files or folders and then type in *.pwl in the search field without the quotations. Using the Run command stated earlier should store all of the password files of everybody who logged on to that computer on a disk. There should at least be one password and most of the time the administrators password is included. Another way of getting passwords is to download @Stake L0pth Crack 4.0 from http://www.L0pht.com . The newer version of it is called @Stake LC4. You can burn it to a CD or put it on a disk, and then when you put it on a computer at school you can sniff passwords from the network. Going back to the PWL files, once you have them you will need to crack them so you can get the password. I think that the best PWL cracking program is CAIN 1.5 from http://www.confine.com . You will need to learn how to use this program and also you will need to get a wordlist for the program. A wordlist is a file that has multiple words that is used to crack the PWL file. It works by running all the words in the wordlist (Or dictionary file) by the password in order to find a match. Once a match is found you have the password!! Also note that the bigger your wordlist is, the greater your chance is for recovering a password. Once you have a password you can log in. On most systems at school there are 3 types of logins: Administrators, Teachers, and Students. The best thing to do is to find an administrator or teacher account because then you have more power. This is so because some websites may be blocked for students, but most of the time teachers and administrators have unlimited power. They also have access to grades and other cool stuff such as your discipline file! When you get a PWL file to crack you must enter the full name of your teacher. We will use the name Mike Davis as an example. The PWL file may be in the layout of mdavi.pwl well you know your teachers first name is Mike and their last name is Davis. If you look at the PWL file you will note that part of the last name is cut off. When you are in the CAIN program you will have to finish the last name. So in CAIN you will type Mdavis as the full username. Then begin the cracking process. If you need help on how to use the program a help file comes with it. Also remember that password cracking can take quite a while!!! For maximum results leave your computer on for 2 days. If the password still isnt there use my other method.

Logging in

Once you have a password and an Admin or Teacher account you can log in to the system. Just log in like you normally would on your own account, but instead use the password and username you got from the PWL file. Once youre in the system you can go in your teachers files and look around. If you got Admin that is very powerful and you can access every teachers file from that! Admin means that you have full control of the system using Admin you can even delete the principals account or see whats on his or hers computer!

Hacking the School

Hacking a school can be very easy or very difficult depending on what you want to do. In this section I will show you how to make your own Administrator account so that you will be able to log on using your own information. First, to make your account you need to make another batch file, and then you need to be logged on as an administrator. After that type the following code to make as a batch file without the quotes:

@echo off
net user username password /add /expires:never
net localgroup "Administrators" /add username
net localgroup "Users" /del username

Using this will create you an Administrators account. Just dont tell anyone about it! You can also use this to delete other peoples profiles. For example, Windows XP comes with the Remote Desktop program. Using that on your schools network allows you to be able to connect to the server if its running Windows 2000 Server. From there you can use the administration programs in the start menu. The best program I think of using is the Active Directory Users and Computers because using that you can create and delete accounts, assign passwords, disable a users Internet access, and get other information. When I used the program I was able to get phone numbers and addresses because they were entered along with the students accounts. There are about 20 programs, which you can use to control the network from there. I once ran into the firewall computer on the network. Using that, I gave myself all access to everything, I was also able to limit what other people could do on the Internet. Finally, if there is a teacher (including the principal) or student you dont like you can delete their passwords and suspend their account so they cant log in. Assuming that you are logged in as Admin lets now begin to talk about how you can change your grades! J

Changing Grades

Changing grades is very easy. First of all, if you want this to work the teacher must store the grades on the network. If you see them saving it to a disk that will mean this trick wont work. If the grades are on the network you must first find out what program your teacher uses to store and edit them. For example, at my school the teachers use Grade Machine. Once you find out what program they use for grades you need to see if it is installed on a computer somewhere that you can access. Most of the time grade programs are stored on all of the computers just like Microsoft Office is. Moving on, if you found the grade program start it up then look for your teachers account (this will only work if youre Admin). An easy way to this is to go to Start > Search > Find Computers and then type in without the quotations. This will show all the computers on the network. Before you do anything you need to be familiar with how the network functions. After this, find the main computer, which might look something like this NameofSchool Once you found the teachers account open the folder, and search for the grade file for your class then open that. Once the grade file opens you may (very rarely) run into the grade program asking for a password. When this happens try to enter the same one that you used to log on, if that doesnt work youre screwed so delete that grade file to get back at the teacher, but most of the time teachers dont put passwords on their grade files and if they do they use the same password as their logon because some of them are stupid. Finally, begin altering your grade! While doing this use common sense dont give yourself all As if you are dumb or you cant prove it. Also, while changing your grades you can mess up someone elses whos in your class while you change your own! Another way to change your grades is to hack the counselors office directly. This will require an AS/400 database (you know when they have their computer screens with all the green writing on it.) I suggest going to http://www.google.com and searching for some information on it. You must be very good with computers in order to do this and using this technique you can alter your report card and change your transcript, and its much more powerful that the technique I just showed you. But either method both works just fine! Keep up with this file and give it to everyone you know just give me credits!!!!!! By the way never tell a teacher about this because then they will change the whole system and no one will be able to change their grades. Pretty soon, teachers will begin to realize that students can demagnetize their disks with the grades on them hehehe!! Moving on, I will now show you how to #*@! up a computer system!

Batch Files

Batch files are very important files. To make them you can use the notepad program once again. If you are good with DOS then you should be very good making batch files because they are centered on DOS. For a list of DOS commands and examples of how to use them go to http://www.computerhope.com/index.htm and look around for their DOS commands. Anyways to make a batch file that will destroy a computer use the code below. To save the batch file, click on Save As and save it as Anything.bat without the quotes. You must type .bat for batch files. The code for the batch destroyer is:
cd
del c:*.*
y

Doing this will cause the whole entire hard drive to be deleted, which will also render the computer useless.



E-mail

Most teachers have an email account probably with the school. What more fun thing will it be to use their E-mail account to send a bad message to someone you dont like and make it look like it was them!! The trick to this is that most teachers passwords for their login are the same as their password for their E-mail. All you have to do is find out how they get their E-mail and try to get into it. Finally, after that send all the messages you want! In conclusion have a lot of fun hacking and screwing with school computers.
