00100: Fucking Up Dos!
By: digitalboyOk now, say you want to screw a computer. Or maybe it's your school
network you want to destroy. Most of these systems are run on a dos-based
network anyway, because the teachers that administer them are fucking idiots
who don't even know what UNIX is. Anyway, there are a couple fun ways to
wreak havoc on Dos-based systems.
NOTE: I got a lot of the info for this file from a text by hypertheif. Greetz
to him fer bein so damn smart =).
STEP ONE--> Controlling the BIOS...
This is extremely important. If you can't get control of the BIOS you
can't stop them from using a boot disk, which makes your efforts basically
useless. Most teachers are smart enough to put a password on the BIOS.
Instead of wasting your time trying to guess the password, you can use two
methods to reset the bios and therefore own it.
METHOD ONE: The Debug Script
Debug is a great utility. You can fuck with most anything using debug,
including the BIOS. Debug can reset the BIOS, just use this simple script...
debug
-o 17 70
-o 17 71
-o 70 17
-o 71 17
-q
I hope you know how to use this. If you don't go get a dos manual and
start reading. The only problem here is that on old computers important stuff
like the hard drive isn't autodetected. See, this script RESETS the BIOS.
COMPLETELY. So you have to manually set it up. It would be a good idea to
have an idea of what the hardware specs of the system are.
METHOD TWO: Pulling The CMOS battery
This is for those of you resorting to more desperate measures. To
accomplish this, you have to open up the box and pull out the battery. Get
out your manual and open up your computer first to see what it looks like.
The BIOS is saved in CMOS memory, which is powered by this battery. When you
take it out the BIOS is reset. This can't be done on some systems because the
CMOS battery is hardwired to the motherboard.
Once the BIOS is reset, reboot the computer and get into the BIOS. First
thing to do is set your own password. Don't make it something simple. If
possible, make it something that even you would forget. That way if they find
out it was you just say you guessed theirs and forgot your own =). While
you're in the BIOS, disable the floppy disk drives. And if it has the boot
order option, change it from A,C to C,A or C only if possible. That way, they
can't use a boot disk and get past all of your "enhancements". This is
basically all you will want to do with the BIOS. You can go through and mess
with other things, but these are the important ones.
STEP TWO--> Autoexec.bat and Config.sys
There are some modifications that should be made to these files. We'll
start with Config.sys first. Go in with edit and add the line
"switches /n /f" at the beginning of the file. This will keep them from
pressing F8 or holding Lshift to bypass the startup files. You also should
take out any drivers that aren't really necessary. An important one is the cd
driver. The line for the cd driver usually has the string "MSCDEX" in it
somewhere. That way, they can't load up a Windows 95 cd and install it,
fucking up your minutes of hard work. Now for autoexec.bat. You can have a
lot of fun with this one. First order of business is to add "ctty nul" to the
top of the file and "ctty con" at the end. This gives control of the terminal
to a nul port and away from the keyboard. This keeps them from CTRL+BREAKing
out of the batch file. Actually, ctty con is optional, you could just send
control to a null port and not give it back. Also, add a few fun ECHO's to
the autoexec file. Just to let them know how dumb they are. If you're really
creative, write a small Pascal or C file that loops endlessly and taunts the
people sitting at the keyboard. If you're gonna fuck with them, you might as
well make it fun.
STEP THREE--> Basic Dos Destruction
You want to make everything as difficult as possible for the people trying
to get into the system and fix it. Hex editing command.com is a good place to
start. Find the text strings for all the dos commands and change them. Make
sure you keep the number of letters in each command the same so you don't get
the "corrupt or missing command interpreter" message. Another thing to keep
in mind is that if the command is in capitals in the file, keep it in
capitals, and vice versa. This will completely disable dos. Think about how
hard it would be to do anything without the CD and DIR commands. Next, go
into the dos directory and delete all the extra dos commands in there. This
pretty much screws them over, but there are some extra things you should do.
First rename the dos directory and the windows directory to names with a
space in them. This is easy to accomplish. Say you want to rename c:\windows
to c:\fuck me. Type "ren c:\windows c:\fuck[alt+2+5+5]me". That's hold down
ALT, press 2, press 5, press 5, and let go of ALT. This makes a directory
that windows won't recognize and can't read at all. Fun for you, aggravating
for them. While you're at it rename the win.exe file and anything else you
might want to "fix".
STEP FOUR--> Enhanced Dos Destruction
This section isn't for general mayhem. You can really fuck stuff up here.
In other words, read on =). A quick way to corrupt the hard drive is to run
fdisk and delete the primary dos partition. Then, when it sez to press
CTRL+ALT+DEL to reboot, Press CTRL+BREAK or CTRL+C to exit the program. This
will empty the hard drive of anything useful. Some less mild forms of
corruption are to start either reformatting or defragmenting the hard drive,
then reboot during the process. This will corrupt areas of the hard drive and
render them unfixable. Of course, you could simply deltree of reformat with
these commands, but you would be succumbing to the less artistic forms of
computer terrorism.
STEP FIVE--> Satanic Dos Destruction
Ok, you must REALLY want revenge. These are just some ideas i have come up
with for completely disabling a computer. We all know the havoc magnets can
wreak with electronics. We all have those thin little fridge magnets around
the house. Now i want you to think hard and imagine what we can do with
these. Casually sit down at one of the computers. If you have one assigned to
you, DO NOT sit at this one. Sit at someone elses. This is a good rule for
all of the steps discussed above. If you can get to the server, prepare for a
few days off of school. Anyway, bring a few of those little magnets. Turn the
computer off. Slide one around inside the disk drive. Slip a few inside the
vents on the top of the monitor and inside the computer. You just destroyed
that machine. If you can, take out the keyboard plugs and mouse plugs from
the back of the computer. Get some needle nosed pliers and pull out a pin or
two. Find the little key that locks the computer. Saw almost all the way
through it, then take it back to school and lock the computer. Then break off
the key in the lock. If your school relies on boot disks like mine, get a
bigger magnet and run it over the tops of all the boot disks. Presto, a box
of corrupted boot disks. Glue is another alternative, i'm sure you can think
of your own ways of using that. Note that you can do this to computers in
stores too. Big stores that can afford it and overcharge should be your prime
target.
STEP TWELVE--> Silly Little Annoying Things
All of the above stuff might seem a little extreme to some of you. If you
just want to play with someone, there are a few things you can do to mess
with them. One fun way to annoy and confuse the hell outta people is to
create a buncha doskey aliases under the names of the program's they run,
making the aliases run other programs. Dos looks in doskey for commands
before it looks on the hard drive, which means you can make an alias for any
program that runs another one. Read up on doskey for methods of doing this.
If they have windows 95, do this with all the stuff on the start menu. Change
what each icon runs, or delete the start menu all together. Go into the
control panel and change their virtual memory options. Tell win95 to let you
specify your own settings and make it as big as possible. This will quickly
fill up their hard drive and they won't have a clue what is going on.
THE TWO THINGS YOU BETTER FUCKING REMEMBER:
1--> DO NOT...i repeat DO NOT let ANYONE see you doing this. They will rat on
you. It's a fact.
2--> DO NOT...once again DO NOT tell ANYONE what you did. Poeple LOVE to
talk. They will tell ANYTHING to ANYONE. Trust me. No, don't, don't trust
anyone. You will end up caught.
MERRY MAYHEM......By the way i'm not resposible for any shit you get into
usin this file. It's meant for (bwaaahahahaaaa) study only, not to use.
Really it isn't. Hey, where are you going. What are you doing with that jar
of battery acid. Don't you DARE touch that keyboard. Oh well, it's yer own
fault if you get caught....just make sure you tell me what you did =).
