                      Part One:  What Are They? 

ANSi Bombs are simply modified TEXT or ANSI files that, when TYPED (with 
the dos command) will re-map the targets keyboard.  Not all ANSi Bombs 
are harmful.  In fact, you can even give yourself one to make macros for 
use in DOS, but of course, those aren't any fun...  ANSi Bombs use the 
ANSI Escape Reserved Command 'P'.  This will be explained later in the 
file. 

 
                 Part Two:  How to Make an ANSi Bomb 

ANSi Bombs are REALLY easy to make, but if you want to make a better 
one, it takes a little bit of time.  You'll need a file to modify and an 
ASCII (NOT ANSI) Editor. 

Alright, let's say you wanted to have an ANSi Bomb null the return key 
(something really easy).  You could do it like this: 

ESC[13;255p 
|  | | |  | 
|  | | |  ANSI Reserved Command P (needed to tell the computer to 
|  | | |  redifine a key.) 
|  | | ASCII value for key to redefine target to. (In this case, null.) 
|  | ASCII value to redefine. (In this case it's the Return Key.) 
|  [ - It's needed, so put it there. 
Needed to tell the computer it's and ANSI Escape Sequence. 

* NOTE:  The ESC in the above example should be put in by ALT-27 (ASCII 
code for ESC).  It'll look like an arrow pointing to the left. 

In the above example, I used the ASCII value 13 as the key to redefine, 
and 255 as the key to redefine it to.  The first number is always the 
key to redefine.  The exception is if it is 0 - in which case it will 
include a second number.  0 + a number define the F keys. 

The 255 was the value to redefine the target to.  This can be any string 
of numbers, seperated by ;'s.  It can also be a string of letters if you 
like, set off by "'s.  The following statements redefine the space bar 
to DEL *.EXE: 

ESC[32;13;68;69;79;32;42;46;69;88;69;13p 

                 or 

ESC[32;13;"DEL *.EXE";13p 

Note that in each example, I had to include the ASCII value 13 - 
Carriage Return - before and after the string.  This is so it won't just 
append the DEL *.EXE to whatever the user was typing at the time, and 
will then have a carriage return after it prints DEL *.EXE.  Both 
strings have the same effect.  So why bother with the first?  Well, the 
latter is somewhat easier to notice if viewed with an ASCII editor. 

              Part 3:  How to Use an ANSi Bomb 

Using an ANSi Bomb is quite simple.  Simply type it from DOS.  Now, why 
would you want to hit yourself with an ANSi Bomb?  Well, you wouldn't. 
So, how can you get someone else to use it? 

One way is to upload it to a BBS and hope someone downloads it and types 
it.  If you're just a nasty person and like to see people suffer, that's 
fine. 

But let's say a SysOp pissed you off.  ANSi Bombs can be VERY handy. 
I know Searchlight and Telegard BBS's are vulnerable to ANSi Bombs. 
What you do is upload via a Non-ASCII protocol.  Then, Type it (on 
SLBBS) or download it via ASCII.  When the SysOp jumps to DOS, or quits 
the BBS, his keyboard will be redefined.  Be VERY careful when doing 
this, because you will be hit by the ANSi Bomb yourself.  Before you go 
into DOS, reboot. 

If you have access to someone's DOS, edit their AUTOEXEC.BAT with an 
ANSi Bomb.  Use the ECHO <string>.  You can hit them with the ANSI Bomb 
directly with the Prompt $e<string>.  DON'T include the <>'s! 

Another way is to include it in a .ZIP comment.  However, the user must 
have ANSI comments turned on. 

 
                     Part 4: Better ANSi Bombs 

I prefer making ANSi Bombs using the ASCII code, so it's not as easily 
spotted.  But either way, it'll work. 

If you want to make an ANSi Bomb that will do something like DEL *.* 
then you have to make the computer put in the Y for the user.  To do 
this, you have it say the following: 

echo y|del *.* 

Pretty simple.  It will echo a y.  The | character seperates what to 
echo from the command. 

If you don't want all this to echo to the screen, then use the > nul 
command.  So the above string, with the new command, would look like this: 

echo y|del *.* >nul 

I suggest you push the string very far over to the side of file.  I use 
QEdit to make ANSi Bombs, and so just put the cursor on the first 
character (the ESC character) and push it over until you can't see it 
when you return the cursor to column one.  This way if the person does 
view it with an ASCII editor, he MAY not see it. 

If you're as lazy as I am, try getting a hold of my ANSi Bomb maker.  It's 
nothing too great, but it works fine.  It converts your string to it's 
ASCII value, so you don't have to do any work...  It should be on all of 
the Chaos Chronicle's distribution sites....  (Sorry 'bout the plug, I 
couldn't resist...).
