             - HOW TO GET INFECTED FILES INTO LAME BBS's -

    Ok, one problem with sending infected files to BBS's is that you never
can tell if they will be detected by SCAN.  Or if you are sending bombs
the sysop might use CHK4BOMB to detect code that is data damaging.

I'm gonna tell you how to get around this, what you need is the following-

                            PKLITE or LZEXE
                                  and
                           A good hex editor

What you do is this, compress the infected file with Pklite or Lzexe.  This
will make change the files checksum and ID strings quite a bit so it can't
be detected by SCAN and damaging data will not be found by CHK4BOMB.  The
problem is that now the sysop can use CHK4LITE to detect is the file is
indeed infected.   So what you do is this --

Load up the hex editior -

Now look at the file, it will look something like this if you compressed it
with PKLITE.

You see the header?  Well what you have to do is overwrite the header with
garbage.  Don't write text cause that is to dectectable by a dump program.
Just overwrite the part that says "PKLITE corp....Reserved" with hex bytes.
Also distroy the part of the code that says "Not enough memory", dont kill
the "$" symbol.

This will make the compressed file-

A> Undetectable to virus scanners, and CHK4BOMB type programs
B> Un-Decompressable
C> CHK4LITE wont notice it as a PKLITE file

It's that easy!

Keep in mind however than any file that the virus infects will no longer
be encrypted by PKLITE, so this method is good only on getting your virus
into the front door.

See the article in issue one on making new virus strains.


                                Forenote

After writing this article SCAN Version 80 came out, It now has the
ability to scan into Pklite compressed files.  Just to let you know that
this teqnique still works and SCAN cannot detect the file as being
compressed as PKLITE.

                                                                         HR

                THE SAFE WAY TO EXPERIMENT WITH VIRUSES

The problem with fooling around with viruses is that you never know
what damage there going to do to your hard disk.  I have a couple of
so called viruses that when run, automatically screw up the FAT on
all the disks in the system.  Well, theres a way around getting the
shaft from these programs, and also to experiment with legitament
viruses.

The key is the DOS utitlity SUBST, make this batch file, and copy it
to a floppy.

----------------------------------------------------------------------------
@echo off
subst d: a:\
subst c: a:\
----------------------------------------------------------------------------

What this will do is send any access to disks C: and D: (the two
hard disks in my case) to drive A:  So the only damage inflicted
will be to the floppy in A:

No programs can access you hard disk when this command is issued.  I
use it all the time and as of now it has proved 100% safe.

Oh yeah, if you dont feel like distroying a floppy every time you
mess with a virus, you can do this teqnique from a RAM disk.

Have fun...

Virus Spreading - Fast Or Slow?               By Nick Haflinger -=PHALCON=-

Call The LandFill BBS (914) Hak-Vmbs
-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-

     One of the questions while writing your virus is how quickly you want
it to spread.  The easy answer is "As fast as possible" but this is not
always the best answer.  If a virus moves slowly, it will take much longer
before somebody notices hard drive space disappearing, he/she will notice
fewer changes to the file dates, and all other symptoms will be lessened.
However, this does provide longer for anti-virus people (pronounced Scum,
with a capital S) to discover the virus.  This issue ties directly into the
issue of activation, short or long.  Since the issues are virtually
identical, I will cover both together, because they are so closely tied.

                        The Case For Fast
                        +++++++++++++++++

     Viri should spread as quickly as possible.  This allows as little
time as possible for the makers of antivirus programs to come up with an
antidote before the virus is widely spread.  This should be tied with a
short activation period to cause as many problems as possible before
detection is possible.  Because fewer copies are generated before activation,
each copy may be larger.  This allows for more extensive anti-anti-viral
tactics, which are becoming increasingly more important as the number of
anti-viral products rises.  Just remember, most of these products are shit.
So don't worry too much.

                        The Case For Slow
                        +++++++++++++++++

     Viri should spread slowly, because this is less obtrusive, and therefore
users are less likely to notice a change in the system.  This should be
coupled with a long activation period as to have maximum penetration before
the virus activates.  A slow-spreading virus will circulate to more virus
programmers who will be able to modify the program for specific needs or to
adapt to antiviral tactics.  On a purely academic note, slow spreading viri
must be smaller, as more copies must be generated.  This means that viri must
be programmed better, which is good for the general community.

                       The Case Against Fast
                       +++++++++++++++++++++

        Fast spreading of viri is likely to draw attention.  Once a virus
has been caught, in most of the cases, it is dead and useless.  A virus
should infect the greatest area in the shortest time before the anti-virus
people inevitably catch up to the virus.  However, because of the necessity
of a short activation time, this virus has a lesser range than a slow-
spreading virus.  The programmer must rely on either (a) the quick
distribution of the virus along at least a regional level --or-- (b) the
ability of other virus programmers to obtain and modify either the source
code or dissassemble and modify the distributed virus.  If possible, the
source should be distributed along trusted channels.  There should be as
little chance as possible of an antiviral researcher obtaining a copy of
the sourse for your masterpiece.

                        The Case Against Slow
                        +++++++++++++++++++++

        A slow spreading virus is much more likely to get caught by antiviral
people prior to its necessarily long pre-activation period.  There will be
more defenses out against the virus before it has spread much.  However, if
the virus is well-done, it will have spread far before it is caught.

                             Conclusion
                             ++++++++++

        Actually, I lied.  There is no conclusion to be drawn from this, as
this is in itself the conclusion of long hours of thought and much
brainstorming on BBSs.  If you would like to comment, I can be reached on
LandFill BBS, phone number above.  In a future article, I will attempt to
cover anti-anti-virus tactics.  I may also respond to some important
questions/comments I may receive.  Start your viri now!  And may the best
bug win!

           Interview with Skism One - AKA Lord SSS (triple S)

This interview was taken by Hellraiser on July 7, 1991 in Washington
Square Park, Manhatten.

HR:  So what got you started in the virus business?

SSS: Well, I used to write graffiti all over and that got sort of
     played out, so I needed something else distructive to do.  So
     I started getting into computers, then the next thing you know
     I'm writing viruses.

HR:  What was you first experence with viruses?

SSS: Well the first time I heard of them was when that dickhead got
     arrested for putting the worm...

HR:  You mean Morris?

SSS: Yeah that asshole, it was on the news and all that - so I got
     to thinking, that would be a cool thing to do.

HR:  What was the first virus you ran across?

SSS: Ha... Some dick gave me a copy of (pause) it think it was
     Norton 4.0 when it first came out.  So I took it home and put
     it on my hard drive.  The next thing you know all this weird
     shit starts going on.  Like programs won't run and this little
     box opens up on the bottom of my screen all of a sudden.  So I
     get a copy of SCAN, then I find out almost all my files are
     infected with Jerusalem.

HR:  What did you do?

SSS: Well I re-formatted the drive and examined the copy of Jeru for
     months.  Then one day I used a Hex editor to change the suMSDOs
     string to SKISM-1.  Then I went to all the computers I could
     find and infected them.  The next thing you know my friend
     shows me this list with my name on it.  It was Patti Hoffmans
     document.  Shit, I thought I was the man back then.

HR:  Then what?

SSS: Then - well I got into assembler and dissasembly and I started
     to learn how to modify the code and all that.  The next thing
     you know I had made my own virus from the scraps of Jeru.

HR:  Captian Trips, right?

SSS: Yeah, sort of.  Then someone I know sent it to all the boards
     in town under a trojan name and fucked a lot of peoples shit
     up.  Oh well.  Then I guess I grew out of the scavenger mode
     and started writting my own shit, from scratch.

HR:  Like what?

SSS: Well they were all called Skism so and so, like Skism 10, Skism
     11 and all that.  Then I meet people and they started helping
     me out and now we got this thing going on.

HR:  You mean Smart Kids Into Sick Methods?

SSS: Yeah, you know all thid did did dat.

HR:  How do you name your viruses?

SSS: Well depends whats on my mind.  Skism was my tag for like four
     years, so I thought it would be cool if people saw my name in
     the newspaper and all that.  I got Captian Trips after reading
     The Stand, by Stephen King.  1992 was just what I named it cause
     the virus came out to be about 1945 bytes so I jusy padded it out
     to next years date.  808 was named after the TR-808, a 'drum
     machine' used in hip-hop.

HR:  Whats the latest projects?

SSS: You know, you wrote most of the shit.

HR:  Tell them.  The people.

SSS: Well, we did SKISM 1992, which was funny, then a member of
     SKISM, who shall be nameless made 808.  Now I'm just taking a
     break from viruses and computers for the summer.

HR:  You stopped?

SSS: Your crazy, nah - It's got to wait a while, then I'll get back
     into it - when school starts again.

HR:  What do you think of McAffe?

SSS: He's cool, what the fuck am supposed to say.  He does a good
     job at spreading my name around.  I really like Pat Hoffman,
     thanks for the write ups.  You got to understand - these people
     make us into infamous villians.  I can deal with that.

HR:  Do you mind them detecting your viruses?

SSS: Nah, fuck it - If my shit can make it from NY to California
     without effort, it shows it works.  Thats it.  Thers a lot more
     where that came from.  One more thing, I hate that gay bitch
     Ross Greenburg author of Flu-Shot.  What
     a dick.  He's just an asshole tring to sell his shit product.
     He's got a big mouth and instead of crashing his board, I'd
     like to kick his fucken ass.  Where's his office?  Up one 57th
     right?  Lets take a walk.  Just kiddin' but the guys product
     sucks and he's just a greedy asshole.  I'm glad I sent a trojan
     version of his virus scanner around. Ha you dick!

HR:  What virus authors do you look up to?

SSS: Myself - Ha Ha (laughter) Ha Ha.  No, I love Whale - that was
     clever.  I like Dark Avenger, the real one.  Its hard to be
     original, and these guys were.  Hats off you crazy fuckin'
     Bulgarian Metal-Head!

HR:  What about groups of virus writers?

SSS: I think were the only one.  Oh yeah and those Rabid people you
     told me about, yeah there just like us - people tring to make
     there mark in the world, or should I say dent in the world.
     Germans are bugging out too - Shit, they write half the shit out
     there these days.  More power to them

HR:  What is your advise to people who want to write viruses?

SSS: Get a late pass!  No as I said more power to you. Just remember
     you got to have style and learn to be ORIGINAL.

HR:  What next from you?

SSS: I don't really know.  I'm waiting to hook up a few more people
     to the pack, then we'll get the thing rollin HARD.  Till then
     'A little at a time...'


At the time this artical was finished, the Skism team was at work on
a new virus code named Bad Brains.

Part I.  The Dark Avenger
-------------------------

Introduction:

The following text file was sent directly to Professor Vesselin Bontchev in
a public sent to an anti-viral board located in Sofia, Bulgaria.

Bontchev is one of the leading anti-viral researchers in Europe today.  A
producer of number of effective anti-viral programs in Bulgaria, his
programs are widely used throughout Europe.

The Dark Avenger is Bulgaria's most dangerous viral code writer and a heavy
metal fanatic - as this message concerning himself, written by him (often
referring to himself in third person) reveals:

+++++
DARK AVENGER
============

DARK AVENGER is the pseudonym used by a particularly prolific and
malicious Bulgarian virus writer. It is also the name given in the
West to some of his earlier viruses. His viruses include:

DARK AVENGER V651, V1800, V2000 and V2100

NUMBER OF THE BEAST aka 512 (several versions)

ANTHRAX (Infects both files and boot sectors)

V800 and its derivatives: 1226, PROUD, EVIL & PHOENIX

Some other viruses, e.g. NOMENKLATURA & DIAMOND are in his style but
are believed to be the work of others. MURPHY has been strongly
influenced by him but is known to be of different authorship.
CRAZY EDDIE may also be his.

Several 'hacks' are now appearing of V1800, V2100, MURPHY and DIAMOND.

Eddie is the mascot of the British heavy metal group, Iron Maiden
(hence 'up the irons'). It is a 20 foot high skeleton that appears
on stage with them and is featured on the sleeves of all their
albums.

Anthrax and Damage Inc are other heavy metal groups whose names have
been featured in some Dark Avenger viruses. Iron Maiden numbers have
also been mentioned including 'Somewhere in Time', 'Only the Good Die
Young' and 'Number of the Beast'.

Unusually, this virus writer has also produced a virus removal
program together with a version log of his EDDIE series, as
reproduced below with its original spelling and grammar.

"DOCTOR   QUICK!   Virus Doctor for the Eddie Virus   Version 2.01
10-31-89 Copyright (c) 1988-89 Dark Avenger.  All rights reserved.
DOCTOR /? for help

It may be of interest to you to know that Eddie (also known as "Dark
Avenger") is the most widespread virus in Bulgaria for the time
being.  However I have information that Eddie is well known in the
USA, West Germany and USSR too.

I started in writing the virus in early September 1988. In those
times there were no any viruses in Bulgaria, so I decided to write
the first Bulgarian virus.  There were some different Eddie's versions:

VERSION 1.1, 16-DEC-1988

In December I've decided to enhance the virus.  This version could
infect files during their opening.  For that reason, a read buffer
was allocated in high end of memory, rather than using DOS function
48h when needed.  The disk was destroyed instead of the infected files.

VERSION 1.2, 19-DEC-1988

This added a new feature that causes (for example) compiled programs
to be infected at once if the virus is resident.  Also, the "Eddie
lives..." message was added (can you guess why exactly "Eddie"?)

VERSION 1.31, 3-JAN-1989

This became the most common version of Eddie. A code was added to
find the INT 13 rom-vector on many popular XT's and AT's.  Also,
other messages were added so its length would be exactly 1800 bytes.
There was a subsequent, 1.32 version (19-JAN-1989), which added
self-checksum and other interesting features that was abandoned
because it was extremely buggy.

In early March 1989 version 1.31 was called into existence and
started to live its own life to all engineers' and other suckers'
terror.  And, the last

VERSION 1.4, 17-OCT-1989

This was a bugfix for version 1.31, and added some interesting new
features.  Support has been added for DOS 2.x and DOS 4.x.  For
further information about this (the most terrible) version, and to
learn how to find out a program author by its code, or why
virus-writers are still not dead, contact Mr. Vesselin Bontchev (All
Rights Reserved).

So, never say die!  Eddie lives on and on and on...  Up the irons!"

NOTE:
Vesselin Bontchev, who the Dark Avenger is trying to discredit, is a
leading virus researcher at the Bulgarian Academy of Sciences.

Post Note:

There is a rumor concerning the fact that RABID now has the Dark Avenger on
their staff of virus writers, and that the new Dark Avenger variant released
by them was, in fact, written by him.  This has yet to be proven.

The more acceptable belief concerning this new strain is that RABID simply
picked up the source code for Dark Avenger, released last December, and
modified it.

Part II - Dark Avenger - Strain A
---------------------------------

Vesselin Bontchev reports in May 1990:

The Dark Avenger virus.
======================

- I found two new mutations of this virus. Well, maybe
  "mutations" is not the correct word. In the first of them, the
  first 16 characters of the string "Eddie lives...  somewhere in
  time!" were replaced with blanks.

In the second example, all strings (the message above, the
copyright message and the "Diana P."  string) were replaced with
blanks.  - The author of the Dark Avenger virus (The bastard!  I
still cannot determine who he is.) has released the source code
of his virus.

It is full with ironic comments about me.  Of course, now we have
to expect lots of new, similar viruses to appear.  At least, this
leaded to one good thing - the source helped me very much in
disassembling the V2000 virus.  - I received a rather offensive
anonymous letter from this person.  In it he claims to be also
the author of both the V2000 (I trust this) and the Number of the
Beast viruses (the latter is unlikely).  [See Above]

Note:

This information is far more valuable than the standard
Virus Summary by Patricia Hoffman.  Her entry concerning DA
fails to go into more depth about the Dark Avenger virus and
apparently she has yet to receive information of the
different versions of DA.  Such information is already a year
old, but she has yet to include it.
