<ST>Hey, what happened to connecting my system to the file echo?
<ST>
<ST>I have sent numerous netmail messages to you since you sent the info
<ST>on setting it up and have not had a reply yet.
Recheck your netmail, I sent a reply after receiving the message "What is
Tick?" indicating that you need to be running Tick in order to be able to
participate in the file echo since that is how the files are processed and
extra files go with the .zip files that carry the description. Tick is
available from most SDS nodes.

Jim... this is a little mis-leading... all programs will become infected
but FSHLD will remove it for most viruses.. for viruses like 4096, FSHLD
won't remove or even know/announce that the file is infected...
When FSHLD can remove a virus, 'after execution but before running'
really makes no difference since a resident virus will still go TSR and
a direct action virus will still do it's infecting of other programs...
But all things considered... I definately agree that FSHLD is a must
have...

Subj: RE: KEYBOARD REMAPPING....
yes, it is possible to re-map the keyboard from a remote system. However, most
people are protected by this because the term program rather than ANSI.SYS is
handling the ANSI escape sequences.
If you are using a "dumb" terminal that has no terminal emulation and allowing
ANSI.SYS to handle your screen formatting, you may be in trouble.

QUOTE ON
I've been informed by "reliable sources" that there's a file floating around
called 486COMP.* (select your favourite packing method) which claims to "show
you the difference between your machine and a 486".
.
When run, the program flashes a "too big for memory" message, and aborts.
.
Then, the next time you boot, you're informed that you have the "Leprosy 1.00"
virus which then hangs the machine.
.
After you manage to boot from a floppy, you find that COMMAND.COM has been
altered, although the date, time, and size appear not to have been changed.
Just thought you'd like to know.

I can't help but wonder if Herb was experiencing something that suggested that
kind of remapping. Lately I have been experiencing keyboard problems that seem
to act like that. When I use my down or left arrow the \ and | symbols toggle.
I can correct this when it happens by hitting the left hand shift key - but not
the right. And tonight it seems as if I am occaissionaly transposing caps on
and off.
If either of you hears a virus like this I'd like to know. Q&A tested my
memory and keyboard fine. Scanv66 detected nothing.

Subj: REMAPPING...
Hello, Tom...
.
More than likely there was nothing like that at all. Keyboard
remapping is an extremely complicated process and would take more than
forethought on the part of the programmer. What you have seen us
talking about here is figurative at best and personally, I would have
to see it to believe it. (you know the old saying: "Believe none of
what you hear and only half of of what you see."?) Although I do
believe that is quite possible under the proper circumstances, it would
indeed be a rare occurance. Sometimes when receiving odd characters
during telecommunications or not getting the exact same keys that you
typed could be attributed to disparity (parity differences), differing
data bits, stop bits, or even simply ANSI interpretation problems
between Comm Programs. I've seen the smallest, simplest things like
that have people pulling their hair out by the roots!

I took a look at it, but to be realistic, when you run a BBS, or are
continuously updating your files as new releases come out, you could easily get
to the point where you spend more time reconfiguring the anti-virus program
than you would getting any work done. I find it much more efficient to scan
every file for viruses as soon as I get it on my system, then rezip it, if I'm
not going to use it... a simple .bat file can be used such that if you want to
check multiple files, you can just feed the file names on the command line and
let the .bat file take care of unzipping, scanning and rezipping the file.
Be best if someone would write a program that would do this, but I haven't
found one yet.

Subj: VIRUS RESCUE & F-PROT RELEASES
The latest version of Fridrik Skulason's F-PROT anti-viral program is now
available for download from my system as FPROT112.ZIP. The program can also be
file requested as F-PROT, which will always return the latest copy I have
available. This program is actually a "suite" of programs for use in
preventing and detecting viruses and trojans. The program originates in
Iceland, and so updates to it reaching my system for distribution have been
rather sporatic.
The other new anti-viral program available on my system is Virus Rescue. Virus
Rescue is from Tacoma Software, and is a shell for invoking ViruScan, CleanUp,
and VCopy from McAfee Associates. Unlike other shell programs I've seen, this
one should not require updates every time a new release of Scan comes out. It
picks up its virus information from the VIRLIST.TXT file which is packaged with
Scan and CleanUp. It will be handy for those who have trouble with the Scan
and CleanUp command line switches, or who want the VIRLIST.TXT information
converted to english sentences. This is a first public release, so I expect we
may see some changes in this product in the future. Virus Rescue can be
downloaded from my system as RESQ01.ZIP.
Both programs are also file requestable by other systems. File requests should
ask for magic file names as follows:
F-PROT for the latest copy of F-PROT (currently FPROT112.ZIP)
RESCUE for the latest version of Virus Rescue

sounds like a plan to me. it would actually be fairly simple to write a
program to look at all the files in your upload directory, unpack them based
on the extension, scan them, then re-compress them (if needed). of course
you'd still have to manually put the now scanned files into the proper
catagory directories yourself. when do you need it and what's it worth? :-)

(All answers gratefully received despite the TO: line)
Anybody heard of this? I've got a floppy with some viruses on it,
among them a SCAN-known Dark Avenger. I SCAN this floppy from the C
drive, and the "hey, nothing to worry about there" report comes back.
Strange. I SCAN it again. This time 'round, SCAN barfs after 64K of
the memory check, telling me Dark Avenger is in memory, power down,
load the .45, get the cyanide tablet ready and so on.
But DA of course is NOT in memory or active in any way. It is,
however, on the floppy, unrun.
The above occurred with SCANV64. Out of curiosity, I cranked up
SCAN-54 and -- EXACTLY the same result.
AST Bravo 286, no TSRs, nothing else loaded, clean (normal) boot
just performed.
I have a bunch of viruses that I don't expect SCAN to find --
ever. But this kind of thing has never happened to me before. Can
anyone match this story, or event?

PL> a message about a TAG Sysop who contracted that virus. Any Info?
PL> Supposedly the Virus is scanned in version SCANV66.ZIP.
Yep, I've heard of this one....I was the one that named it after it was
submitted by Mike Shields (Sysop of 1:244/114). Ontario is a memory resident
generic infector of .COM and .EXE files, including COMMAND.COM. Infected .COM
files will increase in length by 512 bytes. Infected .EXE files will increase
in length between 512 bytes and 1023 bytes on disk drives with standard 512
byte sectors. When files are infected, the virus adds itself to the end of the
program, and then places a jump at the beginning so that the virus's code will
always execute before the program that was infected. Ontario is not a
low-system memory TSR, it goes memory resident installing itself at the top of
free memory, but below the 640K line. Available free memory will decrease by
2,048 bytes. Once the virus has installed itself in memory, any program which
is executed will then become infected.
It was reported with the sample I received from Mike that infected systems may
experience hard disk errors, but I was unable to duplicate that here. This may
only happen in severe infections, I try not to let them get that severe when
I'm working with a virus :-).
Scan V66 and above can detect the Ontario Virus on both .COM and .EXE files.
Unfortunately, Ontario is one of the viruses that uses a "double-encryption"
technique to prevent scanners from being able to use a search string to detect
it, so there isn't a simple way to find it with a hex string and a utility such
as Norton Utilities. As of right now, there aren't any disinfectors available
for the Ontario virus, so if you happen to be infected with it you need to
remove the infected programs and replace them with clean copies from your
uninfected backups or original write-protected distribution diskettes.
A more complete description of the Ontario virus is in VSUM9008, which was
released on August 10. The above is just off of the top of my head, which
happens to hurt right now. Hope it is understandable.....

You might want to take a look at CheckOut and Shez.
CheckOut uses ViruScan to check .ARC, .PAK, .ZIP, .LZH, and other archive
formats for viruses by automatically creating a temporary directory and
unarchiving the file to it. It then invokes Scan to check the executable
files. One of its nice features is that it will never invoke a program in that
temporary directory, as well as you can have it either delete an infected file
or move it to a badfiles directory. It will also find archives which are
damaged for you. It can be invoked easily from a .BAT file, such as if you
want to run it at midnight against all new uploads.
Shez is another program which can be used to scan inside archives. It is
interactive, so you need to manually invoke it. After you have selected the
archive and listed the contents, hitting ctrl-Z will result in Scan checking
the contents.
There are other scanning shells which handle archived files, though these are
the two that I've used regularly and are the most familiar with. I was also
involved in the beta testing of CheckOut with some known to be infected files,
and it does function properly in that instance. I've also tested Shez with
infected files, and it works well....

PH> The Vacsina Viruses were written in Bulgaria to seek out and destroy
PH> certain other viruses, or at least that was their original purpose.
In examples of the VACSINA virus I have investigated, I have found the
following odd behavior, which I wonder if you have also noted :
.COM files of over a certain size are infected at first bite, but .EXE
files are different. It takes two Exposures to infect an .EXE file, each of
which adds a bit to the file length, but only at the second exposure do you get
a live virus, signaled by a short beep. A tiny .EXE will take the first
exposure, but never complete on a subsequent exposure to become a live virus.
I wonder if in some way this behavior, which I have not seen in any other
viruses so far, is in some way related to the original "anti-virus" nature of
this beast ?

could you send me this article? i still believe that the virus would have to
know your crc algorithm in order to perform this magic. additionally if the
file is padded, it's size would increase and would be detected that way.
correct? sooo, the person writting the virus would require a copy of your
file to disassemble, see how you performed your checks, then create a means
to circumvent it. sounds like a lot of trouble to me for very little gain.

Subj: VIRUS_INFO INTRODUCTION & RULES
Welcome to the VIRUS_INFO echo. The purpose of this echo is to allow
BBS users and sysops to ask questions about computer viruses and to be
able to get back up-to-date information. Discussion topics may include,
but is not necessarily limited to:
- what are viruses
- how to prevent getting infected
- how to determine if your system is infected
- how to clean up an infected system and salvage as much information
as possible
- reviews and announcements of new anti-viral products and product
releases.
There was a lot of hysteria in the press over the Columbus Day/
DataCrime/October 12 virus, for example, but little mentioned of how
rare the virus is or how to determine if a system is infected with it
and how to remove it. This type of information is an example of what
this echo is intended to carry.
Some messages appearing in this conference may be cross-postings from
the Dirty_Dozen echo which is sysop only. Cross-postings may only be
done by the originator of the message. For example, several of my
messages posted in the Dirty_Dozen echo will be cross-posted here.
Messages from the HomeBase/CVIA BBS run by Mr. John McAfee in Santa
Clara, CA and/or CVIA bulletins may be posted here by Patricia Hoffman,
these are being done with Mr. McAfee's permission. Replies to these
messages, as well as netmail received at 1:204/869 for Mr. McAfee, is
manually transferred to his system as it is received.
Conference rules are very simple.....
1. Discussions of how to write a virus, specific technical discussions
of how a virus works, or anything of an illegal nature, are not
allowed. This rule is *not* open to debate.
2. Messages with a sexually suggestive nature are not allowed, please keep
in mind that minors as well as adults participate in this conference.
3. Discussions of a ethical or retorical nature that lead into a debate are
considered off-topic in that they will not ever be resolved and do not
help anyone. An example in this category would be a discussion in the
area of "Should live viruses or virus disassemblies be made available
to the public?". These questions and topics will be allowed until such
a point that they start to severely disrupt the echo, or start a flame
war. At that point, the moderator will request that the discussion be
discontinued.
4. Be courteous to your fellow echo participants, and remember there
is no such thing as a dumb question, except for the question that some-
one is afraid to ask. Everyone needs to help everyone else understand
viruses and why they are a problem.
5. This conference is not to be distributed thru Group-mail or any
other mail processor which will obscure the ability to track a
message back to an originating system. All messages must have
seen-bys and path statements if the BBSs participatings software
can generate them.
6. If you have a question or problem of an extremely sensitive nature,
consider sending it NetMail to 1:204/869 or 99:9403/2 instead of
posting it here. If you are netmailing a file that you think is
infected, be sure to send a message in NetMail with it so I know
what it is, I'll be sure it gets to someone to get analysed for you.
Do not under any circumstances host route a file that you think is
infected. Suspect files may also be sent on diskette via US Mail
to the following address:
Patricia Hoffman
1556 Halford Avenue #127
Santa Clara, CA 95051
7. This conference is available to FidoNet and EggNet systems.
The conference echomail tag in FidoNet is VIRUS_INFO, in EggNet
the conference is available as E_VIRUS_INFO.
8. This conference is available on the FidoNet Backbone. While you
are welcome to freely pass this echo along to other systems, out
of region links must be approved by moderator of the echo. Gating
the echo into another network or Zone must be approved by the
conference moderator.
9. Opinions are welcome in the conference, however the ethics of the
behavior of people that write viruses, or name calling, is frowned
upon. Likewise, accusations of virus writing are strictly forbidden.
Please keep opinions down to a single message, and do not
repeatedly post them, as these messages tend to water down the
purpose of the conference and degrade the level of information that
is being presented.
10. Handling of off-topic messages or messages that violate the
conference rules will be done by the moderator. First and second
warnings on these messages will be in private Netmail. Please
do not respond to the off-topic messages so that the conference
doesn't get further off-track. Let the moderator do the moderating.
11. Handles are allowed in this conference, however sysops of boards
carrying the conference are expected to be able to determine which
of their users entered a message if a problem arises. This in
effect means, for example, that Opus systems must not set this echo
up to allow anonymous messages.
12. If a matter arises where the moderator needs to contact a participant
in the echo, the moderator will contact the system where the message
was entered and request that the sysop allow the user netmail access,
or call the participant with a request for them to logon to the
moderator's system or provide a phone number with the participant's
permission. Sysops are not expected to provide their users' phone
numbers to the moderator without the user's express permission, their
privacy is important. There are times, however, when a phone call
or chat can resolve a problem much faster than any other route. This is
the only reason for this rule.
12. This echo is not a programming echo for answering questions
on how to code programs in assembler. If you want to exchange
assembler (or any other program language) techniques, please
locate an appropriate programming echo or start your own echo.
Patricia M. Hoffman is the moderator of the VIRUS_INFO echo conference. She
has previously used the name "Merry Hughes" in moderating this conference, and
is the originator of the conference and the original moderator.
Patricia Hoffman is also the author of the Virus Information Summary List, and
is an independent anti-viral researcher.
Please contact the moderator, Patricia Hoffman, at 1:204/869 or 99:9403/2
if you need assistance on setting up an echofeed for this echo to your
system.
thanks...

The Leprosy virus is a non-resident overwriting virus. It infects .COM and
.EXE files, overwriting the first 666 bytes of the file. Symptoms of it
include that infected files will not execute properly...instead of what they
are supposed to do, they will upon execution, infect other files then display a
message and end. A complete description of this virus and all (with the
exception of V2P2, V2P6, V2P6 and Stoned II) known MS-DOS viruses as of August
10, 1990 is available in the Virus Information Summary List. Its current
version is VSUM9008.ZIP. It is available on my system at 408-244-0813, as well
as many other systems, including McAfee's BBS. Check around your area before

Subj: REPLY TO MSG# 2753 (Re: VIRUS ORIGINALS)
Firstly, I did not wish to anger you (although I seem to have done just this),
but only sought to answer your question to the best of my abilities (which you
seem to doubt).
Secondly, I stand by my original assertions that viruses were developed through
the original Core Wars gaming system. This has been corroborated by various
'virus gurus' here at the local university. In fact, without prompting, one
mentioned Bell Labs. Since, as you state, you are a Systems Programmer - it
should be obvious to yourself that a RedCode program could be easily adapted to
the microcomputer world. It should also be equally as obvious that these
RedCode experiments have laid the groundwork for many of the various virus
types infecting micros today (ie. trojans, worms, etc.).
Thirdly, I did not state, nor did I mean to imply (as you seem to believe),
that these RedCode 'fighter programs' are in fact the viruses we see today -
merely that they (RedCode fighters) provided the techniques for the micro
viruses. Furthermore, since the RedCode experiments were "old system
programmers games designed to give Egoistical programmers some lighthearted
fun", and since it is generally accepted that virus writers are in this for the
same reasons (the egotistical, not the fun), I find it hard to beleive that you
cannot equate the two.
If you will note in the extract below, I am not the only person who who
beleives the RedCode experiments were the forerunners of the modern viruses (in
fact, it may be noted they refer to these as viruses - which, of course, they
were);
From the Sept./89 issue of Popular Science;
Despite all the recent publicity, viruses aren't new. In the 1950's researchers
studied programs the called "self-altering automata," says Mike Holm...
In the 1960s computer scientists at Bell Laboratories had viruses battling each
other in a game called Core Wars. The object was to create a virus small enough
to destroy other viruses without being caught....
Also, just for the record, allow me to mention that this is an American
publication (apparently there are strange drugs down there too).
Again, for the record, allow me to mention that it is fact that Robert Morris,
Sr. was a participant in the Core Wars games. Is it a coincidence that his son
wrote the Internet Virus, or did his father give him the building blocks to
build upon? (With my apologies to the Morris family, but I felt this example
might carry some weight with Know-it-all System Programmers).
To answer your original question, in a form that you may deem acceptable (ie.
no RedCode, no mainframe systems, the US is not the origin - all those naive
things), the original micro virus was (at least in the IBM world, I can not be
sure this applies to early Apple ][ systems, or even the Pets from Commodore)
the "Pakistani Brain", released in Jan. '86.
But it must be noted (although I feel you will reject this also (ie. mainframe,
US, etc)), in Nov. '83, Fred Cohen, in 8 hours wrote a virus which attached
itself to users programs, and proceeded to use this program to gain access to
all system rights (in an average time of 30 mins). Also, although I don't have
a date (the computer name itself may give some indication of age) - on a UNIVAC
1108, with a secure operating system using the Bell-Lapadula model for OS
security, a virus was created that: infected the system in 26 hours, used only
legitimate activity with the Bell-Lapadula rules, and the infection took only
250 (approx.) of code (From "Computer Security: Are Viruses the AIDS of the
Computing Industry?", by Prof. Wayne Patterson, Chairman, Dept. of Computer
Science, University of New Orleans.).
I am not interested in a war of words, so I will suggest some reading before
you go off half cocked to this reply - "Computer Security; A Global Challenge,"
J.W. Finch & E.G. Douglas, eds., Elsevier Science Publishers, North-Holland -
especially the chapters by Fred Cohen. I have not read this, but will try to
when it becomes available to me. Also see the message posted by Phillip Laird.

There are a couple of possibilities here. First, if the virus is on a
non-executable file, such as one with a .VOM or .VXE extension, Scan won't find
it since it is not one of the file extensions it checks for Dark Avenger. In
this case, a subsequent run of Scan may find it in memory anyways since the DOS
buffers in memory are not cleaned out between program executions. If this is
the case, running Scan with the /A option will find it on any file, regardless
of extension.
Likewise, if your copy of Dark Avenger has ever had a disinfector run against
it, it may have some "dead" Dark Avenger code after the end of file mark, but
within the last sector of the program as allocated on disk. In this case, Scan
won't find it on disk, but may later find it in memory since the code after the
end of file mark was read in with the rest of the last sector of the program to
memory. This is what is sometimes referred to as a "ghost virus", it isn't
really the virus, just dead remnant code remaining in the slack space in the
sector. It can't be executed. Running a disk optimization utility such as
Speed Disk from Norton Utilities will get rid of the "ghost virus". They are
caused by the way DOS fills out the end of the buffer before it writes it out
to disk, doesn't always occur when disinfecting programs, but it sometimes will
occur.
The other case is if your copy of Dark Avenger does not occur at the correct
place in the file. Dark Avenger always adds its code to the End Of Programs.
If your copy happens to have it at the beginning of the program, or perhaps
imbedded in the middle where it shouldn't be, it may not get found. In this
case, your copy doesn't match either of the Dark Avenger's that McAfee has.
Hope that helps....those are the only three cases that I've heard of a similar
problem to yours.

I had heard that and infected version of LHARC was released last year under the

was expected to be LHARC200 to avoid confustion with the virus. This week a
file appeared on a local board called LHARC114. I left a message to the sysop
to check it out and he says it's clean. The docs say that this is version
114b, the latest version.
Does anybody know what the deal is or was here? Is LHARC114 safe to use? Is
there a virus associated with this program? Thanks.

Hi there, you guys must be behind the times or something but there is a very
good program which does exactly what you are looking for. Its called CHECKOUT.
The version we are using over here is called CKOT11.ZIP and it is a little
pearler!!
What it does is, unzips a file, scans it and rezips it, menu driven or
command line driven. Try it, you'll love it.

The following item appeared in a newspaper in Brisbane, Austsralia yesterday.
Anyone care to comment?
VIRUS ATTACKS STATE'S PERSONAL COMPUTERS
A sophisticated computer virus is feared to have infected Queensland Government
and home computers. The COMPUTER VIRUS INFORMATION GROUP at the QUEENSLAND
UNIVERSITY OF TECHNOLOGY has issued it first major warning to personal computer
users about the virus.
The virus, initially detected by the Israeli defence force, freezes computers
on September 22, the birthday of a character in Tolkien's book, 'Lord of the
Rings'.
A computer virus is a program designed to attach copies of itself to software
and disable a computer system, or destroy files. Acting technologist, MR
EMLYN CREEVY said the warning was issued after a State Government public
servant gave the virus to the group for investigation.
Mr Creevy said somputers infected with the virus - known as FRODO, 4096, or
CENTURY - would freeze on September 22 or until the end of the year unless it
was removed. He said the group expected to know if the virus had infected
computers in Queensland next week after users report the results of searches
they were requested to conduct. The group warned all personal computer
operators that there was a bug in the FRODO virus which prevented it from
displaying a message 'FRODO LIVES' on September 22 and instead caused the
computer to 'hang' or freeze.
"It is from the FRODO name that the significance of the 22nd September can be
identified," they said. "This is the birthday of Frodo Baggins in Tolkien's
story. Users are advised to theck for the virus as soon as possible.
Mr Creevy said the virus had the ability to avoid detection and spread but was
not 'seriously destructive'. He said it could become damaging if an expert
could disassemble the virus and change the instructions to wipe the computer's
disk. "I'd say there's people working on it somewhere although probably not
in Australia," Mr Creevy said.
An expert would have created the Frodo virus because it had only one bug while
most viruses had more.
Mr Creevy said more than 100 viruses were believed to exist worldwide.

sandyp.s. these attacks have been common since programmable
terminals came into being during the middle 1970's the problem is that
when these features were implemented in comm programs the possibility
arose that it was possible for malicious individuals to finally do some
real damage...the way to protect yourself is to STOP using programs
that implement such features and switch to others that are more secure
in their usage of such features...

Ontario loads into the top of free memory, right below the 640K boundary. It

to back-up the FAT).....But, almost all of these that I have seen
pertain to the HDU! I realize that there are ways to write it to a file

This just hit me today - I am not sure if it is some kind of system error or a

Last night (September first) and before gave me no indication of any virus
being present on my system. It is now september 1st and now, whenever a file is
written to disk (I noticed the text files first, but a downloaded zip'd file
was also garbled...) it took out about 10 bytes from the beginning of each
line...
When I realized this may be set to occur on this date, I set my DATE back a
night and everything worked fine... I made a sample text file with a known
pattern of characters -- any date past september 1st 1990 leaves the file
altered as mentioned above. Any date previous is written unharmed...
SCANV56 reports only that the SCAN program is damaged - no disk presence of the
source is evident.
Has anyone heard of something like this happening?

I have a copy of the Leprosy virus along with its source and
"documentation". What it does is copies itself to 4 exe or com files
each time it is run and produces a memory error code so the user thinks
there is a problem with memory and runs it again. After all the com and
exe files have been infected, it displays a message that they have a
virus and "Good luck!"... It increases file sizes by 666 but when I
tested it on a floppy, the bytes didn't increase...

I am a Private contractor for a Large Network installation an support company.
I work for the good of the Customer and the population (users).
I hear the phrase " SLIMY CONTRACTOR" " M.F.C." everyday. I also heard
"Can this be done", "Would you look into this...", "What are your suggestions
so I can put them in my report" when things get deep. We are the WHIPPING BOYS
and EMERGENCY 911 all in one.
I am sure there are Software contractors who have planted or released a virus
at contract renewal time. To show how much they are needed.
There are also those of us the that want to see their job sites safe from such
problems. We are the ones who own our time (Non-Paid) Compile information
on ways to safe guard our data from compermise or viral attacks.
The Anti-Viral reseach done by Mrs. Hoffman (PAT) and John McAfees group
is carefully read and evaluated on my end. I am sure it has saved many a rear

Subj: SECURING YOUR UPLOADS
I've got checkout, and while its a pretty neat program, there are a few
things I don't like about it, the main one being the initial memory scan. I
also don't like the auto-pause that seems to be at the beginning of it. That
means running gateway, which means the user may be able to get into DOS and
party. (have heard of Key-fake, but never seen it around to play with it..).
TAG calls a file named postul.bat after every upload (if the .bat file is
present), so I hacked up this .bat file to auto-check for virii. But I'm not
smart enough to know how to use the %%f in a batch file to have it run through
for all the files in the active directory (for batch uploads)...
Maybe there's a genius out there who can help. FYI the parameters passed to
the .bat file are: [Baud] [ComPort] [User#] [U/L Dir] [Filename].
Here it is. Chuckle, then help make it better <grin>.

Also, I have a program that will make a .com fil out of a .bat file, for faster

about after the %%f is added?

I have a copy, and think it came out around March, or so. At the time,
SCANV detected no virus, but I thought better of running it.
Sorry, folks. Whatever it is, it isn't available for downloading, so please

You are correct.....What the CRC/Checksum interrogator sees, if 4096 is in

actually out on disk. Fish 6 also does this, as do a couple of other viruses
using Stealth techniques.

Lots of 4096 infected files will run without hanging the system....the virus
disinfects the program when it is read into memory so that anti-viral packages
can't find the virus as easily. CRC checkers and scanners won't be able to
find it in the infected file if the virus is in memory, in fact, these viruses
usually infect on file open as well as execute. Run a CRC checker or Scanner
that doesn't check memory for the virus with it present and you'll infect
everything that is openned that meets its infection criteria.
If the virus isn't in memory, the CRC checker technique will work to identify
the infected files in 99% of the cases. I'm not going to say 100% because I
believe some of the 512 virus variants can get around it due to the way it
attaches to the files in some cases, but not all. Some CRC checkers don't
actually CRC the entire file either....and as soon as I state it is a fool
proof way of doing it, someone will write a virus that gets around it
perfectly in all cases.

I seem to be missing something here. As I understand it, to check for virii
with a scanner, such as SCAN, or whatever, you boot from a uninfected floppy
that has scan residing on it. Ok, now, how would a virus that works as a TSR,
that probably is loaded from the boot sector from the hard disk be loaded, if
you are booting from the floppy? Which, the floppy being write protected, of
course, would not have this viral infection. I was under the assumption that
the BIOS first checked drive A: at bootup for a disk, etc. It seems that it
would be impossible to find a virii in memory with this type of scheme.. Please
enlighten me..

Hear, hear! The frustrating, rug-chewing, desk-beating,

viruses, on a technical level, are tremendously slick, wonderous
programs. The people writing them are wonderful programmers. Just

Sure. Something ELSE has infected it. No reason not to let it run so
long as it still works. One of our local youngsters wrote a wonderful
remover of the Dark Avenger -- about 1400 bytes and worked like a
charm. Only one teensy-weensy trouble -- the remover got infected and
didn't warn you. That's not really one of the more useful programs to
have around.
Since it seems to be the constant topic of conversation here,
SCANV's routine of warning of infection and continuing its duties is
great.
A common cause of re-infection is forgetting to remove the tools
you used in the disinfection process -- stuff like LIST, just for
example, that you might have used to examine the virus.

No, in a metaphor placed in 1970 terms, we get to the airport two
hours before flight time for the security checks. And for the same
reason, too -- the unwillingness of the many to take the resolve to
remove the few. We have, most of us, helped the virus writers build
up their existing sick belief that we are willing participants in
some kind of game here. They win if they manage to steal our time,
programs, disk space and data. They only do it because they had an
unhappy childhood, right?
One tangible result of allowing them to feed on this warped view
is this echo, where we're all trying to get to the airport two hours
early for the security check -- AND WE'RE ALL WASTING TWO HOURS
because somebody we don't know might try to hurt us.
We should have sympathy for Robert Morris, of course, because
after all, he was just experimenting and not REALLY trying to hurt
anyone, right? I have a one-word, two-syllable response to that but
FidoNet policy frowns down upon me for thinking of using it.

This is just a thought, too. But why not take your clients into your

anyone to match the up-to-dateness of a BBS distribution system?
You're a BBSer. You know, just for example, that without BBSes McAfee
couldn't have a program-of-the-week. Distribution of what your
clients think of as commercial software simply isn't up to this
standard -- isn't meant to be; never was; probably never will be.

explain to them why they should be using SCANV. Why reinvent the

Roger that. A program (such as a virus) can possibly figure out a
checksum or CRC and "fool" your checker. But complex and random
checksumming or CRCing is beyond the real-world possibility of defeat
by a PC virus -- it would have to be too big and complex itself.
Our strategy on our anti-virus program is to have eight different
algorithms, and to use two of them on each checksum pass. Which two,
even we do not know. Your virus then would have to take into account
64 reasonably complex algorithmic possibilities to defeat it.
Patti is technically correct that this can be done -- but not in
the real world. I'd tend to be slightly suspicious if my word
processor suddenly grew by the size of THIS virus. Most programs
would, in fact, be incapable of loading it.
As you say -- make it complex (which isn't so difficult) and keep
churning out hundreds of different algorithms. Then you can forget
about "stealth" viruses succeeding.

This is absolutely correct, of course, and EXACTLY what's recommended

I do do some experimenting with viruses and anti-virus stuff, because
Bangkok's a "virus capital" (dumb dealers plus a whole raft of
pirates) and because I'm involved in a commercial anti-virus project.
This was just a weird thing that happened to me when I was "playing"
with Dark Avenger. I do wonder how many people follow that
"write-protected floppy" recommendation (order???) in the SCAN docs,
though.
One note on your comment: it might be hard for some people to
follow the recommendation, i.e. those with one floppy. The total
beauty of SCAN, really, is to look over that new stuff. A lot of
machines go to new people with one floppy drive.
A lot also go with two different floppy drives (my own setup)
although this of course is combatted simply by having TWO
write-protected diskettes with SCAN aboard.

the company name almost slipped out there, thought this was
hilarious, left it in and shipped the thing. I'll send full details

This same company, the next time it shipped viruses, claimed that
a guy in the shipping department was playing a game and accidentally
infected the shipment (exclaimer!!!!). Is this a company with a weird

Setting the "Read-only" attribute wouldn't even *phase* a decent virus, and
SCAN's internal checksum is VERY weak. (It quite literally is a checksum.
It simply checks to see if all the words in the files add up to 0.)

HB> enlighten me..
The memory resident viruses that are a real problem when they are in memory and
any antiviral, whether a scanner or CRC checker, is run are not boot sector
infectors....4096, Fish-6, Dark Avenger, and many others which infect on file
open are file infectors. There are three that are file infectors but can also
infect and replicate from the partition table and/or boot sector: V2100,
Anthrax, and Plastique 5.21. (These last three are extremely rare, fairly new,
and not known in the United States.) All of the viruses mentioned about use
"Stealth" techniques to avoid detection or infect on file open.
If you are booting from an uninfected diskette when powering on the computer,
you wouldn't ever find a virus in memory. However, if you are performing a
warm reboot from a floppy, you could have a virus in memory still. The real
point here was that most people do not run scan or other anti-viral utilities
after powering on and booting from a floppy, so it is always possible for the
virus to be in memory.
In that particular case, for a CRC checker which is what was being discussed,
there are definite cases (the "Stealth" viruses) where the virus can get around
the CRC checker simply because if the virus is in memory it disinfects the
infected programs as they are read into memory. The CRC checker, since it is
performing file reads, reads the DOS buffers to check the program, so the
program it sees isn't infected and isn't the same as what is actually on the
disk. In the case of viruses that infect on file open, running an anti-viral
product against all the programs on a system with the virus active in memory
can very well result in all the programs becoming infected.
I'm not against CRC checkers, I use one all the time on several of my systems.
These systems all have master boot diskettes with clean system files, the CRC
checker, and the log of all the expected crc values to be returned. Most
people simply do not have that type of diskette setup for their systems since
they feel they'll never be infected with a virus. In fact, the probability
that a person will be infected with a virus is fairly low, though it does
change depending on the person's computing habits and how often they exchange
diskettes and/or programs with others.
I was trying to point out that NONE of the current anti-virals will absolutely
protect a user from getting a virus....all the techniques currently used by
anti-viral products can be circumvented by some of the newer, more
technologically advanced viruses. Not to point that out would be like burying
one's head in the sand, especially when the discussion has to do with someone
thinkin of writing a new anti-viral who needs to know what can currently be
circumvented. It is easier to fix the design before the program is written
then to fix it later after the hole is found....

I totally agree that most people do not read the docs. I work for a University
in South East Texas. Some of the Micros have been plagued with viruses. I
have setup a routine for the Labs to Scan the Floppies coming in with SCAN.
This has just taken Place. Next thing I know, the clerk decides to run SCAN
From her hard drive on her desktop! Then Alameda hit her! The SCAN Program
has gone over good at the University. We are getting an order ready for a Site
License Agreement with MCafee and Associates. I do a little research on some
of the strains. However this BBS keeps me busy after work!
Weird thing about CLEAN.EXE the program to remove the Viruses. I am using
Clean Version 66 and sometimes the program will scan the file numerous times
before the virus is eventually removed. I guess the Marker is trying to move
around in the file? Anybody know?

something new.

According to want I've read Dr. Fred Cohen at MIT developed the first virus

that in the first place?

have anything to worry about if it's already infected when you get it. (Except

Well, first of all you've got an old version of scan. Try downloading scanv66b
from someone. I have it if you can't locate it elsewhere. Second if scan ever
reports being damaged there's a 99% chance that you've got a virus! Better
check into it quick! Hope you don't find that you have one but it sure sounds

Could I ask wy the buffers would be causing the Boot Block to be altered.
I have since removed the val checks using ScanV66B and put some new ones on
using ScanV66B.
Could it be possible that someone has altered a bit of the code and as ScanV66
uses a string (or is it hex search) it doesn't find it?
eg In the Virus it originaly said "Your disk is stoned' and the person
converted it to say 'Your disk is now stoned'. If ScanV66 happens to look for
the original string to my knowlegde the virus would not be recognized.

THat is exactly the way I have found some of the Virii I researched as being.
If the virus is present in memory, then it is possible the the file will
infect, however, if the Scan Diskette is write protected and the diskette is
bootable, Like oyu say. It is BEST to cut the power to the system and then
re-boot the system. However, if you wanted to go a step further, it is
possible to clear all volatile RAM if you want to do a warm boot. The Warm
Boot can result in infection, since the ram is not cleared. The various
hardware interrupts are still performed and cotrol passed to Command.com, but
the System files are still present in memory, along with a virus possibly. Too
many people are now taking the virus issue too lightly. It can effect you,
take precaution and use the Floppy to boot up on with a Write Protect on the
Diskette. Then scan the drive from there.

That is exactly what I had suspected. I assumed the file was re-infected
several times as the size of the Original WP.EXE files that were infected once
was for example 112K, and the ones that were infected several times was around
173K. Some of the programs were non functional after clean ws performed on the
file. We just delte the file and re-copy it when that happens. The only safe
way to do it I have found is to go ahead anuse scans' /D option and delete the
file and re-copy it.

Well you can Download a Virus scanner from a reputable BBS -- one that

Virus Scanner. Most of the downloadable stuffis by Mcaffe Associates, You can
purchase Virucide (commercial version) which checks and disinfects your files,
also by Mcaffe Associates for about $30.00. Not a bad buy when you consider the
consequences of not having a good scanner.
Just make sure that after Downloading a file, unarc-unzip-unwhatever it, But
under no circumstance activate it --- run it --. Run the scanner, if the file
checks clean go ahead and run it then. If it dosn't the program will warn you
and disinfect it. The reason you must open the file (unzip) is because
scanners can't look into an archived file.

Actually the Honor of creating Viruses Belongs to John Conway, he was trying to
develop software that emulated living organisms. He developed the first "Game
of Life". As he created these new programs they became more and more complex
having intricate enviroments that the elements would have to over come in order
to survive.
But these were never allowed to get beyond that scope, Virus programs where
never destructive untill the "Core Wars". Opposing Programmers would create
self-replicating programms that when they encountered other self-replicaters
would try to devour them. Incidently it was called "Core Wars" because the
game itself took place in Core Memory . These young Programmers were actually
quite small in number and never publicly discussed what they were doing. If
any blame is to be attached it should be to Ken THompson who went public with
the process in 1983..... at that point it was "Discovered" by university
students who began creatingthe real nasties ..... Today many strains are just
variation of their original work.

At my school we have some XT's with 2 360K FDD each. Lately we have noticed
that some of the students disks are being over written by the program disk they
were using. Eg some people have found the Turbo pascal files on their data
disks.
I brought in a copy of ScanV66 and placed a validation check on the program
disks (Not the data disks). Scanning showed no viruses (well known ones
anyway). But when we scanned them a week later we found some had had their Boot
Blocks altered.
In some cases the files on the data disk are just renamed to one on the program
disk. Eg we listed "TURBO.EXE" and found it to contain a students pascal source
code.
Could someone shed some light please..

Ken-
This is a continuation of msg.# 156 (I dropped the

Actually, I really should have said "virtually preconceived".
From what I can gather on the topic (I don't yet have a copy of 4096),
they actually redirect CRC/Checksum interrogators to a "snapshot" of
the original file as it appeared before infection.(Someone, I'm sure,
will correct me if I'm wrong or at least add enlightenment.)
The infected file, in the case of 4096, has in reality grown by 4096
bytes and would more than likely hang the system, therefore, which
would lead me to believe that running the CRC check without the virus
TSR would allow you to identify the actual infected files. Also, it
seems like the only way to catch it TSR is to trace the interrupt
vectors (although everyone seems to have a little bit of differing
ideas on this '->)
Until I can get my hands on this little fellow, I guess that I'll
just follow the more logical explanations from the sources with
credibilty and make a judgement from that! Sounds credible. But, as I'v
said before- I sure would like to see it.
I've been following several different message base threads on
this particular virus, with input from users at the basic levels to BBS
SysOps to the AntiViral research community.......I must say, it gets

the CVIA uses to catorgorize viruses? Please? ;-)
2.) I seem to remember mention (No, I don't have my copy of VSUM in
front of my now) of the virus (4096) containing it's own boot sector.
Could someone enlighten me on this , also?
3.) And, under what ? circumstances does the 'FRODO LIVES' msg.
appear and when does it not?
No offense, Patti, but I did think that on a couple of these points
that the VSUM doc was kinda sketchy (I know that is ALOT of work to
compile that baby and continually update, etc.!).
Perhaps with a little more detail, I will have settled my
curiousity and returned to other problems at hand...

Patti- Any luck with last U/L? ,-)

Haven't seen or heard of that one before.... What does it infect? .COM, .EXE,
overlays, boot sectors, only floppies? If you want to send me a copy of it,
I'd be happy to take a look at it as well as pass it along to John McAfee's
group. Snail mail address is:

Santa Clara, CA 95051
It can also be sent in a .ZIP file to my system, though be sure you don't route
it thru anyone, or directly uploaded here to a suspect area that is secured.
Not off-topic at all, that is what this conference is for....

VSUM doesn't necessarily use the McAfee or CVIA categorization techniques to
classify viruses. VSUM's categorization is a bit finer than McAfee's since in
many cases he can group things together for detection/removal purposes.
However, in describing them they don't make much sense that way. I haven't
seen a copy of the CVIA categorization in some time, but I believe they
classified by:
boot sector infector
parasitic file infector
overwriting file infector
Partition table infectors were (I think) thrown in with boot sector infectors
since at the time the only partition table infector was Stoned, which also
infected floppy boot sectors. They also classified by memory resident or
non-resident.
Generally, VSUM classified by memory resident/non-resident, what it infects,
file length change, symptoms, and other characteristics, as well as what virus
the new entry is based on if applicable. In the case of memory resident
viruses, there is a code to indicate how or where it is memory resident.
McAfee and I had a loooonnnnnggggg discussion on classification and naming
awhile back, and "agreed we could disagree" since how he uses the names in Scan
isn't workable for VSUM, and using the VSUM naming in Scan would not serve his
purposes since he needs to group variants in many cases. If possible, though,
we try to use the same names. If VSUM differs, the name that will be indicated
by Scan is indicated as an alias. McAfee's current classification methods as
indicated in VIRLIST.TXT which comes out with Scan also differs from the CVIA
classifications, and is fairly close to VSUM.

Yes, it includes a boot sector, though do to an error in the virus, the
included boot sector isn't ever written to the hard disk or floppy boot sector.
This boot sector is where the "FRODO LIVES" message is....
PF> 3.) And, under what ? circumstances does the 'FRODO LIVES' msg.

Normally, due to a bug in the virus, the message is never displayed. If one
copies the boot sector from within the 4096 virus to a floppy diskette as
sector 0, and boots from it, the message will appear.
Of course, the above bugs may be fixed in a later version of the virus....but
the versions I've seen hang on September 22 when they were meant to activate
the Frodo Lives message.

No problem....A lot of time what makes perfect sense to me doesn't make sense
to others :-). There is always this question with VSUM on where to draw the
line on the descriptions.

Not yet....I'm busy working on analysing a new virus right now, and it is going
to take awhile....will probably be a Whale of a tale when I get done....and I
don't want to say anything prematurely on it.

Core Wars was a simulation system, it was not per se' a breeding ground for the
type of viri that you see today attacking systems and PCs. The programs tested
were called viri in the way they attacked and behaved while operating
within the Core Wars environment. I believe the "arena" used for the "viruses"
was an 8K memory grid, and that the programs/"viri" were limited to that area.
While those programs were not the same thing as what we see today chewing up
our beloved computers, I can say that Core Wars was an extremely enlightening
experience that had the programmers thinking about how a similiar type of
situation could apply to the actual computing world.

This could happen (and has) if you are using disk caching software. That would
be a good place to look first.
