       NEWS! NEWS! NEWS! NEWS!

       Hot from the gossip-mongers on the FidoNet virus echo:

       Tim Caton (The Pallbearer) and a member of
       Phalcon/SKISM, were recently given three month furloughs by moderator
       Frans "Dutch" SomethingorotherAndersssomething for yakking
       about virus exchanges, etc., blah-blah-blah. In "Dutch's"
       own words: they were "excommunicated."

       "Excommunication" translates loosely as "you can still
       post, but no one is allowed to reply to you or they
       will be excommunicated, too."  No word from "Dutch"
       on the inherent 'unworkability' of this arrangement,
       although Caton continues to post and receive responses.
       Apparently, even "Dutch" doesn't believe his own spout.

       As for Caton: "This is just a hobby for me, you hear,
       a hobby!! I could be baskin' in the sun in Florida!"
       he bellowed.

       The "Dutch" policy also does not explain why FidoNet
       fave Gary ("I've been programming in assembly for 14
       years!") Watson is given such a long leash to discuss
       transfer of viral material when newer members are
       continually slapped around for discussing the same
       general topics.

       Speaking of that rogue, Watson, wasn't it he
       he who spent a recent afternoon running SCAN over
       about 650,000 (?!??!) MtE loaded viral samples?
       Now, izzit me, or does this strike you as nuts?
       There is such a thing as being thorough, and then
       there is: CLEARLY INSANE.  Working on your
       Ph.D. thesis Gary? I'm glad I'm not on your
       committee - pass the No-Doze, Quimby, Watson's giving
       his research report on the MtE thisafter...

       SPOTTED ON THE CSERVE VIRUS FORUM: 'Outlaw Joz'
       and 'Bocephus' viruses have been seen plaguing hapless
       corporate stiffs. Our salute to whomever is responsible
       for naming 'Outlaw Joz'!  Obviously, they know how to
       come up with a classy moniker.

       Also seen (hey, this is like being one of those Audobon
       society 'birder' weenies): GEEK virus, a mini-epidemic of
       4096 and NPOX.

       And a special slap upside the head to Virus Bulletin
       'journalist' Mark Hamilton. Hamilton recently sent
       derogatory private e-mail blind-siding fellow VIRUSFORUM member
       Eric Essman as "a sleaze." Amazingly, Hamilton sent it
       to Essman, too (by mistake, apparently).
       Essman promptly turned it into a 'public' multi-mail. Oops!
       Pay more attention to those account addresses, Mark!
       That's an e-mail faux-pas!

       THE GENVIR 1.0: THREAT OR MENACE??

       Have you seen this program:  The GENVIR 1.0 French virus
       generator?

       Outwardly, it's quite an elaborate menu-driven viral
       design suite for "researchers."  But when you get to
       the punchline - the time for it to cough up a virus
       to your specs - up comes a 'crippleware' nag screen.
       Better part with the francs first and register, it
       sez, or no viruses for you!

       Well, c-a-l-l-l-l-l-l Dr. FileFinder!

       In any case, the GENVIR 1.0 remains interesting for a number of
       reasons. First, it's copyright date of 1990 makes it an early
       attempt, if legit, to derive cash from viral code.  This
       predates Mark Ludwig's "Little Black Book" and viral companion
       disk by at least two years.

       Second, it shows that someone thought that a viral programming
       tool had commercial potential, never mind the possible legal
       ramifications.

       Third, since it's 'crippled' shareware, the possibility exists
       that GENVIR 1.0 is the software equivalent of the Piltdown
       Man - an elaborate hoax designed to entice saps into sending
       their hard-earned cash money to an anonymous POB. Haha!!

       Whatever the truth, the GENVIR 1.0 is surrounded in controversy,
       generated, perhaps, by the rage of virus fanatics who spend the
       precious filepoints to download it.

       Is there a GENVIR virus (like MANTA) floating around?
       You tell me if you've got the 'registered' version!!*

       [*Note: if you obtain GENVIR 1.0, better have your pocket
       French-English dictionary ready.  It's 100% frog, but
       still easily doped out if you've got the patience.]

       CASH FOR CODE: AN IDEA WHOSE TIME HAS COME?

       Have you been charging for downloading rights on your exchange?
       Well, if not, perhaps you should.  From what I can tell
       here in lower Slobville, Pennsylvania, viruses and their source
       codes are in high demand.  And a lot of people who want them
       have trouble getting at them, either because they don't have
       a unique virus to upload or don't wish to be bothered with
       programming one.

       Now, there's nothing wrong with this attitude.  After all, should
       you have to hand machine your own Mossburg AlleySweeper before you
       stroll into a firearms store to purchase one?  Of course not.
       If that were so, the locals would be rioting in the streets from
       here to the Florida Keys over infringement of their constitutional
       rights.

       This potential customer base cannot look to the anti-virus
       community for help. Remember, John McAfee has said something to
       the effect that passing on the code of Michelangelo would be akin to
       giving some street urchin a vial of human pathogens.

       So, the field is wide open for the virus exhanges. Rather
       than ask for 'donations', why not simply package viral
       samples in bulk lot and charge what the market will bear,
       depending upon strain demand or prevalence?

       Viral samples could also be packaged with descriptive docs to
       enhance their value and given a guarantee test for 'live'
       quality before put on line. Think of it.  In the long run,
       who do you think will attract more users: the virus exchange
       with hundreds of cryptic archives totally loaded with misnamed
       strains, dummy files, incomplete fragments of code or 100k
       infected games, or the exchange that distributes well documented,
       completely characterized, naked viral samples. [This, of
       course, entails some work.  The archivist will have to go
       through his files and transfer virus-infected utilities/games/etc.
       to a testing area where the virus can be 'trapped' in a small
       generic .COMstub before return to the archive. Documents will
       have to be prepared and formatted, too. This serves a double
       purpose, screening out 'dead' files.]

       Anyway, I think you know the answer.  Think of the virus archive
       as a specialty 'chemical' firm providing lab quality goods for
       interested hobbyists, researchers and the occasional mis-guided
       . . . um, terrorist.

       American gadget freaks, particulary computer hobbyists, are
       inveterate packrats and collectors. In my opinion, those
       interested WILL pay for quality samples, easily obtained
       from straightforward BBS's not saddled with idiotic posting ratios,
       overly chatty menus or disdainful, mocking 'help' prompts.

       Do yourself a favor. Start making some money off your long
       distance collection.

       SCAN 95B AND VCL CODE: A VERY BRIEF RESEARCH REPORT ALMOST
       TOTALLY DEVOID OF EXACTING DETAIL

       The news is out. SCAN 95B detects VCL code as the [Con] virus.
       How long will it take you to retool your custom-designed virus
       so that it can be ready to head back out into the wild?

       The answer: not very long. I recently spent 15 minutes breaking
       SCAN's 'death-grip' on some VCL variants. Simply, the basic
       technique involves making minor changes to, um, well ... heh-heh,
       some secrets have to remain 'proprietary' because there are
       flies on the walls of even the most remote BBS.

       However, included with this issue of the Cryptletter IS a hex
       dump of the MIMIC1 virus, a VCL 1.0 product that DOES NOT
       scan under 95B.  So, you can reverse engineer it if you
       like, but lemme tell ya confidentially, you can probably
       figure it out yourself in less time than I did.

       The REAL point of this abstract again demonstrates the inevitable
       passing of the brute-force scanner.  With the advent of Nowhere
       Man's VCL (and the easy availability of many viral source codes),
       it remains possible to flood any region with a variety of
       easily patched, viral samples. Only software which performs
       functions analogous to something like INTEGRITY MASTER is not
       obsolete. However, will the average American realize this?
       Probably not for another five years.

       ONE FINAL BURNING QUESTION!!

       Why does Mark Hamilton's Virus Bulletin cost so much?  When
       viral sources are commonplace, when there are 'free' magazines
       of technical advice like 40Hex, why is there a
       market for Virus Bulletin?  The answer: some haven't
       caught on.  Give someone you know in the corporate security
       business some source codes, the VCL or PS-MPC, a copy of 40Hex,
       Nuke Info Journal, or, hey, even the Cryptletter.
       Once they know where to find 'em, perhaps they'll weigh the
       cost effectiveness and eventully put Hamilton out of a job.
       Information is not property/goods in the sense that most
       Westerners envision it as!!  Don't pay throat-cutting prices
       for things you have a right to be able to research for free!
       Journals like Virus Bulletin belong in engineering libraries,
       subscriptions bought and paid for by department funds, available
       to all, just like any other scientific journal.

       CRYPTLETTER APPENDICES: AH, THE GOOD STUFF!

       This issue of Crypt contains two hexdumps of live viruses:
       MIMIC.DMP and MIMIC2.DMP.

       Go to the C prompt and type C:\> debug <mimic.dmp .
       Voila! The MIMIC1 virus is ready to go! Same for MIMIC2.DMP

       Some info: MIMIC 1 is an unscanned VCL variant. Encrypted,
       .COM appending, MIMIC 1 activates on Fridays and hunts down
       .EXE's. The target .EXE's are transformed into DEN ZUKO
       'zombies.' When called, the .EXE's/DEN ZUKO 'zombies' will
       load and display the fancy-shmancy DEN ZUKO graphic effect.
       The 'zombies' are not infectious and will NOT scan as DEN
       ZUKO virus.  The astute among you will know that DEN ZUKO
       is a boot infector.  Think of the confusion that could ensue
       when the DEN ZUKO graphic appears on a PC screen, but memory
       scans clean for boot infectors.  I'm sure you see the potential.
       The clever will also observe that the hexdump has a rather large
       'zero' byte stub.  This was the generic stump I attached to
       MIMIC1 so that its encryption engine would turn once.
       The actual virus is about 1000 bytes smaller than the
       final hexdump product.

       MIMIC 2 is an unscanned, encrypted .COM/.EXE infector produced
       from hybridized VCL and PS-MPC code.  On Fridays, MIMIC 2 shuts
       down its rounds of infection and goes on an .EXE hunt to
       transform them into JERUSALEM virus 'zombies.' The JERUSALEM
       'zombies' will go resident when executed, effect system slowdown
       and the characteristic black scrolling screen effect. The 'zombies'
       do not scan, are not infectious and are not overly bright.  They
       will load one on top of the other in low RAM (about .9k) if
       called in multiples.

       And last: CRMBL.ASM - an a86 'falling letters/CASCADE virus'
       effect written so that it is easily shot-gunned into VCL
       1.0 product.  It can also be made into a stand-alone.

       My thanks again go out to Nowhere Man, without whom blah-blah-
       blah.  If you enjoy the Cryptletter, drop me a line, wampum,
       rotten fruit, whatever at the DARK COFFIN BBS.
       [I am also interesting in keeping Cryptletter reasonably
       error free.  I've made every effort to determine that the
       hex dumps and code as provided will work on an average
       IBM PC. However, errors could have crept in in production.
       If you find that the hexdumps do not produce working viruses,
       I want to know. I will gladly supply you with 'working' copies
       if such is ever found to be the case.]

       And, finally, finally, finally:

       If you are entertaining the idea of contributing or writing
       nay-saying commentary to the Cryptletter, please feel free,
       but remember to leave a point of contact if you wish
       any chance of feedback on it. However, because I don't run
       the DARK COFFIN BBS, I take no responsibility for electronic
       archives or documents that may ocassionally go astray upon it.

       I remain your obedient servant,
