BILL GATES: A NINETIES CITIZEN KANE IN SEARCH OF HIS ORSON

WELLES AND HERMAN MANKIEWICZ



While reading William "Randolph" Gates' "The Road Ahead," Crypt

was struck by Microsoft chairman's crying need, a seeming

unconscious urge, to be seen as this age's Charles Foster Kane.

On and on Bill went about his Xanadu, the mega-gajillion Gates

electro-fortress being built as a small republic outside

Seattle.



Like William Randolph Hearst, whom Orson Welles and Hollywood

screen-writer Herman Mankiewicz pilloried as Charles Foster Kane,

Gates appears obsessed about the collection of art treasures hoarded

within his home. Visitors to Gatesadu, like party-goers at Hearst's

Rhode Island-sized estate in San Simeon, will be able to call up

portraits of "presidents, pictures of sunsets," planes, rare stamps,

the Beatles, and reproductions of paintings from the Renaissance.

Like Hearst, who essentially looted everything he saw that he liked

around the world and had it crated and shipped to San Simeon,

Charles Foster Gates has done the same for the digital era.

Unlike Hearst, Gates hasn't run into an equivalent of the Great

Depression and Franklin D. Roosevelt.



However, there is something that every cyber-citizen can encourage.

Bill Gates needs a movie like "Citizen Kane" to balance his life.

You should support this idea.



Hearst was damn near the richest man in the world when Orson

Welles - then in his twenties - collaborated with Herman Mankiewicz

on "Citizen Kane." Mankiewicz was a colorful drunk and writer who'd

been to many, many Hearst parties at San Simeon. As an insider, he

knew enough to make his screenplay hurt. According to the story, Welles

and Mankiewicz ran the script for "Kane" by studio lawyers and then

laughed and joked about how they would stick it to Hearst while working

the phrase "Rosebud" into the movie as Charles Foster Kane's dying word.

In reality, "Rosebud" was supposed to be a cruel jibe: a Mankiewicz play

on the alleged secret name Hearst used when referring to his mistress',

Marion Davies, private parts.



Weird and humorless, Gates is a natural for "Citizen Kaning."

In "The Road Ahead" he takes a paragraph to describe what he thinks

the average person carries every day: a tangle of credit cards, keys,

cameras, a tape recorder, a cell phone, a pager, a few more

electronic gadgets, notepads and last - a whistle to aid in summoning

help. In the bleak world of "The Road Ahead" Gates gives the reader the

impression that he looks forward to a life where everyone's

waking moments are recorded by video cameras, electronic sensors,

and PC's.  It might be "a little chilling" but the benefits outweigh

the negatives.  If you think this is awful, what did you expect when

the only offerings written about Gates that make it to mass market

are controlled autobiography and hagiography by flacks from the

computer industry?



Gates has already acquired his version of "Kane's" Jedediah Leland,

the ex-Ivy Leaguer liberal puppet and drama critic Charles Foster

Kane hired to write for his newspapers.  It's Michael Kinsley.

Is there a Marion Davies in the life of Bill Gates?  Who cares?  Write

a script about it, anyway. Make someone up for the role. Ann Winblad,

a one-time Gates paramour, as a screechy, crossword puzzle-playing

no-talent locked away in the brightly lit labyrinth of Gatesadu,

is one possibility.  Welles admitted portraying Hearst's real mistress,

Marion Davies, as a shrill alcoholic opera-singer was a dirty trick,

nowhere close to the truth -- designed merely to antagonize an old

rich man.



The circle will close when our Orson Welles nears release of

"Citizen Gates."



Enraged by the calumny in it, William Foster Kane vows from Redmond

that it will never see the light of day. He's on the phone to future

president Al Gore, urging the leader to jawbone the FBI into opening

an investigation into un-American activities inspired by the director

of "Citizen Gates."  NBC and Microsoft-NBC start running news clips

attacking the producer as a pervert and philanderer. Gates threatens

to not allow any advertising for the movie or future movies produced

by Hollywood on the Microsoft Network if the industry doesn't bury

"Gates."  Michael Kinsley writes a review after seeing a pre-screening

and, in a paroxysm of self-loathing and guilt over his end as an

instrument of the ultimate computer nerd, declares it brilliant.  He

then passes out hunched over his word processor. Charles Foster Gates

fires Kinsley the next day with a severance check for $250,000.



Then, just as it looks like "Citizen Gates" is about to go into

massive distribution worldwide, the software magnate really starts

putting on the pressure.  Gates instructs his army of lawyers to begin

a $2-billion dollar SLAPP civil suit against the studio and producer of

the movie.  The campaign is a partial success.  Release of "Gates" is

restricted to art houses.  It receives rave reviews but dies on

the vine.  The producer moves to Europe to escape Gates'

bully-boys.  The only work the famous director can get as he nears

the end of his life five decades later is as a pitchman for lousy wine.



Finally, at age 93, William Gates dies. A recluse in his monster

techno-home for years, Gates fell off the national podium when

the glistening world he predicted in "The Road Ahead" became

the cruel cement of reality.  Unfortunately, the Middle Class

buying power that financed Gates' empire in the 80's and

90's was also put out of work, obsolete, in his version of the

future. Unemployed or underemployed, it could no longer afford the

computing machinery needed to run and enjoy the software of Charles

Foster Gates and with that, the Microsoft magnate's world collapsed

quietly and without ceremony.



A butler and a nurse reported the last word of Charles Foster

Gates, in bed, as a gray plastic mouse slipped from his cold

grip to break silently on the floor.

PERILS OF WISDOM: DANISH VIRUS WRITER'S BOOK ON VIRUS DETECTION

SURE TO BE COLLECTOR'S ITEM



Faithful readers of Crypt Newsletter know that when they see

the tired hacker bromide "Information wants to be free!" it's

time to grasp the wallet firmly because a ripoff is in the

making.  Danish programmer Rune Skardhamar's computer virus

book for Academic Press ($35 cash money) drop-kicks the reader

with cliches like "Information [on computer viruses] needs to be

free" in the introduction and goes steadily downhill with a

collection of humorous errors, non-working computer virus samples

pulled from virus exchange BBSes and rudimentary anti-virus

programs which, if assembled, either corrupt computer files

or pronounce virus-infected programs clean.



Skardhamar cites Fred Cohen in his reference list but amusingly

goofs up the name of the Lehigh virus and the university - he calls

them "Leigh" - where Cohen spent time prior to the outbreak

of the former. This is an interesting error because the Lehigh virus

also led to the formation of the Usenet's comp.virus newsgroup, another

citation in Skardhamar's bibliography.  The last time Crypt checked,

both Fred Cohen and Virus-L/comp.virus seemed to know how to spell

Lehigh.



Anyway, another source for the book is phalcon/SKISM's 40Hex magazine

which Skardhamar calls possessed of a "propagandist" view of computer

viruses. Paradoxically, one of the viruses included in the book is a

direct action .COM-infector produced by the earliest version of the

phalcon/SKISM MPC virus-maker software which, as published, does not

work.  Skardhamar's PS-MPC virus sample contains a small error in one

of its DOS function calls that ensures its code cannot be written

to host files and while it's an easy correction for most people

familiar with computer viruses, it's probably beyond the ability of

the audience of beginners at which the book is aimed.



Purely by serendipity, this is to Skardhamar's advantage.



Here's why:



"Virus Detection and Elimination" also comes with a companion diskette

containing some TASM-compatible assembly language programs written

by the author for the purpose of detecting and disinfecting the viruses

included in the book.  The "disinfector" for the PS-MPC virus is quite

novel in approach:  It cleans the virus by truncating infected programs

by the virus's length and then overwriting the remainder of the

program with garbage from memory, totally corrupting the file.

This appears to be another laughable gaffe which most readers

won't run across simply because the virus the book's "cleaner" is

paired with isn't contagious.



Another interesting example of Skardhamar's approach to virus

detection is the scanning program designed for a companion virus

included in the book.  The virus, written by "Wonko the Sane" and

dubbed "The slightly orange avenger" works if you detect the typo

in the code and add a space. (Even for those who don't recognize

it, the error is so small that running the instructions for the

virus through any assembler will flag it and prevent compilation

until a correction is made.) However, the scanner for "Wonko the

Sane's" companion virus doesn't work, instead inspecting infected

files, the binary images of the virus, and gaily announcing to the

user "OK"!



Other virus programs included in the book are a variant of the

Trivial family of overwriting viruses, a DOS .EXE-program infector

and a Stoned derivative with a program launcher for infecting

diskettes with it. Although not all of the programs on

Skardhamar's diskette were tested, the reader might approach the

code (particularly the detection and disinfection routines) slowly,

given the performance of other examples offered upon it.  Indeed,

disclaimers peppered liberally across the diskette balefully proclaim:



"No responsibility whatsoever will be taken for any damage

incidential [sic] or otherwise resulting from the use or misuse of

this program. Neither will responsibility be taken for omissions

or errors in the code, comments etc. You are now resonsibly [sic]

for your own actions."



This type of indirect warning that the reader is about to suffer

a computer hotfoot is paraphrased straight from the computer virus

underground.



The point to be made here, and which I suspect was a bit beyond

the technical editors at Academic Press when they went over the

manuscript - is "Virus Detection and Elimination" is in many ways,

simply the product of trolling virus exchange BBSes and refitting

the subject matter recovered in a more expensive-looking suit.

It's fair to say that lay readers will find portions of "Virus

Detection and Elimination" extremely fascinating

but it would have been easier on consumers to give it a title like

"What I Found After a Few Months of Visiting Virus Exchanges on

BBSes and the Internet" since there is nothing in the book's enclosed

programing that is of much practical use in "detection and

elimination." Of course, a good editor could shorten the new title

to something a bit more zippy and saleable.



Additionally, "Virus Detection and Elimination" covers technique, also

apparently lifted from 40Hex and other files from the computer

underground, on making viruses refractory to trivial attempts at

analysis. In its computer virus history portion, retold again is the

legend of Bulgaria as computer virus factory for the world. The story

has been repeated and exaggerated so often for magazines and newspapers

it's now an inescapable tenet of computer virus lore.  An enterprising

individual in search of a few quick bucks would be smart to consider

printing up some black T-shirt's, perhaps emblazoned with "I survived

the Bulgarian computer virus factory!" and setting up a kiosk at

hacker conventions in 1996.



Dave Hannon, an editorial staffer at Academic Press, commented to

Crypt that English was Skardhamar's second language.  For readers

of "Virus Detection and Elimination," it's, uh, noticeable.  As for the

faults in the anti-virus programs and viruses included with the book,

Hannon also conceded appraising the material and code included in the

book was beyond the technical ability of its American publisher and it

fell to the author to look over his own material for mistakes of this

nature prior to publication.



"Please do not use the information carried in this book to wreck

havoc," Skardhamar writes near the end of his book. He means "wreak

havoc."  Further, he writes, "Any stupid fool can make a virus; the

genius is the one who will put the coding techniques to some creative

use."  In view of the "code" included with "Virus Detection and

Elimination," this statement - as Skardhamar's parting shot - is

a bone-crusher. His bones, though, not yours, making the book

a solid collector's item amid the increasing "lore" devoted to

the world of computer viruses.





SEX, LIES & COMPUTER TAPE: ON THE TRAIL OF KEVIN MITNICK IN

TSUTOMU SHIMOMURA'S PAEAN TO HIMSELF AND JON LITTMAN'S

"THE FUGITIVE GAME"



At least two volumes will catch your eye this month as US publishers

gear up for the Kevin Mitnick-money chase: Tsutomu Shimomura's

"Takedown," an auto-hagiography of the author that only incidentally

deals with the dark-side hacker, and writer John Littman's "The

Fugitive Game" which holds up much better than "Takedown" in

terms of human interest, computer shenanigans and controversy.



"Takedown" (Hyperion) is an unpleasant, tedious read revolving

around the reality that while Shimomura may have been able to track

Kevin Mitnick, he can barely write an interesting story even with

New York Times reporter John Markoff to prop him up.



"Takedown's" turgid quality is magnified by Shimomura's intent

to sing a paean to himself and his computer feats.   He's so

hell-bent on it, in fact, he comes off unselfconsciously repellent.

In "Takedown," everyone but Shimomura and his cohort, John Markoff, are

criminal worms, in the way, or country bumpkins and dolts.



The reader will feel particularly sorry for the FBI's Levord Burns. As

written up in "Takedown," Burns is a fossilized piece of wood,

intermittently described as either always home in bed fast asleep when

the game's afoot, baffled to the point of silence by the technical

nature of the pursuit of Mitnick, or falling into a doze on the

telephone while being badgered to perform some minor duty connected

with the chase. The Computer Emergency Response Team is a vague,

inefficient, slow-moving bureaucracy. The NSA is another big, dumb

government institution to Shimomura, even though he's trying to squeeze

funding from it at the beginning of the tale. Andrew Gross, Shimomura's

Renfield, is always screwing things up, tampering with files, messing up

evidence or being a stumblebum for our cyber-Poirot. Julia Menapace, the

girlfriend, is a co-dependent who can't decide to throw over her

ex-paramour - John Gilmore of Sun Microsystems - fast enough for our

hacker tracker, even while Shimomura's being a cad with her in Gilmore's

home.



At least fifty percent of the book is devoted to Shimomura explaining

his life of privilege in the same detail he uses to describe the

names of his computers.  Eventually, the battle is joined and our

cyber-sleuth and his entourage light out on the trail of Mitnick,

blamed for invading Shimomura's computer over Christmas.  It would be

exaggerating to say this is interesting. The details of the

Mitnick-hysteria and Shimomura chase have been repeated so often in the

media already none of the story is fresh except for parts near the

end where Shimomura grudgingly admits that it might not have been

Mitnick who was into his computers in the first place, but an unknown

collaborator who finally panicked and begged him off the chase

in a message on his answering service after Mitnick was in custody.

Yes, but Mitnick and his collaborator called Shimomura names and made

dirty jokes about our hero on an Internet talk channel, dammnit!!

That made it personal! Nyahh, nyahh, nyahh! And Mitnick was reading

other people's mail on the Well and into Netcom!  Of course, Kevin

Mitnick is no hero but Shimomura's a thin, thin choice for

a celebrity cybersavior.  Ultimately, "Takedown" is completely lacking

in the kind of humanity, self-effacing wit and style of Cliff Stoll's

"The Cuckoo's Egg," a prior classic on hacker takedown, mostly because

its author can't help being a boor.



However, there is a choice on bookshelves. Jonathan Littman's

"The Fugitive Game" (Little, Brown) is better.  For reasons probably

having to do with the general knowledge that Littman was writing a

book about hackers, Mitnick started calling the reporter regularly

during the same period of time Shimomura was on his case.  And unless

Littman's making everything up, the result makes Shimomura and John

Markoff look like turds.



Littman's book bolsters the idea that it wasn't Mitnick who was

into Shimomura's system and that what the San Diego scientist did

wasn't particularly special -- a Seattle man, Todd Young, had

tracked and spotted the hacker in that city long before Shimomura

came along but allowed him to escape through a combination of ignorance,

bad luck and disinterest in the gravity of Mitnick's alleged

criminal doings.



In "The Fugitive Game," Littman accuses Markoff and Shimomura of

a cozy relationship stemming from an old article in WIRED

magazine on cellular phone crime.  Markoff's original article

anonymized the identities of the cell phone hackers because they

were playing around with illegality.  Littman insists they were

Shimomura and Mark Lottor, an acquaintance of the author and hacker

Kevin Poulsen.  The story goes that Shimomura reverse-engineered

code designed to program an Oki cellular phone for the purpose of

reprogramming it into a transmission snooper, or something like

that.  When Shimomura's computer was broken into, the material

was copied off it. Littman draws the conclusion in "The Fugitive

Game" that Shimomura, in addition to being fired up over the invasion

of his system, was also embarrassed by the loss of this software,

software he engineered, the author implies, under quasi-legal

circumstances. Indirectly, "Takedown" supports this argument.

Shimomura obsesses over the loss of a file which a reader of both

books might guess contained the Oki software.



Throughout "The Fugitive Game," for the first time in book, Mitnick

is portrayed as a real human being, not a caricature. He has a sense of

humor, regrets, weaknesses, and a pack of serious neuroses stemming from

his jail-time and uncontrollable cyber-fame. But the author isn't

easy on him: Mitnick also comes off as a hardened con-man who relishes

snooping other people's privates, cruel treachery, and duping the

unwitting into compromising themselves or their places of employment.



At one point Mitnick indicates something very interesting about

users of Pretty Good Privacy.  Some users of it on the 'Net,

particularly those running services hooked directly to it,

keep their PGP software on the public host.  Mitnick laughs at the

lapse - he implies it's been a simple matter for him to put a

backdoor into the PGP source which deliver the keys and passphrase

of the user to another spot on the host he's invaded, compile it and

replace the original host copies.  From here, it's simple, he maintains,

to read their encrypted mail -- this in a conversation on Mark Lottor

in which the hacker says he's read Lottor's electronic correspondence.





If there's a need for a bona fide, hiss-able villain in "The

Fugitive Game," Littman produces one: Justin Petersen.  Petersen

aka Agent Steal, is a side-plot in the book: a pathological

liar, car thief, and con-man who portrays himself as a

combination cyberpunk/heavy metal rock 'n' roller.  Fond of

artificially busty stripper/hookers from the sleazy end of Sunset in

Hollywood, Littman paints Petersen as the maximum disinformer

and criminal -- a squealer for the FBI who embarrassed the agency

by embezzling Social Security funds and then going on the lam when

lawmen tried to reel him in. "The Fugitive Game" has him

bargaining with the FBI for tidbits on Mitnick's whereabouts.



Littman wraps up "The Fugitive Game" with broadsides at Shimomura

and Markoff. With Markoff playing Mitnick as the enemy of all

computerized civilization on the front page of the New York Times,

the stage was set to ensure maximum hysteria and the subsequent

introduction of the reporter's friend, Tsutomu Shimomura, into

a carefully arranged media spotlight. Behind the scenes, Markoff's

agent was negotiating a big money deal - approximately $2 million,

says Littman - for the reporter and Shimomura, three days _before_

Markoff put the physicist on the front page of the New York Times.



Ironically, the increasing cynicism which is the natural crop sown

and cultivated by this type of media rigging for the benefit of men

of privilege is a tale of treachery and contempt, too, but one that

goes well beyond hacker Kevin Mitnick.





Additional notes:



(From July - August - October 1995)



Both the government and Kevin Mitnick's attorneys appeared to be

working privately to settle the case against him without a trial

in late 1995.



In August, Mitnick appeared in court dressed in a conservative

suit and tie for arraignment on a 1989 probation violation.

Mitnick was on probation for an earlier hacking case when he fled

California in November, 1992.



Although no one was talking, it was believed Mitnick's representation

and authorities "were trying to reach an agreement under which Mitnick

would plead guilty to a number of charges in order to avoid going to

trial in all the jurisdictions across the country where he may

[or may not] have committed electronic crimes during his flight."



"We're looking for him to take responsibility for the entirety of his

conduct," said Assistant U.S. Atty. David Schindler. At the time,

Schindler would not say what type of sentence he was driving for.



In various articles printed throughout the news media, Mitnick

was reported able to  plea-bargain his infamous early-1995

cross-country hacking and media jaunt into a sentence that commits him

to about eight months in prison, according to John Yzurdiaga, his

attorney.



Mitnick, for part of the plea, will concede guilt in possession

of stolen cellular phone numbers, one of twenty three federal

charges - all concerning cellular phone fraud - against him.









JANET ENDRIJONAS' "DATA SECURITY," A CLEARLY WRITTEN INTRODUCTORY

BOOK ON COMPUTER SECURITY CONCERNS



"Data Security" (Prima, $34.95), although slightly overpriced,

is a clearly written introduction to computer security for

laymen.



While not going over the book point-by-point, one of the more

interesting sections is devoted to computer viruses and what

Rob Rosenberger, a contributor to the section, dubs "false

authority" syndrome.  The condition, as Rosenberger describes it,

has contributed to the body of disinformation bandied about in

public on the subject of computer viruses. It addresses the same topic

Crypt Newsletter has touched upon for the past two years: the

unreliability of sources in the mainstream general news media and

computer industry and the lack of proper skepticism leveled at them.

It's a ring-around-the-rosy phenomenon in which "experts" cited in

one news piece become the same experts used by other reporters and

editors jumping on a story as it bumps over the wires.  The result:

the same names appear again and again in multiple places with no

question of their credentials as "experts," simply because they

appeared in a primary newspiece.  The logical drawback of this is

that if the "expert" is someone who has no idea what he's talking

about but happened to be in the right place at the right time when

a reporter needed a source, the phlogiston he's peddling becomes

magnified over and over until it becomes the accepted version, even

if it's incompetent or utterly self-serving.  Information and history on

computer viruses has always been plagued by the phenomenon, the

best example being the hysteria surrounding the Michelangelo virus

non-crisis of 1992.



Pointedly, Rosenberger writes while skewering editor Jeff Duntemann

of PC Techniques magazine:  "Jeff Duntemann . . . editor of PC

Techniques, has seen this trend and likens it to what he calls

the 'Green Paint Factor.' If you want to extol the virtues of

a can of green paint, and the best you can say is that it's _green_,

well -- it's probably not good paint."  Rosenberger interjects:

"If you want to quote somebody about computer viruses, and the best

you can say is that he edits a computer magazine . . . " Ouch.



"Data Security" is a good, non-patronizing read for the average PC

jockey and is especially user-friendly to those just stepping off into 

cyberspace.







SYMANTEC SUPPORT OF CENTRAL POINT ANTI-VIRUS: OBLIGATED BUT RELUCTANT



Crypt Newsletter often sees on-line users inquiring about support for

Central Point Anti-virus.  Although the company was gobbled up by

Symantec some time ago, the Norton Anti-virus effort continues to pass

on updates to the program, some of which produce hangs and errors

in the software, often further cruelly confounding the helpless.



The newsletter has also noticed Symantec employees have little

enthusiasm for supporting Central Point Anti-virus. The issue is of

some interest due to Central Point Software's nettlesomely large

consumer base. If Symantec is not enthusiastic about supporting

Central Point licensed software, even to the point of rubbishing it

in public comment, why support Central Point Anti-virus and its

offshoots at all?



Crypt posed this question to Michael Messuri, a Norton Anti-virus

research specialist, in the National Computer Security Association's

InfoSec forum on Compuserve.



His comment:



"Symantec is obligated to provide support for [Central Point Anti-virus].

(I am not aware of the wording of these obligations). However, it is my

opinion that users should be aware of the limitations of [Central Point

Anti-virus] so that they may make the best choice possible for their

antivirus protection policy.  While I will provide the best support

possible for [Central Point Anti-virus], I will also inform the user of

the problems of using [Central Point Anti-virus].



Further, Crypt asked, why not just send flyers to the Central Point

Anti-virus user base saying: "The product's not supported, we liquidated

the licensing company, we think it stinks from a technical standpoint

and we're dropping it from our on-line libraries.  As a substitute, buy

Norton Anti-virus."



Messuri replied, "On a personal level, I would love to make these kind

of decisions but, sadly, I am only a common worker in the bigger picture

of things and thus am not aware of the many decisions behind these types

of actions."



Crypt appreciates Michael Messuri's candor and hopes the recirculation

of it doesn't result in an unwanted seminar at Symantec corporate.







SONGS OF THE CYBER-DOOMED, II: THE TERMINATOR TERMINATES THE FIDONET'S

INTERNET E-MAIL GATEWAY



Earlier this year, Burt Juda, an administrator for the FIDOnet's

Internet mail gateway announced the network would lose the gateway

as a consequence of a denial-of-service attack on his system

carried out by a couple of the network's ex-sysops, one

of whom - The Terminator - is familiar to Crypt Newsletter followers

of the FIDOnet "cyber-doomed" news stories (Crypt 27 - 28).



Juda commented recently in a post widely distributed by various

on-line networks:



"Effective March 1, 1996,  the Internet Gateway at 1:1/31 will

be shutting down.  At that point, there will be NO MORE 'default'

gateway for electronic mail inbound from the Internet for [the US].



"The reasons for this termination of service are numerous . . .



"Most recently, an excommunicated SysOp has gone on a rampage of

forging subscription messages to subscribe numerous FidoNet

addresses to . . . unwanted Internet mailing-lists

in a deliberate attempt to 'break' [FidoNet] routing . . . and

the gateway structure."



Further, Juda writes, "I can no longer deal with the voluminous

netmail being received from [people] querying what has happened to

their inbound [electronic mail] coming [through the affected gateway].



Juda added he no longer had the time to support the  service when

cyber-denizens "continue[d] to break the rules of its use and

bypass . . . controls."



The Fidonet Internet-netmail junction, which provides service to the

community of amateur, pro and semi-pro BBS sysops and callers who use

the FIDOnet nationwide, was brought to the point of collapse

as a result of mass electronic mail forgery by The Terminator and

another collaborator.



In late 1995, The Terminator and a partner spent an evening ramming the

Fidonet-Internet gateway in Piscataway, New Jersey, with posts forged to

look like they originated from as many FIDO-sysop network e-mail accounts

as could be gathered. This is quite a few -- thousands -- as it turns out.

Many, many of these posts were simply subscription requests to Internet

mailing lists.



Subsequently, the Fidonet/Internet junction was overwhelmed with the

volume of nuisance mail and hung.



The Terminator had been involved in disruption of the FIDO Virus

Information echo and others throughout 1994 and 1995 with re-directed

spam-mail.  The mail-bombs, rammed through unsecured FIDOnet mail links

from Europe, Israel and the United States, consisted of virus source

code interspersed with a great deal of text hardcore filth dealing with

transvestism and scatological material fabricated for the occasion

and/or cross-posted from an adult-oriented network.



One example of such mail:



"Are there any persons out there that get off by watching a woman pee?

There is just something about seeing and hearing a woman pee.  Not sure

if I am into getting peed upon, but I am always open to new adventures."



Because of the level of trust in the inherently wide-open, difficult

to secure FIDO technology network, FIDO administrators and sysops 

were never able to completely plug the system breaches exploited by 

The Terminator, leading more recently to the collapse of its Internet 

gateway when expanded attacks overpowered the message handling capacity 

of the junction and the patience of its administrator.



At the time of the original nuisance mail rammings in the FIDO

Virus Information message base, some BBS operators monitored their

systems more closely for obviously fake mail; others attempted to

secure their automated mailer software with mixed success. Still

others took the expedient cure. They simply dropped service on

the special interest groups affected, the same answer given to the

problem by the FIDO/Internet electronic mail gateway administrator.



Shortly after the initial failure of the FIDO/Internet mail gateway,

The Terminator contacted Crypt Newsletter from Moberly, Missouri, to

point out the interruption in service brought about by the attack.



"The FIDO/Internet gateway is crashed," he said.



The start of attacks on FIDOnet computer virus information message

feeds in 1993 were attributed to Paskell "Geno" Paris of Oklahoma City,

a FIDO sysop and self-styled "technopath" who waged a guerilla war

for control of a small section of cyberspace moderated by Ed Cleton,

a European host of virus information topics on the FIDOnet.  Paris was

later indicted and convicted on fraud charges, crimes unrelated to his

activity on the FIDOnet. As a consequence, Paris served time in state

and federal prison. The Terminator carried on Paris' mail war with Virus

Information moderators Jeff Cook, a representative of Thunderbyte

Anti-virus, and his successor, Allen Taylor.  During the period and

as a result of repeated mail bombing runs, The Terminator was banned

from the message base. Nuisance mail-rammings of virus source code

and forged messages, however, continued to plague the FIDOnet echo.





I PUT A SPELL ON YOU: THE CURSED HARD DISK PHENOMENON UNDER

MS-DOS



Crypt Newsletter recently ran into an old, obscure fault in Microsoft's

DOS operating system. Referred to as the "cursed hard disk" by

researchers in IBM's anti-virus software development group, it's a real

eye-opener. When the cursed disk fault is created on a machine running

versions of MS-DOS from 4.00 onward, the system runs aground in an

unproductive loop while parsing the system file IO.SYS.  The real

crusher occurs when the nonchalant user tries to start the machine from

his fall-back position, the trusty A: drive. In goes the boot diskette.

The machine is restarted smartly and it . . . hangs.



Oops!  Must have not seated the diskette correctly.  Restart . . .

and the machine . . . hangs. Curses, still some lint on the platter!

Reboot again and the machine . . . hangs.



Your neck suddenly breaks out in a cold sweat.



From the standpoint of current PC users, the problem is remarkably

ancient - dating to 1992 when Mike Lambert, a computer security

professional, stumbled across it and wrote extensively on it in an

interesting paper entitled "When the magic floppy won't boot."



"The hard disk access light remains on," during the fault, Lambert

writes.  However, because the machine can't be started even when using

the diskette drive, "A technician is likely to diagnose a [hard disk]

problem because of . . . the disk's access light being on. The technician

will probably use component replacement techniques to verify [his]

suspicion. When the PC boots properly from a new [hard disk]

. . . this will tend to confirm the diagnosis that the [disk] has failed.



"The result is a perfectly good disk classified as failed . . . The user

is forced to recover from any backups available."



The error isn't hardware-based although it often stuns those who run

across it into thinking so the first time they experience it.  Instead,

it lies within the operating system's handling of data written in the

partition table.  Lambert and his colleague, Charles Moore, dubbed this

the "circular extended partition" fault which is - technically - a good

description for it, since the problem involves a futile, circular

processing within the operating system.



For those who encounter the problem, Lambert's paper indicates it's

difficult, without understanding what is transpiring, to get in

front of the fault before it runs the PC aground. The error lies

in the system program IO.SYS, where it evaluates the partition table

data for the purpose of mounting file system volumes attached to the PC.

If the error is present, IO.SYS loops fruitlessly on the partition

table, which is altered in "cursed disk" syndrome to point to itself as

the beginning of the booting volume, and the machine cannot be started.



One logical place to intervene is with code loaded from the boot

sector on the booting diskette.  A fix circulated with Lambert's

paper did just that: It provided the user with a custom-made

diskette with code written into the diskette boot sector to read

the partition table data for evidence of the "cursed disk" corruption,

which is found in the MS-DOS description for what are known as

"extended partitions." If found, it writes a temporary fix - simply

altering the byte which tells DOS to support "extended partitions"

within the partition table data, so the machine can be started normally.

The error can then be cleaned up completely and the system restored to

proper working order with standard partition table editing software.



Once one understands the nature of the fault, this cure almost sounds

easy to do. And, in fact, it is. Keep in mind, however, that the great

majority of current diagnostic disk management and security/anti-virus

software programs provide no help for this problem unless it's picked

up before the machine is restarted and the changes take effect.

Fortunately, the "cursed disk" phenomenon has remained quite rare

since 1992.



More interestingly, the September issue of Virus Bulletin contained

comment on a multi-partite virus that introduces the fault to make

itself difficult to remove from hard disks infected by it. The virus,

called Rainbow, infects .COM and .EXE programs as well the master boot

record (MBR) of hard disks, inserting a 25-byte change in the target at

physical sector 0,0,1 pointing to the rest of its code copied to space

assumed to be unused on track 0 of the hard disk and spanning physical

sectors 0,0,2 - 0,0,5. An uninfected copy of the original MBR is copied

to 0,0,6.



Rainbow introduces the "cursed disk" fault to make itself difficult

to remove if the machine is started cleanly from the A: drive.  In

this case, the idea the virus writer had in mind was to make the

machine appear frozen.  When the machine is started from the

Rainbow infected hard disk, the virus loads first and produces

the original uncorrupted partition sector at 0,0,6 for the machine,

masking the problem. Bill Arnold, a researcher in the anti-virus

software development group at IBM's T.J. Watson installation commented

Rainbow was not considered a threat in the wild.



In interview, Mike Lambert said he first noticed the fault in 1992

when asked to troubleshoot a disk security program that had been

installed on a PC, one that was proving difficult to remove.  The

program used the "cursed disk" error to secure the machine, making it

impossible to bypass by booting from the standard bootable floppy.  This

led to Lambert writing the "When the magic floppy won't boot" paper

with collaborator Charles Moore.  The use of the "cursed disk" fault

as a basis for a disk security program, while unusual, is not without

precedent.  Patrick Toulme, the programmer of Virus-90 and Virus-101

and a number of powerful systems level software utilities, has fielded

a disk securing program utilizing the error to halt the machine when

starting from a diskette.



More recently, Crypt Newsletter recovered a software boobytrap

written by Stefan Kurtzhals, a German programmer who associates himself

with an organization called Virus Help Munich and dabbles in the

writing of anti-virus software. Kurtzhals wrote this software

bomb, called Megatest, in an attempt to trick a more successful

competitor with the "cursed disk" effect.



In electronic mail obtained by Crypt, Kurtzhals said, "I have quite

good [connections] to both AV companies and virus coders, but it's not

perfect yet. I need more connections and information. Hmmm, quite funny.

I get both AV software and new viruses for beta testing."  Kurtzhals

added the "cursed disk" fault used in his boobytrap "is also known to

almost every better virus coder. It will be mentioned in [the

Australian virus-writing magazine] VLAD#6, too. I've seen a preview of

some it's [sic] parts."  Kurtzhals anti-virus software (not the

"cursed disk" boobytrap), called Suspicious, is available from the

Munich, Germany, Web-site WWW.LEO.ORG.



Lambert said to Crypt Newsletter he has been informally notifying

the various developers of DOS of the "cursed disk" fault since 1992.

Bill Arnold of IBM said current versions of PC-DOS are no longer

vulnerable to "cursed disk" syndrome.  Lambert added Novell DOS has also

been cured of the problem.  MS-DOS versions 4.0 to current still

carry the bug, a not insubstantial user base.





Additional notes:



1. This bares mentioning one more time in case readers have decided the

sky is falling because of MS-DOS and the "cursed disk" phenomenon.

Time and the inexorable march of technology are slowly eroding the

annoyance of the fault. It is quite rare. And current versions of PC-DOS

and DR-DOS eliminate the problem. Therefore, booting from any current

DOS other than Microsoft's flavor will unlock the "cursed disk," and enable

remedy of the problem. A Rand Corporation scientist in Santa Monica was

recently overheard muttering something that sounded like "Microsoft" and

"suckware" under his breath.



---Other fixes for a "cursed disk" are contained in Lambert &

Moore's original paper, "When the magic floppy won't boot" from

the Web site: http://www.frontiernet.net/~mlambert



The ARF anti-virus software, reviewed later in this issue, creates a

rescue system disk invulnerable to the "cursed hard disk" fault.

It is similar to the Lambert/Moore fix in that it allows a user to get

in front of the problem by putting a jack-handle for system restoration

directly into the code loaded from the boot sector of a rescue

diskette. Another option is to start the machine with an alternative

to Microsoft-DOS and use a program with the functionality of Netz

Computing's Invircible ResQPro/ResQDisk that can automatically correct

corrupted partition table data snarled in this manner.



2. Patrick Toulme's Virus-90 and Virus-101 were demonstration

file-infecting viruses that confined themselves to operation on

floppies in the A: or B: drives.  Virus-90 contained the name and

address of its author, Virus-101 was encrypted, packed a video display

and an activation that overwrote non-system floppy boot sectors with a

message that is was a "safe, educational virus utility," furnished

to/for John McAfee.





GRAB BAG: BOZA - THE PAUSE THAT REFRESHES -or- ANOTHER KNEE-JERK

PRESS RELEASE COMPUTER VIRUS STORY



As Crypt Newsletter went to press, the Associated Press triggered

another round of ridiculous computer virus alarms with a story

on the Boza computer virus, an admittedly barely infectious

parasite on Win95 executables.  Attributed to the VLAD Australian

virus-writing group due to the equivalent of a computer underground

press release embedded in the virus extolling VLAD members and their

technical virtuosity vis-a-vis computer viruses, Associated Press

reporter Sue Leeman issued a news brief and it echoed internationally.



In a pattern of action and reaction that has become standard for

most computer virus stories reported in the mainstream press, the

Boza piece generated countless questions from on-line users who thought

they were in danger from it, although realistically they were

statistically more likely to be hit by an automobile than the virus in

their lifetime.  The original Associated Press attributed Sophos' Paul

Ducklin saying the Boza virus wasn't on the loose, but most subsequent

news stories and fragments derived from it, including copycat

press releases from other vendors, stripped this from the original.



The results were predictably confusing.  Some PC users who did not

even have Windows 95 installed on machines concluded they might have

been exposed to Boza.



From the Associated Press: "Analysts [meaning anti-virus software

developers at Sophos, a United Kingdom-based company] have named the

virus Boza after a Bulgarian liquor 'so powerful that just looking at

it will give you a headache,' [Paul] Ducklin said."  It was a colorful,

ingenious turn of phrase which had nothing to do with computer viruses

per se but which made for a more interesting line of discussion.



It being cyberspace, of course, opinions tended to differ. In the

National Computer Security Association's Anti-virus forum on Compuserve,

Zvi Netiv, author of the Invircible anti-virus added, "I had Boza quite a

few times with my [Bulgarian] in-laws. Boza is a home-made beverage,

prepared from ground barley, left fermenting in water for a few days.

It's milder than beer, looks like thin oat porridge and smells like

. . . well, if you once visited a beer brewery, then you know what

[it smells like] -- Quite far from what you would call liquor and as

strong as camel's milk."  Netiv added worrying about the Boza virus

was absurd.



The Boza mini-panic illustrated the need for more and more media

criticism, particularly when it comes to technology stories.  A

few rules of thumb to keep in mind when dealing with this type

of thing are:



1. Computer virus stories are the best vehicle in which software

developers selling cures can pimp for their products. Even if the

virus is shown to be pathetic as a public menace, interest in those

cited peaks transiently during the run of the story. This amounts

to cash money in software sales and on-line time spent through

commercial services offering information or software fixes through

download, even if it's relatively unnecessary.



2. Being the first vendor mentioned in a story like Boza throws

competitors immediately on the defensive, scrambling to recover

and fueling the story in the process.  Even though competing

companies may have known of a virus weeks previously and quietly

written cures into software as the usual course of business, the

average PC user - after reading this type of story - will be given

the impression everyone else was asleep at the wheel.  This sets

off a chain reaction in which competitors quickly release copycat

press releases which drive developments and strip more information

from the primary seed in an effort to maximize individual product

exposure. Those vendors who don't do this often face tons of

witless questions from those needlessly frightened by the news in

on-line computer help forums. They also face a transient image

that they've been caught flat-footed, and being called the equivalent

of cyber-chumps by vendors more successful at generating press. From

a consumer standpoint, this leads to counter-productive behavior in

which vendors burned by the lack of exposure gear up to generate

even more press releases on potential future threats _before_

they materialize.



3. It encourages some vendors to increase their contact with

known active virus-writers and their groupies so that they will be

the first to receive new viruses which, may or may not (more often

"not"), work.  This is a nasty spiral which tends to encourage

virus-writers to produce even more than they usually would for

their "audience."



A central point that should not be missed is that stories like

"Boza" are symptoms of a kind of contempt in which the computer

industry holds consumers.  In this case, the contempt is shown

in the use of virus-writers and computer viruses as sales and

marketing tools, magnified by the exploitation of the relative

ignorance and ease of manipulation of the news media and average

PC user.  In a more general sense, the computer industry, as a

whole, has always shoveled a great deal of marketing effort into

generating well-publicized "problems" for which it conveniently

provides the snake-oil. Boza was another in this tradition.





VIRUS CD-ROM SALES TOP 1400



Mark Ludwig, author of "The Black Book" series on computer viruses and

the publisher of a widely distributed CD-ROM of the programs and

related material commented to Crypt that sales of the compact disc

had topped 1400.  The disc sells for $100 cash money/copy which

grosses to $140,000 collected in sales of bulk computer viruses

through American Eagle, Ludwig's parent Arizona-based company.  Ludwig

added that a second edition of the virus CD-ROM was envisioned

containing about twice the data volume of the original in computer

viruses.





REALLY BLEW'D, SCREWED & TATTOO'D: BLACK BARON GETS 18 MONTHS IN GAOL



In mid-November 1995, the English trial of virus-writer Chris Pile

finally ended with an 18-month prison sentence for the author of

the SMEG computer viruses.



The English newspaper The Independent referred to Pile as a "'mad and

reclusive boffin' who wreaked havoc on computer systems by spreading

[viruses] . . . across the world . . ." [Webster's New World Dictionary

informs readers "mad boffin" is Brit slang for "mad scientist."]



"'I dare say you were looking forward to reading in the computer press

about the exploits of the Black Baron,' said [judge Jeremy Griggs] to the

defendant before sending Pile to the bighouse for 18 months. "'Those who

seek to wreak mindless havoc on one of the vital tools of our age cannot

expect lenient treatment.'"



In America, Dr. Alan Solomon - developer of the UK-based Solomon

Anti-virus Toolkit (S&S International), worked the news into a

presentation given by his firm at the Fall ComDex in Las Vegas, Nevada.

The following week, Graham Cluley - a colleague and employee of Solomon

at S&S, privately remarked on the Compuserve on-line service that the

severity of Pile's sentence surprised him.



The treatment of Pile, a 26-year old unemployed programmer, by the

English press was slightly reminiscent of the US media's portrayal of

Kevin Mitnick.  In America, Mitnick was attributed with almost

superhuman malevolence, dangerous enough to bring down the Internet or

break into military computers controlling NORAD.  For The Independent

Pile was the "most famous" of virus-writers and the "most dangerous"

of a small band of them working in England.  The Independent

exaggerated when adding further that Pile's SMEG virus programs

were "the two most sophisticated ever written." This was probably

surprising news even to the anti-virus software developers interviewed

for the Black Baron stories.



Pile's viruses had reached "criminal elements" working in Northern

Ireland, the US, and Germany, according to the Independent. The future

damage, "inevitable" and "incalculable."



The demonization and denunciation of Pile was unusually harsh in light

of the fact that prosecution witness Jim Bates commented to

Crypt Newsletter that UK authorities were uninterested in sending

officials to collect evidence on the SMEG viruses in the United

States because a guilty verdict had been arrived at by mid-1995

(Crypt Newsletters 32 - 33).



The Times echoed The Independent's hyperbole, maintaining Pile had

written a "training manual" for virus-writers found "in America and

Northern Ireland where it was being used by criminals."



Ali Rafati, as part of Pile's legal defense, said his client was a

"sad recluse."  The real Pile is difficult to describe in any detail

even though an excessively overwrought and lugubrious "Biography of a

virus-writer" was written about him and circulated widely in the

computer virus underground.



As bombastic and pompous as anything written by The Independent,

Black Baron's biography begins:



"In 1969 Neil Armstrong stepped onto the moon. It was a momentous

year for the world. But no-one [sic] at the time paid much attention to

a baby boy being born in a town in southern England. This baby boy

was destined to grow into one of the most infamous computer virus

writers of all time. In 1969 The Black Baron was born!"



Curiously, almost 80 percent of the Black Baron's "biography" is a

reprint of material written by Ross M. Greenberg, a semi-retired

programmer who wrote the Flu_Shot and VirexPC sets of anti-virus

software. The reprint dates from 1988 and contains rather

standard anti-virus rant and rave, calling virus-writers "worms." This,

if the Black Baron's biography is taken at face value, formed the

basis of Pile's desire to write viruses and impress people with them.



Black Baron's biography reads (errors reprinted), ". . . when computers

stop attracting social inadequates, but whom I am refering to the

arrogant members of the anti-virus lobby as well as the nefarious virus

authors. But what of the Black Baron? What is he? Is he a malicious

criminal? A computer terrorist? A social inadequate trying to

reassure himself of his own inadequacies through destroying computer

data? I don't [believe] so. I have spoken to Black Baron on a number of

occassions. He is happy to discuss his work, and, at my request, he has

even released a document detailing the design of SMEG. He doesn't feed

on the panic and fear that SMEG viruses such as Pathogen and Queeg cause.

Rather he revels in the embarrasement and panic which his software causes

the arrogant anti-virus writers."



At the time, Pile was unemployed. The "biography" concludes:



"After talking with him, I understand the Black Baron. I feel sorry for

him as well. He is a highly gifted individual who has not been given a

chance by computer society. So he has made his own chance. We all need

recognition. Mainly through employment, but we as thinking machines must

receive recognition for our abilities. Otherwise we sink into melancholy

and paranoida. Black Baron has received his recognition. We, the

computer society are responsible for the creation of Pathogen, Queeg,

SMEG and all the other computer viruses. We have no one to blame but

ourselves. It is our desire to keep the computer fraternity a closed

club which has alienated so many of our colleagues. By rubbing their

noses in it, so to speak, we have begged for trouble, and like the

inhabitants of Troy, we have received it."



In retrospect, the underground remains of Chris Pile's cyberpersona

have become an even more cryptic, sad counterpoint to his stay in

an English gaol.



Pile's representation was contacted repeatedly by Crypt Newsletter

but, surprisingly, lacked e-mail addresses and could not be reached 

for concluding opinion.





ARF ANTI-VIRUS: THE SYSTEM SHIELD THAT IS NOT A DOG



The ARF anti-virus program is a set of software shields designed

to block virus infection and enable easy recovery of executable program

and system area code on a disk beset by computer virus. Its linchpin

is a module called ARFMAIN which is a memory resident behavior blocker.



Virus activity blockers aren't new.  ARF's authors, Stephen Poole and 

Leonard Gragson - a team in Kansas and North Carolina linked by the 

nature of cyberspace, admit this and state they've gone to some length 

to minimize the knocks leveled against this type of protection: prone 

to false alarms, not air-tight, saps system resources.  The pro's and 

con's of the approach of fine-tuning virus blocking software until 

the drawbacks don't exist have been trotted out and argued repetitively 

over the years by the multitude of software vendors. 

Central Point/Microsoft Anti-virus's VSAFE, for instance, was

elementary to use and install but so porous it was very little 

insurance against computer viruses.  Robert Hoerner's Nemesis, a

German product, was so paranoid and restrictive no virus could operate

against it. Indeed, some virus writers, most notably Germans who

envisioned their creations running into Nemesis, wrote their programs

to test for the presence of the software and just quit if it was around.

However, Nemesis also tended to be rather airtight to normal use of 

the PC.



The ARF virus blocker is one of the best behaved device drivers of

this nature Crypt has worked with.  Purely incidentally, it is

similar in look and feel to Trend Microdevice's PCRx so users

familiar with that software will be comfortable with it.  Alone,

the ARF driver makes it impossible for most types of viruses to

act on a system without generating numerous trapping and warning 

messages which allow the user to get in front of infections.  The

warnings are delivered with varying amounts of information and

a suggested response dependent upon the severity of the problem.

As implied, its false alarm rate is minimal and when acting as a

safety-net in the background its presence is largely imperceptible.



One of the ARF driver's best selling points is its efficient disposal 

of partition sector and boot-sector infecting computer viruses.



The ARF driver knows the ROM address of the Interrupt 13h hard disk

for a secured machine and, as a consequence, can easily remove these

types of viruses in most instances even when they taken control

long before the ARF driver.  This means that if the PC is booted from 

an infected diskette and the partition of the hard disk contaminated, 

the ARF driver will load on restart, warn the user the disk has been 

infected and offer to restore the system. Viruses like Monkey, AntiEXE, 

Russian Flag, Urkel, Stealth Boot C, Stoned variants, Sampo and 

Leandro & Kelly could all be removed with a keystroke on testing.  

The machine is halted when the virus is purged.



Alert readers may remember a recent Crypt Newsletter article that

out-lined some weird gymnastics Quantum and Symantec were going through

to come up with a hardware and software-based anti-virus solution that

did just this very thing, only badly.  Programs like ARF show the

discerning that large companies with extensive R&D budgets are not

necessarily immune to stupidity in design and that smaller firms often

can and do figure out superior solutions.



The ARF driver is also compatible with anti-virus scanning software.



Crypt Newsletter knows how to select weird computer viruses under

extreme conditions to poke holes in just about any anti-virus software

and ARF is no exception, however, without going into a lot of needless

detail it's accurate to say the software is extremely robust against

the vast majority of computer viruses in circulation.  ARF trips up

most viruses that do fancy things in memory by being acutely sensitive

to attempts to trace or exploit unusual or poorly documented aspects of

the operating system kernel, aspects often used by computer viruses.

In most cases, such viruses produce immediate warnings or simply result 

in the ARF driver hanging the system.  Nightfall, a subtly transparent 

.COM/.EXE infector that does some slippery things in computer memory, was 

one exception.  A virus written precisely like Nightfall could, 

theoretically, execute directly past the ARF driver, infect the command 

shell and run without generating a peep from the software.  It should be 

noted that Nightfall can do this with almost every other anti-virus 

software on the market, too, if not detected by scanning.  Paradoxically, 

Nightfall is one of the German computer viruses that simply surrenders 

and goes dormant against the Nemesis virus blocker.



The ARF driver is meant to run in conjunction with a PC treated

by an ARF utility, called INJECT, which encapsulates executable

programs in a code fragment that confers self-recognition and

auto-restoration capability to protected programs.  Many anti-virus

software developers consider this heresy but the ARF authors have

gone their own way and generated something which works quite well,

anyway.  ARF-protected programs will restore themselves after

most virus infections. The protection is much stronger when the

ARF driver is present although still quite functional when forced to

stand alone. There are a couple caveats:  A virus exactly

like Nightfall can infect ARF-protected programs without generating

alarms since the virus, from the standpoint of the INJECT-ed program

is invisible, effacing itself from the executable prior to self-check

and re-infecting the target on exit.  Quite a number of "stealth viruses"

try to do this type of thing and are prevented from being

successful against an ARF-protected machine by the presence of the

device driver virus block.  Simply, they just can't get going

enough to infect any meaningful number of programs before the

software halts the system.



ARF-encapsulated programs are not proof against overwriting

viruses or simple software boobytraps that totally corrupt programs or

the disk.  Nothing is. However, if the ARF suite is installed

properly - not piecemeal - none of these types of computer hotfoots

can execute even once without being trapped unless they're quite

sophisticated or write to the hardware directly. This would be

extremely unusual.



Since the ARF INJECT utility modifies executable code on your disk,

using it in a test run or full installation will cause other anti-virus

programs that analyze your PC for changes to programs to pop a nut.  This

is another good example of why it's excessively dumb to mix and match

anti-virus programs willy-nilly if you have no idea what you're doing.



The ARF anti-virus programs also create a "magic diskette" for when

the machine won't boot from the hard disk or if the device driver

needs a helping hand.  The diskette is assembled so it

contains vital data on the system area of the machine and a

unique identifier for the PC it was made from.  The ARF software

renders it unreadable by DOS as insurance against intemperate

meddling.  The ARF rescue disk is made so its restore feature is

loaded directly from the diskette's boot sector.  This means it will

get a head start on just about anything save a complete hardware

meltdown on a disabled PC. The ARF disk offers a number of options

including restoration of the hard disk's damaged or corrupted partition

sector and is absolute insurance against the "cursed disk" fault mentioned

previously in this issue.  This ARF utility also offers an option

to create a special partition sector for a secured machine but

the protection is not critical for the overall performance of the

software.



Those users yearning for anti-virus scanning software to wave

obsessively like a magic wand at suspicious programs and diskettes

could be uncomfortable with the ARF programs.  ARF is also potentially

troubling to users whose level of expertise is exceeded by anything

beyond the stabbing of the America On-Line button. Anyone else will get 

excellent service and would be well-advised to give ARF a look.

lucky, in 1996 Mr. Markoff could make you CyberPublic Enemy Number 1

LONELY SINGAPORE NATIVE LOOKS FOR SIGNS OF LIFE

===============================================



Dear Crypt:



Can you please tell me where to get the Biological Warfare

computer virus creation kit?



I am a curious thrill-seeker who is still a student.  The

information from Biological Warfare will help me do a program

I am researching.  My plan is to make a program that will encrypt

and add polymorphic power to a normal .EXE or .COM-file in order to

prevent hackers from getting into it.



Anyway, I like viruses, because I think they are "cute" in the sense

that they seem so much like little animals.  They reproduce, they

"eat" and sometimes destroy.  In fact, if you imagine the computer

as a "desert," viruses can be wild animals while anti-virus programs

could be hunters.



Squane in Singapore



[Crypt replies: Dear Squane, you can't get this kind of information from

Bio Warfare. It's a virus-making kit, not an artificial life

generator or a Philosopher's Stone. As for encrypting programs as a

barrier to reverse-engineering, you might consider digging up for

examination some programs that already offer this service: Jeremy

Lilley's Protexcm and Tranzoa's TinyProg come to mind.  Crypt Newsletter

19 also included a couple of simple, easily used examples that performed

roughly the same thing. They were not foolproof, state-of-the-art or

impenetrable, but they were easily understandable.  You should recognize

that polymorphic encryption as practiced by virus writers isn't tough to

crack from the standpoint of a cryptographer or a software disassembler.

It's only utility is that it renders brute force simple bitstream

scanning of computer viruses encrypted in this manner impractical to

impossible.  From a cryptologic standpoint, however, I would think

polymorphism is uninteresting.



Keep in mind there are also a number of people who've made it their

business to program reverse protection software utilities solely to

peel off the types of code armoring you're interested in. And it seems

to Crypt they have the edge.



As for viruses being "cute," for God's sake, man, get a grip on yourself

before it's too late!  Thrust yourself away from the PC for a minute

and pour yourself a stiff drink. Out of concern for your mental

health, Crypt has forwarded your message to the Singapore Department

of Corrections and Caning.  I know they'll put you in good hands.]

MORE ANKLE-BITING

=================



To Whom It May Concern:



I recently downloaded the Virus Creation Laboratory from the Usenet. I

already have the virus making kit, the NuKE Randomic Life Generator, but

decided I would give VCL a shot, too. Actually, I'm pretty sick of typing

out all the assembly code for viruses myself. I don't see why I should

spend a week or two working on a new computer virus when I could create

one much easier with VCL! What's technology for, anyway? However, when

I tried installing it I came across a problem. The software unzipped

from its archive OK but when I tried running the program it issued an

error message that VCL could only be used on the original computer it was

installed upon. This was the first time I executed VCL so how can it not

be the original? Is this archive simply a repackaged copy from a prior

installation or something? Jeezus.



Thankx.

source code?  I would DEEPLY appreciate it.

A PUZZLED JOURNALIST REQUESTS RESEARCH ASSISTANCE, ANSWERS TO BURNING

QUESTIONS

=====================================================================



Hello Crypt Newsletter:



I am working on an report concerning the dangers of electronic

database crossovers and the security implications for each of us. I

am looking for some ideas to present hacking as a way to create an

opposite, balancing power to the "masters of the electronic world,"

sort of like Sandra Bullock in the movie, "The Net."



Thierry Maillet: CIS





[Crypt replies: Before we get started on this I want to bring

something to your attention that, perhaps, has a more local angle for

you. I was just exchanging mail with a fellow by the name of JeanBernard

Condat in response to a small that appeared in Crypt Newsletter 34.

JeanBernard, whose reputation is that of one of the most famous French

hackers, was apparently an agent of a French surveillance agency.  It's

my understanding he was turned while a student, was pressed into

service as a front and report writer on hacker activities, and eventually

broke away after a number of years of this type of thing.



Now while my grasp of the events are very incomplete, it seems to me

that it immediately throws into serious question whether hackers can

monolithically be presented in the way you're aiming. If

you grab a copy of the Jonathan Littman's book, "The Fugitive Game,"

you'll quickly read that "hacker" Justin Petersen (better known as

Agent Steal) while an FBI informant, was a pure-and-simple

menace to the privacy, bank accounts and mental health of just about

everyone and anyone he could screw: other hackers, girlfriends, complete

strangers, his law enforcement handlers.



Obviously, if you're going to bother to take the time to do a

comprehensive report, you will have to look at these issues in a

discerning manner.



Some of the best examples I can give you, and I'll make this

brief, are in my book, "The Virus Creation Labs."  There are

many instances of hacker profiles in it and the picture that emerges

is complex, not at all like a Hollywood fantasy in which rebel computer

gurus act as counterbalances to corporate and institutionalized power.]





EURO COLLEGE STUDENT ASPIRES TO WRITE BOOK ON COMPUTER VIRUSES

==============================================================



Dear Crypt:



Why doesn't the Crypt Newsletter deal with virus-programming techniques

anymore? I'm planning to write a book about virus-programming

technics [sic]. That's why I am looking for virus source codes.



I'm attending the Eotvos Lorand University of Science in Budapest,

Hungary.



Szabin Szoke, Budapest





[Crypt replies: That's t-e-c-h-n-i-q-u-e-s, Szabin,  not "technics."

Writing a book, eh? If Crypt received one thin dime for every

anonymous clown who sent this line . . . but, to your question.



I haven't made any effort to make virus source code available in the

last two years of issues for a number of reasons, a couple of which I'll

mention. First, computer virus retrieval on the Internet is trivial

business. It's easy to come by hundreds, even thousands, of the programs.

And since my favorite parts of the Crypt Newsletter weren't devoted to

virus source code in the first place there was little harm to my

enjoyment of the magazine in ditching the material.  Other e-zines on

the Internet still do publish virus code and their editors are lot more

enamored of the idea than I am, so they're the people to patronize.



In addition, it's all been done.  The technology of computer viruses for

the Intel platform is extremely prosaic.  If you're unfamiliar with the

subject, it may seem exotic but . . . it's not. There are also some books

on computer viruses one can purchase. One is reviewed in the this issue.

(I admit it's pretty shabby, but it might be something that floats your

boat.) Or, you can acquire virus collections, complete CD-ROMs of

computer viruses.  If you must have computer viruses, whether you want

them as resources for a book, objects of idle curiosity, trivial

start-ups to anti-virus work or quite some other thing, and you're so

inhibited you can't strike out on the info highway and find some - this

is one route that can be travelled. Don't be a dilettante.



Computer viruses also restricted the audience of the newsletter making

it _too_ much a specialty publication.  Crypt News is still specialized,

but anti-virus researchers and virus-writers were a very narrow

demographic. As an extremely eccentric, inbred and highly secretive

subculture of propeller-heads, a great many of whom you'd be embarrassed

to be seen in civilized company with, they make for excellent subject

material but an awful sole readership.]





LONG-TIME CRYPT READER OFFENDED BY SANDRA BULLOCK AS VIRTUAL

SYMBOL OF CYBERSPACE CITIZEN, AFFLICTED BY BRAIN FLUKE WHILE

WATCHING EVENING NEWS, BREAKS RECORD FOR NUMBER OF HYPHENS IN LETTER

TO EDITOR

============================================================



Dear Crypt:



I'll get right to the point:  Howdy-dooty, howya doin'????



I saw - but didn't really want to expend any of my remaining

limited and non-renewable mental resources on reading -  the reference

to the K-HiP MoOViE "ThE NeT," starring Sandra Cyber-Bullock.  I do

not wish to see this flick!  I doubt I could handle it, especially

in my weakened condition.  You see, I accidentally exposed myself - er,

you know what I mean - to nearly 6.3 seconds of evening network news

hosted by Tom Brokaw before I realized what was happening.



In a rush to cancel the offending broadcast, I accidentally

flipped over to C-SPAN and was further exposed to approximately 2.1

seconds of Dianne Feinstein blathering on about one thing or

another in her New World Order Lite(tm) sterile corporate

I-Know-Better-Than-You-What's-Good-For-You-And-Besides-My-[Word Effaced

by Crypt Corporate Standards & Practices]-Bigger-Than-Hillary's

monotone.



Unfortunately, the doctors say that some of the damage is probably

irreversible.  Their diagnosis also told me that if I had encountered

any footage of flag-and-bunting-encrusted Republicans or

giant-inflexible-pompadour-sporting televangelists, I might very well

not have survived.



I'm not certain whether I got the good end of the bargain.

If you quite enjoy the Crypt Newsletter, editor George Smith's book,

The Virus Creation Labs: A Journey Into the Underground,"  will

really flip your wig. In it Smith unravels the intrigue behind

virus writers and their scourges, the anti-virus software

developers and security consultants on the information highway.



What people are saying about THE VIRUS CREATION LABS:



     "I couldn't stop reading it . . . As hype continues to

     build about security on the Internet and movies like

     _Hackers_ ooze the real hackers into the mainstream arena,

     this book is definite apropos material for the time.

     Read it! A+"

                      ---The Net magazine, February 1996

     

     

     "[VIRUS CREATION LABS] is informative and stunningly

     incisive . . . "

                      ---Secure Computing, October 1995



     "George Smith . . . takes a look at the world of virus writers

     and anti-virus software vendors in a style similar to that

     of 'Cyberpunks' -- anecdotal, humorous and revealing . . . a

     lucid and entertaining read."



                      ---Computer Security Journal





     "There are relatively few books on the 'computer underground' that

     provide richly descriptive commentary and analysis of personalities

     and culture that simultaneously grab the reader with entertaining

     prose. Among the classics are Cliff Stoll's 'The Cuckoo's Egg,'

     Katie Hafner and John Markoff's 'Cyberpunk,' and Bruce

     Sterling's 'The Hacker Crackdown.'  Add George Smith's

     'The Virus Creation Labs' to the list . . . 'Virus Creation

     Labs' is about viruses as M*A*S*H is about war!"

                       Digest 7.18, March 5, 1995



     "THE VIRUS CREATION LABS dives into the hoopla of the Michelangelo

     media blitz and moves on to become an engaging, articulate,

     wildly angry diatribe on the world of computer virus writers . . .
