"The Xenix Chainsaw Massacre" Is A Very Dangerous Document ------------------------------------------------------------------- It is reputed among many of the top minds in the Computer Industry to be a very real, and revealing, documentary of some of the horrors of the Industry which are sometimes rumored, but seldom exposed. But be warned-they say it in private, not in public. Though management at the major Corporations in the Industry brush aside the document as the mad ramblings of an unstable, failed business executive, the fact remains that there are more and more people coming forward who claim to have suffered demotions or loss of employment after deliberately or inadvertently revealing their support of the document's claims and it's authenticity. If you choose to read this manuscript, do not speak of it in casual conversation at your place of employment, or around strangers in any business or social environment. Though it is almost impossible to document cases of reprisal of this nature, the increasing numbers of ex-employees of major Corporations in the Computer Industry making these claims, and the devastating consequences they allege to their professional and private lives, make it wise to be discreet in expressing any opinion, or even knowledge, of this document. If you choose to share this document with others, it would be wise to do so discreetly, even anonymously, should you be unsure of the reliability and discretion of whomever you choose to share this knowledge with. Though I personally lean toward viewing the manuscript as authentic, my exhaustive research into it's origin has always come to a dead-end, even among the principals involved. C.J. Parker, former President of Pearl Harbor Computers, Inc., denied emphatically, in a face-to-face encounter with anything whatsoever to do with the document. When I pressed him with questions regarding the hasty demise of his business and the unraveling of his personal life after the public circulation of "The Xenix Chainsaw Massacre" began, he became very agitated and distraught, bordering on violence, and the interview was abruptly terminated. Dr. William M. Denney, one of the few principals in the manuscript referred to directly, was reluctant to be interviewed, but eventually made a few comments which I found to be very revealing. Dr. Denney, Vice-President of Basis, Inc. in Emmeryville, Ca., consistently rated as one of the top ten Unix Open Systems vendors in the world, said, "I deny any knowledge of or participation, in any way whatsoever, with anything connected to 'The Xenix Chainsaw Massacre', and it would be wise for others to do the same." I find this statement to be very cryptic and, at the same time, very revealing; very much in line with what would expect from one associated with the alleged underground computer society described in the manuscript. As for Mr. Torry Basford, a former employee of Bell Labs who was Mr. Parker's first mentor in the world of Unix and is rumored to be laboring in obscurity in a small community college somewhere in the southwestern U.S., Mr. Parker would only say, "The man has suffered enough, please leave him alone." Regardless of the origins or authenticity of the document, it is considered by many to be extremely unsettling, perhaps even dangerous, and one might be better served to avoid reading the manuscript, if for no other reason than simple peace of mind. ___________________________________ If you would like a copy of the manuscript, send me a private email indicating a desire to receive it.

But, if Jim writes the bot well, puts it in an unknown place (remember, all communications are done through remailers), he could die, but the assassination bot would still work. It may be an interesting problem: what steps are necessary to take to provide for the bot maintainers' sudden death in such a way that the bot would survive for a long time (at least 10 years) w/o any maintenance? Several things need to be done, such as running several versions of the bot so that they could all communicate and work as hot standbys in case one of the instances stops communicating; change their anonymous address from time to time to deal with shut down remailers; probably slowly propagate as virii, so that killing them all would be hard; what else? It could be done akin to Thompson's famous backdoor in /bin/login, as a perpetual trojan horse. How to prevent the bot's detection by sysadmins? - Igor.

Recovery of Windows NT administrator password
by Garrard 17 Dec '03

17 Dec '03

An inherited Windows NT system that I am involved with has a lost administrator password ( no one no longer knows what it is ). Can anyone point me to software products/companies that can help in the recovery. Given Microsoft's dismal record on security I am sure there must be solutions to this dilemma. Any help would be greatly appreciated. Best Regards David L. Garrard

Physical meet, Sat. Feb. 15 - not 18.
by Jim Choate 17 Dec '03

17 Dec '03

Hi all, I apparently didn't pay much attention to what month I was looking at when I made the initial meeting. Turns out the 18th is a Tuesday obviously a day that few of us can make. As a result I looked at the 'real' Feb. calendar and the meeting date is as follows: Saturday, Feb. 15, 1997 6pm. HEB Central Market Restaurant Look for the red 2nd. ed. Applied Cryptography book For more info email 'austin-cpunks(a)ssz.com' Also invited to this meet are members of the mailing lists: Experimental Science Instrumentation Advanced Computer Experimentation Sorry for the confusion.

I was denied admission to MIT even thought I had a 3.82 GPA, 1440 SAT (one try), and had taken 9 AP tests with two 5's, four 4's, two 3's, and one 2.

MIT is one the best schools in the country for C.S. Close behind is Carnegie Mellon University (C.M.U.) in Pittsburgh, PA. (the folks who put out CERT.) Not sure how much Crypto they do, though.

Re: Machine readable form (was:RE: [DES] DES Key Recovery Project, Progress Report #7)
by Phil Karn 17 Dec '03

Read the following text from the introduction to the new December 30, 1996 regulations: A printed book or other printed material setting forth encryption source code is not itself subject to the EAR (see Sec. 734.3(b)(2)). However, notwithstanding Sec. 734.3(b)(2), encryption source code in electronic form or media (e.g., computer diskette or CD ROM) remains subject to the EAR (see Sec. 734.3(b)(3)). The administration continues to review whether and to what extent scannable encryption source or object code in printed form should be subject to the EAR and reserves the option to impose export controls on such software for national security and foreign policy reasons. This seems clear enough. If it's printed on paper, it's kosher for export. But if we're really overt about it, we may goad the government into attempting to control printed source code as well. That could prove most interesting. Phil

Last nail for US crypto export policy?
by Ian Goldberg 17 Dec '03

17 Dec '03

EXPORTABLE CRYPTOGRAPHY TOTALLY INSECURE: CHALLENGE CIPHER BROKEN IMMEDIATELY January 28, 1997 - Ian Goldberg, a UC Berkeley graduate student, announced today that he had successfully cracked RSA Data Security Inc.'s 40-bit challenge cipher in just under 3.5 hours. RSA challenged scientists to break their encryption technology, offering a $1000 award for breaking the weakest version of the code. Their offering was designed to stimulate research and practical experience with the security of today's codes. The number of bits in a cipher is an indication of the maximum level of security the cipher can provide. Each additional bit doubles the potential security level of the cipher. A recent panel of experts recommended using 90-bit ciphers, and 128-bit ciphers are commonly used throughout the world, but US government regulations restrict exportable US products to a mere 40 bits. Goldberg's announcement, which came just three and a half hours after RSA started their contest, provides very strong evidence that 40-bit ciphers are totally unsuitable for practical security. "This is the final proof of what we've known for years: 40-bit encryption technology is obsolete," Goldberg said. The US export restrictions have limited the deployment of technology that could greatly strengthen security on the Internet, often affecting both foreign and domestic users. "We know how to build strong encryption; the government just won't let us deploy it. We need strong encryption to uphold privacy, maintain security, and support commerce on the Internet -- these export restrictions on cryptography must be lifted," Goldberg explained. Fittingly, when Goldberg finally unscrambled the challenge message, it read: "This is why you should use a longer key." Goldberg used UC Berkeley's Network of Workstations (known as the NOW) to harness the computational resources of about 250 idle machines. This allowed him to test 100 billion possible "keys" per hour -- analogous to safecracking by trying every possible combination at high speed. This amount of computing power is available with little overhead cost to students and employees at many large educational institutions and corporations. Goldberg is a founding member of the ISAAC computer security research group at UC Berkeley. In the Fall of 1995, the ISAAC group made headlines by revealing a major security flaw in Netscape's web browser.

Crypto verification needed for Pretty Safe Mail
by Anonymous 17 Dec '03

17 Dec '03

There have been questions raised on the newsgroups regarding Pretty Safe Mail, arguably the best implementation of a PGP product for the Macintosh. In response, the product manager at Highware has requested that a trusted third party verify the security of Pretty Safe Mail. However, a NON-U.S. cryptologer is needed. I'm including the post below. Please forward to any people you know who may qualify. Pretty Safe Mail is a GREAT product. If it can be shown to be safe and effective, it will do wonders to spread the use of strong crypto. ===== From: axel(a)highware.com (Axel de Landtsheer) Newsgroups: comp.security.pgp.discuss Subject: Re: Concerned about Pretty Safe Mail for Mac > I'm concerned about the product "Pretty Safe Mail" for the Macintosh, >by a company called Highware. I was wondering whether anyone here had >tried evaluating it at all. > > It is a complete PGP implementation (not a front-end). They claim >to have licensed some of PRZ's code from PGP. However, as far as I >can tell, they are not making any of the source code available. The source code for PSM is indeed not available. We are however eager to have the code checked by any trusted source. These sources cannot be US companies because of the new US regulations which state that US companies must not give such support to overseas companies. Us being a Belgian company, this makes things a little more difficult. Does anybody have a suggestion for such a trusted source outside the US? > As someone on the comp.security.pgp newsgroups pointed out, writing >a wonderful user interface on a PGP trojan horse that either crippled >the session key generator or used the session key to leak random >portions of secret key primes would be a perfect tactic for a >government wishing to penetrate PGP security.

Does any trusted source want to check that? > I realize that without the source code, it's a major hassle, but >has anyone looked at Pretty Safe Mail (previously called Safemail) >at all for suspicious behavior? For example: > > 1) non-random session key generation? > 2) non-random key pair generation? > 3) unnecessary disk access to secret keys? > 4) anything else? Many people are worried about the random-key generation because they do not need to bang away on the keyboard for five minutes when they create a key pair. Apparently, this seems to loosen their nerves (I heard some people created about 10 key pairs a day - just a joke). In short, we use all events that happen on the Mac (clicks, typing, opening of windows, display of icons, ...) together with the time they happen, and encrypt these to fill a table which is the starting point for the random-number generator. Why make people type away on the keyboard if you have enough random events to start from? Again, we want to have this checked by a trusted source asap... ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Axel de Landtsheer | Highware, Inc. | 109 av. H.
