ViaCrypt Fires Tim C. May
by ViaCrypt FiringBot 17 Dec '03

17 Dec '03

From: ViaCrypt FiringBot To: Tim C. May Dear Ms. May, We regret to inform you that your employment with ViaCrypt has been terminated, effectively immediately. In accordance with company policy we will outline the reasons for your termination below. 1. Records from your company supplied E-ZPass electronic toll booth pass indicate that you are arriving in the city over an hour before you begin work, leading us to believe that you are engaged in personal activities during this time which take away from the energy you have left to put into your company work. 2. The OnStar satellite-positioning service reports that your company supplied Cadillac was parked at the restaurant where you ate with your company supplied Visa card for an hour and ten minutes. Employees are only allowed one hour for lunch breaks. 3. The Teletrac global-positioning satellite has reported that you exceeded the speed limit twice in one day (32 mph in a 30 mph zone, and 56 mph in a 55 mph zone). 4. The passive tracking microchip on your company supplied ID card was tracked by our remote sensors in six parts of the city which we prefer that our employees not enter. 5. Your company supplied cellular phone was used to call someone not in our business database who used his MasterCard to buy condoms at a local pharmacy during a weekend when his wife used her Visa to take a trip out of town. This reflects badly on the company. 6. The company aerial drone reports that in several passes over your home, the presence of marihuana smoke was detected. 7. Surveillance of your company email indicates that you have been using company resources to include private messages such as "Have a nice day." in business email sent on company time. 8. Reports sent in to the company by the automatic modem software on your company supplied laptop indicate that you have visited websites which are not approved by CyberSitter, such as the City of SEXton community website. 9. Video surveillance of the Men's Restroom indicates that you have been wasting company resources by using more toilet paper than necessary, in relation to the amount of human waste monitored during your visits. Also, you twice failed to put the toilet seat down, as required by our company policy of sexual sensitivity. 10. Our monitoring of your user access to the company computer system shows that you accessed areas of the system which were not found to be in accordance with your security level. Our records indicate that ViaCrypt owes you $15,000,000.00 for your 1 day(s) of employment. This has been deposited in your Bank Account in Antigua, according to your wishes. Sincerely, (as sincere as a machine can be, that is) ViaCrypt FiringBot

I don't have any problem with the feature, only with the use of the PGP reputation capital to directly promote it. If they wanted to call it 'Pretty Corporate Privacy' then the name would reflect its purpose. Security, in regard to privacy, is an all-or-nothing issue. As such, I do not find it acceptable to apply the same standards of promotion and dissemination as with less important types of software. The fact of the matter is, the product has nothing to do with the privacy of the individual using it, only the privacy of the corporation. This is an important distincion which should not be subject to confusion with a product by the same name which is noted for providing a secure level of privacy for the individual. I would wager that promoting a false sense of security, or an incorrect view of the levels of security and trust involved in company software will do more damage than the occassional loss of keys will. Again, the product does not provide 'Pretty Good Privacy,' it does provide 'Pretty Corporate Privacy.' PrivacyMonger

Trademarking CypherSpace???
by Bill Stewart 17 Dec '03

17 Dec '03

Sigh. A company called I-Planet is trying to trademark the term "Cypherspace", even though we've been using it for a couple of years in the cypherpunk community. They're doing an IPSEC Virtual Private Network, with friendly HTML administration; http://www.i-planet.com/P2cypherpb.html . Looks like interesting stuff, and I wish them luck except in TMing the name :-) I looked on AltaVista and HotBot, and the earliest reference I found was from a 1994 article by Tim May. I'd be interested in finding any earlier refs. There's also a line of comic books using the name, and a Java Applet from 1996, plus references from I-Planet in late 96 and 97. Anybody know if the term's been used in print in the dead-tree press? http://www-swiss.ai.mit.edu/6095/assorted-short-pieces/may-police-state.txt 05-Oct-94 http://www.pi.net/~mvheezik/cypher.html 20-Dec-96 http://infinity.nus.sg/cypherpunks/dir.archive-96.10.17-96.10.23/subject.ht… pointing to David Lesher's article Alice in Cypherspace http://www.insitecomp.com/webdev/java/javasites.htm 7-Dec-96 points to "Cypherspace", a Java Application on a machine I don't seem to be able to reach right now. ============================================================= ==== FROM http://www2.netcom.com/netcom/cypher.html and also ==== http://www.i-planet.com/P2cypherpb.html ======== Introducing i-Planet's CypherSpace As part of the i-Planet Solution product family, CypherSpace allows a company to securely link all of its locations together over the Internet by creating a Virtual Private Network (VPN).

Risks of using usually-reliable information sources in your programs
by Bill Stewart 17 Dec '03

17 Dec '03

I've been thinking about building remailers and cover-traffic generators, and there's a need for a convenient up-to-date list of remailers. Raph Levien's remailer pinging service is definitely convenient, and even produces some of its output in perl for use by perl programs. However, it's important to be really careful when depending on information like this, e.g. when building it into programs, because otherwise it's easy to trick them into using bogus data, such as the crudely forged article sent to Cypherpunks earlier today. The natural implementation is to pick the more reliable remailers based on "Raph"'s statistics, so adding records for very reliable bogus remailers is a win. The security would be improved if Raph signed the weekly file, but that also requires people using the file to check it with PGP and not just grep out the relevant lines for their programs' use. >X-Sender: stewarts(a)popd.ix.netcom.com >X-Mailer: QUALCOMM Windows Eudora Light Version 3.0.3 (32) >Date: Sun, 05 Oct 1997 18:06:56 -0700 >To: cypherpunks(a)toad.com >From: Raph Levien <raph(a)CS.Berkeley.EDU> >Subject: List of reliable remailers >Sender: owner-cypherpunks(a)cyberpass.net >Reply-To: Raph Levien <raph(a)CS.Berkeley.EDU> >X-Loop: cypherpunks(a)cyberpass.net > >-----BEGIN PGP SIGNED MESSAGE----- >Hash: SHA1 > >ADVERTISEMENT: Proudly Sponsored by the Electronic Forgery Foundation, >http://www.eff.com >ADVERTISEMENT: Digicash Software - Download Today! http://www.digicrime.com > > I operate a remailer pinging service which collects detailed >information about remailer features and reliability. .... >recovery remailer(a)biglouie.fbi.gov ############ 0:01 99.99% >payswell remailer(a)digicrime.com ############ 0:01 99.99% >trustme trustme(a)trustme.nsa.mil ************ 0:59 99.99% >mulder mulder(a)juno.com #*#*##*#*#*# 0:57 99.98% Thanks!

Three words: "Expectation of Privacy." Unicorn, In that piece of knowledge smashing, just as you do in most of your posts, you again mixed up things to make sure that everybody end up knowing less than when they started. It is peoples like you that ended up with using Expectation of Privacy out of it's rightfull context. Apart from various rulings of various judges that probably smoked various herbs, can you please tell me how anybody can rightfully expect privacy when everything that permits them to exchange information is *owned* by somebody else and that the use of this equipment is there *only* for the activities of the owner of the equipment? If it weren't of the business, the damn computer wouldn't be there. And beside, the employee is not paid to chat with friends, he's paid to work. If he doesn't want to work, just fine, but not on the company's pay... Somehow, you basic premises always blows my mind. I think that you are a *very* dangerous person. I've been watching you for almost three years over Cypherpunks and e$-etc and other forums. Virtually *all* of your posts have this blow-up-their-basic-premises-and-let-them-with-nothing-but-confusion style. Your style shows intelligence and skill in the way you do it, which rules out idiocy on your part. So, clearly, you have an agenda. I cannot help but having the nagging feeling that you're on some three-letter agency payroll because you have the uncanny habit of disrupting and diverting some important discussion. I always wanted to killfile you but always refrained to do so just to be able to read the last finely crafted basic premises-smashing abomination. So, again, which of the three-letter agency sends you a paycheck? Or are you doing is only for a secret decoration? jfa -- Jean-Francois Avon, Pierrefonds(Montreal) QC Canada DePompadour, Societe d'Importation Ltee Finest of Limoges porcelain and crystal JFA Technologies, R&D consultants physicists and engineers, LabView programing.

An AltaVista search for "cypherspace" pulls up a Tim May rant on The Coming Police State dated 9 Mar 1994 on the topic, so it's at least 3.5 yrs old. Good historical reading, by the way... dates back to the Clipper era. Don't you hate it when the pessimists are right all the time? Jim Gillogly

Absolutely. > God you frighten me. Unicorn, as usual, you twist words like nobody but you (and a zillions politicians) can. You forget the fact that the association between a company and an individual is voluntary. As long as all the tests and surveillance done by the company is known by the employee, it can do anything it wants. Only, you are also free to find another employer. And in the old days of paper correspondence, what prevented a company to give five years of a given employee's correspondence to the FBI? As a business owner, I wouldn't put cameras in the bathrooms, but I would certainly *require* that an encrypting software be decypherable by the top management. Encryption is an envelope. Sometimes, it is justified that management open suspicious enveloppes. As long as a behaviour doesn't impair work performance, there is no reason to pick on it. And personnally, I'd maybe keep somebody with impaired work capabilities but negociate a pay reduction instead of firing him/her. He is free to find work somewhere. This is *NOT* coercion. Your thing about the cops having access to info is an entirely different story. If the company doesn't have the balls or the strenght to resist bullish tactics, then, it is their problems. The employee should simply have evaluated earlier if the company would sell him out to the first spook and choose to work for somebody else. What you seemed to imply when you wrote that precisionless paragraph is that, in the end, key escrow by the owners of the company and computer system is dangerous. But to the company, not having the possibility to decrypt the data they *own* and are liable for is even more dangerous. The data generated on company's time and pay is property of the company. There is no coercion. Everybody is free to act, find another employee or keep him, find another job or keep it. Period. Ciao jfa P.S.

Three words: "Expectation of Privacy." I missed the original post, but here are my $0.02. I encrypt all outgoing encrypted work email to my own key as well. I would be just as happy to encrypt it to the corporate key. If I was to send some private email from work, something that is not frowned upon at my place of employment, I would simply pre-encrypt it with just the key of the recipient. Meanwhile, I can understand the desire of a company to be able to read old outgoing email even after the employee quit or forgot their passphrase. After all, it might contain valuable information about details surrounding past negotiations with clients. Information that I would not want to be without. And PGP's Policy Enforcer has another side to it: have you ever forgotten to encrypt email that should have been encrypted? I have. With the Policy Enforcer installed, that can't happen. Which may well save big hassles in the future. All IMHO, of course. --Lucky Green <shamrock(a)netcom.com> PGP encrypted mail preferred. DES is dead!
