Jay Rolls, Stuttgart, Germany [sent to RISKS by gio@DARPA.MIL (Gio Wiederhold) via many others] COMPUTER CHEATS TAKE CADSOFT'S BAIT Employees of IBM, Philips, the German federal interior ministry and the federal office for the protection of the constitution are among those who unwittingly 'turned themselves in' when a German computer software company resorted to an undercover strategy to find out who was using illegal copies of one of its programs. Hundreds of customers accepted Cadsoft's offer of a free demonstration program that, unknown to them, searched their computer hard disks for illegal copies. Where the search was successful, a message appeared on the monitor screen inviting the customer to print out and return a voucher for a free handbook of the latest version of the program. However, instead of a handbook the users received a letter from the Bavarian-based software company's lawyers. Since the demonstration program was distributed last June about 400 people have returned the voucher, which contained coded information about the type of computer and the version of the illegally copied Cadsoft program being used. Cadsoft is now seeking damages of at least DM6,000 (ECU3,06E2) each from the illegal users. Cadsoft's tactics are justified by manager Rudolf Hofer as a necessary defence against pirate copying. The company had experienced a 30% drop since 1991 in sales of its successful Eagle design program, which retails at DM2,998. In contrast, demand for a DM25 demo version, which Cadsoft offered with the handbook of the full version, had jumped, indicating that people were acquiring the program from other sources. Although Cadsoft devised its plan with the help of lawyers, doubts have been raised about the legal acceptability of this type of computer detective work. In the case of government offices there is concern about data protection and official secrets. The search program may also have had side-effects that caused other files to be damaged or lost. Cadsoft is therefore preparing itself for what could be a long legal battle with some customers. So far it has reached out-of-court agreement with only about a quarter of those who incriminated themselves. ------------------------------ Date: Thu, 21 Jan 93 10:59:25 PST From: shaun@octel.com (Chocolate Flavored Clorox) Subject: Educational computer game banned in Milpitas CA RISK in paragraph three. The following appeared in the _Milpitas Post_ Vol. 37 No. 2, January 13, 1993, of Milpitas, CA on page 1. Superior Court ruling upholds `Wizards' ban, by Christina Kirby A SUPERIOR court judge has upheld the Milpitas Unified School District's 2-year-old ban on the Wizards spelling game. The ruling was handed down last Friday. The computer game was banned in 1990 by the school board following complaints from parents that it promoted satanic worship. Teachers, seeking to reverse the ban, argued that it infringed on their rights to choose teaching materials, and broke laws prohibiting state agencies, such as school districts, from supporting any religion. The court ruled that the school district had acted within its authority and had not violated the California constitution by banning the game. "With all due respect, we don't agree with the court's decision," said Catherine Porter, an attorney representing the teachers. "Based on the California constitution, we do believe that we provided significant evidence to show that the purpose and effect of the ban was religious and not secular." Pleased by the ruling, Milpitas Superintendent Jack Mackay said, "We always thought the board was acting within its authority to maintain a secular environment." Porter said Monday that the teachers would be discussing whether or not to appeal the decision. shaun@octel.com ------------------------------ Date: Sat, 30 Jan 93 11:20:36 EST From: Norm deCarteret 813-878-3994 (TL 438) Subject: "Two charged with computer fraud in credit scam" Source: St Pete Times, 1/26/93, pg 3B, Tim Roche A personnel supervisor "who knew the ins and outs of a computer system that managed charger accounts for thousands of jewelry store customers along the Eastern Seaboard" and a former co-worker worked a scam using the supervisors ability to alter the computers database, illustrating the risks of: - inadequate controls within the computer system - retail store policy shortcomings - the procedure by which they let users who have had their card stolen continue to charge purchases - flaws in the system accountability "Using computer passwords of other employees, detectives said, Benjamin Francois was able to alter customer records and list a credit card as lost or stolen. Then his friend, John Wise, would appear at a jewelry store and claim to be the customer whose credit card was missing. By store policy, Wise only was required to give sales clerks a name, Social Security number and a secret code that would allow customers whose cards were lost or stolen to continue charging merchandise. "If the clerk asked to see some identification, Wise would explain ... he had no photo to prove he was the customer, but he would give the clerk the secret code Francois had obtained from the computer." Affected between June 2nd and last September were: - jewelry stores in Tampa, Orlando, Palm Beach and Altamonte Springs FL - Jewelers Financial Services, which ran accounts for: . Zales Jewelers, Bailey Banks & Biddle Jewelers, Gordons Jewelers Francois was able to delete the references to stolen or lost cards on the charge accounts after the purchases were made. The two men were arrested after a tip in November led police investigators to "verify the mainframe database" records. Of particular interest: system controls allow Francois to manipulate the database, then hide the activity so that, apparently, the real customers were not billed. If the report is correct, it was the November tip and not any system controls that revealed the thefts. Apparently the charges were allowed to fall into some sort of accounting black hole.

Scott Subject: Bible belt broadcast bungle Heard this on the radio this morning: a major Christian radio network is alerting its member stations to check their latest shipments of religious compact discs before airing them. It seems that some other CDs were mislabelled at the factory and shipped along with the religious ones. Unfortunately the itinerant CDs were by the Dead Kennedys. A spokesman for the radio network said, "This is what happens whenever people get around machines." The CBS newsreader, with masterful understatement, said, "The Dead Kennedys CDs included songs such as, `I Kill Children,' which some Christian listeners may not find inspirational." Peter J.

Sprint reported fraud claims by its business customers dived 96 percent, to $670,000, or $1,350 per incident compared to an average loss of $35,000 in 1991. AT&T says fraud claims made to it dropped about 88 percent and MCI says it has also seen a drop in claims. In other words, 1992 losses were a far cry from the $1 billion to $3 billion a year claimed as losses in past years. The major reason for the drop: customer awareness ------------------------------ Date: Thu, 28 Jan 1993 18:12:46 GMT From: barrett@forge.gatech.edu (James Barrett) Subject: Re: Clinton Transition Team E-Mail > Mail Delivery Failure.

There are no definitive studies that fully address the complexities of the situation, especially in view of increasing circumstantial evidence that non-ionizing radiation may have more biological effects than previously thought. It's true that walkie-talkies, ham radios, etc. have been around for many years--but there are some potentially significant differences with cellular phones: 1) Most walkie-talkie, police radios, ham radios, etc. are operated in a push-to-talk mode. You're only transmitting when you're actually talking. Cell phones transmit continuously, so exposure is continuous during calls. 2) Cell phones operate at higher frequencies than most common service or ham radios (common hand-held ham radios, for example, usually go no higher than the 440 Mhz band. Cell phones operate in the 800-900 Mhz region, which puts them just about in the microwave range. Recently there have been a number of concerns raised about microwave exposure to the operators of police radar units. We're talking longer exposure and higher frequencies in the radar case--but nobody knows where the "thresholds" might be for exposure to possibly show effects in some persons. The bottom line is that the higher the frequency, the more "energetic" the effects. In at least a couple of the cases of persons accusing cell phones of causing tumors, part of their evidence is the shape and direction of tumor growth--they apparently are aligned with the antenna and growing inward from the outside. Of course, this says nothing about cause and effect--but it has to at least be considered. It's true that cell phones use quite low power. But a little power packs a bigger "punch" at these frequencies, and with the antenna right next to the head the *field strength* (which matters more than the absolute power) can be quite high (inverse square law applies). Concerns about health effects from hand-held radios have been around for a long time. But with the millions of people using continuously transmitting, ultra high frequency units who never did before, some new dimensions are added to the picture--and they are definitely worthy of serious consideration. By the way, not all cellular systems are created equal when it comes to radiation exposure. The new CDMA digital system, for example, throttles back the power from the portable unit depending on how close you are to the cell site--the site transmitter sends a signal back to the handheld controlling the power level. The main reason for doing this is to drastically increase battery life, but it has the additional benefit of reducing overall exposure as well. --Lauren-- ------------------------------ Date: Wed, 27 Jan 93 17:03:44 PST From: andrew@frip.wv.tek.com (Andrew Klossner) To: pnm@goanna.cs.rmit.oz.au Subject: Re: EM Radiation - is smoking safer? (Menon, RISKS-14.29) "We've had walkie talkies (ok - two way radios) for years with no perceivable or admitted risk to the health of users." Not so. Long term (over 20 years) use of two-way radios by police officers has been linked to higher incidences of glaucoma. This is one reason why the transmitter unit is now worn on the belt, with the microphone pinned to the lapel. (This means that the transmitter irradiates the gonads instead of the eyeballs ... a possible new risk?) -=- Andrew Klossner (andrew@frip.wv.tek.com) (uunet!tektronix!frip.WV.TEK!andrew) ------------------------------ Date: Mon, 1 Feb 93 10:07:02 EST From: alanu@fitmail.fit.qut.edu.au (AProf Alan Underwood ) Subject: CERTIFICATION-PROPOSED US LEGISLATION >From Alan Underwood, School of Information Systems, Queensland University of Technology. e-mail alanu@snow.fit.qut.edu.au I am seeking assistance in obtaining copies of any current US/European legislation (proposed or enacted) for the certification of computing professionals.

The programme for the conference follows. If you do not think this is a suitable place for this but know of somewhere that is perhaps you could forward it or let me know and I will do so. FINAL PROGRAMME. COMPUTERS: SECURITY AND THE LAW 31 March - 1 April 1993 The conference will be run by the Department of Computer Science in association with the Society for Computers & Law and the Licensing Executives Society . The aim of the conference is to highlight some of the important legal issues that surround the use, and abuse, of computer technology in a way that should be accessible to the non-specialist, such as lawyers or computer scientists. The target audience for the conference is senior management and those in both public and private sector organisations who wish to improve their knowledge about the legal aspects of buying, using or creating computer related products and services. The conference will be of interest to the police, the civil service, banks, insurance and building societies. The programme will take place over two consecutive days. The first day will deal with the legal aspects of intellectual property rights, copyright and contract law as it relates to computer products and services. The second day will deal with the topics of computer crime and its prevention, security, data protection and privacy. The conference dinner will be a Medieval Banquet at St William's College (founded in 1461). The keynote speaker will be Emma Nicholson, MP. Proceedings of the conference will be published and be available to participants after the conference. REGISTRATION AND FEES: Delegates will be able to register for either of the two days separately if they wish.
