She goes on to state that not only are the researchers comparing "apples to oranges" in terms of the types of technologies surveyed (punch-cards versus optically scanned and DRE machines), but they have misleadingly compared Gubernatorial general election results to Gubernatorial primary results (and only for the Democrats in the 2002 primary). It is well known that voters in general elections turn out in far greater numbers (in Florida it is estimated that the November election will show a 400% increase or more) than in primaries, putting greater strain on the performance of systems as well as on poll workers and voters. The balloting style of the typical primary voter (usually a party insider, and certainly a partisan with a larger interest in selecting candidates for each race on the ballot) is quite different from the general election voter, where independents and other non-declared or minority party affiliation citizens are permitted to cast ballots. Thus, only in November will we be able to ascertain whether the residual vote rate has actually "improved." Hence, Dr. Mercuri asserts, "the conclusion is premature, as well as flawed." Laudatory statements made by Stephen Ansolabehere, Charles Stuart and R. Michael Alvarez regarding Florida's new voting systems are also sorely misleading, and do not support their conclusion of 35% improvement. MIT Professor Stuart's comment that "most of the problems covered by journalists...did not concern equipment malfunctions" is not based on an analysis of the numerous and severe voting system problems that occurred throughout the state, but rather on the media reports that surfaced. Many equipment malfunctions were reported by the Associated Press and other news bureaus, but these were obfuscated by the public interest stories that alternatively showed voters "pleased with the new equipment" or being "turned away from the polls in droves." A lot of the media attention focused on press comments by Governor Jeb Bush and members of his staff who erroneously characterized the problems as being based only in two counties (Miami-Dade and Broward) and blamed the poll workers and election officials there for the situation. In actuality, Miami-Dade and Broward could not have purchased the ES&S machines had they not been pre-certified by the state for use. Sadly, this certification failed to provide the counties or their poll workers with sufficient notification as to the fact that the voting machines would take 10 minutes to start up, with the ones outfitted for the visually impaired taking an astonishing 23 minutes. Some machines also contained a "safety feature" that did not permit them to be turned on before 6AM on election day. Since each unit is activated sequentially, simple math shows that a polling place containing 10 voting machines, with one outfitted for the visually impaired, would not be fully operational until nearly 8AM (an hour after the polls opened) under the best conditions. Mercuri states: "I certainly do not see how this can be blamed on the poll-workers, nor how it constitutes an improvement. I'm hard pressed to think of any computer equipment manufactured after the 1970's that takes 23 minutes to be started, especially those deployed for use entirely in time-critical operations. The failure by MIT/CalTech to raise serious concerns about the engineering of these products is remiss." MIT's Ansolabehere stated that "the machines used showed clear gains over the technologies used in past elections." To which Dr. Mercuri replies: "Yes perhaps, if one considers declaring a state of emergency (under threat of lawsuit by a major candidate) and extending the election day by two hours a "clear gain." How about in Union County, Florida, where 2,700 optically scanned ballots had to be hand counted, because the computers were erroneously programmed to only tally votes for Republican candidates? At least there, the ballots could be recounted because they were on paper. What about the precinct in southern Florida that showed a 1200% voter turnout (12 times as many voters as were registered) because the DRE activation cards permitted voters to cast ballots on machines in the same building that were not in their precinct? And what about some precincts in Miami-Dade and Broward where the vote cartridges reflected over 40% residual votes (lost or missing) and data had to be "extracted" from back-up memory inside of the machines (one wonders how trusted the reconstructed results can be)?" CalTech's Alvarez states "we are learning important lessons about how to make such important changes in voting technologies" and Mercuri asks: "Is it fair to allow Florida and other states and communities to feel pressured to replace their voting systems while being treated as guinea pigs? Is the United States prepared to reimburse communities for defective and obsolete equipment once new standards are in place (since all election equipment is still being inspected by the National Association of State Election Directors testing authorities to the outdated 1990 Federal Election Commission guidelines)? Is it acceptable to certify voting equipment that can be reprogrammed internally via a portal on the device (as some were, only weeks before the election in Palm Beach County as well as elsewhere in the state)? These new technologies are playing a role in electing government officials - the confidence citizens have in the democratic process is at stake." Mercuri, who has testified before the U.S. House Science Committee regarding the need for involvement of the National Institute of Standards and Technologies in establishing criteria for the procurement and testing of election equipment, feels that congressional election reform is sorely needed. But, she notes that many of the laws proposed at federal and state levels, or enacted since 2000, have been weakly worded so as to permit the production of election equipment that does not provide an independent means whereby voters can verify human-readable ballots that are secured and available for recounts. "Real election reform," Mercuri says, "is only possible within a context of adequate and enforceable standards for construction, testing, and deployment of voting equipment." But Mercuri worries that the trend to full automation of the voting process could be used to conceal election fraud. She warns, "It is entirely possible that Florida and other states may smooth out their election day problems such that it appears that the voting systems are functioning properly, but votes could still be shifted or lost in small percentages, enough to affect the outcome of an election, within the self-auditing machines. Whether this occurs maliciously or accidentally, it presents a frightening prospect. Thankfully, new products are being developed that provide the voter with a way to determine that their ballot has been tabulated correctly, without revealing the contents of their vote, but deployment of such systems is a few years down the road." For these reasons, Dr. Mercuri has requested a moratorium on the purchase of any new voting systems that do not provide, at minimum, a voter-verified, hand-recountable, physical (paper) ballot while appropriate laws, standards, and technologies are developed that will provide accurate, secure, reliable, and auditable voting systems. She urges MIT, CalTech, and other concerned scientists, public officials and private citizens to join her in this cause. For further information contact: Rebecca Mercuri, Ph.D. P.O. Box 1166, Phila.

The driver, who had been chatting with railway workers on the platform, did a 100-yard sprint to catch up with the train. However, a spokesman for Valley Lines reportedly said that the train would have stopped automatically in another fifty yards. [Source: All Aboard! Except for Driver of Runaway Train, Reuters item, 18 Sep 2002, via Yahoo; PGN-ed; perhaps the driver was in training (sprintwise)?] http://dailynews.yahoo.com/news?tmpl=story2&u=/nm/20020918/od_nm/train_dc ------------------------------ Date: Fri, 13 Sep 2002 20:27:30 -0400 From: Bruce Anderson Subject: Greek government doesn't quite ban electronic games This one sounded too far out, so I checked with the local Greek consulate. (My question to them was "is this a hoax?", quoting the Web page referenced in RISKS-22.23.) Here is their reply. I hope this clears the air a bit. After we received your e-mail we have forwarded it to the Press Office of the Greek Embassy in Ottawa. They have informed us they are aware of these articles but they are not accurate. The New Greek Law has banned all games that can be used for gambling or modified for gambling purposes even if they exist in private spaces (Only Casinos are excluded from the banning). However neither foreign tourists neither Greek citizens will be prosecuted when they use cell phones with games , or lap tops in which games are installed or any portable game consoles for example :play stations, gameboys, x-box etc, since these games cannot be modified for gambling and furthermore the owner doesn't insert coins or credit cards in order to continue using them. We hope that this answers your question. ------------------------------ Date: Thu, 12 Sep 2002 02:50:13 -0700 (PDT) From: Michael Ortega-Binderberger Subject: Yet another intrusive Web site A few days back, and with the september 11 anniversary, a local news station in Los Angeles, CA (reasonably large audience) advertised the efforts of a Web site called 4MyEmergency.com. The idea is that most people do not have all their personal information "together" in case of a disaster, and the Web site wants to help you get your act together. Its full of good wishes, privacy pledge, etc. so far so good. What the Web site does for you is to generate a report that you can leave with a loved one in case of disaster. Unfortunately, disaster can come much earlier thanks to its information gathering process. It asks you in a series of 7 forms all conceivable information about yourself: name, address/phone, birthdate, names/phones of family, friends, your doctor,dentist, pharmacist and insurance agent, your medical history, home, car, health and life insurance policies (the company, phone, policy numbers and where they are), home security company and even though they don't "recommend" you give them your security code, yep, there you can write it down if you so choose. To make you feel good, you can also include your religious and pet information to go with your credit card, banking, accountant, attorney and real estate information. Its actually so concerned with security that it does not ask for your social security number, you can just write it down on the final printout, or "mail it to a friend or family member you trust". The homepage states that "For additional security, this Web site uses the highest level encryption." However, all of this is transmitted in the clear with not even SSL encryption to a Web site that has no credibility beyond good wishes and a click-through privacy agreement. To be fair, most fields are optional, but then, why would anyone use it in the first place? The RISKS? The information they collect is tailor made for identity theft, they have no security, and the media is giving them a free pass and even some promotion despite frequent warnings about identity theft in southern California. ------------------------------ Date: Wed, 11 Sep 2002 16:25:51 +0100 (BST) From: George Roussos Subject: Air passenger jailed for using mobile A passenger who played a game on his mobile phone during a flight has been jailed for four months.

I just had Windows 2000 installed on my laptop (company policy). This software ships with very little security enabled and numerous webs sites, including Microsoft, tell me to update it and change account settings. But it is so hard to figure out what to do! We are told to change the Admin password, but also warned that some (unnamed) programs will stop working if we do this. The computer help files and Microsoft web site do not tell which accounts are needed or why. What I can tell is my machine has now been changed into a multi-user environment, which is not what I want. Also Microsoft tells us to use "snap-ins". What on earth are they? Which ones affect which accounts? I can't make random changes to my machine, as it has to work within a corporate network. I think the reason this is so confusing is Microsoft does not know what are the correct settings for the many pre-installed accounts and is trying to make its users figure this out on their own. Otherwise, wouldn't the software be shipped with appropriate settings already enabled? ------------------------------ Date: Wed, 11 Sep 2002 17:05:10 +0000 (UTC) From: abuse@mooli.org.uk (Peter Corlett) Subject: Re: The pinnacle of chutzpah in spam filtering > [Why you'd have a content filter on an 'abuse@...' is beyond me.] > [Because they get lots of spam also? PGN] Yes. I adopted a username of "abuse" in 1998 or so to reduce the amount of spam I received. It was rather effective. Still, the thieves who want to steal my bandwidth have now added the new address to their "Trillion Guaranteed Addresses" CDs and there's a reasonable chunk aimed at my MX hosts. The MX hosts run abuse@ through my hand-crufted Exim Filter rules and issue bounces. They're based on header peculiarities caused by certain popular bits of spamware, so the usual risks of keyword filtering don't seem to apply in my specific case. I include a phone number in the bounce, and nobody has complained yet, anyway. When I used to work on an abuse desk, we had an incredible amount of junk sent to the abuse@ address as well. Unfortunately, it wasn't sensible to attempt to filter that lot, exactly because of the noted RISK. Besides, I wouldn't get the BOFHly pleasure of nuking a user for spamming if I'd lost the complaint :) ------------------------------ Date: Wed, 25 Sep 2002 17:48:05 -0400 From: karger@watson.ibm.com Subject: Re: Retrospective Karger/Schell paper on Multics Security Evaluation Since our paper was reviewed this week on both RISKS (Summit, RISKS-22.25), people who downloaded it may be interested in obtaining a newly revised copy that includes a few small changes based on some of the comments and suggestions we have received, as well as some typographical corrections.

In recognition of this book's demonstration of your deep personal commitment to recycling (and at least you admit that this story started life as "Terminal Compromise": many don't) I was going to reprint my original review (cf. BKTRMCMP.RVW) but I suppose that wouldn't be fair to anyone. You have tightened up the writing considerably. (With age, and a few more books under the belt, comes grammar, eh?) However, I still note "refuse" for "refuge," a semicolon for "that," "hesitancy" for "hesitation," and a whole lot of redundancy. (And what is with your fetish for "Glen Fetich"?) Your characters are a little more interesting and consistent, although Miles Foster (and most of the other technical people) still seem to be geek wish fulfillment. The plot has more tension, but it is still *way* too convoluted. You've got a whole shoal of red herrings (and you know what they say about old fish after a while) and a ripped-out wiring closet full of loose ends. Even disregarding a computer system that will crack Blowfish and AES in seconds, and the wonderful, mythical lethal virtual reality feedback bug, I still have some technical bones to pick with you. Why does a power outage shut down a battery operated radio? Carbon dioxide does not suck oxygen out of the air. And my son-in-law is a pilot on that type of aircraft, and has had power failures at exactly that point in the flight (the latest due to a lightning strike). My grandchildren aren't orphans yet. I couldn't ignore your "virus" now, could I? In having it burn out a printer port, were you trying to resurrect the old "Desert Storm virus" canard? I recognized the old timing based video burnout trick and the somewhat debated issue of excessive diskette read head travel (neither was ever used in a virus). But, for crying out loud, if you sold three hundred million "infected" programs, why would you need a virus? And if you distributed that many copies of malware, you think nobody would notice? (Yes, OK, "Windows." Partial point to you. But people are finding bugs in it every day.) I agree with your basic point: the general public should be more aware of the weaknesses in the technology that controls so much of modern life. But you don't strengthen your argument by making enough mistakes that it looks like you don't understand it either. copyright Robert M.
