HARRISBURGH, PA (AP) -- Authorities accused a computer operator from a company that helps run the state lottery of forging a winning $15.2 million ticket and another man with trading it in for the jackpot. Mark S. Herbst, 33 of Harrisburgh, was arraigned Tuesday less than a week after he traded in the ticket for the first $469,989 installment of the prize from a Super 7 drawing last July 15. He was jailed in lieu of $50,000 bail. Jailed in lieu of bail Monday night was Henry Arthur Rich, also 33 of Harrisburgh. Officials alleged Rich used of computer at his firm, Control Data Corp., to identify unclaimed jackpots and to print a copy of the unclaimed winning ticket, which he gave to Herbst to cash in. Officials became suspicious, in part because the bogus ticket was printed on a blank from a Scranton lottery-ticket outlet, while a computer check showed the actual winner was sold in Bucks County.

I just received some marketing information from Radian Corporation (of Austin, TX) about their product CHARM ( = Complex Hazardous Air Release Model). Basically, CHARM provides software simulation of airborne toxic substances release (isopleths based on cloud density, wind, temperature, etc.). Radian states that "[m]ore than 85 users in industry and local, state, and federal agencies are using CHARM to develop emergency response plans, to train personnel in emergency response procedures, and to rapidly assess real-world situations should they arise [sic]." For some reason, after reading the above I am morbidly amused by the fact that Radian includes in the License Agreement the usual disclaimers: "The program is provided 'as is'..." "The entire risk...is with the customer." "Radian does not warrant...that the operation of the program will be uninterrupted or error-free."

"ERIC" and "VULT" Identified ERIC and VULT, the specific targets of the SCORES Apple MacIntosh virus, were internal projects at EDS in Dallas according to EDS spokesman Bill Wright. These labels identify proprietary trade secret programs that were once, but no longer used at EDS. While SCORES was specifically designed to destroy these applications, it would infect anything. All the above was gleaned from "Macintosh Today," May 2, 1988 which also contained a highly speculative article entitiled "Viruses: Nothing to sneeze at." If you believe this article, computers have seen their day. In the future, viruses will make them unuseable.

I also recently received an unsolicited request to run an enclosed disk for the purpose of evaluation. This disk was from IntelliQuest in Austin. This disk was a "User Interface Prototype" reportedly under development by Ashton- Tate. Since no AT logos were in place anywhere and I had read all the recent reports of viruses in RISKS and elsewhere, I was suspicious. I have an old Bernoulli Box as my hard disks so I unmounted them and fully intended on powering down after using the disk. Upon booting the disk, I was shocked to see "DRIVE C: NOT READY". I then place every write protect possible on the [[[blanks in received mail]]]. I assume one of the first functions done by the interface is to check the C: directory. The program booted, but was unable to impress me. I was contacted last week by IntelliQuest and spent about 10 minutes talking to them about the product and my negative opinion of it. I am confident that modern day electronic vandals would not spend the time or money to call me from Austin. In short, trust the dealer but always cut the cards. Fred McKay
My bank recently mailed out new ATM cards to all of its cardholders, mostly as advertising for a new network. Familiar sounding RISK? The way that this bank handled this risk merits mention: They placed telephone calls to each of the card-holders that it mailed new cards to (at least that's what the voice on the phone told me). Perhaps such a telephone followup could serve to limit some of the risks mentioned in previous entries; from personal experience trying to sell newspapers via telephone in New Jersey, such a verification could be done quite cleanly, especially since people will be much more willing to determine if their new ATM card arrived than to subscribe to a newspaper!
> ... Paying cash is the only sure way to avoid this. [David Chase] The local videotape rental store has an XT clone w/ a hard disk on which they keep a record of every tape that you've ever rented. All the clerks have access to this information. Of course, because you're renting, paying cash is insufficient to preserve your privacy. Hmmm... libraries must preserve confidentiality; why not video tape rental shops?
Since I was the individual who told this story to Joseph, I suppose I should verify it and add some authenticating details to it. I was told this story by Professor Alan Epstein of the MIT Aero/Astro department during a talk of his during MIT's Independent Activity Period of January 1985. The talk was titled, "Testing Jet Engines: Why It Takes All the Money in the World". Anyone who really wants to nail this down precisely should ask him. The reason this story is so important is that it demonstrates the unfortunate interaction of several design failures, each of which alone should not have led to cabin depressurization (not to mention the passenger who went out a rather small hole). The aircraft involved was some Boeing flavor, 727 or 747 type. The first failure was in the crew, which should not have been playing games by doing this sort of experimentation. They got very long, unpaid beach vacations for their conduct. The second failure was in the autothrottle mechanism itself, which did indeed read its input from the panel display in the cockpit rather than directly from the tach in the engine. I can't imagine what possessed the engineer to read input from something with a breaker in the path, but that's neither here not there. Even worse than this, though, was in not detecting an obviously open-loop (i.e., bogus) value of a sensor, and in thus generating wild control signals that should never have been generated. (After all, sensors DO fail.) We saw this sort of failure in the PDP-11's controlling the blast furnace (in some RISKS about two months ago). The control circuit should instead have insisted on some sort of manual intervention (though, as we'll see below, such manual intervention could not have arrived in time to save the aircraft), or at least "failed safe" by leaving the engine running at the same speed as before (and bleating loudly that something's wrong). The third failure was in the engine testing itself. Here are the details. When the breaker was flipped, the autothrottle circuit for that engine went open-loop. When the engine reached 109% of maximum rated power (about a second later), it stalled the compressor blades. This means the compressor wasn't compressing efficiently any more, allowing a blast of essentially white-hot air to come out the FRONT of the engine. This blast of air started an oscillation in the front set of engine fanblades, which rubbed on a cowling and started a fire. The fire fed the oscillation, because of timing and positive feedback between pressure regions and the flame at the cowling. Elapsed time is now about a second and a half from the breaker being flipped. After enough abuse (the fanblades were not designed for highspeed oscillation in this axis), one of the blades of the frontmost fanblade assembly failed at the root. Now, jet engines are designed and tested to withstand a blade failure. The failed blade supposed to get chewed up and go out the back of the jet. I've watched tests in which they have blown up explosives at the blade root to simulate just such a failure, in a jet on a stationary test stand at full power. Even though the engine is not expected to run after this happens, it's expected to shut down cleanly without tossing anything radially out the wall of the engine. This failure was different, because such tests are not made with the compressor blades stalled (I suppose that no one ever realized that the jet would be run stalled, since the normal control channels probably can't run the engine up to that speed). Since the compressor was stalled, air was blowing out the front of the jet, rather than the back. This forced the broken blade out forwards, at which point it was no longer constrained by the body of the engine, and was free to fly off radially---in this case, through the fuselage. The blade went through the fuselage less than TWO SECONDS after the breaker was tripped. The three failures---human, electronic, and mechanical---are an example of how tightly coupled such failures can be. They are also an example of just how fast such failures can occur: the higher the power level being controlled, the faster such failures can take place, because there's more energy available to cause things to fail. The explosion of the Shuttle was a similar lesson in power densities. (For comparison purposes, one 747 on takeoff roll is generating 400 MW total [100 MW/engine]. An aircraft carrier generates about 120 MW all told; a large nuclear reactor, 1200 MW or 1.2 GW; the Shuttle on liftoff, about 7 GW.) Incidentally, while the engine did indeed fail and toss a blade radially, I'm inclined to believe that the human and control failures were the real failures here. Almost any engine can be made to fail if it's purposely driven beyond its performance envelope (witness the short life of racing car engines, which run at the ragged edge). The real problem here was in allowing any AUTOMATIC control circuit to force the engine outside its envelope. (I can see why a human might be given the benefit of the doubt---if the engine is being overstressed to avoid a head-on collision, for example, I'd rather let the human do whatever he likes if it might save the aircraft, even at the risk of blowing something up, rather than keeping the engine nice and safe and letting it be destroyed [along with the passengers!] in the resulting collision. If the engine fails in such a case, well, it wasn't supposed to work under those circumstances anyway, but if it DOESN'T fail, then allowing deliberate, considered operation outside its rated envelope might save the aircraft. But an AUTOMATIC system should never be given the benefit of such doubt!---because now you're designing with two sets of inconsistent constraints.) <LNF>
In RISKS 6.76, Stanley Quayle described another intrusive Social Security Number practice. Here is an account of some of the RISKs of _not_ giving out your SS# freely. Overall, I find these risks more acceptable than those on the other side, but there have been times . . . For the last decade, I have declined to give my social security number to anyone other than those that are entitled by law to have it. I have been refused credit on a number of occasions because of this, but have encountered no serious problems in getting credit that I needed. For example, I have a full complement of credit cards that have no annual fees. Some of the larger credit data banks, such as the one operated by TRW, apparently require the SS# in order to access _anything_. While some organizations refuse to deal with me, others with more sensible policies simply check my banking and mortgage references, which show a perfect credit history, and give me credit. (I have a sneaking suspicion that one or more of my credit references may have given away my SS# without authorization, but I know of no way to determine this.) When I returned to Stanford University in 1985 and signed up for medical and dental insurance, I was told that the identifier that would be used for these services was my SS#. "Over my dead body," I said. I pointed out that doing so would tie my medical records to my government and financial records and that I preferred to keep these things separate. The Benefits people expained that "Stanford has contracts with the insurance companies that require that we give them your Social Security Number." I pointed out that they had a contract with me to provide medical insurance, that I consider my SS# to be confidential, and that it was up to them to solve this problem. I also pointed out that it would be relatively easy to add one field to the personnel data records for an "Employee ID" that could be used instead of SS#. Incidentally, I believe that the insurance companies prefer to use SS# instead of employee number because it makes it easier for them to cross- connect medical records from different periods, which is occasionally useful in fraud investigations. Of course, this same feature also makes it easier to find medical reports for the purpose of political or other harassment. The Benefits people dithered over the problem I posed for a couple of months while I harassed them. They finally decided that instead of augmenting the Personnel database, which they apparently regarded as next-to-impossible, they would give me a phoney SS#, which would be changed to the correct one just before they sent W-2 forms to the government at the end of the year. I was suspicious that this wouldn't work and said so, but agreed that it would theoretically meet my needs. The Benefits office asked one thing of me: that I not tell anyone else that they were doing this. They were apparently afraid that there would be a mass of troublemakers who would exceed their capacity to cope. They subsequently demonstrated that they were not even able to cope with me. I did manage to get my dental checkups paid for the first year, but I had a hunch that I was not home free. At the end of the year, I called Accounting to make sure that my earnings would be reported to the government under my true SS#. "Oops," was the reply, "We'll send them a correction on that." A few months later I received a copy of a letter to Stanford from TIAA-CREF, which manages my retirement account, asking where the bizarre SS# came from. Fortunately, they had somehow been able to figure out who I really was. Things went fairly smoothely after that until Benefits decided to give me another phoney SS# in 1986. That one caused the dental charges to bounce, so they gave me another phoney number, which also didn't work. They then announced that the only way to get those bills paid was for me to use my true SS#, which they acknowledged they had given to Delta Dental. I sent them a rather nasty and threatening note and they subsequently managed to get the bills paid and to make the new phoney SS# work. I understand that the Personnel Department is now in the process of converting to Stanford employee numbers instead of SS# as the basic identifier, which they should have done long ago. I would like to think that I helped stimulate this conversion, but there is no direct evidence. It is clear that I brought most of the problems described above on myself. I would (and probably will) do it again. If you wish to straighten out the world, you have to do it one piece at a time. Les Earnest
