Only 1/3 of Government Computers Down So Far

-----BEGIN PGP SIGNED MESSAGE----- Allegations Regarding Vince Foster, the NSA, and Banking Transactions Spying, Part XV by J. Orlin Grabbe The world of money laundering is a difficult one. What are you going to do when your wire transfers to the Caribbean and other offshore centers won't go through? What are you going to do when one-third (as of August 8, 1995) of certain government computers are down with a virus? Or is it a worm? Or an octopus? Did the NSA, in its zeal to modify the PROMIS software to spy on banking and other transactions, create a massive security hole in computer systems sending wire transfers? Well, I do hear it is a nice time to go vacationing in the islands, even for day trips! Perhaps FinCEN could relocate to Havana? [Note to Julie Franklin: Over here in Reno, we're always last to get the news. Well, I'm a taxpayer. *Please* put me on your list. In the future please fax all computer disconnect info to 702-829-0852. Thanks.] Which brings us to the subject of Ed Meese. At the end of Reagan's second term as governor of California, Meese needed a new job. He worked at Rohr Industries for a while. But it didn't suit him, so *Richard Mellon Scaife* set up the San Diego Center for Criminal Justice on condition that Ed Meese be its Director, a post Meese held 1977-1980. Later, after Ed Meese became Attorney General of the U.S. and the the people-tracking PROMIS software was stolen by the U.S. Justice Department using (according to a federal bankruptcy judge) "trickery, deceit, and fraud", Ed Meese's friend Earl Brian--then owner of Financial News Network, UPI, and Hadron corporation--proceeded to market the software all over the world, as well as to U.S. intelligence and law enforcement agencies. One agency that acquired the software was FEMA, the Federal Emergency Management Agency, which proceeded to create a data base of political dissidents to be rounded up in event of a national emergency. (Like any information, once collected it found multiple uses.) This data base was called MAINCORE, and the FEMA MAINCORE system was operated out of the basement of a building in Culpeper, VA. Journalist Danny Casolaro, with the help of Alan Standorf, was able to get printouts of this totalitarian application of the PROMIS software just prior to his demise. (When a member of congress attempted to question Oliver North about the FEMA MAINCORE data base, he was rudely shouted down by the chairman of the investigative committee.) Another agency that put the software to use was the Wackenhut Corporation. It used the enhanced PROMIS to keep track of critics of the nuclear industry, an area in which *Richard Mellon Scaife* has a vested financial interest. Now Mellon bank in Pittsburgh finds itself embroiled in very serious money laundering charges. Do these facts explain why the Little-Rock connection to the theft and modification of the PROMIS software for the purpose of spying on banking transactions is a subject carefully avoided in Scaife-sponsored political advertisements? Is this why the Mena-drug-smuggling, Little-Rock-money-laundering operation allegedly stops with Bill Clinton? Is this why the connection of Vince Foster both to bank spying and nuclear espionage has been carefully downplayed? Do Scaife's investments in the "terrorism industry" have anything to do with recent media hyping of the imminent threat to the U.S. of "international" terrorism? Scaife's exposing of the sins of the Democrats has certainly served a useful purpose. But don't think the story stops with Bill Clinton. Perhaps the reason that Mr. Kenneth Starr's independent investigation into the Whitewater affair has gone so slowly is that Mr. Starr, in order to nail Bill Clinton, has to also nail a number of high-ranking Republicans? Well, Mr. Starr, let the facts fall where they may. I have confidence in you. You do want to be Attorney General someday, don't you? If you can find your way to do the right thing, you'll certainly deserve the position. Otherwise the wily hackers of the world may have to do your job for you. -----BEGIN PGP SIGNATURE----- Version: 2.6.2 iQCVAwUBMChlMWX1Kn9BepeVAQHbhgP/bSlSNnUClp4HPEDiB22JGHrqvMa5B6h8 LW0rR7eZdD2ub9CUj/HBfIrnU4mekw6MfmExxuy+mva1Z5MPsZKuE1qvxWBFHK5S TzMFsPBsZNPH2GEDIQHZp/rIQeKYDsfjOp1OLVUPD9MA4tlTOQPgQ5RVzzKi+tEF K1+Uxvy1lQ4= =5pPJ -----END PGP SIGNATURE-----

Dir.Byway Virus (NewsClip)
by anonymous-remailer＠shell.portal.com 17 Dec '03

Is this legit? ---------- New Computer Virus Attacks "Everything" Burlington, Mass. Aug. 7 -- A new, hazardous computer virus is spreading, that takes control of disk operations from Microsoft MS-DOS or IBM PC-DOS based systems, the anti-virus research team at S&S Software International is reporting. The virus, dubbed "Dir.Byway," is described as a super-fast, polymorphic infector affecting desktops, notebooks, and even computer networks. Pat Bitton, S&S Software vice president of marketing, told Newsbytes the virus is a very "dangerous" one. Because it is polymorphic, it mutates with each attack, making it extremely hard to diagnose and kill. The virus operates as if it is a TSR (terminate and stay resident) program, infecting .COM and .EXE files when the home directory of an executable file is accessed, officials said. Infections are not confined to the default home directory either, but infects all executables in all directories of a search path. In addition, the access does not need to launch an application. Any kind of access triggers the virus, like looking at a simple directory listing. This ability to infect everything in its path makes Dir.Byway a "super-fast" infector, officials added. The virus creates a file called "CHKLIST . MS" (without quotes, but with spaces surrounding the period) in the root directory, and cross links all infected executable files, David Emm, customer service manager, told Newsbytes. This then replaces the normal DOS directory entries, making "CHKLIST . MS" the start-cluster for every infected file. If the user deletes the file, it reappears when any infected file is executed. Also, if the user boots from a clean DOS disk and runs "CHKDSK," the computer will report a large number of cross-linked files. If the user boots from the infected hard drive, the computer will report no errors. A listing of the root directory using the command "dir/ahs" (without quotes) will show the "CHKLIST . MS" file. Dir.Byway triggers if the current DOS date is set to the year 1996 or above, and the day of the month is equal to the month's number multiplied by two and two is added, like in 01-14-96 or 12-26-96. When triggered, the virus displays a string of text every three hours, on hours that are a multiple of three in military time -- for example, 09:00, 12:00, and 18:00. The text says: "Trabajeoms Todos Por Venezuela." S&S officials said this translates to "We are all working for Venezuela." On multimedia systems, this is accompanied by a song that resembles the country's national anthem. Emm said he is more worried about the spread of the virus for now than the triggering of it, because it is so dangerous. He told Newsbytes the virus has been detected in the United Kingdom and the United States. Bitton said the company's "Dr. Solomon's Anti-Virus Toolkit" will remove the virus from infected computers. New versions of the Toolkit for DOS, Windows, OS/2, and NetWare are slated to ship in late summer. S&S also plans Fall 1995 introductions of Toolkits for Macintosh, SCO Unix, Windows 95, and Windows NT server and workstations.

PGP at work?

Sorry for the FAQ. Really, I've spent the last hour scanning the distributed docs and hopping around to different web pages looking for this info. What constitutes ``commercial use'' of PGP? I could swear (if I were a theist :-) that I'd seen some sort of statement from RSADSI, PKP and/or MIT that it is ok to use PGP for mail at work providing that the *purpose* of the mail is not commercial. Could someone confirm or deny this, preferably with a reference? -- Rick Busdiecker Please do not send electronic junk mail! net: rfb(a)lehman.com or rfb(a)cmu.edu PGP Public Key: 0xDBD9994D www: http://www.cs.cmu.edu/afs/cs.cmu.edu/user/rfb/http/home.html send mail, subject "send index" for mailbot info, "send pgp key" gets my key

Crypto = Competitive Advantage?
by Duncan Frissell 17 Dec '03

17 Dec '03

Note to Mr. Bill - I was watching CNBC this morning while reading my mail and they had a story on the Netscape Communications IPO (ticker NSCP btw). Some analyst said when asked whether Microsoft couldn't just wipe them out that the most important part of Netscape's product was that it offered end-to-end encryption. He said that this was important for the growth of the nets and was something that people wanted.

A former member of our list, Marc Andreessen, just became worth $70 million or so in today's IPO. (IPO = Initial Public Offering, or "Internet PGP Offering") Personally, I think this valuation of Netscape at a few billion dollars is way too high. They've got a leading product, which most folks have gotten for free, and they've signed a bunch of corporate deals. But a few billion for a brand new company? ...and who knows how many of their sudden multimillionaire developers will now leave...? Crypto could be the next big wave of IPOs, with "Verisign" and "RSADSI" both rumored to be offered. Some of the digital commerce companies may be next. It seems that anything involving the Internet, the Web, and digital commerce is really, really hot. --Timothy C.

It may have "opened" at $28, but the first bid was $71 and now it's trading at $50something. Not quite so spectacular as at first glance... So unless you shorted it or were an insider it wasn't such a hot thing (so far).

Bank Fees and E-Cash
by Black Unicorn 17 Dec '03

17 Dec '03

-----BEGIN PGP SIGNED MESSAGE----- - - - Bank Fees and the E-cash Niche. Banks have gorged themselves on rocketing fees for the last five years. The result is that typical bank customer currently pays 150% of the amount of interest collected on accounts in a given year in the form of fees. My prediction, and my hope, is that e- cash will cut through the pretense upon which the rationalization of many of these fees is based, and even market itself on this point- Lower Fees. - - - New Fee Schemes "Overdraft Assistance" and the Myth That Only Irresponsible Bank Customers Bounce Checks or Overdraft. Banks have begun to implement policies intended to help the customer overdraft. They may, for example, cash the largest checks first such than an overdraft will hit with several small checks rather than one or two large ones causing multiple overdraft fees. Banks have begun to routinely delay crediting checks for 48 and 72 hours, and out of state checks for anywhere from 3-14 business days. ATM cash deposits are typically subject to 24-48 hours delay. The "Unofficial Credit." Many times the delays in crediting various transactions are hidden by the "unofficial credit." Most noticeable in ATM deposits, a credit is given but should demands on the account draw into the "unofficial credit" an overdraft will be posted on the rationale that an "official credit" has not yet been posted and the funds are thus not "officially" available, this despite the fact that the funds will appear available to ATM balance requests and statements. Of course the bank will profit from the "unofficial credit" to "official credit" interest float regardless of what overdraft fees might be charged. The "wire credit" and "official wire credit" are another example. Banks receive a wire transfer on Monday, send a "electronic payment advice" the same day, but post the credit to the account "officially" on Tuesday. The original intent is for the bank to be able to take advantage of the interest "float" between the receipt of funds and its credit to the account. The result is an additional overdraft potential. The Separate Wire Office Hours. Often times the bank's "wire" office will close hours before the branch closes. Wires received some hours before closing on Friday will not be credited until the following Monday. The ATM Processing Time Table. Many bank only begin processing ATM deposit transactions an hour before closing, crediting only as many deposits as can be processed in this time, the remainder are not processed until the next morning. ATM debits are, of course, processed all day. Check Processing Time Table. In a given day, debit checks are processed on an account before deposit checks are processed. Obviously, an account that overdrafts overdrafts only because of the order in which checks are processed. - - - The Created Convenience Fee A great many bank fees fall into what I call "created convenience fees." Really created convenience fees resemble airport customs bribes in third world countries. The customs officer makes what should be an easy passage terribly difficult, then demands a "fee" to make travel as easy as it should have been to begin with. The net effect is for the traveler to pay to dispense with a problem created by the party receiving the fee. Nigeria is a prime example. Upon arrival the average traveler will find him or herself embroiled with licensing deficiencies, visa fees, entry fees, the threat of quarantine, seizure of expensive equipment for "inspection" and other such invented requirements. Some hours into the "negotiations" the customs official will offer to "overlook" these transgressions for a "fee." This is a created convenience fee. Banks fall into this category by such programs as "overdraft insurance" whereby banks enact policies which, as we have seen, make it painfully easy to overdraft and then charge a monthly fee to avoid the overdraft charges. - - - The Result Bob is a sort of combination of my own experience and discussions with other bank customers in D.C. Bob has an account in Washington, D.C. with $1500.00 in it. Bob Receives a wire at 3pm Friday for $1700.00 Bob writes five checks on Friday, one for $1400.00, one for $200.00, one for $150.00 and two for $100.00. Totaling $1950.00. Bob deposits 4 checks totaling $2000.00 in the night depository Saturday. Bob deposits $50.00 in cash in an ATM on Saturday Night. Bob checks his ATM balance ($3250.00) and withdraws $50.00 from an ATM on Sunday Morning. Bob's wire arrives after the wire office has closed for the day - an "unofficial credit" is posted Friday before closing anyhow. Bob's bank processes the $1400.00 check first, leaving Bob's account with an "official" $100.00 and $1700.00 in "unofficial funds." Bob's bank processes the $200.00 check, notes a $100.00 overdraft, charges $25.00 for this check, refuses payment on the remaining three checks and drops a $25.00 overdraft fee plus a $10.00 "bad check" fee for each. Total charges: $130.00 Bob's bank processes the $50.00 ATM withdrawal, which overdrafts. $25.00 fee is posted. Total fees so far: $155.00. Bob's balance for the majority of Monday: -$255.00. Bob's bank begins to process deposits, notes all the checks for deposit, $1000.00 of which are out of state. No checks are credited. Bob's bank notes the ATM transaction at the end of the day on Monday, but does not credit it immediately despite the fact that it is cash. Bob's bank credits the ATM deposit to Bob's account on Tuesday. Bob's balance is now -$205.00 Middle of the day Tuesday, Bob's account has been below its required minimum $500 balance for 24 hours. A $50.00 fee is charged. End of the day Bob's wire is "officially" credited - a $10.00 fee is charged for receiving the wire. (No, I'm not kidding) Bob's bank credits the $1000.00 of in state checks on Wednesday Finally, on Friday, Bob's out of state checks are deposited. Bob will likely be liable for $50.00-$75.00 fees for each of his bounced checks as vendors will probably charge hefty fees. Telecheck will have Bob on the 10 most wanted list for $350.00 in bounced checks. Bob's check writing ability is about nil in D.C. for the month it will take him to clear it up. Bob gets a mailing a week later telling him of the advantages of his bank's newest "overdraft insurance" program. $150 a year. Bob, for what would literally be a series of very responsible transactions, is looking at over $215.00 in bank fees, and at least $150 in bounced check fees from vendors because of violation of technical rules the bank has designed to cause fees to be charged. - - - E-Cash I cannot believe that e-cash won't be able to solve some of these problems, and I hope it will limit its own fees to usage. To me this is a classic argument for small house e-cash shops. Citibank and Mastercard are going to fight for their fees. -----BEGIN PGP SIGNATURE----- Version: 2.6.2 iQEVAwUBMClJUS1onm9OaF05AQEhugf/T2FquzHdEhHp8dQI5FRYcuayTusig1F3 pHejUdry84F1MqLArSZukVGxEWtZVR0qh2xq4AiN/UwlW9ZKasFdbPPGJtbD6gpO aALJIhQaYJSTQkW4fmieejhcNPMf7e59YaerOl83LkKS/+1tFi9ib1Xz2ZnmXlph 0mWuJjONzH45tPylyJy8fyB9nrpk5WDCAiLhUSxqHRdVmA9nq6uIIZbdmz7sEpLq 82cHyHXKeufGKGvx26R4z3lu0o5Ykd/dGAWADpJ6OT2bhlWFinApF/HMJAA9mLvi w70StZZL/94ncQQWF7LU5vMhGu7/5WNsrpRTzZXG5A0EfFL0ZAdYPw== =ew58 -----END PGP SIGNATURE----- 00B9289C28DC0E55 nemo repente fuit turpissimus - potestas scientiae in usu est E16D5378B81E1C96 quaere verum ad infinitum, loquitur sub rosa - wichtig! *New Key Information* - Finger for key revocation and latest key update.

"S1" encryption system (was: this looked like it might be interesting)
by Hal 17 Dec '03

17 Dec '03

I suppose the unstated implication is that this might be Skipjack. I have looked at the program a bit and have a few observations: There is an obvious typo in the "g" function, whose first parameter should be 0 or 1, but which tests it for 0, 1, or 2. This suggests an amateur effort. The coding style in general suggests a lack of familiarity with C (absence of "for" loops, with equivalent "while" loops substituted). The program appears to be based on a hardware-based description of the algorithm, judging from comments and style. The algorithm uses two fixed arrays F and G. Comments indicate that F was designed as four independent arrays F0, F1, F2, and F3. These are suposed to be non-linear. Each takes 8 bits in and 8 bits out. G is two arrays, each 8 bits in and 1 bit out. The comments indicate that it is supposed to be "pseudo-linear". G1 is the odd parity function. G0[i] is 0 0 1 1 0 1 1 0 0 1 repeated over and over. This is unusual because it is period 10 (the second 5 bits are the inverse of the first 5). I don't know whether there would be a more concise algorithmic representation of G0. Key size is 80 bits. The program implements the ability to hold 5 keys at once. Block size is 64 bits. The keys are expanded internally into a large array. I haven't looked at the key scheduling in detail. The encrypt and decrypt block functions have fixed xor's applied to the 64 bits of input and output. This appears to be cryptographically useless (or at least not very useful), similar to the initial permutation in DES. It is curious that xor's are used here rather than a permutation. That may represent an attempt to design the cipher to run well in software. The encryption function itself is a modified Feistel type cipher, with the blocks broken into 8 pieces and xor'd with functions involving F, G, the key and other pieces in a reversable pattern. The loop iterates 32 times but only two of the 8 pieces are changed each iteration so each 8 bit piece actually gets modified only 8 times. The pattern is: piece 6 modified by pieces 4, 5, 2, 3 piece 7 modified by pieces 4, 5, 0, 1 piece 0 modified by pieces 6, 7, 4, 5 piece 1 modified by pieces 6, 7, 2, 3 piece 2 modified by pieces 0, 1, 6, 7 piece 3 modified by pieces 0, 1, 4, 5 piece 4 modified by pieces 2, 3, 0, 1 piece 5 modified by pieces 2, 3, 6, 7 repeated 8 times. Decryption goes in the inverse order as is typical of these ciphers. The key is basically 80 bits, however there is a function S1_create_key which pads it with 16 bits of 0 and then encrypts it with two overlapping encryptions using the all-zeros key. The resulting 96 bit key is then fed as input to S1_load_key which decrypts it and checks for the 0's to ensure validity. I am not much of a cryptanalyst, but from what I understand the overall security of a Feistel-type cipher like this depends a great deal on the structure of the F (and in this case G) boxes. I would not be at all qualified to analyze those. So potentially this may be a strong cipher or it may be weak. The actual implementation does as I remarked show some signs of amateur programming skills. In addition to the points mentioned it is curious that the G arrays are initialized with a list of 256 values rather than taking advantage of the apparent regularities noted.
