Urgent Letter from Zimbabwe
by Dr.Wilfred Mboyo 21 Nov '02

21 Nov '02

Sir, URGENT BUSINESS RELATIONSHIP Firstly, I have to introduce myself to you. My name is Dr Wilfred Mboyo from Zimbabwe. I was the chairman of contract review panel in my country before the problem of the land reform program. Before the escalation of the situation in Zimbabwe I recovered $16.8Million US dollars from over inflated contracts by some government officials. But I was a member of the opposition party the MDC(Movement for Democratic Change), and the ruling Party, (ZANU PF) has been against us. So I had to flee the country for a neighbouring African Country which I am currently residing. Before the escalation of the situation in Zimbabwe I had not reported The recovery of my findings to the panel. So this money was in my possession and I lodged it in a security company here in Africa and currently this money has been moved to their security branch in Europe. I have been trying to fly to Europe but it has been difficult for me to get a visa from Africa. So I want you to help me make claims of this fund($16.8m) in Europe as my beneficiary and transfer the money to your account or any account of your choice before I can get a visa to fly down. So that we can share this money. I have agreed to give you 10%,which would be ($1.6Million dollars) of this Money for your assistance, and 85% would be mine and the other 5% would be set aside for any expenses that we may incure during the course of this transaction. And my 85% would be invested in your country in any profitable business propossed by you. We have never met, but I want to trust you and please do not let me down when this fund finally gets into your account. Please if you are interested, get to me through the email address below to enable me feed you with more details and all necessary documentations. Please treat this as confidential. ( mboyo2000(a)post.com or mboyo2001(a)email.com ) Regards, Dr.Wilfred Mboyo NOTE: In the event of your inability to handle this transaction please inform me so that i can look for another reliable person who can assist me.

Don't even bother trying to destroy the original. Chances are they will make a backup of everything before attempting anything. And destroying something is likely to be very obvious, and very damning. Best bet is to hide a second thing, which is kind of incriminating, but not much. And hide it less well that the real thing. People who think they understood the trick won't look any further, because they think they understood it. So, be sure to wail and complain when they discover the fake data, and not bear a knowing smile :) -- Vincent Penquerc'h

Not possible in the real world - you will only be reading from the message to create the "decoded" image, not overwriting it (under any circumstances) if the system required a overwritable message, then it both wouldn't work with most email software, and would be presented with a *copy* of the email by any attacker anyhow. Replaying and/or re-downloading email is trivial. Systems such as Disappearing Inc are good examples of this sort of snakeoil though - attempts to make email "expire" that can be broken by replacing the official executable with one that caches the keys.

However, if you are in a volley line and waiting for the last man to reload before firing a volley, that's a lifetime. Remember, you are standing up to reload! Putting a few men armed with rifles in a line of musketmen, they would seem useless, or worse, a liability. Before I get flamed about those figures, may I point out that modern black powder flintlock rifle shooters can and do shoot about one round a minute, without trying to fire fast - a hotspot on the barrel can cause the powder to cookoff unexpectedly, so they service the bore and touch hole between shots, which slows them; but this isn't so important on the battlefield when risks can be taken. It is said that Simon Kenton could reload his Kentucky rifle in 12 seconds. The world record Springfield reload is about 6.5 seconds, a Brown Bess will take a bit longer than a Springfield. At first glance the rifle was a better infantry weapon, but pitched battles at 300 yards just didn't happen - and smoke obscuring the battlefield made aimed shots difficult after a few volleys. Muskets weren't usually aimed, just pointed in the right direction - musketmen were sometimes told to close their eyes when firing to prevent injury from pan flash. In volley fire it isn't really possible to aim - for aimed fire you need to fire when the rifleman is ready, not on command. The superior accuracy of a rifle is no use if you can't or don't aim it. The time taken to aim also slows the rate of fire over an unaimed weapon. Another problem was that early rifles weren't optimised for battle or use in an army. It was often difficult starting the ball down the barrel, which can slow reload time - there's a tool to do it, and you then use the ramrod, but if the rifle/ball/patch combination is right you can start the ball by hitting it with the ball of your hand, and the ramming can be quite quick. Rifles were seldom fitted with bayonets, important to the tactics used at the time - fire a volley or two, then a bayonet charge while your opponents are reloading. They were also too fragile to use as a close quarter club. Rifles weren't standardised either, so ammunition and parts couldn't be shared and the riflemen had to cast/roll their own balls. Rifle balls need to be more accurate than musket balls. Rifles take more training to use as well. But I think the main reason that rifles didn't play a bigger part, apart from the usual military inertia (google Ferguson rifle for a British example of this), was the simple lack of rifles, and their cost. Many men fighting in the Revolutionary War didn't have any firearms at all. -- Peter Fairbrother

Would it be difficult? Yes it exists. It's called deniable encryption. Two-level deniable encryption is not hard, but it usually involves increases in data size. There is some stuff about this in Crypto and Eurocrypt reports. Steganography and steganogaphic filing systems can do something similar, but the increase in message size tends to be larger. I am developing a form of deniable encryption (as part of m-o-o-t) that works slightly differently and does not involve message-size increases - in fact it it decreases message size. It's grammer-based and works a bit like this: A sentence is parsed, and eg a noun is encoded as a number relating to one of a publicly shared dictionary of nouns. This number is then encrypted. Decrypting with a random key will give a noun in that position in the sentence in all possible decryptions, and a good proportion of all randomly keyed decryptions will apparently make sense. There is a lot more involved, so eg both parties can give out the same false key, and so eg the same nouns used more than once in a message will decrypt to identical nouns in decryptions, as well as notions of closeness in the words used in a typical message, but I have done both the theoretical unicity calculations and some practical tests, and it works for email-length messages. The main implementation problems I have are coding time and that the only parser that works well enough is proprietary. If anyone else is working on something similar I would like to know. I'm probably not a cypherpunk, more a privacy avocate, but I do write code. :) -- Peter Fairbrother
