"The GUNMAN project had a major impact on the intelligence community as a whole. It brought about a greater understanding of the thinking and operations in a totalitarian society. The community became more aware of the hostile electronic threat against the U.S. As <redacted> explained, "If any other agency such as CIA or the State Department had discovered the bug, this change would not have occurred because they would not have publicized the incident." NSA, however, briefed all levels of government to warn them of the danger. NSA was not out to assess blame; it took the problem-solving approach." (p. 17)
The word "totalitarian" is hyphenated, to make the line justified. Anyone else try to search for the phrase with a Ctrl-F, come up with zero, and jump to the conclusion that the spooks had redacted the document?
I should perhaps look into having my paranoia treated.
Just think: if everybody posted article snippets with no commentary, we could crowdsource the entire article being redundantly posted piecemeal to HN and nobody would need to click through to the article at all.
I was glad to learn that "The Thing" was apparently designed by Léon Theremin who invented in 1928 (!) the famous "electronic musical instrument controlled without physical contact by the performer."
For those too paranoid to open a .PDF from the NSA, several solid parts in the typewriter were replaced by solid-looking parts with embedded circuits and altered magnetic characteristics.
These circuits magnetically detected the motion of the arms that carried and moved the character ball. So non-printing keystrokes, like space, tab, and backspace, and the character that did not rotate the ball, '-', were not detectable. The circuits had a tiny buffer, so would transmit the detected characters as they were being typed. Early models used batteries. Later bugs diverted some of the AC mains power from the typewriter.
It is likely that a relay antenna was employed to increase the detection range of the transmitted signals, which used the same frequencies as local television broadcasts.
That's really about it. The bugs were largely undetectable without x-raying every single part in the typewriter, which is how they were eventually found.
(a) It's from their museum facility (if you ever get the chance to visit the National Cryptologic Museum in Maryland TAKE IT TAKE IT TAKE IT)[1], not the NSA itself.
(b) It's a scan of a 30-year-old report on a completed project, redacted heavily. Nothing more.
(c) If they want your inside leg measurement they've got better ways to find it without feeding you a PDF they overtly created.
[1] Where else will you find a teaching exhibit for visiting schoolkids that lets them cypher a message on a no-shit four rotor WW2 German Enigma machine, hand it to a friend, and watch them decrypt it on another Engima machine at the other side of the room? (Hint: valuable museum pieces.) Also, working (or at least blinkenlights powered up) exhibits like a CM1 Connection Machine and a Cray X-MP, and a history of their amazing linguistics branch[2] ...
[2] Who have the world's largest collection of bible translations. Want to know why? It's worth your while to pay them a visit.
Seconded. I went midweek around noon and it was pretty quiet so I got a personal 90 minute tour by an NSA retiree. He was very knowledgeable about crypto history, esp. as used in the cold war and WWII. They had Turing's "bombe", multiple Enigma variants, many lesser-known crypto machines, historic correspondence, a Cray YMP, codetalkers exhibit, spy satellites, and tons of other good stuff. Everything is free - except merchandise in the gift shop, which is also pretty unique.
I'd wager a guess that [2] was necessary for messages using it as a code, e.g., page number+word number, or page number and then the Nth word or letter.
The real answer is, the NSA is all about communications -- which isn't just electronics: it includes a huge element of linguistics.
The Bible angle: when a new tribe or culture is contacted, the very first thing that happens is that Christian missionaries get all excited and do their best to go there to spread the gospel. To do this, they have to learn the language sufficiently well to translate the Bible. So you've got this one text (with a quantifiably-variant or de-facto invariant baseline) that gets translated into every language on the planet as fast as is humanly possible after that language is discovered. It's a Rosetta stone.
I forget the number that was given for how many different-language Bibles the NSA has in their library, but it was impressive -- something over 900 languages.
(a) I wish I could but I doubt I ever will. I've heard so much bad stuff about US border guards being annoying and transiting through the US being slow and painful that I won't even use a US hub anymore.
(b) Cool I guess I can't know if this is true without opening it though? This is partly the fault of the pdf spec itself. Maybe a more transparent document format would help (does that even exist)?.
(c) I suspect that they already have them.
Furthermore. I actually really want to read it. I'd really like to trust the NSA. However, their record is not good on being trustworthy.
I am aware that the pdf specific is open. However pdf does a lot of things and is somewhat complex. I argue more than is needed for transmitting documents. Can you personally verify that a given pdf does nothing malicious?
Can you personally verify that a given jpeg does nothing malicious? Same thing, you trust (or not) your reader and its parser and hope it doesn't have any remote code execution vulnerability. Or you stop reading PDF files and stop viewing images.
If you are that paranoid, then you shouldn't open any pdf that you find on the internet. The NSA has the ability to proxy any file you download and inject anything they want.
