asciilifeform: 'sympathy', 'support', esp. of the usg-sponsored very tangible/financial variety is on tap, no questions asked. imagine if insurance worked this way - how many houses would still remain standing ?
asciilifeform: or more pertinent example, the fabricated mega-gang-rapes of recent history
asciilifeform: !s sistine chapel ceiling
asciilifeform: no prizes for guessing this.
asciilifeform: and the idiot parade quietly vanished
asciilifeform: iirc it ended with something like a confession from whoever saw it that 'noose' was no noose at all, but a piece of garbage the wind carried
asciilifeform: http://abcnews.go.com/US/story?id=3580350
asciilifeform: (5 or so yrs ago, there was 'mass indignation', hastily-cooked mea culpas from virtually all organizations in any way connected with the campus, demonstrations 'of support' for 'the victims' - after a shred of rope was allegedly found hanging on a tree branch.)
asciilifeform: the latest lulz from umd almost beats the noose incident.
asciilifeform: there was perhaps a few shredded flaps of still-chromosomally-passable tissue when i was a student there, a decade ago.
asciilifeform: mircea_popescu: american universities got cancer long ago ('60s) but now there is scarcely one detectable cell from the original patient at all, only tumour.
asciilifeform: part ii: http://www.president.umd.edu/statements/campus_message031715.cfm
asciilifeform picking self up from floor after http://www.umdrightnow.umd.edu/news/important-statement-president-wallace-loh
asciilifeform: and yes, ultimate kbd ought to be something you can use with your hands in a sack (of conductive cloth naturally.)
asciilifeform: fuck speaking
asciilifeform: ugh speaking
asciilifeform: gedankenexperiment to wake folks up that keyboard for secure work ought to be 1) yes, mechanical 2) physically smallest that one can abide
asciilifeform: l0l
asciilifeform: mircea_popescu: into air, sure. and it vibrates. and no two spykes same length
asciilifeform: the 'tin hat' was always especially funny to folks who actually know a little physics, because parabolic antenna focused on brain.
asciilifeform: mircea_popescu: spoke portrude from each key << manual typewriter. invitation for acoustic snoopery. (and camera - radiates.)
asciilifeform: photon
asciilifeform: mircea_popescu: faraday cage is not (if correctly constructed) a radiating element at all
asciilifeform: http://www.cs.gmu.edu/~zduric/cs803/Simmons.pdf << unrelated but interesting from historical standpoint re: usg and practical use of rsa
asciilifeform: shielding even a screen is nontrivial.
asciilifeform: (mice are easy - just pipe picture from the business end of standard optical mouse, hollowed out, into a remote cabinet to which its guts have been moved)
asciilifeform: i looked into keyboards made of optical fibres, and found none in commercial circulation. looked if anyone has admitted to experimenting with such, and found no credible data - but, interestingly, folks have built mice on this principle, for use inside mri scanners.
asciilifeform: mircea_popescu: those can be 'heard' for considerable distances by intercepting lcd feed
asciilifeform: (and it is also interesting to think about what actually happens on the mechanical contacts. 'key bounce' is not only an annoyance for engineers, but a gift to radiodiddlers, as each spring - and rubber domes not excepted - has characteristic wear)
asciilifeform: so yes
asciilifeform: the closing of the matrix circuits
asciilifeform: that was my thought
asciilifeform: aha
asciilifeform: mircea_popescu: if about hypothetical purpose-built jammer - keyboard scan matrix in particular is a moving target, as the frequency of the telltale signal will vary considerably depending on which key(s) are pressed
asciilifeform: mircea_popescu: if asking about the 'second kbd controller as jammer' - the small physical differences (esp. in the quartz oscillator) add up to a distinguishable 'fingerprint' which lets enemy pull a particular kbd signal out of a room full of'em
asciilifeform: ;;later tell mircea_popescu: nor is a conventional jammer practical, because pressing keys results in shift of frequency of harmonics. this appears to be one of those cases where not shitting on the floor is considerably easier than mopping it up...
asciilifeform: ;;later tell mircea_popescu: interesting tidbit from the vuagnoux & pasini paper (section 5.5) - the second-keyboard-as-jammer thing doesn't really work.
asciilifeform: mircea_popescu, others from last night's thread: http://lasec.epfl.ch/keyboard << oldie re: keyboard rf.
asciilifeform: l0l
asciilifeform: but certainly not in pocket.
asciilifeform: or, likely, in the room you're sitting in.
asciilifeform: and no longer fits in pocket.
asciilifeform: -actual- means auditable
asciilifeform: deliver what?
asciilifeform: 'fried ice'
asciilifeform: no shit
asciilifeform: but shows how much of a fuck was actually given
asciilifeform: not that it would have made a serious difference in the end -
asciilifeform: but - didn't.
asciilifeform: re: iPnohe bruteforcer - apple could have easily written 1) update counter 2) validate code instead of 1) validate code 2) update counter
asciilifeform: l0ltr0n
asciilifeform: mircea_popescu: someone signed you up as a gag ?
asciilifeform: 'What is surprising however is that this still works even with the “Erase data after 10 attempts” configuration setting enabled. Our initial analysis indicates that the IP Box is able to bypass this restriction by connecting directly to the iPhone’s power source and aggressively cutting the power after each failed PIN attempt, but before the attempt has been synchronized to flash memory.' << mega-l0l!
asciilifeform: mircea_popescu: do the links contained in the turd point to the genuine site ?
asciilifeform: mircea_popescu: sounds like forged headers (why would the actual 'bitstamp' spam ? wtf is the point)
asciilifeform: http://cryptome.org/2012-info/obama-moron/0021.htm << vintage rf lulz
asciilifeform: http://benkrasnow.blogspot.com/2011/03/diy-scanning-electron-microscope.html << unrelated
asciilifeform: though the 'how' is trivial.
asciilifeform recalls reading patents for fiber keyboards but never saw any hint of such a thing in production.
asciilifeform: not to same extent
asciilifeform: decimation: damnably poor idea - easy 'optical tempest' intercept if anyone can see your body move
asciilifeform: or, failing that, mechanical vibration (as in early 'spark gap' cad tablets of the '70s)
asciilifeform: to round out the keyboard thread, i am quite close to being convinced of the necessity of keyboard with optical fiber for mechanism
asciilifeform: any machine-controllable scanner with machine-readable output is a (very) poor man's spectrum analyzer.
asciilifeform wonders if -everybody- has this one
asciilifeform: 100
asciilifeform: (it's an ancient rs232-controlled scanner, and handheld antenna over 50ohm coax)
asciilifeform: decimation: what do you suppose i was using.
asciilifeform: i only have the equivalent of a 'copper toilet' here.
asciilifeform: decimation: the rf amp is the golden toilet
asciilifeform: decimation: yes but entirely useless for this application.
asciilifeform could probably achieve more with an actual spectrum analyzer, but would have to sell organs
asciilifeform: mircea_popescu: yes but to have precisely same radiating profile
asciilifeform: mircea_popescu: ideal materials for this artistic project is controller from identical kbd, with keyswitch faker attached
asciilifeform: likbez for ze n00bz
asciilifeform: to anyone who was awake in kindergarten
asciilifeform: which is entirely unsurprising
asciilifeform: the array itself appears to radiate also.
asciilifeform: decimation: not coming from the cable!
asciilifeform: http://www.dribin.org/dave/keyboard/one_html << likbez
asciilifeform: mircea_popescu: think, scan matrix
asciilifeform: decimation: more than willing
asciilifeform: decimation: scan matrix
asciilifeform: specifically keyboard microcontroller.
asciilifeform: mnope.
asciilifeform: .... and another harmonic
asciilifeform: ... aaaand another harmonic
asciilifeform: mircea_popescu: otherwise just atmospheric static uncorrelated with distance of antenna from device
asciilifeform: mircea_popescu: +5dB when key repeating
asciilifeform: i knew they are loud, did not know -how-
asciilifeform: it's an ordinary '80s ps/2 kbd.
asciilifeform is -not- happy with his discovery
asciilifeform found yet another harmonic
asciilifeform: how ?
asciilifeform: vs pb ?
asciilifeform: BingoBoingo: not in mud hut
asciilifeform: (shielded)
asciilifeform: not coming from the cable
asciilifeform was actually looking for precisely it, and found it
asciilifeform: fucktardation
