| kanzure | hi Daeken | 09:55 |
| kanzure | Daeken: my python talks to the usb/hdi controller for the bluetooth device (which communicates data from the headset) | 09:55 |
| kanzure | however, there are ways to use the library/sdk-- but i haven't tried anything on that route yet | 09:56 |
| Daeken | kanzure: ah, so you deal with the encryption and such directly? | 09:56 |
| kanzure | i sent back my emotiv to a friend (the original owner) recently but i recorded some raw data streams so presumably i can hook that back up and then one day fiddle with the sdk or something (dunno) | 09:56 |
| kanzure | right | 09:56 |
| Daeken | is your source public, by any chance? i'm currently hacking on it from deadlistings of assembly, with no hardware to play around with haha | 09:57 |
| kanzure | yes i have it around here somewhere. uhh.. /me finds | 09:57 |

| Daeken | did you ever narrow down what the AES key is? i can see where the rijndael initialization stuff takes place, so i should be able to pull the key out fairly easily. | 10:09 |
| Daeken | can't wait to get one of these headsets and hack the hell out of it :P | 10:09 |
| kanzure | rijndael? | 10:10 |
| Daeken | AES | 10:10 |
| kanzure | i don't have my notes on me (obviously) but i did narrow down a few things.. i didn't get it exactly though | 10:10 |
| kanzure | how is rijndael related to AES? | 10:10 |

| Daeken | rijndael is the actual algorithm name that became the advanced encryption standard | 10:11 |
| kanzure | oh | 10:11 |
| Daeken | i just call it that out of habit haha | 10:11 |
| -!- QuantumG [~qg@rtfm.insomnia.org] has quit [Ping timeout: 240 seconds] | 10:11 | |
| Daeken | i found the md5 init/update/finalize methods, rijndael initialization/encryption/decryption, and the crypto++ code that ties it all together. it's just a pain in the ass to figure out where things are called from, due to it being C++. vtables make my life hell :P | 10:12 |
| * kanzure nods | 10:12 | |
| kanzure | yes i found crypto++ too | 10:12 |
| Daeken | but if i break on the initialization stuff, i'll be able to see the key in memory. should be pretty straightforward | 10:12 |
| kanzure | i mean, signs that they used it | 10:13 |
| kanzure | ah you actually have windows? | 10:13 |
| kanzure | that probably makes the task a little bit easier | 10:13 |
| Daeken | yea, i just want to be able to access the raw EEG stuff from wherever i feel like | 10:13 |
| kanzure | me too | 10:14 |
| kanzure | so, one of those .py files will help you do raw recording (at least on linux) of the data | 10:14 |
| kanzure | but it's still encrypted | 10:14 |
| -!- QuantumG [~qg@rtfm.insomnia.org] has joined #hplusroadmap | 10:14 | |
| kanzure | and i'm not sure how i would decrypt it anyway.. i guess at the start of each frame or something? | 10:14 |
| kanzure | i don't know :) | 10:14 |
| kanzure | jrayhawk: what's wrong with my .htaccess in /srv/www/diyhpl.us/irc/? | 10:14 |
| kanzure | hi QuantumG. did you see my linkdump earlier today about copenhagen space? | 10:15 |
| Daeken | well, a few questions: 1) is the length of the data a multiple of 16? 2) does the header look like it's not particularly random? | 10:15 |
| kanzure | QuantumG: http://gnusha.org/logs/2010-08-23.log | 10:16 |
| Daeken | my guess would be that the whole hid packet is probably encrypted, in which case the data should be a multiple of 16. | 10:16 |
| Daeken | and it should look decently random, although i believe they're using AES in ECB mode, so it won't be crazy | 10:17 |
| kanzure | 1) each "read" from the usb device was about 30 to 52 characters long | 10:17 |
| kanzure | check out the .dat file for some raw reads | 10:17 |
| Daeken | ahhh, ok | 10:17 |
| Daeken | sweet. | 10:17 |
| kanzure | i was doing this: hid_interrupt_read(interface0, 0x82, 32, 4) | 10:17 |
| kanzure | the parameters are: hidif, ep, bytes, size, timeout | 10:18 |
| kanzure | hrm i wonder if i arbitrarily chose 32 | 10:18 |
| Daeken | wow, ok, yea, that's ECB :P | 10:19 |
| kanzure | emacs code browser? | 10:19 |
| Daeken | lots of patterned data in the .dat | 10:20 |
| Daeken | electronic codebook -- each block gets encrypted on its own. you'll see lots of common data | 10:20 |
| kanzure | but i'm not sure if i was just dicking around and- due to my own error- the length of the lines are arbitrary and not relate to anything going on in the devices | 10:21 |
| kanzure | btw it looks like emotiv.py uses the python "usb" library which should be fairly standard across platforms.. so if you actually have an emotiv.. | 10:21 |
| kanzure | oh man. i so wish that there's a random line in the .dat file-- anything, really, like a quote from timothy leary, a quote from adolf hitler, something. | 10:22 |
| Daeken | yea, but it does look like they're encrypted end-to-end. can't see much more than that, but that's ok | 10:22 |
| kanzure | "THINK4URSELF. QUESTION ATHRTY" dunno how to get the size down small enough :P | 10:23 |
| Daeken | haha | 10:23 |
| kanzure | before i forget, there's been a number of others who have come in here asking about this | 10:25 |
| kanzure | at the very least: thesnark (michael grube), masked | 10:26 |
| kanzure | hah! 20:41 < kanzure> how stupid. it blinks when the buffer is read from on the dongle | 10:26 |
| kanzure | http://gnusha.org/logs/2010-03-05.log | 10:26 |
| Daeken | ah, cool | 10:26 |
| kanzure | also some other stuff about the encryption here: | 10:27 |
| kanzure | http://gnusha.org/logs/2010-07-08.log | 10:27 |
| kanzure | the discussion with masked: http://gnusha.org/logs/2010-07-18.log | 10:28 |
| kanzure | thesnark has been in here a number of times to mention his openeeg/emotiv-epoc hacking projects | 10:29 |
| kanzure | one is to increase the number of channels (up to 32) of an openeeg device | 10:29 |
| Daeken | oh wait, he's the dude behind openeeg, or just hacks on it? | 10:29 |
| kanzure | the other is replacing the digital signal processor in an emotiv (he suspects it's what's doing the encryption) | 10:29 |
| kanzure | hacks on it | 10:29 |
| Daeken | ahh | 10:29 |
| kanzure | speaking of which, where are either of them? | 10:30 |
| Daeken | my main concern is publishing code to hack the emotiv in various ways, then them updating the firmware and making it all null and void :P | 10:30 |
| Daeken | so for the community's sake, i'm hoping it's a PITA for them to roll out an update ;) | 10:31 |
| kanzure | honestly the software that i have seen from them so far doesn't make me think they have the most stellar software team | 10:31 |
| kanzure | it looks like it might even be an outsourcing job (which is weird, since they are already in the philippines) | 10:31 |
| kanzure | like to a .NET shop or something | 10:31 |
| Daeken | indeed | 10:32 |
| Daeken | hmm.... >:) | 10:32 |
| kanzure | worst case scenario is they hire whoever hacks it? but that's not their style | 10:32 |
| Daeken | i just had a sick idea. i can hook the HID api, emulate the presense of an emotiv device, then grab the key out of the AES initialization when it connects/communicates. | 10:33 |
| kanzure | why do you need HID for that | 10:33 |
| kanzure | i don't think it communicates the key to the device ;) | 10:33 |
| Daeken | just to make it think there's an emotiv device there, so it initializes the crypto | 10:33 |
| kanzure | QuantumG: ffs, isn't this your job? | 10:34 |
| Daeken | btw, how the hell have i not heard of this channel before? haha | 10:35 |

| masked | oh yer lol i think thats how i found you in the first place! | 10:44 |
| Daeken | so, i should be able to pull the key out of the edk Real Soon Now (TM). from there, it shouldn't be terribly difficult to figure out what exactly is going on... in theory, i should be able to emulate a headset, which will let me figure out the protocol | 10:45 |

| Daeken | i have a feeling that there's no key exchange wizardry or anything of the like going on... from what i'm seeing, they just don't really care about locking down the device. if they did, they would've at least changed the aes s-box or somesuch :P | 10:46 |
| -!- patrik is now known as Guest88990 | 10:46 | |
| Daeken | but when i see standard s-boxes, no obfuscation, no packing... it makes me think that it's all straightforward | 10:47 |
| kanzure | "Well... we're collecting beta testers and there's a version already out there for the Developer SDK. Our current problem relates to video card driver versions in different Linux builds." | 10:47 |
| kanzure | ^ i think you're doing it wrong if your eeg device driver depends on anything related to video cards | 10:47 |

| masked | at least he appears human | 10:50 |
| Daeken | would you be willing, at some point, to run a test script to see if the crypto stuff actually works, once i grab the key? it's all well and good to emulate the other side, but making sure it works with the real hardware would be cool | 10:50 |
| masked | sure | 10:51 |
| Daeken | great | 10:51 |
| kanzure | Daeken: i thought you had one too? | 10:51 |
| Daeken | kanzure: not yet -- totally working off the edk binaries right now haha | 10:51 |
| masked | when i actually get a chance may not be straight away, but i can do it | 10:51 |
| Daeken | yea, that's cool | 10:52 |
| kanzure | oh mighty saurik, please bestow upon us mumble mumble mumble | 10:53 |
| Daeken | my plan is to hook the hid/siusbxp imports from the edk and make it think that i have a device connected... from there, i can break on the AES initialization to get the key(s), then emulate the behavior of the headset. if the crypto stuff works, it should be possible to feed the EDK any data i feel like, from my emulated headset | 10:53 |
| kanzure | btw take a stroll through the symbols in the dll files. it's fairly revealing of how "sophisticated" their signal processing is (some simple gaussians and such) | 10:54 |
| masked | plug some tcp/ip andi can feed your edk :P | 10:54 |
| Daeken | masked: ahhh... damn, that's a fine idea. | 10:55 |
| masked | yeh i had a feeling it was not as advanced as they made it out to be! | 10:55 |
| kanzure | well, they are just symbol names of course :) but heck, they are using .NET | 10:56 |
| Daeken | what exactly are they using .NET for? i've only looked at edk.dll, thus far. | 10:57 |
| Daeken | well, and the .NET wrapper they ship with it | 10:57 |
| kanzure | wow did i honestly forget to make a .iso of the CD i shipped back? | 10:59 |
| Daeken | any idea what the siusbxp stuff is used for? i'm wondering if it's for device initialization or somesuch, before the HID stuff kicks in. | 11:00 |

| kanzure | masked: what? | 11:00 |

| kanzure | when i was shipping it back to whoever, they asked if i wanted to insure it and for how much | 11:01 |
| kanzure | so i looked it up and was really disappointed with how cheap it is | 11:01 |
| kanzure | i mean, i thought this was a >$500 product | 11:02 |

| Daeken | sweet... groundwork is laid for emulating the epoc. just going to have to talk to a socket and feed it raw data... so in theory, you'll be able to control emotiv apps from the other side of the world :P | 11:59 |

| Utopiah | Daeken: with what app are you interfacing it with? | 12:02 |
| Daeken | Utopiah: none, at the moment. i'm just writing a general set of hooks for edk, to capture the accesses to HID/siusbxp/setupapi. from there, i can attach it to any emotiv app, and a little python script i'm writing to emulate the headset... from there, getting the crypto all figured out should be easy, and then i can reverse the protocol (trivial) | 12:04 |
| Utopiah | ok, are you documenting the process on your website? checked http://openvibe.inria.fr ? | 12:05 |
| Daeken | not documenting the process, but i'll be releasing all the code and writing a blog post up once i'm done | 12:06 |
| Daeken | and no, haven't seen it | 12:06 |
| Daeken | oh cool. hmm | 12:07 |
| Daeken | once i document the protocol and crypto, it shouldn't be hard for someone to implement an openvibe acquisition module for the epoc | 12:07 |
| Daeken | oh nice, you can actually feed it data over the network | 12:08 |
| Daeken | i'll have to hack something together for that. thanks for the info | 12:08 |

| kanzure | but other than that, everything else was great | 15:29 |
| kanzure | i think even a team of 6 people would be large (for programming) | 15:29 |

| ybit | o noes | 18:08 |
| ybit | well, i will have to find someone with access willing to setup a proxy again | 18:08 |
| ybit | i've been spoiled and i can't go back | 18:08 |
| ybit | i wonder why kenneth hayworth uses a fib instead of an sem when taking images of the brain | 18:09 |
| kanzure | because it's what his professor has | 18:09 |

| ybit | kanzure: you're in austin, right? | 18:14 |
| ybit | why can't you just walk down to the ADL and jank the computer? :) | 18:14 |

| ybit | i've a nice .45 caliber pistol if you need an accomplice ;) | 18:17 |
| kanzure | wow this actually works as advertized | 18:18 |
| kanzure | http://beziereditor.sourceforge.net/screenshots.php | 18:18 |
| kanzure | ybit: because the computer is bolted to the desk | 18:19 |
| katsmeow-afk | can't you use a new desk too? | 18:20 |
| kanzure | this is quickly becoming dangerously similar to stealing | 18:22 |
| kanzure | i'm no hans reiser | 18:22 |
| ybit | i've a ski mask if you need one | 18:22 |
| kanzure | aww shucks | 18:22 |
| genehacker | WTF are you doing? | 18:22 |
| * kanzure wonders how to draw perfect semi-circles with bezier curves | 18:22 | |
| kanzure | for some value of perfect | 18:23 |
| genehacker | bezier curves don't like to circle | 18:23 |
| genehacker | use a b-spline | 18:23 |
| kanzure | that's why i said semi :) it's an arc | 18:23 |
| genehacker | I need to read more about b-splines | 18:23 |
| genehacker | why? | 18:23 |
| kanzure | because my python/CAD thing needs a visualizer with it | 18:24 |
| kanzure | and before i can render cylinders and other primitives i need to be able to visualize arcs and circles (so that they can be extruded) | 18:24 |
| kanzure | i'd like to have a copy of one of the winners from this: http://www.cs.caltech.edu/courses/cs171/assignments/hw5.shtml | 18:25 |
| kanzure | it's a glu/glut nurbs editor homework assignment | 18:25 |
| QuantumG | what happened to the glu nurbs code you found? not good enough? | 18:26 |
| kanzure | the reason i was looking into the glu nurbs stuff was two fold | 18:27 |
| kanzure | (1) for an actual rendering mechanism (check) | 18:27 |
| kanzure | (2) so that i can make an editor to rapidly test out different nurbs before i add it into step.py | 18:27 |
| QuantumG | isn't "editing nurbs" just dragging around control points? | 18:28 |
| kanzure | no, suppose i have a class Nurb and can initialize it with different control points, knots, etc. | 18:29 |
| kanzure | so the idea is to be able to see what the curve or surface that i handwave into existence | 18:29 |
| kanzure | *into existence looks like | 18:29 |
| kanzure | genehacker: you're right, i don't know what i was thinking (i want a spline editor not a bezier curve editor) | 18:32 |
| * katsmeow-afk breathes a sigh or relief | 18:33 | |
| kanzure | ? | 18:33 |
| jrayhawk | so what's stopping you from removing the bolts and/or fixing the server | 18:33 |
| kanzure | jrayhawk: it's technically matt's server | 18:33 |
| katsmeow-afk | well, like genehacker, i didn't know what you were meaning either | 18:33 |
| kanzure | and they issued a dmca takedown notice, the server went up in flames, and i think matt might be mad at me about that | 18:33 |
| kanzure | so stealing the computer might be misconstrued as stealing | 18:33 |
| bkero | lol | 18:34 |
| jrayhawk | perhaps you should ask him what the best way to get your data back would be | 18:34 |
| kanzure | he's in germany and is using that as an excuse for not dealing with the situation | 18:34 |
| genehacker | so basically the servers have a specially security system on them that will set off all bells and whistles if you try to steal it | 18:34 |
| katsmeow-afk | usb drive | 18:34 |
| kanzure | katsmeow-afk: the power supply is dead | 18:34 |
| JayDugger | Can you open the case? | 18:34 |
| genehacker | sensor there | 18:34 |
| kanzure | no, that's where one of the "alarm implants" is located (physically) | 18:34 |
| kanzure | the alarm riggup is actually kind of hilarious | 18:35 |
| kanzure | fenn claims it encourages would be thieves to just steal the monitor AND the computer simultaneously | 18:35 |
| katsmeow-afk | pull a removeable hd, power it thru that plug? | 18:35 |
| genehacker | the system was designed by dell for usage in indian slums | 18:35 |
| fenn | it encourages bringing a chisel to remove the glued-on piece | 18:35 |
| QuantumG | http://forums.somethingawful.com/showthread.php?threadid=3271649&userid=49790 <- did I mention this thread? it's awesome. | 18:35 |

| genehacker | danish rocket thread? | 18:35 |
| kanzure | QuantumG: i linked to that earlier today :P look at my link dump (it was meant for you) | 18:36 |

| kanzure | genehacker: there's lots of wonderful things out of SA | 18:36 |
| QuantumG | sorting by that guy's userid really helps to make the thread readable | 18:36 |
| kanzure | like 4chan and blackjack | 18:36 |
| genehacker | blackjack? | 18:36 |
| kanzure | it's an exaggerated claim | 18:37 |

| kanzure | i hear that the guy commutes to work in a submarine | 18:38 |
| genehacker | holy fuck that is awesome | 18:38 |
| QuantumG | yeah, there's pictures on the mini-sub towing the platform at the end of the thread. | 18:38 |
| QuantumG | s/on/of/ | 18:39 |
| genehacker | that's a pretty serious sub | 18:39 |
| genehacker | I wonder how long it can stay under | 18:39 |
| QuantumG | I think it's more a u-boat than a proper mini-sub | 18:39 |
| jrayhawk | What's the alarm rigged up to do? | 18:40 |
| kanzure | hey that's a god question | 18:40 |
| kanzure | *good | 18:40 |
| kanzure | i think it's actually just a lock | 18:40 |
| genehacker | to beep, it instantly calls the police | 18:40 |
| kanzure | no, i don't think so | 18:40 |
| kanzure | matt got it off the shelf from best buy or something | 18:41 |
| kanzure | it can't be that sophisticated | 18:41 |
| genehacker | haven't you ever been in the lab when the alarm goes off and the ninja team shows up? | 18:41 |
| kanzure | i was when there was some seriously suited up SWAT teams running around with semi-automatic rifles | 18:42 |
| fenn | "ATmega168 works fine at 90K, but green LEDs become orange. Who knew? | 18:42 |
| fenn | fully automatic rifles | 18:43 |
| genehacker | I thought they just stopped working at 90 k | 18:43 |
| genehacker | semiconductors are supposed to become nonconductors at that temperature or something | 18:43 |
| kanzure | they were fully automatic? | 18:45 |
