1 00:00:00,440 --> 00:00:02,780 So there we are again. 2 00:00:05,160 --> 00:00:07,880 And as you can see on the screen. 3 00:00:08,500 --> 00:00:12,020 We're at DEF CON and this is the Monero village. 4 00:00:12,520 --> 00:00:16,800 And today we're talking about the intervillage badge. 5 00:00:17,660 --> 00:00:19,900 We're talking about that thing. 6 00:00:20,960 --> 00:00:21,560 Right. 7 00:00:21,560 --> 00:00:24,320 Oh, what happened to. 8 00:00:24,320 --> 00:00:27,100 Did you see that strange pixelation. 9 00:00:27,480 --> 00:00:29,080 Okay, sorry. 10 00:00:29,080 --> 00:00:37,920 Anyway, so my name is Michael, and I'll be your speaking guide through getting started with the badge. 11 00:00:37,920 --> 00:00:48,360 Today, we have one hour, and I'm missing some information some content that I can't find so we may have to postpone part of this until tomorrow. 12 00:00:48,500 --> 00:00:51,780 Let me show you what we're doing tomorrow, and the next day. 13 00:00:51,780 --> 00:00:54,620 This is Friday, the first day of DEF CON. 14 00:00:54,620 --> 00:00:59,760 And tomorrow, Saturday, Sunday, we have excellent speeches. 15 00:00:59,760 --> 00:01:03,320 I think Daniel Kim is coming back for another speech. 16 00:01:03,320 --> 00:01:06,700 I really recommend that it's really good speaker. 17 00:01:09,340 --> 00:01:14,320 And so let's check out what we have done so far. 18 00:01:18,480 --> 00:01:24,600 These are very elegant, modern slide deck system. 19 00:01:24,620 --> 00:01:27,620 This year DEF CON is on a retro trip. 20 00:01:27,620 --> 00:01:31,280 If you've looked at the fonts, colors, and theme. 21 00:01:31,460 --> 00:01:34,460 So, we're going to do some slides on paper. 22 00:01:34,460 --> 00:01:36,140 Is that okay with you. 23 00:01:36,300 --> 00:01:37,380 Yeah. 24 00:01:37,820 --> 00:01:39,100 Okay. 25 00:01:39,980 --> 00:01:56,050 So, we just finished this presentation, which was this year's badge where we talked most about construction, do it yourself, deconstruction, putting it together, assembly. 26 00:01:57,510 --> 00:02:09,100 This one is called Getting Started with the InterVillage badge, obviously. 27 00:02:09,100 --> 00:02:10,700 So that's what we're focusing on. 28 00:02:10,700 --> 00:02:13,160 There's lots of other devices I have. 29 00:02:13,160 --> 00:02:20,580 We'll get to that tomorrow in the office hours but things like the Monero Rising is available as well. 30 00:02:21,100 --> 00:02:26,440 And this is maybe useful just for the size comparison. 31 00:02:26,560 --> 00:02:31,280 In any case, I wanted to keep everything quite clear. 32 00:02:31,280 --> 00:02:38,400 Today is Friday, we covered the construction, I think you can review that if it's recorded. 33 00:02:38,420 --> 00:02:40,840 We're going to talk about getting started now. 34 00:02:40,840 --> 00:02:52,040 This is the first steps towards using the InterVillage badge in a useful, maybe even productive, hacky, fun way. 35 00:02:52,040 --> 00:02:54,360 Getting some value out of it by using it. 36 00:02:54,360 --> 00:02:57,380 That's what we're talking about today, the getting started. 37 00:02:58,680 --> 00:03:07,500 Tomorrow, Saturday, you can find in our schedule which is online, monerovillage.org. 38 00:03:08,120 --> 00:03:14,980 You can find that we have a badge clinic among a number of other very good presentations. 39 00:03:16,600 --> 00:03:19,180 Mine might not be too bad either, right? 40 00:03:19,180 --> 00:03:21,040 It's called the badge clinic. 41 00:03:21,320 --> 00:03:24,860 We're going to combine this with a new concept in Discord. 42 00:03:24,860 --> 00:03:29,600 We have a channel that's intended for use with office hours. 43 00:03:29,600 --> 00:03:35,720 So if we get lucky and people understand, then we'll have a bit more interaction. 44 00:03:35,720 --> 00:03:45,160 Hopefully we'll do some chatting at the same time as visual explanations with a document camera, close range circuit photos. 45 00:03:45,360 --> 00:03:51,440 And that will be tomorrow, Saturday, for the badge clinic, which is one hour long. 46 00:03:52,420 --> 00:04:09,340 During that badge clinic, we're going to do some impersonation, some kind of man-in-the-middle style attacks on our own devices, which is really similar to backing up our own data, right? 47 00:04:09,340 --> 00:04:18,220 If another person who doesn't have permission does these type of impersonation things to your devices and data, then it's called theft. 48 00:04:18,220 --> 00:04:30,320 But if you do it because you're backing up, what, your library card or doing things like that, well, that's just the utility of an NFC device, whatever it is, right? 49 00:04:30,320 --> 00:04:32,820 Your credit cards are NFC devices. 50 00:04:32,880 --> 00:04:34,940 Okay, we're not going to do financial. 51 00:04:34,940 --> 00:04:37,300 We're not going to copy credit cards. 52 00:04:38,420 --> 00:05:00,980 We probably will get to examine some NDEF records, which is the, it's not a file system, but it's something similar, how the data is organized piece by piece in the radio, the RFID, EEPROM, or erasable, programmable, read-only memory. 53 00:05:00,980 --> 00:05:02,940 So that's what we're going to do tomorrow. 54 00:05:02,940 --> 00:05:05,700 That's going to be a bit complex, a bit more advanced. 55 00:05:05,700 --> 00:05:12,840 But I do welcome you because an office hour badge clinic style presentation is for everybody. 56 00:05:12,840 --> 00:05:24,640 So if you're a beginner, if you're just getting started, if you have no intention of ever using, owning, having, constructing, holding a device, then maybe you're curious. 57 00:05:24,640 --> 00:05:28,360 Come by and talk about what you're interested in. 58 00:05:28,360 --> 00:05:30,320 On Sunday, we have a repeat. 59 00:05:31,540 --> 00:05:34,740 And maybe we'll try something like a free mic. 60 00:05:34,740 --> 00:05:37,000 I don't know if we can do that. 61 00:05:37,280 --> 00:05:45,460 On Discord you can, but it doesn't scale proportionately towards the tens of thousands that DEF CON is expecting. 62 00:05:45,460 --> 00:05:48,080 So that may work, may not. 63 00:05:48,840 --> 00:05:52,400 So this is our lineup for the different days. 64 00:05:52,400 --> 00:05:58,460 And right now we're doing a getting started presentation where we will take one of these badges. 65 00:06:00,600 --> 00:06:05,700 And, and we'll, we'll get familiar with it. 66 00:06:05,700 --> 00:06:09,820 We'll learn how to use it and see what its limits are. 67 00:06:10,740 --> 00:06:12,720 And we'll just start using it. 68 00:06:13,660 --> 00:06:18,040 So, I have some extra stuff over here as well. 69 00:06:18,040 --> 00:06:23,140 These are all NFC powered devices. 70 00:06:23,140 --> 00:06:26,760 They look like cards, but they're really electronics. 71 00:06:27,280 --> 00:06:28,660 I mean, I don't have to tell you that. 72 00:06:28,660 --> 00:06:38,900 Everyone knows that when there's this type of golden connector on a plastic card that there's really an integrated circuit of some kind, some sort inside. 73 00:06:40,260 --> 00:06:42,160 What else do I have. 74 00:06:42,160 --> 00:06:52,560 So this is, I maybe want to put my thumb over the, over the phone number. 75 00:06:52,580 --> 00:06:54,960 Right, it's probably too late. 76 00:06:55,080 --> 00:06:57,160 I don't really care but... 77 00:06:57,160 --> 00:06:59,460 So I'm going to keep it turned over. 78 00:07:00,120 --> 00:07:01,820 That was a faux pas. 79 00:07:02,060 --> 00:07:05,190 Anyway, so this is a YubiKey. 80 00:07:05,190 --> 00:07:16,270 And because this YubiKey has this little symbol, which if you can see, it's, it looks like a radio transmission symbol. 81 00:07:16,270 --> 00:07:16,770 Right. 82 00:07:16,770 --> 00:07:20,810 They don't all have radio transmitters inside them. 83 00:07:20,810 --> 00:07:31,390 In fact, lots of people prefer two factor authentication devices, which are unable to transmit radio, just for security purposes. 84 00:07:31,390 --> 00:07:42,490 This is the same reason someone, some prefer password wallets without Bluetooth connector connections. 85 00:07:42,650 --> 00:08:00,630 But if you want to experiment or if you're trusting of this technology of radio, then you can take a, then you can get a two factor authentication, which, which uses radio for its transmission. 86 00:08:00,630 --> 00:08:17,950 All of these different things are either using the same radio systems but not impersonate-able, or they are, and we'll get to those advanced attacks or uses, use cases and scenarios tomorrow. 87 00:08:17,950 --> 00:08:24,710 Just wanted to kind of introduce what type of devices we can work with. 88 00:08:26,250 --> 00:08:29,090 So let's go back to the badges. 89 00:08:29,090 --> 00:08:35,170 They're about the same size as last year's Monero Rising. 90 00:08:36,110 --> 00:08:50,670 There's a simple reason for that is that our robots, machines, and automated tools use up to 14 centimeters of width. 91 00:08:50,670 --> 00:08:53,770 So the two together are 14 centimeters. 92 00:08:54,890 --> 00:08:57,130 Small anecdote there. 93 00:08:57,130 --> 00:09:08,570 So we have black badges, we have green ones, we have orange ones, we have about five colors, in case you're wondering what these colors are, it's kind of difficult to see in the light. 94 00:09:08,650 --> 00:09:10,910 That's a green one, that's an orange one. 95 00:09:11,750 --> 00:09:18,570 And the first thing that we can talk about when we're getting started with these badges. 96 00:09:19,250 --> 00:09:22,810 Let me see if what my slide deck is showing me here. 97 00:09:23,090 --> 00:09:24,870 Here's some old stuff. 98 00:09:25,830 --> 00:09:27,750 We're not going to need that. 99 00:09:29,490 --> 00:09:45,630 All right, so because I failed very badly at figuring out screen casting, I'm not going to be able to use the computer which is capturing the video and multiplexing it with audio and everything else. 100 00:09:45,630 --> 00:09:48,650 I'm not going to be able to use that for the web browser. 101 00:09:48,650 --> 00:09:56,270 And for the NFC programmer, so we're going to do this here. 102 00:09:56,910 --> 00:09:58,190 Use a phone. 103 00:09:58,190 --> 00:09:59,370 How about that. 104 00:10:00,030 --> 00:10:10,450 Okay, so I'll give you a very fast demonstration since we're already 10 minutes in, of a typical use. 105 00:10:12,490 --> 00:10:17,830 So, because we go to the manual, we always read the manual first. 106 00:10:17,830 --> 00:10:19,410 What is that RTFM. 107 00:10:20,330 --> 00:10:31,330 Then, people who receive a fully loaded badge they get a color manual, and the others, you get a black and white one but they look the same. 108 00:10:32,250 --> 00:10:40,030 And I think they have this section right here, where it says, participate in the DC 28 DEFCON. 109 00:10:40,030 --> 00:10:45,170 That stands for DEFCON DC 28 village network stories. 110 00:10:45,190 --> 00:10:47,670 So we have two URLs there. 111 00:10:47,670 --> 00:10:51,030 I think two is a good number to start with. 112 00:10:51,030 --> 00:11:01,750 And they're in under development so that will be difficult to use but it's your and my responsibility to make this stuff work well. 113 00:11:01,750 --> 00:11:08,250 It's open source, it's a distributed use case and development model. 114 00:11:08,250 --> 00:11:17,370 So, so what's not right is to expect well, I'm sure that those other hackers are more competent they'll do the job for me. 115 00:11:17,370 --> 00:11:21,950 Now you need to get involved, make these things better than they already are. 116 00:11:21,950 --> 00:11:26,810 But what what can help is to simply recognize these two URLs. 117 00:11:26,810 --> 00:11:29,290 And we will go there right now. 118 00:11:29,670 --> 00:11:37,090 Because I'm not an expert with the rogues village game, which is this thing here for suits game. 119 00:11:37,590 --> 00:11:43,310 We may try it if we get time but I can't explain much, I'm going to have to research that more. 120 00:11:43,310 --> 00:11:49,030 And on Sunday, I may as well mention that in between. 121 00:11:49,030 --> 00:11:50,470 When is it. 122 00:11:50,470 --> 00:11:54,090 Before the Sunday badge clinic. 123 00:11:54,430 --> 00:11:58,870 We have a rogues village game slash inner village badge 124 00:12:02,050 --> 00:12:06,810 question answer session I'm not can't remember what the name is. 125 00:12:07,560 --> 00:12:14,090 But it's, it's at noontime on Sunday, noontime UTC minus seven that's Las Vegas time. 126 00:12:14,090 --> 00:12:26,170 So if you're interested in this, the, this, the game that they're developing that's what you want to watch is the Sunday presentation, and I even get permission to be a guest speaker. 127 00:12:26,630 --> 00:12:29,390 So, if you want to see me again. 128 00:12:30,030 --> 00:12:31,930 You've got to come back on Sunday. 129 00:12:32,430 --> 00:12:33,530 Let's see. 130 00:12:33,530 --> 00:12:37,670 So we're, because, because I'm kind of helping to develop this year. 131 00:12:37,670 --> 00:12:41,110 I'm just going to go right to the Bob right now, B.O.B. 132 00:12:41,330 --> 00:12:47,630 Bush of being is the code name for that might want to remember that we may have a pop quiz. 133 00:12:49,210 --> 00:12:50,670 So the B.O.B. 134 00:12:50,770 --> 00:12:52,230 Do you remember what B.O.B. 135 00:12:52,230 --> 00:12:53,270 stands for. 136 00:12:53,510 --> 00:12:55,670 Are you going to put push rewind. 137 00:12:56,370 --> 00:13:00,910 Alright, so let's open this up 138 00:13:04,100 --> 00:13:10,580 to, instead of www we'll go to B.O.B. 139 00:13:10,600 --> 00:13:12,620 Can you see that okay. 140 00:13:20,790 --> 00:13:22,170 There we have that. 141 00:13:23,850 --> 00:13:31,850 Not so familiar with this because we're just developing it at this moment. 142 00:13:32,150 --> 00:13:34,350 So if you go to the B.O.B. 143 00:13:34,350 --> 00:13:35,670 which is in the manual. 144 00:13:37,730 --> 00:13:39,550 You get this page. 145 00:13:40,350 --> 00:13:44,910 And that's a good way to get started right that's the name of this presentation getting started. 146 00:13:47,490 --> 00:13:50,610 What eventually we will be able to do with this. 147 00:13:50,790 --> 00:13:59,250 We have this working, but it's on a staging site, which doesn't have eye candy or CSS or, you know, styles. 148 00:13:59,410 --> 00:14:01,490 So what this does. 149 00:14:03,650 --> 00:14:05,910 Let me see if I can find it. 150 00:14:05,910 --> 00:14:07,930 Where is it. 151 00:14:07,970 --> 00:14:09,130 There it is. 152 00:14:09,130 --> 00:14:13,950 So what this does is it helps you onboard your badge device. 153 00:14:14,350 --> 00:14:21,430 Okay, so there's you've got these three buttons on here, you have different IDs and different data on them. 154 00:14:21,430 --> 00:14:26,350 And depending on your, your personal preferences. 155 00:14:26,630 --> 00:14:31,290 You may not like red team, you may not like Monero. 156 00:14:32,030 --> 00:14:39,850 You may like the biohacking village though and IOT is the best right so you like those two villages, and you'll be able to select them. 157 00:14:40,050 --> 00:14:43,650 I'm hoping this is working later in the evening. 158 00:14:43,730 --> 00:14:47,830 So, you, you can see this site. 159 00:14:47,830 --> 00:14:51,390 You can see, let me see if I point in the right direction. 160 00:14:51,550 --> 00:14:52,350 No. 161 00:14:52,650 --> 00:14:55,870 You can see. 162 00:14:55,870 --> 00:15:03,010 Right, so you can see this site right now if you go to that URL, it's live. 163 00:15:04,570 --> 00:15:14,270 But you will only be able to onboard your own device, as intended, a little bit later after we get it working. 164 00:15:16,290 --> 00:15:22,410 So I, I'm not going to demonstrate that until tomorrow until we get into the advanced things tomorrow. 165 00:15:22,410 --> 00:15:26,590 That's one of the content parts that I will need to postpone. 166 00:15:27,050 --> 00:15:43,050 But in any case, doesn't matter because if you read this, the part that we did get right so far is in green, you know green is kind of the getting started all okay color. 167 00:15:43,830 --> 00:15:48,810 And it basically says, you can read that can't you. 168 00:15:49,130 --> 00:16:02,610 It says that one of the best ways to get started to know that your badge is working to be able to use it in a productive manner is to use NFC tools. 169 00:16:02,710 --> 00:16:05,610 Right, so I'm not sure what happens if I push on that. 170 00:16:05,750 --> 00:16:08,290 Okay, so it goes to the developers website. 171 00:16:08,290 --> 00:16:11,610 This is wake dev or something like that. 172 00:16:12,070 --> 00:16:19,370 And this is just documentation, I believe it tells you how to install and where to find the applications. 173 00:16:19,710 --> 00:16:24,010 So you can see that one of the places the typical Google Store. 174 00:16:24,010 --> 00:16:28,350 I don't know about Amazon and these other things. 175 00:16:28,350 --> 00:16:35,070 It's also on the Apple iOS catalog, what is it called shop, store, whatever. 176 00:16:36,710 --> 00:16:40,830 And so that's how do I get back. 177 00:16:40,830 --> 00:16:44,470 Right, so that's NFC tools over there. 178 00:16:45,010 --> 00:16:50,110 NFC tools right so I have already installed that I'm just going to run that. 179 00:16:50,210 --> 00:16:52,370 I have the pro version. 180 00:16:52,370 --> 00:16:57,170 And it makes me feel, makes me feel like really pro. 181 00:16:57,830 --> 00:16:59,870 So that's why I got the pro version. 182 00:17:00,110 --> 00:17:02,970 And, but you can get the regular version. 183 00:17:03,550 --> 00:17:11,890 It was, to be honest, jokes aside, it was kind of an experiment, I thought, okay I'm using this thing all the time. 184 00:17:12,010 --> 00:17:17,670 And maybe there's some advanced methods and techniques in the pro version. 185 00:17:17,670 --> 00:17:25,550 And I really haven't found a big difference between the, the one that's not labeled as pro, and this one. 186 00:17:26,290 --> 00:17:28,030 Decide for yourself. 187 00:17:28,590 --> 00:17:31,610 So the quick test. 188 00:17:31,610 --> 00:17:33,110 I'm going to do that now. 189 00:17:33,310 --> 00:17:36,290 Do you see this screen that it's empty. 190 00:17:36,290 --> 00:17:39,170 Try to memorize what's on there it's almost empty. 191 00:17:39,170 --> 00:17:42,430 There's just two lines approach and NFC tag. 192 00:17:42,510 --> 00:17:45,270 Welcome to the you know you see what's on there. 193 00:17:45,270 --> 00:17:49,650 The trouble is that every time I show that the badge device. 194 00:17:49,990 --> 00:17:51,930 You can't see the front of the screen. 195 00:17:52,690 --> 00:17:54,930 So that's why this is going to be a bit difficult. 196 00:17:54,930 --> 00:17:57,330 Let me get something to drink here. 197 00:18:01,890 --> 00:18:12,090 Okay, so, um, so it's a bit challenging you can't see the front of the screen and the front of the badge at the same time because they must be. 198 00:18:12,170 --> 00:18:14,370 They must be back to back. 199 00:18:15,150 --> 00:18:19,670 That's why the back of the badge is protective leather. 200 00:18:19,950 --> 00:18:29,730 Okay, if this was metal like copper traces and jagged parts you put that on your lens, then the lens would get damaged. 201 00:18:29,730 --> 00:18:34,710 Instead, it's a nice synthetic leather finished back. 202 00:18:34,710 --> 00:18:36,590 It's called leatherette, I think. 203 00:18:36,750 --> 00:18:43,350 So, feel free to just slide that on there, it won't do any damage, I think. 204 00:18:44,090 --> 00:18:50,470 Unless you have a crystal diamond phone or something, but that's the purpose of the leather. 205 00:18:50,710 --> 00:18:55,330 So the back of the badge must be placed on the back of your phone. 206 00:18:56,730 --> 00:18:59,530 For any of this to work at all. 207 00:18:59,870 --> 00:19:11,130 You have to have There's probably all kinds of personal secret data coming on the phone, oh no. 208 00:19:11,130 --> 00:19:14,850 So anyway, you may see something there. 209 00:19:14,850 --> 00:19:21,870 You may see, for example, that there is a setting called NFC. 210 00:19:21,870 --> 00:19:24,570 Oh, let me do that again. 211 00:19:24,570 --> 00:19:26,430 There is a setting. 212 00:19:26,430 --> 00:19:29,070 And it's called NFC. 213 00:19:31,110 --> 00:19:33,610 Hello camera, please focus. 214 00:19:33,710 --> 00:19:34,530 There. 215 00:19:34,870 --> 00:19:38,030 It's not too well focused, but in any case, you get the point. 216 00:19:38,030 --> 00:19:44,830 You can see that Bluetooth is there, that NFC is there, that airplane mode. 217 00:19:44,830 --> 00:19:50,670 So the NFC, that symbol, that's very, very, very important. 218 00:19:50,670 --> 00:19:58,830 In some cases, I'm not going to go through all the screens, but in some cases you can turn on Android Beam and things like that. 219 00:19:58,830 --> 00:20:00,470 They're related to NFC. 220 00:20:00,470 --> 00:20:06,930 What you won't find on here is a word RFID, although these are RFID standards. 221 00:20:07,170 --> 00:20:10,310 Okay, so if you're curious about that. 222 00:20:10,690 --> 00:20:14,790 Let me just remove that while all the private information is scrolling. 223 00:20:15,670 --> 00:20:23,850 Okay, so this badge must be placed on the back of this after your NFC circuit is turned on, as I showed. 224 00:20:24,450 --> 00:20:30,830 A normal device, as soon as you do that, would activate the circuit, it would turn it on. 225 00:20:30,830 --> 00:20:34,230 Let me show you how that works with my 226 00:20:37,290 --> 00:20:41,570 with my fabrication laboratory key. 227 00:20:41,570 --> 00:20:47,090 Okay, this is my fabrication laboratory key and I'm just holding my thumb over the private data. 228 00:20:47,730 --> 00:20:52,310 And I will just put this on the back. 229 00:20:56,930 --> 00:20:57,790 See that? 230 00:20:57,790 --> 00:21:01,730 You maybe even heard that, because it does make a sound. 231 00:21:02,930 --> 00:21:08,810 So, that's what the data on my key is. 232 00:21:08,950 --> 00:21:11,230 Maybe you'd like to have that data. 233 00:21:13,990 --> 00:21:17,250 Doesn't help much because this is just one of the two factors. 234 00:21:18,070 --> 00:21:21,330 And it's kind of a low value identifier. 235 00:21:24,890 --> 00:21:32,990 So, that's what we get with a classic NFC data transmission. 236 00:21:36,690 --> 00:21:48,890 The non-classic one, like this badge, has a method of defending against opportunistic data theft. 237 00:21:48,890 --> 00:21:50,590 So, what does that mean? 238 00:21:50,990 --> 00:21:55,210 So, if I don't have my things here. 239 00:21:55,470 --> 00:22:02,310 If I put this If I put this card on a table, which I do not control. 240 00:22:02,310 --> 00:22:06,810 It's not me that bought, owned, created, built the table. 241 00:22:06,810 --> 00:22:09,690 Then it can be that somebody else manipulated the table. 242 00:22:09,690 --> 00:22:27,150 Any table in the world, you can attach a transmitter and receiver to it, or transceiver, and it can be used to harvest data in a in a very bad manner. 243 00:22:27,150 --> 00:22:42,590 So, so what we're going to do is protect the data on here by simply requiring requiring that a human pushes on one of the three buttons before there is any possibility of data exchange. 244 00:22:43,340 --> 00:23:02,350 This isn't a perfect security feature because because, well, because nothing's perfect and simply because what's happening is that unless you push on one of these three buttons, the antenna, which maybe I can show. 245 00:23:04,250 --> 00:23:17,330 Here it is, the antenna on the back is not connected to the EEPROM data storage on the front. 246 00:23:17,330 --> 00:23:18,950 Okay, do you kind of understand that? 247 00:23:18,950 --> 00:23:38,610 That without pushing on this button, if you hear that click, without pushing on this button, if I release and do not push, then this antenna is not connected to any of the data storage ICs. 248 00:23:38,610 --> 00:23:57,490 And in this moment, the storage ICs, although they do have transceivers with absolutely no 13 megahertz antenna connected to them, it's not impossible, but it's likely close to impossible to easily harvest data off of there. 249 00:23:57,490 --> 00:24:04,150 Okay, so that's what I call defense of opportunistic data theft. 250 00:24:04,150 --> 00:24:15,810 You put this badge on most tables in the world in which there is an embedded attack surface and they're somewhat protected against them. 251 00:24:16,310 --> 00:24:24,310 Okay, it still doesn't mean you want to put your birth certificate and images and what are all of these very valuable private data on there. 252 00:24:24,310 --> 00:24:25,810 I do not recommend that. 253 00:24:25,810 --> 00:24:32,010 In some cases, these badges can replace or substitute for paper wallets. 254 00:24:32,010 --> 00:24:39,670 So if you're ever walking around with a paper wallet, you know very well, any camera in the room can gather, can harvest your secret key. 255 00:24:39,670 --> 00:24:47,430 Consider almost everything in the world that doesn't have a secure element to be less than perfect security. 256 00:24:47,430 --> 00:24:52,530 All right, so we got a bit off topic there. 257 00:24:52,630 --> 00:24:57,510 What I was trying to do is push on this and connect it to the phone. 258 00:24:57,510 --> 00:24:59,070 That's what I'm going to do right now. 259 00:24:59,070 --> 00:25:01,490 We saw an example with a plastic card. 260 00:25:02,370 --> 00:25:04,330 And now I will do it with a badge. 261 00:25:04,330 --> 00:25:06,750 So I'm going to push right now. 262 00:25:08,250 --> 00:25:11,670 All right, so we got some data off of the badge. 263 00:25:11,730 --> 00:25:13,010 This data belongs to me. 264 00:25:13,010 --> 00:25:15,710 So this does not qualify as theft. 265 00:25:16,430 --> 00:25:18,330 So what do we see here? 266 00:25:18,390 --> 00:25:20,010 There's just quite a lot of stuff. 267 00:25:20,010 --> 00:25:22,910 In fact, sometimes you can scroll. 268 00:25:23,430 --> 00:25:26,870 The first thing that you see, I pushed the star. 269 00:25:27,110 --> 00:25:27,850 That's what I did. 270 00:25:27,850 --> 00:25:29,130 I pushed this one. 271 00:25:30,850 --> 00:25:36,970 And the star is connected to an EEPROM, which is an ISO 15693 standard. 272 00:25:36,970 --> 00:25:43,130 This is an RFID that provides an NDEF, or what does NDEF stand for? 273 00:25:43,130 --> 00:25:46,930 It's an NFC data format. 274 00:25:48,250 --> 00:25:55,670 The manufacturer of the EEPROMs, you can see because it's very clearly ST Microelectronics in France. 275 00:25:56,130 --> 00:25:58,130 And then we have technologies available. 276 00:25:58,130 --> 00:25:59,510 One of them is NDEF. 277 00:25:59,510 --> 00:26:00,790 We have a serial number. 278 00:26:00,790 --> 00:26:10,630 Each of the EEPROMs, each of these EEPROMs on each individual badge, so we have very, very many of them, has an individual serial number. 279 00:26:10,630 --> 00:26:13,410 This is not something we decide. 280 00:26:13,410 --> 00:26:24,410 You can't buy a telephone or a computer or a badge or any electronic device where there are no serial numbers inside. 281 00:26:24,410 --> 00:26:41,630 It's simply a very common practice in industry that all of these, all of the devices expensive enough, the parts like integrated circuits to, or with a need to be unique, like memory EEPROMs and things, they have serial numbers. 282 00:26:41,630 --> 00:26:42,250 Okay. 283 00:26:42,710 --> 00:26:44,590 This can be useful as well. 284 00:26:44,590 --> 00:26:49,250 You can use this as a unique identifier, if you like. 285 00:26:49,250 --> 00:26:55,550 Alright, so some of the things here, we can use to understand like this size. 286 00:26:55,610 --> 00:26:58,350 That's how much data you can store on there. 287 00:26:58,350 --> 00:26:59,650 It's a very small one. 288 00:26:59,650 --> 00:27:03,290 There's just 50 bytes for this star. 289 00:27:03,470 --> 00:27:04,930 Just 50 bytes. 290 00:27:04,930 --> 00:27:07,550 This one is 50 bytes as well. 291 00:27:08,210 --> 00:27:13,030 And they're both ISO 15693. 292 00:27:13,030 --> 00:27:14,850 The last one, the sun. 293 00:27:14,850 --> 00:27:17,550 This is a different IC. 294 00:27:17,610 --> 00:27:22,190 So why don't we, why don't we try the sun now, instead of me telling you about it. 295 00:27:23,010 --> 00:27:26,030 Let's put practice into... 296 00:27:26,030 --> 00:27:26,770 Wait a minute. 297 00:27:26,770 --> 00:27:29,570 Okay, so now I'm going to push on the sun. 298 00:27:29,570 --> 00:27:30,730 Ready for this? 299 00:27:32,970 --> 00:27:36,270 I have to line it up on the antenna. 300 00:27:40,880 --> 00:27:42,300 That is not working. 301 00:27:44,740 --> 00:27:45,860 There it is. 302 00:27:46,620 --> 00:27:54,960 So, now it's no longer showing an ISO 15693 standard, it's showing an ISO 14443. 303 00:27:54,960 --> 00:28:07,480 Okay, so it's not telling us what other manufacturers and service providers call their products. 304 00:28:07,480 --> 00:28:10,040 But if we go back now. 305 00:28:10,040 --> 00:28:16,260 Another thing to notice, please take a look here the size is much larger it's eight kilobytes now. 306 00:28:16,260 --> 00:28:17,840 So that's a really big one. 307 00:28:17,840 --> 00:28:19,400 Okay, that's really big. 308 00:28:19,400 --> 00:28:22,080 I think that's the largest size I know of. 309 00:28:22,200 --> 00:28:29,980 If we go back here to this, to this fabrication laboratory key. 310 00:28:29,980 --> 00:28:36,340 Let's take a look at it and see if it's this is a 144443 as well. 311 00:28:36,760 --> 00:28:46,320 Okay, and here they even labeled it MyFair, which some of you may have heard of it's a technology brand style word. 312 00:28:46,880 --> 00:28:52,920 Like I think the clam cards which are used on the London Metro subway. 313 00:28:52,920 --> 00:28:56,320 I mean they all have their names clam card and so on. 314 00:28:56,400 --> 00:29:01,220 I'm not sure if MyFair is always 14443. 315 00:29:01,460 --> 00:29:07,900 In any case, what this is really just delivering is the serial number. 316 00:29:08,680 --> 00:29:12,260 And this is what I use to operate the laser cutter. 317 00:29:12,260 --> 00:29:20,300 Okay, so if you were to, I mean, I'll tell you the truth, you can clone this serial number onto your own card. 318 00:29:20,300 --> 00:29:30,480 And then travel all the way to wherever this machine is that has this reader, whether it's Japan, Greenland, Brazil, or wherever they decide to ship this device. 319 00:29:30,480 --> 00:29:34,980 And then you will be able to use this device and impersonate me if you're willing to break the law. 320 00:29:34,980 --> 00:29:36,780 Okay, so don't do that. 321 00:29:37,020 --> 00:29:42,540 This is my card, but I'm not so worried because it's very low value identifier. 322 00:29:43,240 --> 00:29:47,760 Alright, so what have we learned so far. 323 00:29:47,940 --> 00:29:49,200 These devices. 324 00:29:50,060 --> 00:29:57,340 These badges work very well with, everybody say it at once, NFC tools. 325 00:29:57,340 --> 00:29:59,440 You can't see it because it's not focused. 326 00:29:59,740 --> 00:30:04,980 So once you start NFC tools you can start using your badge, that's kind of what we're trying to get at. 327 00:30:05,600 --> 00:30:08,740 Flip the phone over, put the badge on top. 328 00:30:09,580 --> 00:30:14,280 The first two buttons are much easier to get a read on. 329 00:30:14,400 --> 00:30:17,220 So I'm going to do it this way now and try to listen. 330 00:30:22,690 --> 00:30:23,830 Did you hear that? 331 00:30:23,830 --> 00:30:27,530 And then I turn the phone over to show you, and it's got the data on there. 332 00:30:28,250 --> 00:30:30,370 All right, let me do it again with the middle one. 333 00:30:34,010 --> 00:30:37,450 So you probably heard that, and then we have a different standard. 334 00:30:37,490 --> 00:30:39,970 I'm sorry, no, it's still the 15693. 335 00:30:40,990 --> 00:30:44,030 Turn it over again for the sun. 336 00:30:44,150 --> 00:30:49,170 This one I recommend that you twist it around, it's much more difficult. 337 00:30:49,170 --> 00:30:50,690 This is a short range tag. 338 00:30:50,690 --> 00:30:52,350 These are both long range. 339 00:30:52,470 --> 00:30:53,430 This one's short range. 340 00:30:53,430 --> 00:30:54,330 So let's see. 341 00:30:58,820 --> 00:31:01,980 Okay, I got it just simply because I'm doing this all the time. 342 00:31:03,560 --> 00:31:05,300 But it's going to be really difficult. 343 00:31:05,300 --> 00:31:16,760 And if your antenna, if the antenna in the phone, in your phone, is not very high up here, but it's lower down there, then you're going to need to put the badge in a different part of the phone. 344 00:31:16,760 --> 00:31:18,100 You understand that? 345 00:31:18,100 --> 00:31:23,520 I mean, there is tablets, there are different devices that have NFC inside. 346 00:31:23,520 --> 00:31:31,700 So getting started with any of these computing devices, I've even seen laptops with NFC circuits and antennas. 347 00:31:31,700 --> 00:31:35,180 You can try them, it's kind of more common to use a phone. 348 00:31:35,180 --> 00:31:41,120 Almost every phone that's been manufactured in the last two or three years has an NFC circuit inside. 349 00:31:41,300 --> 00:31:49,800 I can kind of imagine that there's phones that are made for children or something, or the absolute cheapest ones that don't have them. 350 00:31:50,900 --> 00:31:55,680 But you're going to, you're going to have a phone probably that has NFC on there. 351 00:31:56,180 --> 00:32:04,720 All right, so let's, let's think about what to do next. 352 00:32:04,720 --> 00:32:09,660 We haven't talked about the technology, but it's not, we need a microscope for that. 353 00:32:09,960 --> 00:32:12,100 So it's not going to be possible. 354 00:32:14,140 --> 00:32:18,800 One of the things we could talk about. 355 00:32:21,810 --> 00:32:22,550 Yeah. 356 00:32:24,150 --> 00:32:26,610 I have a couple. 357 00:32:27,510 --> 00:32:30,010 Okay, that could be a question now. 358 00:32:30,450 --> 00:32:33,110 The stream is very choppy I hear. 359 00:32:34,070 --> 00:32:36,670 Why is it choppy we were? 360 00:32:38,270 --> 00:32:39,550 Strange. 361 00:32:39,550 --> 00:32:40,650 Okay. 362 00:32:41,530 --> 00:32:43,470 Thanks for telling me. 363 00:32:47,560 --> 00:32:52,840 So, okay, so let's go back to the website. 364 00:32:52,840 --> 00:32:57,820 All right, let's, let's figure out what we have covered here. 365 00:32:59,830 --> 00:33:03,650 So we got started on the... 366 00:33:03,650 --> 00:33:05,390 There you can read that better. 367 00:33:05,390 --> 00:33:12,150 We got started on the website, which is what is easy to find. 368 00:33:12,150 --> 00:33:16,170 It's on all of the packaging, it's the QR codes. 369 00:33:16,470 --> 00:33:19,250 It's hopefully the go to place. 370 00:33:19,710 --> 00:33:20,630 Right. 371 00:33:21,750 --> 00:33:26,210 You find that you have some short information. 372 00:33:27,290 --> 00:33:30,510 The green tells you how to get to NFC tools. 373 00:33:30,510 --> 00:33:33,250 You need to install that it's an application. 374 00:33:34,050 --> 00:33:50,090 And eventually we will have things here, guiding you to adjust your phone's browser in order to make it capable and compatible with the badge using NFC. 375 00:33:50,090 --> 00:33:54,450 You can kind of read the text is finished, so it's clear enough. 376 00:33:54,450 --> 00:34:02,690 It says there, platform features, you need to enable the NFC platform features. 377 00:34:02,690 --> 00:34:07,210 I'll actually do that now, because it may not be so clear. 378 00:34:07,270 --> 00:34:18,650 But in order to use a web browser like this one, when we're going to type URLs in here and try to interact with one of these badges from a web browser. 379 00:34:19,010 --> 00:34:23,150 That's what we're going to need to do this thing in the blue. 380 00:34:23,150 --> 00:34:29,110 All right, we're going to need to copy this text. 381 00:34:32,270 --> 00:34:35,390 Then we're going to put that up here. 382 00:34:35,970 --> 00:34:37,050 All right. 383 00:34:41,260 --> 00:34:43,280 Let's paste that, shall we. 384 00:34:43,540 --> 00:34:47,640 I'm doing this slowly because Reware said everything's choppy here. 385 00:34:47,980 --> 00:34:49,420 So I'm going to paste. 386 00:34:50,440 --> 00:34:52,140 That didn't work. 387 00:34:54,460 --> 00:34:56,980 So, that worked this time. 388 00:35:01,770 --> 00:35:03,610 All right, so what do we see here. 389 00:35:03,610 --> 00:35:06,750 This is where everything turns red, you get warnings. 390 00:35:08,090 --> 00:35:11,150 Experimental web features is what I have enabled there. 391 00:35:11,150 --> 00:35:14,090 That's why it's the very first one, it's at the top. 392 00:35:14,090 --> 00:35:16,770 You will probably have to scroll down. 393 00:35:16,770 --> 00:35:24,810 Okay, there's all kinds of things here, you can enable, disable, there's web RTC multichannel, you get the idea. 394 00:35:24,810 --> 00:35:31,110 But if you do not have this experimental web platform features enabled. 395 00:35:31,510 --> 00:35:40,670 That just means that you will be limited to using an application like NFC tools. 396 00:35:40,690 --> 00:35:49,310 You can use NFC tools, whenever whenever your NFC circuit is turned on. 397 00:35:49,350 --> 00:35:53,230 That's when you can use NFC tools. 398 00:35:54,310 --> 00:36:01,210 All right, but if you want to use a web browser to access your badge. 399 00:36:01,210 --> 00:36:07,090 That's when you need to go to the Chrome double colon flags. 400 00:36:07,090 --> 00:36:17,530 And that's when you need I apologize for this actually it's very uncomfortable, right, this is what most people don't like to do is adjust and configure their phones. 401 00:36:18,090 --> 00:36:22,130 There is a long story to this, I will tell you the short version. 402 00:36:23,510 --> 00:36:30,850 Some manufacturers like Google lock down certain features, they force you to enable them. 403 00:36:30,850 --> 00:36:47,450 We were able to until the 29th of July, we had a special key from the, what was it the Google Chrome department that issued us a key as developers. 404 00:36:48,350 --> 00:36:51,310 And on the 29th that key expired. 405 00:36:51,310 --> 00:36:55,350 So this is what we have to do since the 29th. 406 00:36:55,730 --> 00:37:01,410 Is this still very choppy RERAR, you want to tell me if it's improved or not. 407 00:37:03,850 --> 00:37:07,970 In any case, this is documented in many places. 408 00:37:08,530 --> 00:37:12,770 Like we saw before, documented here. 409 00:37:13,410 --> 00:37:26,670 And we even put a URL here I believe if you click on that, that it goes to a kind of a explanation about what this is all about experimental API's if you want to read this. 410 00:37:26,670 --> 00:37:28,230 This is kind of for hackers. 411 00:37:28,230 --> 00:37:45,990 So if you're not comfortable adjusting and configuring your phone, then you can still use your badge by either waiting for the Chrome origin program for developers to kick in again, because I assume after the 29th it finished then we will get another key someday. 412 00:37:46,790 --> 00:37:53,970 You can either wait for that or you can use NFC tools, which works out of the box, immediately. 413 00:37:53,970 --> 00:37:56,130 Right. 414 00:37:56,510 --> 00:38:00,970 So, those are the options. 415 00:38:00,970 --> 00:38:08,110 And I'll just emphasize once again that our website up here. 416 00:38:08,110 --> 00:38:10,130 The Bob website. 417 00:38:10,130 --> 00:38:14,110 This will be a method for you to onboard your device. 418 00:38:14,960 --> 00:38:32,910 According to your personal preferences, whether you like the biohacking village more than the red team or the red team more than Monero or maybe you want a combination, which will be possible as well to combine the different village profiles. 419 00:38:33,710 --> 00:38:35,650 All right, so... 420 00:38:36,570 --> 00:38:38,530 See what Rewire says. 421 00:38:38,530 --> 00:38:41,990 It will be choppy unless you turn down the quality. 422 00:38:41,990 --> 00:38:42,950 All right. 423 00:38:44,190 --> 00:38:46,650 Do I really want to do that? 424 00:38:46,650 --> 00:38:51,850 Re-adjust and configure OBS mid-speech? 425 00:38:52,410 --> 00:38:54,330 Oh, God. 426 00:38:55,330 --> 00:38:57,690 I don't think so. 427 00:38:59,970 --> 00:39:02,790 But we've got 10 more minutes. 428 00:39:05,380 --> 00:39:06,520 Okay. 429 00:39:06,520 --> 00:39:07,120 Okay. 430 00:39:07,120 --> 00:39:13,020 Okay, Justin, I'm going to try this, but I will definitely blame you if this goes badly. 431 00:39:14,740 --> 00:39:18,120 Okay, so let me see if I can do this quickly. 432 00:39:18,120 --> 00:39:20,240 There's I've got the video already there. 433 00:39:20,440 --> 00:39:22,920 Okay, Justin, new problem. 434 00:39:22,920 --> 00:39:26,600 I mean, I can't adjust anything while I'm streaming. 435 00:39:26,600 --> 00:39:34,480 Right, so I'm not going to do it because turning streaming off and then to get it back on again is going to be three minutes of dead air. 436 00:39:34,720 --> 00:39:36,840 I think you agree that would be a bad idea. 437 00:39:36,840 --> 00:39:40,780 So, can't change any settings on OBS while you're streaming. 438 00:39:41,760 --> 00:39:43,700 I will have to change it for tomorrow. 439 00:39:43,700 --> 00:39:46,400 Hopefully tomorrow will be less choppy. 440 00:39:46,720 --> 00:39:47,540 All right. 441 00:39:48,940 --> 00:39:56,840 So in, in sense, in a sense, that was the getting started speech. 442 00:39:57,520 --> 00:40:00,620 We covered the first of the two URLs. 443 00:40:00,860 --> 00:40:07,680 And the second, you can hear just read that I mean you can you can go to the second on your own. 444 00:40:08,140 --> 00:40:11,920 It would make no sense to try that now because I'm not an expert. 445 00:40:13,380 --> 00:40:15,740 It's actually kind of hard to read. 446 00:40:16,260 --> 00:40:17,520 Foursuit's game. 447 00:40:18,380 --> 00:40:35,040 So, yeah, if you're feeling creative and you're interested in, in knowing what else the batch can do and how the rogues village is using it, then either wait until Sunday when they explain it in a presentation, or just go to the URL right now download the manual, 448 00:40:35,040 --> 00:40:40,020 free of charge, go to the go there, you know, pretend like you have a badge in your hand if you don't have one. 449 00:40:40,600 --> 00:40:46,540 And that's how you can research and hack a hack around a bit, because after all this is DEF CON. 450 00:40:47,220 --> 00:40:52,480 Isn't that a nice manual, one of the best illustrators and graphic artists in the world made that for us. 451 00:40:52,880 --> 00:40:56,020 And he even she or he even wrote. 452 00:40:56,160 --> 00:40:57,260 Thanks for hacking. 453 00:41:00,530 --> 00:41:01,090 Right. 454 00:41:01,090 --> 00:41:05,890 Okay, so this was meant to be a very slow and gentle introduction. 455 00:41:05,890 --> 00:41:10,250 And it was the getting started with the village badge. 456 00:41:11,450 --> 00:41:23,650 Tomorrow we will do some impersonation some attacks on our own devices, things like identity cards and two factor authentication devices. 457 00:41:23,790 --> 00:41:26,830 Yeah, there is 10 more minutes. 458 00:41:26,830 --> 00:41:32,690 So, if the, if the video was not too choppy. 459 00:41:32,690 --> 00:41:35,590 That you couldn't understand anything. 460 00:41:36,330 --> 00:41:40,770 Then it's now time to ask your question. 461 00:41:40,770 --> 00:41:48,370 You can ask questions on the traditional the official DEF CON channels. 462 00:41:48,370 --> 00:41:50,810 Those are all on discord. 463 00:41:50,870 --> 00:42:01,010 Just like you cannot participate in a normal DEF CON year by going to Canada. 464 00:42:01,010 --> 00:42:08,590 You also can't fully participate on a virtual DEF CON year without going to discord. 465 00:42:08,590 --> 00:42:09,350 All right. 466 00:42:09,610 --> 00:42:17,170 You can kind of watch these videos on Twitch and YouTube, but really participating, you want to check out those channels on discord. 467 00:42:17,170 --> 00:42:19,750 Okay, so maybe there's questions there now. 468 00:42:19,750 --> 00:42:21,610 Let me just take a look. 469 00:42:23,470 --> 00:42:26,970 I don't see any. 470 00:42:27,490 --> 00:42:30,030 On the right channel. 471 00:42:32,770 --> 00:42:35,970 Don't see any questions. 472 00:42:36,590 --> 00:42:43,810 So, I'm going to assume that that we are done. 473 00:42:43,810 --> 00:42:48,330 But before I check out for the day. 474 00:42:48,330 --> 00:42:52,850 Going to explain something in case you do have questions later. 475 00:42:54,210 --> 00:42:56,890 So if you have questions later. 476 00:42:57,430 --> 00:42:59,770 About these nifty devices. 477 00:43:00,390 --> 00:43:02,930 Then we have a help desk. 478 00:43:02,970 --> 00:43:05,250 Has nothing to do with DEF CON. 479 00:43:08,180 --> 00:43:09,920 We have a help desk. 480 00:43:09,920 --> 00:43:26,240 It's a Monero devices help desk, so it's not manned by staffed employees, right, we're all just volunteers, and it's kind of a community, anyone can join, and everyone is encouraged to provide as many questions with many answers as questions. 481 00:43:26,240 --> 00:43:26,800 Right . 482 00:43:26,800 --> 00:43:29,300 Here's a help desk location. 483 00:43:29,880 --> 00:43:32,260 I'm not even going to write the HTTP. 484 00:43:43,870 --> 00:43:45,530 It's calm, it's not org. 485 00:43:45,530 --> 00:43:47,730 Okay, just try to remember that. 486 00:43:47,850 --> 00:43:51,690 So you can get it, you can launch questions there. 487 00:43:56,210 --> 00:43:57,770 What else do we have. 488 00:43:57,770 --> 00:43:58,750 There's another. 489 00:43:59,910 --> 00:44:01,510 There's this as well. 490 00:44:01,510 --> 00:44:08,570 Since we finished early I'll just run through a few reused slides. 491 00:44:08,570 --> 00:44:11,650 All right, so you want to get a badge, you can find them. 492 00:44:11,650 --> 00:44:13,630 There's three places in fact. 493 00:44:13,830 --> 00:44:15,290 There's three places. 494 00:44:15,570 --> 00:44:19,910 So maybe with all the extra time we have. 495 00:44:20,230 --> 00:44:23,990 I maybe failed to mention that if you look there. 496 00:44:25,490 --> 00:44:27,910 You go to the menu see how that works. 497 00:44:29,190 --> 00:44:33,210 On the, on the badge on the, on the Bob site. 498 00:44:34,530 --> 00:44:36,330 So go to the menu. 499 00:44:36,590 --> 00:44:38,310 You've got your shops there. 500 00:44:38,310 --> 00:44:40,530 Most of this is working properly. 501 00:44:40,870 --> 00:44:44,050 So let's imagine you'd really like to have have one of these badges you want. 502 00:44:44,050 --> 00:44:45,970 You want a full featured. 503 00:44:46,630 --> 00:44:48,650 You want a full featured. 504 00:44:48,770 --> 00:44:55,330 One of the best of the best badges, you go to Cypher Market or Hack 5. 505 00:44:56,210 --> 00:44:58,490 Let's see which one should I choose. 506 00:44:58,490 --> 00:45:00,490 I'm sorry Hack 5 I haven't even. 507 00:45:01,810 --> 00:45:03,310 See if that works. 508 00:45:03,310 --> 00:45:03,830 Yeah. 509 00:45:03,830 --> 00:45:06,270 Okay, so that's, that's how that works. 510 00:45:06,350 --> 00:45:10,630 Here is Cypher Market. 511 00:45:14,550 --> 00:45:15,590 Hello. 512 00:45:15,590 --> 00:45:16,430 Okay. 513 00:45:16,670 --> 00:45:17,630 See how that works. 514 00:45:17,630 --> 00:45:19,430 So Cypher Market has more colors. 515 00:45:19,470 --> 00:45:25,950 And if you prefer a, if you prefer a do it yourself model. 516 00:45:25,950 --> 00:45:32,710 Then unfortunately, I couldn't convince the others to list all these different models. 517 00:45:32,850 --> 00:45:34,930 So, couldn't get that done. 518 00:45:34,930 --> 00:45:42,590 So the only place where you can get a do it yourself model, that's going to be here on the factory shop. 519 00:45:42,950 --> 00:45:47,150 All right, so those are kind of your rundown of your choices. 520 00:45:47,630 --> 00:45:51,030 The other thing is that this thing here. 521 00:45:51,030 --> 00:45:54,230 This stands for source code management. 522 00:45:54,230 --> 00:45:59,150 So this is where all of our open source archives repositories are. 523 00:45:59,750 --> 00:46:01,730 That's very useful as well. 524 00:46:01,930 --> 00:46:07,270 All right, so we're finishing five minutes early which is refreshing. 525 00:46:07,270 --> 00:46:09,150 We usually go over time. 526 00:46:09,150 --> 00:46:17,150 This drives AJ and SGP and all of the administrators, drives them crazy. 527 00:46:17,150 --> 00:46:19,270 This time we're finishing early. 528 00:46:19,710 --> 00:46:20,990 One more. 529 00:46:22,230 --> 00:46:30,670 One more look at the discord channel, and there's nothing there, which means that we just finished 530 00:46:33,830 --> 00:46:41,830 the getting started with this year's village badge, intervillage badge. 531 00:46:41,830 --> 00:47:01,830 Okay, don't forget that if you're interested, and you have time tomorrow, Saturday, that we have what, not two but only one badge clinic, during which we can talk about some more advanced things like impersonation, things like that, backing up your data. 532 00:47:02,750 --> 00:47:05,130 And then Sunday we have the same thing. 533 00:47:05,130 --> 00:47:11,430 Sunday we'll talk about the game, the rogues village game as well, but that's not on the Monero village. 534 00:47:11,430 --> 00:47:15,730 That presentation is happening on the rogues village. 535 00:47:15,890 --> 00:47:17,310 Big surprise. 536 00:47:18,230 --> 00:47:39,510 All right, that's all for today folks and I think we're, you're in luck if you're still watching because if you're not bored to death, because there is still a very important very intriguing speech coming up I'm sure the moderator will tell you but I think Rerar in fact the famous Rerar is going to give a speech now is that right, 537 00:47:39,510 --> 00:47:41,210 or did I get that wrong. 538 00:47:41,850 --> 00:47:44,170 Let me just check quickly. 539 00:47:52,670 --> 00:47:56,790 I know that he's closing the village on Sunday. 540 00:48:01,190 --> 00:48:03,270 And for today. 541 00:48:04,270 --> 00:48:09,050 In fact, Rerar is speaking next, and it should be a good one.
