1 00:00:00,000 --> 00:00:18,580 [Intro Music] 2 00:00:18,580 --> 00:00:21,690 Engel: Good morning, Linus! Linus: Good morning, Sebastian! 3 00:00:21,690 --> 00:00:28,260 [Applause] 4 00:00:28,260 --> 00:00:32,510 I'm glad, you showed up so numerous and fell 5 00:00:32,510 --> 00:00:36,390 for this baiting title! I want to talk about human 6 00:00:36,390 --> 00:00:40,210 factors in IT security and chose "hacking brains" for the title. 7 00:00:40,210 --> 00:00:45,980 Background to this is the fact, that when you talk about "hackers" 8 00:00:45,980 --> 00:00:49,080 most people think of halfgods in black. 9 00:00:49,080 --> 00:00:52,399 Nobody really knows what they are doing, but those hackers 10 00:00:52,399 --> 00:00:56,690 get into my device somehow and i don't know what they want from me 11 00:00:56,690 --> 00:01:01,180 or how they did it. And the reality out there is 12 00:01:01,180 --> 00:01:06,229 typically pretty different than most people imagine it. I stand firm 13 00:01:06,229 --> 00:01:12,969 in the believe that basically all relevant problems in IT security 14 00:01:12,969 --> 00:01:18,479 have been solved in theory. So we don't have like... we don't miss the knowledge 15 00:01:18,479 --> 00:01:23,119 on solutions for particular problems, but we still can't make it work. 16 00:01:23,119 --> 00:01:26,419 Even though we've solved everything theoretically, 17 00:01:26,419 --> 00:01:31,780 the actual IT security is a desaster. 18 00:01:31,780 --> 00:01:36,650 And that's most likely, because we build some fascinating IT-mechanisms and 19 00:01:36,650 --> 00:01:40,901 we test them. As we can see this pole and it encloses some animal now, but 20 00:01:40,901 --> 00:01:44,011 if we observe it in reality, it looks more like that... 21 00:01:44,011 --> 00:01:51,221 [audience laughing] [someone singing to "Einzug der Gladiatoren"] 22 00:01:51,221 --> 00:01:55,309 23 00:01:55,309 --> 00:01:59,659 That's only a small threat and somehow 24 00:01:59,659 --> 00:02:04,219 we imagine, that it will be different with bigger threats. 25 00:02:04,219 --> 00:02:10,560 Let's have a look: We read about Emotet everywhere. 26 00:02:10,560 --> 00:02:15,160 Hackers compromise PCs, encrypt all the data, demand a lot of ransom, 27 00:02:15,160 --> 00:02:19,840 and Heise covered it a lot, until they got hit by it themselves. 28 00:02:19,840 --> 00:02:25,000 [laughter] That means, even those who really should have known better 29 00:02:25,000 --> 00:02:28,350 are still effected by it and i think that's 30 00:02:28,350 --> 00:02:31,340 pretty interresting. And if we have a look at what happens in the 31 00:02:31,340 --> 00:02:35,530 IT security research, even here on this congress, which is why i handed in this 32 00:02:35,530 --> 00:02:39,370 talk, so the research has to be avant garde. 33 00:02:39,370 --> 00:02:43,280 It's like big applause and Voodoo, and another exploit there and 34 00:02:43,280 --> 00:02:48,070 whatever, and remote code execution, while the reality on the other hand 35 00:02:48,070 --> 00:02:52,600 what actually happens out there, is actually more like this. 36 00:02:52,600 --> 00:02:58,341 Am I in already? This means, we basically live, 37 00:02:58,341 --> 00:03:02,000 because we as hackers and nerds find it interessting, we live like in 38 00:03:02,000 --> 00:03:07,780 this world, while the real crime that happens outside looks more like this! 39 00:03:07,780 --> 00:03:15,160 sleight of hands. and theses sleight of hands are not addressed or solved! 40 00:03:15,160 --> 00:03:18,730 And i think that's kinda counterproductive or bad, that we don't care about 41 00:03:18,730 --> 00:03:22,370 those problemfields, which prevail and are seen everywhere 42 00:03:22,370 --> 00:03:26,870 even in the "Heise" publishing company, that we don't address them. 43 00:03:26,870 --> 00:03:31,230 And we haven't made any progress on that front for years. 44 00:03:31,230 --> 00:03:34,410 I want to talk a bit about easy Scams, a bit about password issues, a little 45 00:03:34,410 --> 00:03:40,970 about malware. A scam that amused even us in the CCC, is the scam 46 00:03:40,970 --> 00:03:45,820 by the Chaos-Hacking-Group. They sent E-Mails that said: 47 00:03:45,820 --> 00:03:49,700 "Yeah i have compromised your system with a trojan and 48 00:03:49,700 --> 00:03:56,140 we are aware about your adventures on the internet. We know, that you love 49 00:03:56,140 --> 00:04:00,750 adult sites and know about your sex addiction." 50 00:04:00,750 --> 00:04:04,710 And try to blackmail those people. Provide a Bitcoin Wallet 51 00:04:04,710 --> 00:04:09,340 and, yeah, try to blackmail people. Intresstingly 52 00:04:09,340 --> 00:04:13,360 there are people, that are really concerned. They deny everything! 53 00:04:13,360 --> 00:04:18,500 Obviously this isn't true at all and there's just no truth to any of it. 54 00:04:18,500 --> 00:04:22,100 When you're practiced in blackmailing, you know: Don't pay anything until 55 00:04:22,100 --> 00:04:27,930 proof is provided. When people then try to inform themselfs and 56 00:04:27,930 --> 00:04:33,330 goolge it, they land here immediatly. 57 00:04:33,330 --> 00:04:36,830 When you google "Chaos-CC group", then some random websites explain 58 00:04:36,830 --> 00:04:40,410 that it's a trojan and you should 59 00:04:40,410 --> 00:04:47,180 download the next malware. 60 00:04:47,180 --> 00:04:52,470 Basically how to remove this damage. That means people are getting out of the 61 00:04:52,470 --> 00:04:57,120 frying pan into the fire. "Haha you want to get fooled! There i got another 62 00:04:57,120 --> 00:05:03,540 one for you. That means the world outside is relativly dangerous 63 00:05:03,540 --> 00:05:07,220 for our unknowing users. Let's have a look 64 00:05:07,220 --> 00:05:11,900 how this looks like when done by expierienced folks. The Linux 65 00:05:11,900 --> 00:05:16,950 Kernelmailinglist is known by a bunch of you. There recently was an E-Mail 66 00:05:16,950 --> 00:05:22,570 on the 31st of October, so a while ago. They even provided the password, yeah 67 00:05:22,570 --> 00:05:25,090 that's the next Level Scam: You just write some password leak 68 00:05:25,090 --> 00:05:28,400 with it and folks will get their pumps racing, because their password 69 00:05:28,400 --> 00:05:35,350 is written in the Mail and as before they wanted Bitcoins, amongst 70 00:05:35,350 --> 00:05:38,810 other things, from the Kernel-Devs themselfs. Bitcoin is pretty nice, 71 00:05:38,810 --> 00:05:42,180 You can have a look in the Blockchain and see how many the devs paid. 72 00:05:42,180 --> 00:05:47,970 In this wallet are 2.98 Bitcoin which has been about 19000€ 73 00:05:47,970 --> 00:05:51,410 some days ago. There are still people out there claiming 74 00:05:51,410 --> 00:05:54,480 you can't make a profit on linux. [laughter] 75 00:05:54,480 --> 00:06:01,401 [applause] This E-Mail 76 00:06:01,401 --> 00:06:05,520 was sent to many many more people outside the Kernellist, but i think, you get my 77 00:06:05,520 --> 00:06:08,500 point, and ask yourself: Why do we even do all that stuff we do 78 00:06:08,500 --> 00:06:11,120 ,when we could easily get people to send us their money 79 00:06:11,120 --> 00:06:17,140 with some spam mails. But there's more: transfer money, the classic! The CEO fraud 80 00:06:17,140 --> 00:06:22,310 Big topic. This is one of the big scenarios, that middle size and big 81 00:06:22,310 --> 00:06:26,240 size companys are exposed to. You get a mail, where it states 82 00:06:26,240 --> 00:06:30,340 "Ey, we need to pay those bills! It hast to happen TODAY" 83 00:06:30,340 --> 00:06:33,940 most of the time it's 84 00:06:33,940 --> 00:06:37,020 small amounts, that get overlooked. 85 00:06:37,020 --> 00:06:42,889 but can also be a lot worse. Acutally 86 00:06:42,889 --> 00:06:49,050 happend pretty often already, with a story like: "Yeah the big deal with the chinease 87 00:06:49,050 --> 00:06:53,040 is almost through and you mustn't talk to anybody about it, 88 00:06:53,040 --> 00:06:57,150 but you have to transfer 2 Mils to the Seychelles " 89 00:06:57,150 --> 00:07:01,260 and then folks do that and those Mails work 90 00:07:01,260 --> 00:07:05,650 a litte with authority, trust, haste and pressure and guide people 91 00:07:05,650 --> 00:07:11,949 to do what they shouldn't. 92 00:07:11,949 --> 00:07:15,250 This might sound funny in the first moment but when you talk to 93 00:07:15,250 --> 00:07:19,240 someone that fell for it, they are really rattled, because they know 94 00:07:19,240 --> 00:07:22,470 that it wasn't smart and damaging for the company. 95 00:07:22,470 --> 00:07:28,200 and that's not that entertaining anymore. :( 96 00:07:28,200 --> 00:07:34,740 Let's get back to entertaining stuff: The authentication. A thing that many folks 97 00:07:34,740 --> 00:07:38,680 have problems with, is their password and the problem is 98 00:07:38,680 --> 00:07:43,340 that they only have one and it lingers in such a collection 99 00:07:43,340 --> 00:07:48,830 you and everyone has them and 100 00:07:48,830 --> 00:07:55,410 you can look up you passwords, i.e. 23bonobo42, Tim Pritlove, so on 101 00:07:55,410 --> 00:08:03,490 The beauty of these lists: even WE who should know better are in those lists. 102 00:08:03,490 --> 00:08:06,910 When you enter my E-Mail adress in "haveibeenpwned" 103 00:08:06,910 --> 00:08:11,130 - a website where you can check if you've been inlcuded in a leak 104 00:08:11,130 --> 00:08:15,990 you can also find ME. So, i will explain how that might have happend. 105 00:08:15,990 --> 00:08:22,470 The thing that makes me furious about this, is that since there have beeen 106 00:08:22,470 --> 00:08:26,080 computers we have never really done anything against this password problem. 107 00:08:26,080 --> 00:08:30,009 We tell people: Ok your password shouldn't be guessable, best case random, 108 00:08:30,009 --> 00:08:33,950 whithout any system. It should be as long as possible, best case not a word 109 00:08:33,950 --> 00:08:40,089 And it should be different everywhere. And NOBODY does that. 110 00:08:40,089 --> 00:08:44,250 Recently i went to the dentist and when you talk with him, he's always like: 111 00:08:44,250 --> 00:08:47,389 Yeah, floss morning, lunch, evening and everytime and so on 112 00:08:47,389 --> 00:08:51,390 "yeah, yeah, first you change all your passwords and then we can talk about 113 00:08:51,390 --> 00:08:55,214 that" [laughter] 114 00:08:55,214 --> 00:09:02,710 [applause] and yeah i've done that 115 00:09:02,710 --> 00:09:06,080 116 00:09:06,080 --> 00:09:09,840 117 00:09:09,840 --> 00:09:12,550 118 00:09:12,550 --> 00:09:15,960
