[00:03.630 --> 00:10.370] Yeah, no. I think we're gonna have to do it tomorrow. We'll do it tomorrow. I got to go. [00:10.370 --> 00:18.310] I got to go. I'm giving a presentation at DEF CON. The cool thing is I'm recording it now [00:18.310 --> 00:23.230] and it's going to be presented 20 years into the future in 2020. Isn't that cool? [00:23.410 --> 00:26.190] All right. All right. I'll talk to you tomorrow. All right. Bye. [00:28.430 --> 00:36.150] Yeah. Hi, everyone. It's good to be here. I'm coming to you from the past to talk about the [00:36.150 --> 00:46.210] 90s and how pen testing really came from the hacker community and just wouldn't really be there [00:46.800 --> 00:53.850] if it wasn't for the hacker community. So I have some slides and I'm gonna share my screen here [00:53.850 --> 01:02.430] so we can we can see them. All right. Great. I hope everyone can see the slides. [01:03.610 --> 01:12.770] So, yeah. I'm happy to be here. My name is Chris Weisoppel. Some people might know me as [01:12.770 --> 01:21.670] Weld Pond. And I'm gonna talk about how red teaming was born from the hacker community. [01:24.210 --> 01:31.950] Some of you may have seen this picture. This is a picture of the group of us from the Loft, [01:31.950 --> 01:40.330] which was a hacker group that I'm part of. And we actually got these t-shirts made up [01:40.330 --> 01:45.650] to commemorate the event, Feds Love Loft. But we testified at the Senate. It was a little [01:45.650 --> 01:52.970] controversial at the time. We were the first hackers to talk about computer security and try [01:52.970 --> 01:59.870] to help the U.S. government understand what was going on. I don't know if you can see our [01:59.870 --> 02:05.610] placards there in front of us, but they have our hacker names, not our real names, [02:05.610 --> 02:09.550] which I thought was pretty interesting. They let us testify with our hacker names because, [02:09.550 --> 02:15.930] of course, back in the 90s, it was kind of risky to be called out as a hacker with a hacker handle [02:16.930 --> 02:22.230] and posting about vulnerabilities and things like that. So we didn't want to risk our day jobs [02:23.050 --> 02:29.990] we were all, a lot of us were in IT. And, you know, if you said bad things about a big vendor, [02:29.990 --> 02:38.070] it might be bad for you and your job. Unfortunately, or fortunately, I'm not sure [02:38.070 --> 02:46.110] what, but, you know, our pictures were posted with our, it was posted in the newspapers the next day [02:46.110 --> 02:52.550] and people at work kind of knew what we looked like. So the jig was kind of up that we did this, [02:53.170 --> 03:01.530] that's me there. And here's a little different. I've made it a little bit shorter. But, you know, [03:01.690 --> 03:08.510] a lot of people say, you know, how did this happen? How did you get there? And it really was, [03:09.250 --> 03:17.070] you know, doing things the hacker way, you know, reverse engineering, exploring, [03:18.270 --> 03:25.130] looking at hosts and networks, but we did it on our own machines. And we did it in order to [03:25.130 --> 03:32.390] publicize the insecurity in software and hardware and took on a really kind of a consumer advocacy [03:33.290 --> 03:42.270] approach. And I think while making trouble for vendors, a lot of other people saw the benefit [03:42.270 --> 03:51.310] of what we were doing. And that's how we got invited to go speak at the Senate. And famously, [03:51.310 --> 03:57.150] Mudge, who's there next to me, said we can take down the internet in 30 minutes. And we were [03:57.150 --> 04:06.470] talking about BGP vulnerabilities, which are still a problem. BGP hijacking is still definitely an [04:06.470 --> 04:13.470] issue a few years later. But I want to go back to sort of the beginning of sort of computer [04:13.470 --> 04:21.850] security. And when I go back to the beginning of computer security, I think of, you know, [04:21.850 --> 04:30.550] the Orange Book. This was a book that talked about design and security features, authentication, [04:31.090 --> 04:38.630] encryption, auditing. It really talked about security features. And the book was kind of [04:38.630 --> 04:43.670] made famous in the hacker community because it made an appearance in the movie Hackers. [04:44.170 --> 04:49.830] But it really was the way that people thought about computer security, you know, in the early [04:49.830 --> 04:56.910] and even in the mid 90s. It was all about security features. There's nothing in here about bugs in [04:56.910 --> 05:03.790] code, right? And we all know that that blows a hole right through any security feature. So there [05:03.790 --> 05:10.810] was a huge part of building secure systems that was completely missing until hackers started [05:11.630 --> 05:19.210] exploring and probing things. The other big way people thought about computer security was CERT, [05:19.210 --> 05:25.410] which was formed after the Morse worm. And in the early 90s, CERT said, you know, we'll start [05:25.410 --> 05:30.750] taking a look at these vulnerabilities. You know, if someone finds a vulnerability, send it to CERT. [05:30.750 --> 05:37.410] We'll understand it. We'll look at it. We'll talk to the vendors and we'll try to get them to fix it. [05:37.610 --> 05:42.730] But one of the things we found at the loft is when we first started dealing with CERT, if we found [05:42.730 --> 05:49.110] vulnerabilities, that we would send it to CERT and it would just become a black hole. We didn't know [05:49.110 --> 05:55.470] if the vendor fixed it, if they fixed it in a silent fix. The general public didn't know about [05:55.470 --> 06:01.590] it. So there was no way for them to know that they should be patching. And there was sort of no [06:01.590 --> 06:07.990] consequences for vendors who wrote, you know, buggy, insecure code because the general public didn't [06:07.990 --> 06:13.250] know about it. It was just something between CERT and the vendor. And, you know, I think that was [06:13.250 --> 06:19.970] pretty broken until hackers basically, you know, did an end run around that whole model. [06:21.130 --> 06:30.610] In the early days, there were some hackers that tried to start companies. The earliest company [06:30.610 --> 06:37.590] that I know of is a company called ComSec Data Security. And here's actually the press release [06:39.030 --> 06:45.650] from 1991. So the contacts here are Scott Chason and Chris Goggins, two of the founders [06:46.390 --> 06:52.530] of ComSec. And they're quite proud to say that they're comprised mainly of the now-defunct [06:52.530 --> 07:00.090] computer group, the Legion of Doom. And they plan to offer full-scale security package [07:00.090 --> 07:07.010] to private industry. I don't know if people remember Legion of Doom, but, you know, several [07:07.010 --> 07:15.930] members actually went to jail for CFAA violations. So, you know, maybe not the best group to be [07:15.930 --> 07:21.890] saying this is the basis of our company. But what they were saying also is they were [07:21.890 --> 07:26.630] bringing a fresh approach to the security consulting and the corporate marketplace. [07:27.990 --> 07:34.950] That they know how systems are compromised and what actions need to be taken to secure them. [07:34.950 --> 07:41.530] So this was actually a totally new thing. They were really kind of pioneering here, saying that [07:41.530 --> 07:47.710] they know how systems are compromised. And so that's the fresh approach. Isn't that amazing [07:47.710 --> 07:55.350] in 91 that that was brand new? And I have to applaud them for, you know, pioneering in the [07:56.530 --> 08:02.510] industry here. But in the press release, I thought this part was actually pretty interesting. They [08:02.510 --> 08:07.770] said that they were aware of the possible shock wave among the hacking underground over this [08:07.770 --> 08:13.410] venture. The firm maintains that they are security consultants and not informants or [08:13.410 --> 08:18.590] hacker trackers. We're not going to go after people. We are going to ensure that no one, [08:18.590 --> 08:24.890] hacker or corporate spy, can compromise the security of our clients' computers. So, you know, [08:24.890 --> 08:31.950] there was this idea that, like, if a hacker worked for a corporation, it was sort of narking, right? [08:31.950 --> 08:38.970] The only reason you're there is to, you know, tell them about the other hackers that were out [08:38.970 --> 08:45.110] there that you knew about from underground bulletin boards and mailing lists and bridges and things [08:45.110 --> 08:49.810] like that. And they were claiming that's not what they're doing. That's not what they're doing. But [08:49.810 --> 08:56.190] that was definitely a concern back then, this whole, you know, can the hacker community trust [08:56.190 --> 09:00.770] someone who goes into corporate world? So it really kind of went both ways. [09:03.210 --> 09:14.510] There was an interview afterwards by ISP News, and I thought this was actually kind of interesting. [09:15.670 --> 09:20.750] ISP News was saying, given where you're coming from, why should a potential client trust you? [09:20.750 --> 09:26.050] And the CG here is Chris Goggins, one of the founders. He says, I know it's a natural question, [09:26.050 --> 09:33.330] just the very nature of creating a company should project an image that we are trying to come out [09:33.330 --> 09:37.590] of the shadows, out of the underground. We're saying, look, everybody, we've been doing this [09:37.590 --> 09:44.950] for a long time. Now we want to help. And, you know, ISP News says, I'm sure you understand the [09:44.950 --> 09:51.050] natural suspicion that people have. And Goggins says, no, that's what I don't understand. If we [09:51.050 --> 09:55.490] at ComSec were out to compromise information from an existing company's computer network, [09:55.490 --> 09:59.610] we wouldn't have incorporated. We could have done that, and someone else could have [09:59.610 --> 10:04.470] already done so. Then the information would be available from one hacker to another. [10:04.470 --> 10:11.090] So he's really trying to say, hey, you know, we understand that people are going to be skeptical. [10:12.570 --> 10:20.370] But, you know, you can trust us. Unfortunately, ComSec didn't go very far. It was just too early. [10:20.370 --> 10:26.750] They couldn't get any customers. And, you know, some things had to happen between 91 [10:27.310 --> 10:33.410] and the late 90s before people could start to trust hackers and hacker techniques [10:34.550 --> 10:43.370] to secure their systems. One of the big seminal papers, and something that was very seminal for me [10:43.370 --> 10:50.090] when I was starting out doing computer security, was this paper by Dan Farmer and Witte Venema in [10:50.090 --> 10:56.490] 93. So just a couple years after ComSec. And they wrote this paper, improving the security of your [10:56.490 --> 11:02.590] site by breaking into it. And they published this as a paper. I'm not sure if it was published in [11:02.590 --> 11:12.550] USENIX security, but it was an academic paper that was in the form of something that a government [11:12.550 --> 11:19.110] security person or a corporate security person could kind of understand. It wasn't all shady, [11:19.370 --> 11:26.550] like Frack Magazine, etc. And basically, it just talked about, you know, look at the way that [11:26.550 --> 11:33.650] attackers are breaking into networks, collect all of those things together, and try them on your own [11:35.090 --> 11:42.950] network. Weak passwords, probing open ports, try exploiting trust, [11:42.950 --> 11:49.590] exploit known bugs. Imagine that, exploiting known vulnerabilities to see if you have them. [11:49.590 --> 11:55.870] This was a new concept in 93. And then they talked about locking down networks based on [11:55.870 --> 12:03.570] understanding how hackers were and attackers were going after networks. [12:04.770 --> 12:11.010] And then, a little bit later, well, not in the first one with Crack, but a little later, [12:11.010 --> 12:19.550] these hacker tools started to show up. Really, the first hacker tool that was sort of, you know, [12:19.550 --> 12:27.550] well known and well available was Crack by Alec Muffet. Came out in 1991. And his whole idea was [12:27.550 --> 12:35.450] do a dictionary attack, or a brute force attack on Unix passwords. Seemed like a reasonable thing [12:35.450 --> 12:44.450] to do. If attackers were guessing passwords, why not guess them first? And just do it right on the [12:44.450 --> 12:51.110] password file, the encrypted passwords. Seems to make complete sense now. But back then, this was [12:51.110 --> 12:59.530] considered only an attack tool. Why would a legitimate person use this kind of tool? [12:59.950 --> 13:07.310] Randall Schwartz was an admin at Intel that was actually fired and was charged with a felony [13:07.310 --> 13:15.770] for using Crack on the systems that he administered purely to tell the users of his system that they [13:15.770 --> 13:24.750] should pick a stronger password. Thankfully, later, the felony was, charges were reversed [13:25.650 --> 13:31.150] after a few years, but not so good for Randall Schwartz's career in the beginning. And of course, [13:31.150 --> 13:38.350] we know now, with Have I Been Honed? and lots of different things, [13:38.350 --> 13:43.690] figuring out if people are reusing passwords or weak passwords is critical. [13:44.730 --> 13:51.650] Satan was a tool created by Dan Farmer and Weetzie Venema a few years after they wrote their paper, [13:51.650 --> 13:59.490] basically automating the techniques that they said. So let's try all those vulnerabilities. [13:59.490 --> 14:04.790] Let's target all those misconfigurations. Let's automate the process of finding these problems [14:04.790 --> 14:11.850] on your network. Guess what? Dan Farmer got fired from his job at SGI for releasing this tool. He [14:11.850 --> 14:18.210] actually got fired for writing a tool, which is now a multi-billion dollar industry from the likes [14:18.210 --> 14:27.090] of, you know, Rapid7 and Qualys and Tenable. Dan got fired for pioneering the idea of network [14:27.090 --> 14:33.210] scanning for vulnerabilities. A little bit of trivia there, that logo on the right [14:34.230 --> 14:43.830] is the logo of Satan. And it was actually sketched by Neil Gaiman, the author of Sandman. So Dan was [14:43.830 --> 14:50.250] friends with him. And then the final tool I wanted to mention was Netcat by Hobbit, came out in 96, [14:50.250 --> 14:54.370] really as this network Swiss army knife. I'm sure everyone has used Netcat. [14:55.630 --> 15:01.960] Didn't do anything except set up connections and send data to those connections. [15:02.170 --> 15:09.690] I ported it to Windows and it actually turned out that that started getting flagged as something [15:09.690 --> 15:16.830] that was malicious code by antivirus. So if you actually wanted to use that to scan systems and [15:16.830 --> 15:22.460] test systems, you had to make sure that you didn't run a file of antivirus. So there's a lot of [15:23.560 --> 15:31.420] misunderstandings in the early days. And hackers created the first real true information [15:32.600 --> 15:39.440] sources about bugs in software, vulnerabilities, bug track with its full disclosure policy, [15:39.440 --> 15:45.280] famously went around what cert was trying to do. It was a place where people could publish [15:45.280 --> 15:52.760] information. If vendors weren't listening to you, you could just publish it publicly. And it [15:52.760 --> 15:59.220] was a place where like-minded security people could find that. Really radical in the beginning [15:59.220 --> 16:07.420] years. It was actually created in 1993 by Scott Chason, someone who, one of the founders of ComSec. [16:07.420 --> 16:14.040] So I think we have a lot to thank Scott Chason for, for pioneering and pushing the limits. [16:14.600 --> 16:21.360] He was also a, one of the early editors of FRAC, along with Chris Goggins, was one of the early [16:21.360 --> 16:27.800] editors of FRAC, which, you know, started in the late 80s and still goes today. Very popular in the [16:27.800 --> 16:33.660] mid 90s. Issues coming out on a monthly basis, all kinds of exploits and tools. And of course, we all [16:33.660 --> 16:38.480] know about DEF CON as a place where people can gather and give presentations. And that's, that's [16:38.480 --> 16:44.880] where we are here today. The first computer security presentations about sort of real security [16:44.880 --> 16:53.600] were created by hackers. And the other big change I think we saw with hackers entering the realm [16:53.600 --> 17:02.220] here of computer security was they made computer security a participatory sport. Capture the flags [17:02.220 --> 17:08.960] became a way to learn, learn by doing, learn by training with your adversaries, learn from your [17:08.960 --> 17:18.280] adversaries and make it fun. Right? Up until then, security was sort of set it and forget it. You [17:18.280 --> 17:24.580] know, maybe there was an audit by a, an audit and accounting firm to make sure you had, you know, [17:24.580 --> 17:29.980] passwords turned on and you had logging and all that. But it was very static. It was very set it [17:29.980 --> 17:37.400] and forget it and wait for the attackers to come. Where the hacking community really birthed this [17:37.400 --> 17:44.120] notion of the pen test and the red teaming and adversarial, the adverse, bringing in the adversarial [17:44.120 --> 17:52.740] nature for, for securing systems. And we know that that's made a huge, huge difference. [17:54.740 --> 18:01.900] So I was a member of the loft starting in 93. And, you know, four or five years later, we said, hey, [18:01.900 --> 18:07.280] you know, this is all fun. We're releasing things and that, but, you know, maybe this could be a [18:07.280 --> 18:12.900] business. Maybe we could actually do consulting. Maybe we could sell software. And actually in 97, [18:12.900 --> 18:17.860] we started selling loft crack. And we thought about, you know, maybe this could be a full time [18:17.860 --> 18:26.260] gig. So let's try, let's try consulting. And we knew about CommSec back in 91. And they, we knew [18:26.260 --> 18:32.480] that, you know, the loft was a known hacker group and we used our hacker names, but you know, maybe, [18:32.480 --> 18:39.260] maybe, maybe times have changed. Maybe we could have a go at this. And so we tried our hands at [18:39.260 --> 18:45.220] consulting. And one of the ways we did this was we found a local consulting company in the Boston [18:45.220 --> 18:53.700] area. And we talked to them and we said, you know, maybe you should start a consulting business. [18:53.880 --> 19:03.860] And the loft could, you know, be your security consulting business unit. And so we started [19:03.860 --> 19:11.520] talking to them about coming on as employees. And we said, there's no better way for us to demonstrate [19:11.520 --> 19:19.960] what our capabilities are than to try to hack, try to hack your company, right? Let's do a full-on [19:19.960 --> 19:30.700] penetration test of your company. So we talked them into letting us do this. We did it pro bono, [19:30.700 --> 19:39.620] you know, because we were trying to explain to them the value we had. So we did that. And we [19:39.620 --> 19:44.940] were actually negotiating with them at the time, right? We were negotiating with them saying, [19:44.940 --> 19:50.000] you know, what would our salaries be? What would the business look like? You know, [19:50.460 --> 19:57.940] what would be the parameters around us coming to work at your company? [19:58.900 --> 20:10.860] And we just did, we did a no-holds-barred, full-spectrum, you know, voicemail, wireless, [20:10.860 --> 20:17.840] physical security, internet connection, you know, you name it, it was on the list. [20:17.840 --> 20:27.040] It was in scope. We actually didn't do any email social engineering or voicemail social [20:27.040 --> 20:35.760] engineering. But we did do things like physically penetrate in order to do things like, you know, [20:35.760 --> 20:45.840] see what was in the trash and things like that. So here's the cover page of our security audit. [20:45.840 --> 20:50.680] We went, we didn't go by the loft, we went by LHI Technologies. We took the loft-heavy [20:50.680 --> 20:57.180] industries and made it LHI Technologies. And because we were doing some consulting, [20:57.180 --> 21:01.660] selling some software at the time, and that was a part of the loft history where we were [21:01.660 --> 21:08.340] actually sort of becoming a company. And we did this between August 20th and September 8th, [21:08.980 --> 21:19.800] 1997. It was a completely black box test. And, you know, we use a combination of tools and [21:21.280 --> 21:27.940] network probing. I've blanked out the name of the company. It's been a few years, but [21:28.500 --> 21:36.460] just, you know, make sense to keep them confidential. Security in 1997 was a lot [21:36.460 --> 21:44.340] different than it is now. So just if I look, we look at the executive summary here, [21:44.340 --> 21:50.420] you can see that from the internet, we were pretty much able to totally own everything. [21:50.420 --> 21:58.760] All these critical corporate systems, Oracle databases, got corporate credit cards, voicemail, [21:58.760 --> 22:05.720] the network routers, the dial-up systems, personal email, their intranet site. [22:06.760 --> 22:14.380] So basically total ownage. And we did this without any kind of inside accomplices, [22:14.380 --> 22:21.300] no previous knowledge. Completely, completely black box. So, you know, I could do a whole [22:21.300 --> 22:25.940] presentation on the gory details of this, but I just wanted to highlight a couple things which [22:25.940 --> 22:34.640] I thought were interesting. Things you don't always see in a pen test. So one is, you know, [22:34.640 --> 22:42.420] one of the first ways we got in was through the web server. And if anyone had been doing [22:42.420 --> 22:52.520] hacking in 1996, you probably heard of the PHF vulnerability. It was a CGI bin that came [22:52.520 --> 23:00.080] pre-installed with Apache. And it had command injection, right? So you could just [23:02.580 --> 23:11.160] put a delimiter character in there and put your command. Pretty basic. But of course, [23:11.160 --> 23:18.220] you know, Apache should be running as its own user, right? It should be running as HTTPD, [23:21.320 --> 23:26.000] shouldn't allow you to compromise the system through this vulnerability, right? Maybe you [23:26.000 --> 23:31.880] could get... it's basically an information leakage if permissions are set correctly. [23:31.880 --> 23:39.180] But we were poking around and we actually saw that someone didn't set the permissions on [23:40.460 --> 23:48.880] HTTPD.conf file correctly. So the configuration file shouldn't be owned by the HTTPD process [23:49.440 --> 23:54.940] because, you know, then any code that executes from the web server could change the configuration [23:54.940 --> 24:00.860] and guess what part of the configuration of the server is? It's what user the server should run [24:00.860 --> 24:09.940] as. So we use this command injection to edit that file and change it so that the next time [24:09.940 --> 24:17.120] the server came up, the web server came up, it would be running as root. Nice little technique [24:17.120 --> 24:22.560] there. But then we did uptime on the system and we saw that the system had been running for over [24:22.560 --> 24:31.900] 100 days. And, you know, we tried DDoSing it. But, you know, we basically had to wait for someone [24:31.900 --> 24:36.840] to reboot the server. And so we didn't think we were going to go... we weren't going to get in [24:36.840 --> 24:42.020] this way. We started probing some other systems and actually found some other vulnerabilities [24:42.900 --> 24:50.300] and were able to get in. But a few days later, I was listening to the news [24:51.060 --> 25:00.860] and I actually saw that there was a manhole explosion in Cambridge where this company was [25:00.860 --> 25:09.860] located. And unfortunately, an employee of the power company actually died in the manhole [25:11.020 --> 25:19.380] explosion. But it downed power in Cambridge for five hours. And after this happened, [25:19.380 --> 25:27.440] I started started probing, you know, the system and started looking at their web server. And it [25:27.440 --> 25:32.800] was up after an hour, it was up after a couple hours. So they obviously had backup. But after [25:32.800 --> 25:40.940] about three hours, the system went down and they didn't have enough backup for this five-hour power [25:40.940 --> 25:47.380] outage. And when the power came back up, it rebooted and we were now doing command execution [25:47.380 --> 25:53.400] as root. So I just thought that was a little bit... I had never come into a situation like that before [25:53.400 --> 25:58.800] in a pen test, but you just never know how things are going to go and what's going to go your way. [26:00.020 --> 26:06.300] The other thing I thought was pretty interesting was we, you know, looked at the voicemail, [26:06.820 --> 26:13.520] the voicemail systems. And you can see there on the left, the extension, we have the username in [26:13.520 --> 26:19.400] the middle. I've grayed out some of them. And then the password on the right. And you can see [26:19.400 --> 26:25.020] the new employee voicemail box gets a 1234 password. And you can see that some people never [26:25.020 --> 26:34.040] changed it, like IT and facilities service line was 1234. The travel line was 1234. Directions [26:34.040 --> 26:39.440] was 1234. But there's some other accounts on there where the extension and the password are the same, [26:39.440 --> 26:46.380] 4069. And if you look down, there's 18629, where the extension was the same as the password. [26:46.940 --> 26:54.740] That actually happened to be the vice president that was negotiating with us at the time about [26:54.740 --> 27:02.560] joining the company. And we sort of listed out what we were expecting for salaries, benefits, [27:02.560 --> 27:11.060] how we wanted the jobs to work. And one of the things we really wanted was we wanted that [27:11.840 --> 27:17.160] step van, or I don't know if it was a bread truck or whatever, that was in sneakers. [27:17.160 --> 27:25.500] We wanted a sneakers van so that we could outfit it with electronic equipment to do wireless [27:26.220 --> 27:33.680] and surveillance and have the mobile hacking unit. It looked totally awesome. I think everyone [27:33.680 --> 27:40.680] who watched sneakers loved that. We put in that we wanted that. And we heard on this voicemail, [27:40.680 --> 27:45.620] so we captured a couple of voicemails as evidence that we were able to get in the account. [27:46.040 --> 27:53.760] And one of the voicemails was talking about those loft guys. And he said, [27:53.760 --> 28:00.300] these guys want an effing Winnebago. And they were not happy with us. They thought we were [28:00.300 --> 28:06.500] asking for the world. Sort of just didn't understand what we were going for. [28:07.040 --> 28:13.280] So you don't always have a situation where you're negotiating with your potential future employer [28:13.980 --> 28:19.080] while you're doing a no-holds-barred pen test with your get-out-of-jail-free card, right? [28:19.080 --> 28:27.460] So, again, another bit of an interesting situation. But, you know, we didn't end up [28:27.460 --> 28:33.640] joining there. And a couple years later, the loft ended up joining a startup company [28:33.640 --> 28:42.600] called At Stake, which just did information security consulting. And I'm sure some of you [28:42.600 --> 28:50.660] have heard of At Stake. This was an article from January 2000, where, you know, the way the news [28:50.660 --> 28:57.400] looked at it was using good hackers to battle bad hackers. If you have a murky past and doubt you [28:57.400 --> 29:05.700] could become a dot-com millionaire, think again. And I thought, you know, what a change from [29:05.700 --> 29:15.340] the 1991 with ComSec, really not being thought of as credible. So a lot of things had to happen [29:15.340 --> 29:25.300] over the 90s for really us to join At Stake and be perceived as a legitimate company. And [29:25.960 --> 29:35.240] so that's my story. That's my story from 2000. I hope that you enjoy this in 2020. [29:36.540 --> 29:43.000] And here's my contact information. There's this thing called Twitter is going to get invented, [29:43.000 --> 29:49.020] I think. And I'm going to found this company called Veracode in 2006. Just some of my future [29:49.020 --> 29:54.640] plans. So I hope you enjoyed it. I'm going to join on the Discord, which is another technology [29:54.640 --> 30:04.600] that's just going to be invented. And hopefully, we can chat. So bye-bye, everyone.
