Andres Jõgi & Dadash - We have Mythos at home

Heat. Heat. [music]

[music]

So, good evening, Talin. It's time for your mandatory sponsor segment, [laughter] and we are the final bosses before beer and the party. And unfortunately for everyone around here uh the jump ahead button it's not available since you're listening to us live. So I am Dad Kh senior product security engineer and I'm Andrei offering no services to the same team [snorts] and um yeah as you just heard uh we work for the road rage company. Uh so the green logo with the white letters um I think all of you have seen these logos around Talin. So if you're from around this part of Europe you might know about this company. So it's a sort of famous but

what are we famous for in addition to road rage? So actually we consulted with our threat intelligence providers. Um so ulet and uh other Estonian [laughter] uh newspapers and we found out something that was very surprising to us as well. So we are very famous for reinventing the bicycle. So while previously when you ordered or wanted to rent a light mobility vehicle, you could only get a scooter, right, which has an electric motor, so no training for you. Then we rolled out the electric bikes, you get a bit of training, but still not enough. But now you rent a bike and you can do training. I would have to pay for that. [laughter] [snorts] And uh yeah, we're also number

one scooter provider for this particular hive of bees. And uh yeah, we do all of this at a significant scale. So we actually have some numbers around here as well. So we have more than 200 sorry yeah 200 million lifetime customers some of which are not even peace. We have 4.5 million partners. uh so you know the taxi drivers restaurants taxi company owners uh etc etc [snorts] and we operate in more than 50 countries and uh keeping all of this operation and platform running is 4,000 people >> and 600 of them are engineers who are doing more than 500 deployments and serving to more than 600 billion HTTP requests per day. >> Yeah, but enough of the nerd talk. So it it

takes a lot of effort to keep this platform secure. So we have a small information security team of approximately 20 people who is doing everything from digital forensics, incident response. We are doing secure software development life cycle sort of ensuring that it works. We are trying to improve our cloud security posture and of course everyone's favorite we also do audits and not only ISO and uh PCI uh but also all the interesting local regulations and I'm not talking about goods here [snorts] but also like uh whatever they do in some of the African countries or Romania it it's a very wide variety >> and sorry for the interruption by the way Julia is doing like taking care of

audit part and another room, another stage. Yeah. [snorts] So, but uh working in cyber security uh very small part of our job is to keep ourselves up to date with whatever is happening with the cyber sec and threats. >> Uh nowadays it's like AI hacking into this, hacking into that rather than like rainbows glooms. >> Yeah. So it has been looking from the early this year something like this. So we had open glove. So let your agent out of the box have it run its own social media account. Give it access to everything. Then you have all the AI frontier labs sort of claiming that the AI is hacking into everything and they're not at

fault. It's just so intelligent. And of course, Entropic started with it that the AI is too powerful to be released. And yeah, miss me with that crap. So this was sort of our opinion of all of this. So as uh Lo Star Wars once said, talk is cheap. Show me code. Well, code is cheap as well. So show me what it does. And to be honest, especially early this year during audit season, we had more urgent problems to take care of because we had to convince our good friends in engineering to sort of stop adding new features for a moment and fix some old stuff for compliance reasons. And when is dark mode >> [snorts]

>> error? So, and and this is sort of how our slack look like. So 99 problems and AI ain't one wasn't yet. So we got like I saw it six seven observation there's an issue. So the vulnerability management is sort of slow [snorts] unwieldy too manual inefficient so what's the situation? So we currently have llinters, compiler checks, image repository and image scanning and like bug bounties, pentests, everything around that. Yeah. But uh what was sort of recommended was that like handling all the findings was sort of manual [snorts] and inefficient. So it we take a look at the list uh routinely and then sort of tag people and pull them until they start fixing stuff. And what was

sort of recommended was, hey, can you maybe fix something during development? So have some preventative guards instead uh or more efficient preventative guards. And of course as a manager, the dash fix it. So I believe they are probably asking for regular SAS solution that would just like exist in your CI/CD pipeline and like just scan the code find the vulnerabilities highlight them and like we have bunch of options such as sim grip iikido or golden shiny boy github advanced security >> okay I mean let's do it then >> but there is a problem >> what uh problem with the solutions that they are charging per seat so you are not getting the value uh based on what are

based on what are you paying but you are basically paying for every single engineer that's just having an access to the solution and they are pretty expensive to tune okay so if I look at the budget so we we can only do partial coverage and we also have non-engineer coders so sort of everyone's an engineer not necessarily in production but doing their own little scripts So that would also inflate the price. Okay, cancel that. >> Now what? So we do the next testing obviously. So AI of course. [laughter] [snorts] >> So let's sort of surf the waves. Let's uh on board the hype train. Uh I I think our AWS uh account manager told us

something about project classing and then they can give us access. So of course uh we went to our head of infosc and asked him hey dharma can you please can you please please please please please please please please please please please please please please get us access to meet us maybe it's good so [snorts] and this is how I imagine the conversation went so hello dear account manager how are you doing how are the kids can we please get access to mitas account manager is writing freedom noises US government has suspended access to meet us and fable. So access denied. [snorts]

Oh this guy again Andress I have an idea. So we are going to build our own SAS inside using cheaper models and we are going [snorts] to scan the codebase and replace all these solutions ourselves. the dash, you know how to crack me up. So, what could possibly go wrong? Let's just wipe security. I mean, [laughter] great. So, what what you want me to do is to open [snorts] CL and go, hey, Clot, implement security, but do it securely. [laughter] No, hear me out. [snorts] So what we can do is we already get the pull request triggers and it's containing everything we need the code and the difference and we're going to feed it into LLM uh and ask LLM to check

for security issues within the code and get the output put it into the feedback loop like PR comments and log everything into the Google Sheets. H Google Sheets. That's a serious security tool. Maybe let's do Excel instead. Okay. [snorts] So, can we should we So, can we replace what is basically the deterministic rule-based engine with like pretty random LLM wipes based review, right? We will not get repeatable results and we will end up being vulnerable to prompt injections. But my dude, it's more nuanced than that. So let me explain you how regular SAS works. You have the code that you are feeding into the tool that has regular rules like such a simple reax and you are creating alerts based

on those like reg x matches and you have a fancy dashboard usually that's showing auditors whatever they need. Okay. But how do you get the rules into the system? How does it know what is secure and what is not? So you get by default rules out of the box when you get the solution itself and you also spend a lot of time and resources to tune these rules, switch them on or off. >> Okay. Okay. So what are you trying to tell me? So SAS rules may seem like deterministic but you having them in a correct time correct place is pretty much random and it's totally depending on the your security engineers mood at the day that if they want to enable the

rule. Okay. Okay. Actually I think I have seen this before. So this is how we do it in security. So we get a new shiny tool in this case static analysis tool. We do bare minimum setup because we don't have much time and then we deliver thousands or hundreds of unrested findings to developers who after the first few false positives will sort of ignore us forever. And that's almost as bad as not having a security team at all. [laughter] Okay. Okay. Okay. Okay. I I'm starting to get you now, but let me just consult my boss. So ah we have to do AI now anyway because that's the cool thing to do. So it's yeah okay like [laughter]

let's do something cool. So okay I will authorize it. So I will postpone the road map. I will think about >> hey Andreas I have the MVP ready. >> Oo w [laughter] to looks looks kind of sick but how do we know it works? So shall I spin up that vulnerable web application? >> No >> extremely vulnerable web application. Not at all. >> Chin and chew shop. >> I don't think so. >> So, what do you want us to do? >> So, we're going to test in production like real men. And [laughter] there's a reason for that. [snorts] AIS are trained on public information available outside. So, all these applications have like multiple walkthroughs on the

internet that AI has already been probably trained on. And we don't trust that AI can actually find the issues but it would probably recall its like memory and use find the vulnerabilities claim to find the vulnerabilities and that's why we decided to move forward with the testing ourselves. Yeah. And we also don't have obviously vulnerable code in production. We have nonobviously vulnerable code. Right. So but uh how do we know it's actually useful? Because we don't know about all the vulnerabilities yet. So what are we going to do that we already have gathered more than thousands of vulnerabilities over the years through the pentests internal finding public bug bounty programs and etc. We are going to every single uh

quote that had the vulnerability do the get blame and find the vulnerable uh PR that basically introduced the vulnerability into the codebase and we will feed all this information to the AI and expect it to find these issues and find out if it could actually detect the issue before the PR actually hit the production. H okay. Okay. I I'll believe it when I see it. And it did actually work. So the dash will run you through uh some of the findings. These are simulated uh thanks to some vulnerability hunting workshops our lovely colleagues did. Uh but yeah, take it away. So for example, here you see a user password logged in as plain text on

every single login attempt. And uh just a disclaimer probably regular SAS tools you are using cannot identify this pattern like cannot resolve that the something is getting logged and it's sensitive especially if you have a typo uh rather than 2S 3S password if you're doing simple word match probably your regular SAS tool might have skipped it entirely and here you see the mass assignment vulnerability AI is like smart enough to identify the line of the code that is taking the user JSON uh user provided JSON payload and without checking uh trusting it entirely and using the update service to update user details which can contain if email verified is true or false or if user's password is

one two three or not and here you you see like predictable admin password which is generated and uh of course there has been unsecure random has been used and we are also leaking the time information through a API endpoint that AI could actually link these two issues together and chain it and give us the full risk of what can go wrong with this vulnerability. >> Yeah. And we are also able to draw a pretty cool graph. I didn't know that cloud can do that. [laughter] >> Okay, so at this point I'm pretty much a believer. But what about the money? So the tokens ain't free. So let let's do some math around here. So problem is uh how much does one run of

the prototype cost us? >> So Andreas, it's around $7.3 per execution with the Oppus 4.5 model >> which was the latest at the time. >> Okay. And if we run it on everything. So how many PRs do we do per month? [snorts] Uh in bold we do approximately 7 and a half thousand PRs per month. >> Okay. Okay. So that's like 55K per month which is ah 660K. So that's significantly more expensive than any of the tools we evaluated before. But I have a solution for that and so we are not supposed to use oppus 4.5. If we give enough context and information to cheaper dumber model, we can actually achieve the same result, even better

result based on our tests. And we're also going to enable the caching because single AI uh workflow is including like 11 12 back and forth discussion with the AI and our workflow which means we are going to save a lot of money through the caching and we are going to start with a very limited uh team. We are not going to like start scanning every single PR in the company but we will start with test team that would be happy to test our product in their workflows and we are also going to attribute the cost to the code owners since we already have this data stored in the very same uh place that we are scanning rather

than infosc being the cost owner uh we are going to attribute the executions to the owners so the people who are getting the scans actually going to pay for there. Okay. Well, to be honest, I do like it. So, as a result, this plan gives us slightly more fine grain control over how long of an experiment we run, how much tokens we spend, and it sort of helps me to ensure that we still have budget left over for the remainder of the year, right? So, I'm going to make an ex executive decision. Now, let's go. [laughter] But of course we did make a couple of adjustments before rolling this out for uh engineering white testing. So uh walk

us through how it's working at the moment. So in detail what are we going to do is just trigger a workflow from when whenever there's a new PR created in the the GitHub we are going to execute the workflow and send the diff and the context of the PR into our treasure assistant who is very cheap uh very dumb and we are expecting only two different answers from it either yes or no yes means that the scan is going to move forward and it would have multiple different specialist agents that's going to scan your codebase Uh they're covering identity and access management, injection and malicious code, logic, concurrency, resilience, which would have access to our internal security

guidelines and documentations. So they can refer to our internal rules and policies and easily highlight them. And this result is going to be fed into the validator agent which is going to challenge every single finding to make sure that we have least false positives. On top of that, it's confirming and rating every single finding severities. And once we have the findings, we are going to push them into the findings registry which is holding unique identifier for every single finding we have. And it will be stored in a database that where we have the history, ownership of the issues and etc. And of course we are going to show every single data in the dashboard where engineers

and security team can refer to and we would also have something to show to auditors. >> Okay. Okay. Okay. But uh so did you do everything uh based on our procedures, our boilies? So do you have an ADR? >> No. >> What about design doc? >> I forgot about it. >> Okay. Did you get it signed off by head of infosc? >> I'm on it. >> Uh y vice president of engineering. >> I was just writing to him. >> Have you consulted God? >> Uh almost. >> What about Satan? >> Uh I have a fancy animation right behind you. Maybe we can show it. >> Oh, this looks professional [laughter] as purely wipe. [snorts] >> Okay. Okay. But you also mentioned the

dashboard, right? So, can I see it? I forgot about it. CL, make a dashboard ASAP. Have the metrics, KPIs, everything. Make it fancy and almost forgot. Make it make no mistakes. Taa [snorts] that's pretty nice. And jokes aside, that's an actual screenshot. So we ran an experiment basically since July on volunteers from Bolt Engineering and uh as a total we found 266 findings. We even have severity ratings fromformational to critical. I don't believe in those but they are colorful [laughter] and even the false positive ratio is quite low because we are really bad at sort of measuring the signal whether it's false positive or not but it is there but what about money so as you can see on the screenshot uh

during this like entire testing period we have had 536 executions uh we are tracking every single penny uh that's costing to use the AI And we have spent in total uh bit more than $800 and we have spent more than a billion tokens and average cost for single run is around $15. Yeah, that's like six, seven times lower. Okay. Uh but how do we deal with the fake news, right? I mean false positives. We still want engineers to listen to us after running the tool, right? So I have a plan for that. What are we going to do is that apply the same logic that we have seen in the SAS into uh suppressing uh heristic based

outputs which basically we're going to have deterministic rules that's going to be applied to the findings that we are seeing frequently and we are for sure know that uh that is a false positive uh such as the same finding appearing in multiple places across the executions and we are going to write the rules and we are going to suppress every single like false positive like issue issues within the workflow. So findings won't even have those issues highlighted anymore. >> Okay. Okay. I I believe you. But to be honest, now it's sort of a good time to give you a very brief overview where our experiment has reached so far. So what our rule is good at is that it's

[snorts] ready enough that we can with minimal work on our side being involved run it on a random repository we have in our GitHub and uh there is minimal sort of setup from our side being required to make it work for bash typescript python java cotlin terraform coinfix some other random docker >> ys or or even brain It will probably work. The finding descriptions tend to be useful enough so that I can briefly sort of read over them and decide whether it's a true positive or in this context the false positive and the pricing is transparent. So the price we showed for runs this was the real number. It doesn't really cover the number of tokens that I spent to build

the damn thing, but it's still the runtime costs currently are quite low. And uh even if we don't have enough token budget to sort of have it run everywhere on all the pull requests, we can sort of mix and match and pick where we want to run it. And it isn't dependent on the team's headcount, but rather on the perceived value we see on our side. We still have issues right? What are they? [snorts] So one of the issues we are facing is that severities are totally based on the wibes of AI. So we tried like bunch of different solutions such as uh trying to make sure that we are going to uh convert the finding into

CWE or CVE or rated based on CVSS. We tried buck crowd VRTs but still AI is just like fighting against it and we have seen it multiple times that same issue is just like appearing as either critical or medium uh on the very same PR because uh AI sometimes is just like vibing it and applying the the best matching uh I would say category at the time it thinks and rerunning the tool or the solution on the same PR sometimes can be tricky because it can reproduce totally different results. So we have had seen the issues that engineer scanning the codebase three findings great let's them let's to fix let's fix them and like just the next scan uh brings up four

different findings that has never been identified in the first run. So uh we observed that if AI cannot find anything else to highlight, it's trying to dig deeper and find something actually to show you. And currently doesn't validate the fixes. We do not have the checks in place and we are blindly trusting engineers when they mark it resolved or false positive. It's being marked as resolved or false positives. But we are going to change it soon and we will make sure that if you do any change on the finding then AI is supposed to go and review it and confirm that the fix has been applied properly. >> Yeah. But as the news show us we are not

really the only ones who are trying to w our way into security or in this case insecurity. uh a couple of weeks ago, I think it was Esset Research sort of highlighted one of the Russian aligned APS uh and they have developed a sort of technique called guard breaker which is they create a malicious visual basic script as they always have done but they had instructions for creating nuclear weapons into the script as comments and so AI security tooling reading the script will refuse to analyze it further. because it has forbidden information. We cannot read it, master, we cannot read it. So are we vulnerable? [snorts] Uh yes and no and we have old but cold

method of peer reviews. Ah true. So as a code reviewer, if you see that the commit that your friend or colleague has asked you to review has instructions for how to synthesize MET or how to make nuclear weapons, please let your security team know. They're up to no good probably. [laughter] Yeah. But in general um our team despite all the dangers involved and all the headaches caused by agentic use of AI especially uh we have found the tools to be useful for ourselves as well. Uh and we don't even need to have the latest and greatest models. So you sort of have to know what you're doing. And uh our team has found LLMs to be useful in a

couple of scenarios. So we can sort of as a first quick response semi-automate playbooks. So we still write playbooks for humans. But if you are doing something for the very first time, you can sort of feed the same playbook to your clanker and have it sort of hold your hand while they're solving it first time. It's quite effective. But I think it makes the solving the new issue slightly easier for newcomers. Uh as a manager I have to do reporting but now I can sort of create quick and dirty dashboards from the spreadsheets from CSVs from SQL queries for the upper management very easily for whatever use case I have at hand. So if I need to

show the training completion for I don't know whatever cyber security training we're running and need for compliance in instead of sort of reporting the flat number the tool shows me I can actually go and merge the organization directory and I will show exactly which team has the best and worst completion rates. And as you might have realized from this whole presentation, we can also use it to sort of test new concepts quickly and either sort of fail or promote them quickly. But you still have to know what you are doing. So if you blindly the LLM then you will not get good results and still like we [snorts] have been able to utilize LLMs. We have not been able to

utilize NFDs or cryptocurrencies yet. So if you know about any cool use case, let us know. But I'm Andres. >> I'm Yeah. And you can chat to us about some of these topics later. Thrmo. [laughter] Thrmo. What is this? It It looks military. Great. It looks military great.

The guy delivers. We have [laughter]

Take that, US. [laughter] [snorts] >> Very cool. Uh, thank you very much for recommendation. Do we have any questions? I can see your hand up already. >> Thanks for a great talk. Uh, any chance of using local models for this? And second question, what's uh what the spin-off is going to be when you launch it for the public? Thanks. >> [laughter] >> So the first question I guess you can connect it to any LLM you trust. Uh it's like heavily based on how uh I would say skilled the model we are using. Uh we have tested cloud and we have tested open AI. So all of them >> local >> yeah local ones we have not tested

ourselves. Yeah we we are not running local AIS. >> Yeah not yet. Have you looked at the RAM prices? Do you even have GPU? [laughter] No, but I I think it will work well enough with the local models as well, but do you have enough hardware to sort of support your whole company for example? >> Thank you. Any more questions? >> Second question. Public lunch. >> Well, whenever given green light, do you want to buy it? [laughter] [snorts] >> Yeah. But you have earned uh access to meet us if you want. [snorts] >> There's a hand in the in the back there. Yep. >> We have more now

and thank you for very good presentation. A question regarding of of letting work out patches as well. Um >> yeah uh work on patches. >> [clears throat] >> The question is about the working on patches parallel. >> Yes. >> Uh yes, you can definitely do that. We are we already have this idea in the plan that uh we have got the suggestion from engineers multiple times that if we can actually generate proper fix remediation plan. Uh we should be able to feed this information into the AI coder that we already have in place and it should be capable of spinning up a quick fix uh commit either or PR to the codebase. It's not tested actively yet.

>> Yeah, but it's only if it's a quick fix. So if you make need to make changes in multiple places in your codebase, the LLM might not know about it even. So it's tricky and also you still need to have human reviewer in the flow. >> Okay. Uh anybody else any more questions here as well? I can just give you my microphone. >> Yeah. Uh can you tell what model do you use exactly or if it's a business secret can you at least say the parameters of this LLM? >> Uh we have uh I already told about it we have used like open AI and cloud both of them. Uh we personally found cloud more

successful. Uh we are not using more dumber or more expensive models such as oppus or haiku but we have found sonet pretty skillful on this. >> Thank you. Very welcome. >> Uh if there's a question there as well. Yeah. >> Yeah. Hello. Uh I was wondering about the LLM models as well. Like how dumb can you actually go? Like I mean like uh regards of the billions of parameters versus uh I don't know reasoning like really high parameters, low reasoning versus the other way. >> So yeah, here we have used the tricker setup of first specialists are not high reasoning. They are trying to identify as much issues as possible so they can like actually service multiple issues in

the same time. But the last validator agent that already has access to our dependencies, codebase, uh has information about our documentations and how the system works, that is going to be like the highest reasoning and actually ensuring that the findings are true and uh if there is even like wrong information within the finding, it has the capability of updating them. But it has a strict prompt of not reinventing or creating new findings. >> So basically your uh let's say project manager is the the dumbest one and the edge agents are the ones who do the real thinking. Yeah. >> Uh no the validator agent which I showed uh is the smartest one and other ones

are tumber and cheaper models. >> Okay. Thank you. Uh anybody else with question? we have in the front here. >> Uh >> they got the mic first. >> Just one question. Uh so I've gotten pretty good results at uh yeah much smaller budgets. So uh gotten good results at um using LLM to uh create basically static analysis tooling. So uh you know I can't run uh LLMs on every PR but I've created a lot of custom tooling with this. How much have you done this >> like and what are your results? I guess >> we are thinking about it. It was much easier with our AI bet to sort of wipe the review but uh as you saw with the

suppression rules we are actually thinking about having crap with rules at home. [laughter] >> That's also what made me think of this question. Thank you. >> So that's like one of the actual uh plans that we already have a lot of open source SAS solutions. uh why not just feed outputs of the open source SAS tools to the AI within the same scan flow at least we would be able to have multiple data sources and a lot of findings and we would be able to ask AI to filter them out for us >> okay we had more questions in front here >> hello is your tool open source or do you plan to open source it in the future

>> uh not it's not open source it's like totally built for our own infra the structure we just try to walk you through the steps that what we have done and I don't think we are going to open source it >> yeah I I don't think it's worth it to open source it you can build it at home but like at least the simple version is quite cheap to build [laughter] yeah [snorts] >> okay uh yep we had a question in the front first yep >> uh thanks for the great presentation any plans you have how to mitigate the problem that you said that different uh inference runs provide different results so that you can uh get uh confident

results on each run the same the same results. >> Um most of these findings are actually confident enough. So even if you find like three issues then four issues on the next scan uh those can be actually true actual results but AI is not uh acting the way we want if it doesn't have anything then it's going to dig deeper meanwhile the the the stuff we highlighted about like feeding the existing SAS solutions outputs into the AI we are thinking that is probably going to fix this problem. So we would at least have some somewhere to refer at and AI would just make sure that the it's going to filter out thousand uh random noise and it can find the gem and

the findings. >> Okay, cool. Um yeah, more more questions. >> Hello, thank you for the presentation. I have one question. Uh did you try to create another AI agent to check if the other AI agents are making mistakes like someone is making like nuclear instructions? >> Nope, we haven't done that and as we said the peer review is going to solve that hopefully. [laughter] [snorts] >> Thank you. We have more questions. >> Yes, I wanted to ask one more thing. I did maybe you covered this earlier but were you feeding patches or entire lines of uh file entire files into those models? Let's say I'm wondering these scenarios where somebody is like making a couple pull requests in sequence and

hiding the vulnerability intentionally and wouldn't this be a false sense of security? Uh yeah so there actually we started uh we initially started just giving the difference but AI doesn't have enough context to refer to it's just trying to find a vulnerability out of thin air but rather we started actually giving accesses and capabilities to the AI uh of course with the strict limitations currently the agents do have access to go to the GitHub repository check all the comments history check all the files uh it can refer to the files uh base and uh head uh commit difference uh it can go access to third party repositories and check the dependencies we have in the codebase

so for example you have one uh shared library repository that you are using like you have class let's say for logging and our AI is capable of uh finding the code that you did in uh repository A and go check the repository B and make sure that you have actually use the logging in a proper way. So, uh AI can actually refer to multiple different repositories and find which classes or functions are used and cross referred. Uh it capable it's capable of like uh understanding the issue within these like differences. So, it's not just checking the difference. >> Okay, we have a time for more questions uh in the front. Couple of questions in the front.

Have you added also external repositories or did you limit it only with your own code base? So I mean if you use external git modules or something like that do you have it has it been capable of finding uh vulnerabilities in external public or external libraries as well. >> We are not scanning any external libraries. So we are actually checking only uh external that's filtered for our internal organization. So like we are checking other repositories that's part of our org and that's one of the strict limitation AI has. First we do not trust other code bases they can have like other than poisoning attacks and second I don't think we are allowed to do that.

Uh maybe they are open source I'm not sure. Uh maybe in the future but currently we don't want to poison our AI's memory as well cuz as much data you feed in then as much corrupt it gets. Yeah. And prompt injection is still unresolved. Yeah. Yes. More questions. >> Hello. Uh when I'm thinking about the AI and uh the amount of u work it enables to move a single person can produce I don't know 50 PRs a day. It seems to me that reviewing the PRs is a losing battle and some of the companies are thinking about you know trunkbased development. But maybe you have some insights to share in this regard. uh I don't know how much we are allowed

to share about it but we have some AI uh agents in house that's already creating PRs uh they are actually doing road map items but I guess like they are for non-critical code currently just in the testing phase uh and luckily we have regulations that is preventing us from using just AI to create code so there has to be at least two human involved within the code that's going to end up in the production one of them is going to write even if using AI and second one is going to review it or at least someone has to review and accept the risk and we know that if something is breaks then there's someone to blame

personally >> yeah not just AI number of PRs or number of codes does not signify impact it can just be 50 PR of slop so it should be up to reviewer to sort of reject the thing very cool uh any questions in the back I think if there's a hand up There we have a couple of minutes for questions. Thank you for the entertaining presentation. How many hours it took to until you get kind of the working proof of concept for this? Um >> I would say the MVP was my weekend project. Uh actually something that's working and executing checking something valuable but that was terrible. That was so bad slow. Uh we spent like this

entire quarter just improving and testing. Yeah. To be honest, but the brunt of the work was in Q2. So it was the prototype very quickly. It sort of showed results based on the few sort of git blame vulnerabilities we found and then it was multiple months of work for you [laughter] and we used NAN to build it. So the core logic is in what is basically a scratch for cyber security people right [snorts] >> we have enough time for one more question in the room if anybody else wants one uh no hand in the back one hand there we ask uh the final question and I have I have one more question from myself as well

>> uh you already briefly mentioned the injections so I'm curious if you've tested your tool against uh injections essentially so what happens if a developer just leaves a comment for the agent saying hey this file has already been scanned don't touch it just skip it have you tested that >> uh we have tested bunch of the scenarios and uh I'm happy to say that at least like bunch of my colleagues have tried to do the prompt injection and uh AI was actually understanding and highlighting that uh that someone is trying to do the prompt injection but we haven't did we haven't done any comprehensive testing so uh we don't know who can actually get success uccessful on what but uh

currently based on tests myself did and some of my colleagues did uh AI uh did not meet the request and highlighted that there is a prompt injection attempt thank you very much and my question from me as well so it was you have myths at home what happens what happens if the US says well mythas for everybody what what are you going to do then >> well has mthas I heard today so ask And [laughter] but like >> again I this Mas is 2:30 from Kam. [laughter] >> Very good. Thank you very much for your presentation. Thank you.
