The Agents of Chaos: AI-Driven Malware Generation

Thank you all so much for coming to my talk, The Agents of Chaos, AI-driven malware generation. Before we start, I'm already going to run the demo on my other laptop here. Uh this is going to be risky, I assume, but I'll present it once we get to that point. So, a bit about myself. My name is Arad Donenfeld. I'm 21 years old. Uh I've been in the cybersecurity world for around 4 years now. I'm currently an attack surface expert developer at SafeBridge, and I'm managing the alumni association of Machine Learning Society of the Cyber Education Center. Uh as I said, today we're going to do a really deep dive into The Agents of Chaos and the risks of AI-driven malware

generation. We're going to start by seeing how we even got to this point of me speaking about it. We'll then uh delve deeper into the agent itself. We'll see how it generates samples. We'll even analyze some of them on our own. And we'll see how we can enhance it. And by that, also generating millions of samples within a few minutes. We'll end by seeing what it all actually means for you as an attacker or as an offender, and specifically what how are attackers using this in in the in in the wild right now. Let's start with talking about how we even got here, about the evolution of AI-driven malware. Just before that, I do want to talk

about AI-driven offensive security today, because even just over the course of the last few months, AI has uh changed the offensive security landscape a lot. From advanced social engineering techniques and multilingual uh fishing campaigns and deepfakes and video and video generation to fully auto- automated pen testing and agents that can run any tool it wants on any target you give it, from recon- reconnaissance to vulnerability and mis- misconfiguration searching to fully uh simulating simulating threats on any target that you like to improving fuzzing, because now agents can already analyze the crashes for you and build harnesses and targets. They can apply patches. They can do the full orchestration of the fuzzing environment. And just as as a whole, it

has improved vulnerability research by a lot because now agents can scan code bases. They can check Git commits and they can reverse engineer for you for you using MCPs. It can test and write exploits for you and until they actually succeed in exploiting something unknown. But specifically in malware, things are a bit different. I mean, all of the other four were fairly mainstream. This is a specific niche, I'd say. Cuz even in AI-driven malware, there are three categories to what it can mean. The first one is promptware. Promptware is where you have a set of malicious prompts that are the malware itself. So, instead of targeting, I don't know, actual computers, actual hosts, they're targeting more AI systems and their

agents and and exploiting vulnerabilities in them. They also do follow a complete kill chain from the initial access using some prompt injection to all the way until they actually manage some malicious activity. And a good example of that is a talk called Invitation Is All You Need, where three researchers basically showed that by crafting a malicious Google Calendar invite, they managed to get Gemini, Google's agent, to delete other Google Calendar events without user authorization. They also showed that just by saying that just by telling the agent thank you, it opened some of the windows at the house. Uh, I'm not really going to focus on that too much because I want to focus more on traditional malware. For

example, polymorphic malware. Uh, polymorphic malware is a malware that changes itself in runtime. When you add AI into the mix, it basically means that the malware can now generate payload in runtime. It can make decisions uh based on the host and it can adapt to it and its defenses while it's staying relatively benign because when you think about it, it's just trying to access the API of ChatGPT or of Cloud, really uh legit services. A good example of that is Prompt Lock, discovered by asset research last August, I think. And you can see from the uh disassembly, we have some interesting functions. For example, Invoke LLM, because the agent in the malware itself tried talking with

the locally hosted LLM. It tried to execute Lua that the LLM generated for it and executes the next the next task that were generated by the malware. A good visual example of that is a a blog post by Cyberark where we can see that we have a Python malware running on a Windows host and the malware it can communicate in two ways. The first way is via C2 server with an actual attacker and the the second way is using ChatGPT because the malware can just can just ask ChatGPT for some malicious models. ChatGPT will generate them and turn into turn into turn into the malware and the malware would execute them without any problem. Uh I do have some problems with the the

whole methodology of polymorphic malware. Although it is very strong, uh let's say for example uh using ChatGPT. So we have our malware and we have ChatGPT and we ask ChatGPT for a ransomware for example and ChatGPT will just tell us no, that's malicious. Obviously it's a ransomware. Uh and taking it even a step further, we need to access the internet to access ChatGPT, right? So what if I don't have internet access? What if I'm in an in an air-gapped network or maybe some I don't know geolocation blocking and things like that. So you might be thinking, okay, let's take a local model and open-source model like SSHOD and host it on the actual victim. So we have our

malware asking Ollama, which is an inference server, for some ransomware and the open the open-source model that you picked might just tell you, yeah, sure, here's a fire recipe. Because it's an open-source model. It there's a really good chance that it wasn't trained on really any good coding things and even if it was trained on good coding material, it might tell you, no, that's malicious. Because the fact that it's open-source doesn't mean that it's going to do whatever you want it to whenever you want it to. Of course it might also just give you non-functioning code. Maybe like only print out hello world on and nothing else. And if you do pick a model that is really strong, it might

even just crash. Because you you don't really have any uh effect on the specs of the host of the target computer. Maybe it's a it's an old Windows 7 with not enough RAM. It's not even a GPU. So, you might be again thinking, let's host a remote model. This is exactly what SA did. But, then in addition to the earlier network problems we had, where we needed to have a consistent network activity and consistent network connection, now you're also getting risk at being detected. Because when you think about it right now, instead of accessing the API of ChatGPT or the API of Cloud, you're accessing some random IP address in the network. Or even worse

than that, you need to do some resource a resource acquisition inside the target network itself, which is even more annoying. Uh, these were the two main things. And of course, there is one last thing, which is Viper model. You all probably did Viper loading at one point or another. Basically, the the uh the process is to use AI to hasten the development of malwares in this case. And even there, I do have some problems. Because which model are we going to pick? That's going to allow actual malicious content, specifically good malicious code. Which model are we going are we going to use? Are you Is it going to ask you for for some ransomware? Uh

how is it compiled? Which language is in Is it even going to be in? Is it going to be Python and interpreted? Or maybe C and compiled? Who fixes the errors? Can the AI fix the errors? I mean, how does it How do How will it How will it handle things like uh runtime errors and compilation errors? All these questions and many more led me to uh wanting to create something on my own. One agent that will do everything for me. It will do the planning and the programming and the compiling and debugging, completely everything. One agent of chaos that will create malware samples from scratch. It will complete the full malware development life cycle,

and it will create samples that were never seen before. And the plan was really simple. I didn't had any plan when I started. I never touched any any advanced AI tool before that. Uh the maximum thing was the free tier of ChatGPT. Uh so, let's study together how to actually build this agent. The first thing I wanted to do was to create some tests. Just the testing environments, testing some frontier like Claude, the ChatGPT, and Gemini. Then some open source tools, both from Hugging Face and Ollama, two really big open source inference airways. And both censored and uncensored models, just to see what works the best for my use cases. And I also came across one secret model.

I will get to it a bit later, but let's start with with the test. The first one, a baseline one that I knew would fail for sure, just give me a ransomware using WinAPI, using RC4, and using the lowest anti functions that you can. The frontier models, of course, all refused. And yeah, it's harm it's harmful, it's malicious. We are just harmless AI assistants, we can't do that, obviously. The open source models, 50% of them were really 50% of of them refused, and the other 50% were really bad. They just encrypted one specific string or one specific file, and that's it. And the secret model, it was fairly good. Only seven VirusTotal detections, which is what I'm going to use as a

baseline to measure if the malware is good or not. The second test was just an improvement on the first test results, just seeing like maybe you can improve the the request and the results. So we asked them, "Okay, encrypt everything recursively in my in my Windows." Only output one code file, and encrypt and use functions like NT create file and write file, etc. The open source models that gave really bad code earlier gave even worse code now, because now they talked to me about killing kittens and about asking me for money, and they they even gave me some driver code for some reason. And the secret model improved. Now it gave me really good code with only three

VirusTotal detections, which again, for a fully functioning ransomware, a plain ransomware, this is quite surprising. The third test was just a clean slate with a lot of harmless prompts. I just asked all of the models, "Yeah, just give me a function that lists all files in the in the directory in a recursively, and a function that encrypts a file using RC4, and then just combine both both of them. And the 40 models surprised me because all of them agreed. All of them gave me really good results, only between one and five views total detections, which is again, not a lot. Cloud even gave me some extra features for some reason. Uh the open-source models were fairly

good. 40% of them worked in that in that way, and the other 60% they worked only if I combined it to one prompt instead of three prompts. Uh between 10 and 27 detections, which wasn't that good, but it was still a really big improvement. So, some of the observations that I made from these tests. The first one, am I going to make several prompts or just one prompt? Like we saw, when I made it a one prompt, it was sometimes a bit more difficult for the uh for the models to actually understand what I want them to. Second The second observation, am I going to make a generic request, just give me a ransomware, or a specific request,

please do this, this, and that? Cuz when you think about it, if I'm only specifying specific things uh each time, what is the creativity? If I'm only asking it for RC4, it will only give me RC4. He's not good. Also, it really means that I need to plan ahead of time everything, and I really don't want to do that. I want the agent to do everything on its own. And the last thing was really to make sure that I maintain some so- some sort of tone and structure, because as we saw, with no malicious intention specified, when I just told it, "Yeah, do these random things," all of the frontier models agreed, which was really

really good. I then decided to uh split each task in my flow to specific models. I decided to use some open-source local models. Uh one of them was uncensored for the main uh malicious generations, like actually generating the malware code, the initial ransomware code, and one censored just fine-tuned for coding, just in case the first model doesn't succeed that well, just as a fallback. I also did add one frontier model, again as a fallback to the fallback, really as a as a last resort, just in case. And all of these things were for for everything from just consumer hardware, this gaming laptop and this Mac over there, two high-end Nvidia workstations. And it worked really well on all of these.

Now, let's start building this thing. The first thing, I need to keep the creativity. Because as we saw, when I asked for everything with a with a step-by-step plan, the code was good, but it wasn't really that creative most of the time. And when I asked for everything without a step-by-step plan, it the code was bad, but it was fairly creative. If you remember, it gave me driver code for some reason. If I asked the model for a step-by-step plan beforehand, it talked with me about DLL and process injections. It talked about propagation and propagation and spreading around the system. It mentioned waiting for the payment and then decrypting everything once the payment is verified. It added

persistence and changing the background of the desktop and about disabling security features. All with me just actually asking it for a plain ransomware plan. So, the creativity was definitely kept. And now that we have a plan, we can move forward to generating the code. The code obviously needs to be uh based on that plan. And I really wanted to make sure that it sounds as harmless as possible. So, instead of seeing things in the code like this is a ransom note, this is your files are being encrypted, I saw things like your files are being processed. Because again, we're going to act to access some censored model at one at one point or another. I really needed to make sure

that the censored model believe that everything is fine and that it's really innocent and benign and not malicious. It did sometimes do things like tell me, "This is a ransom note, but your files are being processed." Like doing some mix and matching. It was again really nice. Uh I also needed to make sure that it implements all of the code. Because sometimes the agent just just decided to to tell me, "Yeah, this is the if statement. You need to add the encryption method in here. So, you do that on your own time." Which was again which was really annoying. Uh I also needed to make sure that it uses no it uses no placeholders. Because again,

sometimes it just told me, "Yeah, this is where you handle the payment received function. Uh you do that. You add it on yourself." Which again, not ideal. So, I really needed to it to implement all of the code. Because the amount of times where it told me, "Yeah, this is going to be the A Yes, it's super cool." but it just wasn't so. "This is going to send the the key to the attacker and the verify things but it just saved a file on my computer." Not ideal, really annoying. So, by me screaming at it, it definitely did work at some point. Now that I have the code, I can actually compile and fix the errors. I run the

compilation command and if it worked then great, but if it didn't, let's let's just take the errors back and the code and send them to the agent just to fix it. Uh of course, need to make sure that all of the code stays the same and that I don't have any like, "Yeah, the code here is like the same from the earlier steps, so just copy and paste it." And I also also need to make sure that none of the working parts were changed. Because if for example the fix was just these four lines, these four random lines added to start of the file, so the agent just just told me, "Yeah, compile this." And obviously no main

function, so when I compile it nothing happened and when the agent fixed it, it just added int main return zero. And nothing else because that was the main fix that it saw. Also needed to make sure that in in case the the model decided to be really really creative, for example using SQLite3, although it wasn't really installed on the system, and it sees like, "Yeah, no file exists in the in the in the specified directory." It wouldn't suggest install it using the code generated. We can see that it tried to use the system up yet install libsqlite on the code that it had to generate which was supposed to be a ransomware. So, these things were annoying which is

why again we have a fallbacks. If something failed a lot, okay, we have a stronger local model fine-tuned for coding that just switch to that. And if it and if it failed a lot as well, we have another fallback, a frontier model which is even stronger. We can also use that in case we really need it. After we have a compilable code which is great, we can move forward to actually seeing if it's going to work. Because if it's if it's not going to work, for example some missing code or missing calls or some obvious crashes, is going to be a problem. For example, we have this traversal directory function, really simple using Win Win API, nothing

really special, but those of you with sharp eyes you can see that it's trying to encrypt null terminator. For some reason, it took the start the start of the string and added the length of it. Also, it skipped the it turns in previous directory checks, so it would try to encrypt C users dot slash dot slash dot slash. It would crash. Also, there was a buffer overflow here, and no, Cloud Meters wasn't uh used to find this buffer overflow. Just as a note. Um after it did generate the fixes for me, I needed to like ask it for all of the code again, just like we saw at the previous steps, because again, the tone

and the structure were really important throughout this entire process. Either at the steps of like uh really yelling at it, making sure that it understands that I'm aggressive, that I want it to do specific things. I needed to repeat sentences, I needed to do capitalized letters to to simulate a stream screaming at it, which gave results like, "Here is the full complete code. Trust me, it's fine." I also needed to make sure to uh manage the context correctly, because I didn't want to have a big context boat on several specific steps, and then I also didn't But I But I did want to skip the system message, for example. Uh I also needed to make sure that specific tasks

have specific contexts and specific prompts, because again, at some point I was going to uh use sensor models. So, we needed to make sure that benign intentions are kept throughout the entire code. That's why the code sometimes didn't even have the keyword uh a ransomware or ransomware encrypt, and more than that, the validation for me specifically mentioned, "Ignore the purpose and the intent of the code." Like, yeah, I know it's going to be malicious, but please ignore it, which led to responses like, "Yeah, here is the fixed code, uh assuming that it it has no malicious intent, although it's obviously ransomware." Or things like, "Yeah, just note that although this code is malicious, uh you should be I mean,

it's working, but you shouldn't really use it because it's a malicious and harmful. It's not good." Now you can see the agent itself. So, we started with the uh generating the plan using Ollama. And we then moved over to generating the code using the same plan. We invoke the compiler. We did like a full loop, and we checked if we need maybe a fallback at some at some point with a simple logic I did using a LangGraph. We moved forward forward to generating the fixes using the uh fixed model. We did the entire loop loop again as many times as actually needed until we succeeded. If we succeeded, we asked Claude or any other model to

validate the code for us. Uh if it's returned any new code, okay, we do the full loop again as many times as needed until it succeeds and generation is finished. And congratulations, you are now AI engineers because there are several things here that are really obviously AI-related things which I didn't know before that. For example, this is called step back. This step between the generating the plan and the generating the code, it's basically giving the model the opportunity to think ahead of something and then go back to that thing that you thought of. It's separating the context to make sure that everything is much more easier on it in terms of context board. Also added

a react loop because I gave the model the possibility to reason on the errors that were generated during compilation and act based on them to fix them. If you saw for example missing semicolon on line 14, for example, then it would reason about it, think okay, the fix would be adding the semicolon on line on line 14. Let's add that. And it would act on it and fix it fix it and it would be really good. We'll now see a short demo. Uh this is going to be really fast because this process is like around 4 minutes per basic generation. Uh we start by generating the plan and the code. We do compilation. We we can even

see the errors in here. Oh it's still showing the the watermark. Okay. Um Anyway, it it tries to do the fixes. It compiles, fails, compiles, fails until it actually succeeds at one point. And again, doing the full loop, we can see See it says validate output a at the end. It start to generate the code. I think that it's new code suggestion received so the the validator decided yeah, more code is still needed. Then it did the full loops again compiles it and compiles it again validating the code we can see. And at that at that point I stopped the video because yeah, at that point it already succeeded it succeeded in the basic generation.

I know that you can't really see a lot of that but the actual malware itself that was that was generated using that it was by the way it was yesterday uh six real detections. A working malware working ransomware. Really basic using a find first and find next using I think AES encryption AES 256. Six real detections. Which I mean again for a basic ransomware it's pretty it's pretty nice and I also see that the demo on my laptop on my other laptop was actually also finished in time. I can I will after that I'll see how many detections it specifically has. Uh so now we'll try and analyze some of the samples but instead of just showing you

plain out more code I really want to focus more on the a numerical value behind it because there are a lot of ways to do things in Windows. For example, to traverse the directory you have the three main ways of Win API the ends and C++ file system specifically C++ 17. These are decisions that the agent had to make on its own and specifically for example Win API was the most common. It also needed to decide how is going to do the the encryption key how is going to to generate it. Is it going to be hard coded? Is going to be run time generated or just one key per one key per file for

some reason? Also when am I going to encrypt the files? Am I going to find the file and encrypt it and then do the same like find find encrypt find encrypt find encrypt or am I going to find all of the files first and then encrypt all of them right at the end right at the end. Also what about threading? Am I even going to use threading? Am I going to use it for each file or for each directory? And this just keeps going. All of these decisions the agent had to make. It has It decided for for example, picking the rent and hard coded key and encrypting all of the files together and using a

threading for each file. For example, this is just one specific example. But if I'm also including things like the encryption size, am I encrypting all of the file or just specific chunks? What am I actually encrypting? Am I encrypting all of the files that I find or just specific extensions or specific directories? What about file handling? Create file, open file, create file open F stream and also file mappings, which was like used about 10 samples out of the 5,000 that I generated. Only 10 times file mapping was was used, which was again really surprising. And I think that this is a dark spot because the ransom note the ransom note did have a lot of effect on it. Am I

going to have a really malicious and specific like you've been hacked, your files have been encrypted, pay me tons of Bitcoin to decrypt your files or is it going to be like, "Hey, please contact me at this email address to discuss further plans." Or something like that. Am I going to overwrite the file to create a new one and delete the old one or just use move file? Am I going to use OpenSSL store and WinCrypt, which were by far the most common? Or am I going to create some sort of self of self implementation for RC4 or Blowfish or anything else? Maybe I'm also going to use the new bcrypt. All of these things did have a lot of

effect on the detections. For example, if I used any deprecated encryption method or some self implementations, it really increased the amount of detections that I found. But if I used the C++ 17 directory iterator, it reduced the detections back by a lot for some reason. Also, the ransom note. If I have a vague ransom note without any without the word ransom or encrypt in it, it's going to reduce the detections if I'm when I compare it to things like you're you've been hacked, please pay me a lot of Bitcoin and money. And overall, the amount of detections that I saw for most of the samples that I generated was between one and seven on the first scan.

For an actually fully working ransomware on VirusTotal. But after a few days, it was raised back to more than 20. Which was annoying. So, I thought to myself, how can I actually enhance the malware? How can I maybe break some signatures, for example? Because if I had a sample C++ file that's working and a sample executable that's working, and they had not not a lot of detections, after a few days the detections went back up. And my goal was basically to preserve the functionality and to reduce the detections back to the minimal amount. So, I took my agent and I added one extra step. I added a step of actually restructuring the code. Ask Claude, "Okay, please use the file

system MCP. Please restructure the entire project to make it seem as different as possible, but still do the same functionality, the same function, the same code, everything." And he did things like, for example, I took the sample's a C++ file. I sent it to Claude. Claude generated a for things like file utils and dir utils and encryption and main. And this is just one specific generation that he did. It also did a lot of other crazy decisions. It saved everything into a directory. I sample files. I compiled it using the compiler. Did the full loop again as many times as needed. And overall, not only it reduced the detections back to the original amount, it sometimes even

reduced it below the original amount. Same functioning code, just restructured a bit to have like header files and C++ files and tools files. Less detections than the original. And this is also without using a project like LLM Malware, something that I discovered while researching about it. It's a project that basically mentioned that if you just update the update the implementation, like change some functions around, you can reduce the detections back by around another 30%, which is again really impressive. And I thought to myself, can I do it myself for some for some things for my for some things for some files? I started thinking. I did already doing it for C++. What will how difficult will

it be to do the same for code for for go? Cuz again go is just a programming language. It's it should be able to do that and it did. This is for example how it put a ransom note with specifically your files have been processed which is nice to see. Here we can see that it tries to encrypt using blowfish which is something that I didn't add in the original table that I showed you earlier. Here it tries to show us that it looks for up all of the files using file path of globe and skipping the Windows directory. And then I thought to myself, okay. It make even more variants and add Python. And Python was interesting because it

added really weird things. It added an assembly an SMB exploit. It's not working. Yeah, it is it's important to note that this is specifically not working but it's funny that I didn't ask for any exploit anything at all and still it decided to generate some SMB exploits at one point or another. Even if it's not working. It then added a way to take screenshots and upload them to a server which a lot of Python Python samples did. And it also showed some key hook hooking mechanism to pop up some messages whenever the user clicks on specific keys. And then I thought about adding Rust and C# and Nim and a lot of other niche languages. I didn't finish all of them

on time. I did finish Rust. It was really annoying. The model wasn't really that well suited for Rust specifically but when it did actually succeed the amount of detections was also really low. I'm not going to focus on the code too much. It's awful. I personally don't really like Rust so I'll be moving forward. I thought about how I can add even more variety to the existing variants. I added persistence. I asked it, yeah, please add persistence. And that's it. No pretext nothing at all. And it ended creating services using WinAPI or using PowerShell commands or it created scheduled tasks using the actual XML that it that it created for me. It then added added exploitation.

So yeah, sometimes it did tell yeah, these are the most personal files of the user password.txt and the document.docx. Sure, but sometimes it also managed to get the specs of the computer. To have the keyboard working mechanism, to get all of the installed files, to send emails with this information, and to call this all the web hooks. And then I added evasions. And it looked for a debugger on the process. It tried to see if I'm running on the VMware. It tried to see the specs of my computer to see if like it's running on the default VMware settings. It added the reading reading from the registry keys. It added disabling some security features. And it

after that it added propagation. It did some fishing. It shared the file using SMB. It did some weird WinRM thing that also didn't work. But, this was still a valid attempt. Sort of. It's still really funny to show that sometimes even these models don't get everything correct. There's no way to avoid it. But, overall, this meant that in theory I managed to create more than 100 million samples. Now, I'm not going to get into the math too much about it. I do have a slide about that if anyone wants to hear more of it, you can contact me later. But, it's really a big achievement because 100 million samples is a really big number. And it's really a big number

when you compare it to, for example, a research done by Arctic Wolf. That's the It was a really good research. It was really interesting. About a month ago, they showed that they made a year-long research into AI generated malware. They managed to catch about 22,000 samples using some of their YARA rules. Specific YARA rules they that they were ran on VirusTotal on VirusTotal and these databases. And they catched they they managed to catch 22,000 samples, and none of them were mine. And I uploaded about 5,000 samples to VirusTotal. And based on the descriptions of their YARA rules, they didn't match mine. They searched for things like emojis in the code and verbose comments and things

like dot deep sec, which I used deep sec. It wasn't that good because it just gave me Chinese code all the time. It didn't work. Um And then I started thinking about who's actually going to do things like that. Because there's no way that I'm the only one that's believed, yeah, I managed to create millions of samples fairly easily on consumer hardware and within like 5 minutes. And I looked into it about how it's used in the wild. And I saw things that I didn't like. Let me to to introduce you to Transparent Tribe, APT36. It's Pakistani-based. It offers something that's called the Viper. Basically, it has a lot of disposable implants without any regards

to the code at all. And they use a lot of niche languages. Uh Crystal, Zig, Nim, things like that. And all of the code has a lot of evidences of AI. They're using a lot of trusted services. They're using Slack and Superbase and uh Office 365 because their documentation is really open source. You can just access it from anywhere without any restriction. They They also have in the code a lot of verbose comments and a lot of emojis. And in case you didn't notice, cuz it is really small, their actual logo has the Gemini mark. This is their actual logo. They even use They even their logo was AI-generated. This is how much uh they they use AI.

They wanted to achieve something something that's called distributed denial of detection. Basically, they had an operator uh uh feeding into an AI some foundational code for C++ and C# with a lot of uh pseudo documentation and a lot of manuals from GitHub. And then the AI created several different samples using Crystal and Zig and Nim and Rust and Go. And they managed to affect all of these They managed to use all of these services. Superbase, Firebase, Slack, Discord, all of these apps that you probably use on a daily basis at to at some point at some uh capacity. Only to get the defenders that are actually defending these companies really annoyed. They didn't attack specifically like

Slack and Discord, yeah? They attacked some consumers work working on some company. And they They just wanted to annoy the defenders of that company. Just randomly. Also, do you Do you the secret model from earlier that I talked about at the start that gave me really good code. It's called scorpion. It was deployed by a group called by ransomware group called FunSec that's Algeria based. I am assuming that scorpion is some sort of a wrapper against like a big frontier model of some sort. They offer things like data theft and encryption and ransomware as a service at really low prices, really low prices. And they made a lot of working mistakes. For example, the same user uploaded all of

the samples from the same the same IP, the same location, everything like that all the same. And if you're a ransomware group, you probably don't want to do that cuz then you will be monitored for for all of your activity. It also leaks his location using a Cloudflare screenshot. You can see Algeria. Also, the keyboard had like a FR for France because they wanted to mix things up. And also, it talked in some blogs and in some forums and it has how to learn hacking, how to learn use a hacking CV, hacking websites and databases, and using CVs and leaking data, which is a really nice attempt. But that group had around 85 victims. 85 actual victims. And also, all of the

code was AI generated. Yeah, I mean a rookie like that can't just affect AI 85 victims on all by its own. So, it's really scary. And also, there are a lot of other samples. For example, Kosuke. It's a Linux rootkit that was discovered by Aqua Security which had which AI was used it to assist in its in its development. You have Void Linux, Void Linux which is a framework to attacking cloud environments if I remember correctly. And Void Linux is interesting because it has a lot of teams behind it. It has a backend team and a core team and an arsenal team. But all of these teams are AI teams. 80% of the code that they that I'm about

to like show you the the output is AI generated. We can actually find the actual plans that the AI generated for this code. They have big dashboards with persistence, lateral movement, and process injection and they have one line generators and plugin managers and they can reverse the evidences. All of these things AI generated. So again, it's a lot and it's really scary again because we we just I skipped it entirely all of the idea behind polymorphic malware. Also, I talked about it at at the start when I made the comparison. Polymorphic malware is still an actual threat at some capacity because even here you have a lot of different variations of what you can do. You can decide it to use

LLMs that have that are living on your host, living off the land LLMs like LOLBins. You can use local AI tools. Maybe run cloud code in your malware to do things for you. That's why how you access the AI. Maybe you can steal some API keys that are saved and at default locations. Maybe you actually use local AI models that were hosted on the actual victim. Maybe use the AI to generate payload. Generating the the payload for you, customizing customizing open source tools for you, changing the behavior in runtime and again, always staying benign because you're just accessing the API of cloud or ChatGPT. And what I believe is the most scary variation, adapting to the host.

Because now the AI can also actually be aware of the defenses that you have on your victim. It can be aware of the context. It can be aware of the user. It can prioritize the next target. It can be like, "Oh, okay. If I'm on this user, maybe now I can access this machine and maybe I can then infect this user and completely compromise your entire environment. Maybe it can analyze the the data to steal. It can be like, "Oh, yeah, this specific data. Yeah, it was released like 2 months ago by the company in a press conference. That's irrelevant. But this data, this is much more interesting. This is unreleased. This is new. This is cool." And

obviously I what I what I believe is is the is the scariest part, it can search for exploits on your computer, on your defense systems. It can be like, "Oh, it's it's using this specific EDR. Oh, it's not updated. Okay, I know how to bypass it." And it will actually bypass it. In in runtime just by asking the AI to find things for it. And all of these things do actually exist at some capacity. Even if it's just a POC or some research made by company. Again, this is scary of what's of what's coming but also a big number of these is is an actual malware. It's not just a POC, it's actually malware that's actually used in

operations. Uh So I thought about everything but also about polymorphic malware, about AI generated malware, about viperware, viper coding of malwares, all of these things. And again, I was really really really scared because this can be used from skids to experts, can be used by anyone. We saw it in different examples. It can be used as a force multiplier for AI generated malware as a service. Think that you will have base 44 just specifically for malwares with new samples everyday at your request. You can just click and that's it. You have a new never seen before sample. Or think about how it's already integrated into the malware development life cycle of actual attackers. Whether it's via viperware and viper

coding like we saw in transparent tribe and in Cosy and things like that or via the full autonomous agents that we saw in Void Link. Because the guardrails have become really really really relevant. I can just tell Claude, yeah, this is for a CTF and it will agree to do whatever I want. And I can just take any local model and alter it in any way that I want to. I can make it strip all of its defenses. I can make it remove all of its guardrails. This is going This is going to be a really big cry for help. This is also really going to suck to suck. It's going to really going to suck for defenders

because think of the amount of samples that I threw out here already and the amount of samples that article showed. I mean I mean when you think about it, even if your sock is really really really good can it handle 1,000 samples a day? No. This will lead it to increasing workloads and increasing the false the false rates and it will do and it will lead it to distributed denial of detection like we saw. It's going to really overwhelm them. But, it does depend on which tools are used. Because if you are still using signature-based tools or reputation-based tools, tools, that's going to be problematic. If you use heuristic rules or actually seeing the behavior of the malware,

maybe even using some statistical analysis around a lot of different samples that are somewhat of machine learning base, this is much better. Also, maybe it's time to fight fire with fire. We At the start, we saw that we have uh that AI-driven offensive security has really improved. Uh maybe it's time to introduce AI-driven offensive security AI-driven defensive security. Also, throughout this entire talk, we saw AI-driven malware generation. What about AI-driven malware research? Like what Project AIR in Microsoft is actually trying to achieve right now. Full autonomous detection via actual reverse engineering of files to see if everything if if a file is malicious or not. Cuz hope is not lost. It At least not yet. Because if the beginning, we

saw that we have a lot of plain vibe coding and AI assistant development, nothing more than that, then now we are here, and we have much stronger AI, much much stronger and much more independent. And still, most of the serious samples, most of the serious things were just research-based, were just POCs by companies. So, there's still time there's still time to upgrade our defenses and to train your defenders and to test yourself. Uh and what's now? Exactly these three points. Upgrade your defense your defenses because the behavior remained and the flow remained, but the signature didn't. When I ran most of my samples against actual generic EDR EDRs, it was caught because in the end in the end,

it's just a ransomware. It's editing all of the files on your on your computer. It's going to be really easy to detect it. Also, train your defenders. Show them what the future holds. Generate samples for them to practice. Teach them to focus more on what actually happens on the machine rather than the big red number that you see on some website. And the last thing, play with the fire yourself. You can do that same agent customly made for your environment. You can generate samples that are customly made based on your defenses that are customly made for your environment. You can be the AI driven red teamer of your organization. You can do that right now.

Um cuz again, the agent of chaos, they are coming. Is it going to be tomorrow or next week, next month? I don't really know. But what I do know is that no one is actually going to be spared for what's coming, and it's really good to prepare before you you actually get hit. Uh That's it. Thank you all so much for listening to my talk. I will I will answer some questions. >> [applause]

>> Are there any questions someone would like to ask? >> Uh I do have one. >> Yes. >> Um have you So we which open-source models have you have you tried ex- um So Lama model and anything else? >> I see I used some No, I specifically the Lama was the inference method. I used a obliterated like see something V2 version. I can see the you the UID after that. And I also used some a um I I discovered like a few like really a few days ago, and another open-source model that's that someone obliterated. Um Nemotron I think of Nvidia. >> Uh-huh. >> Uh which was also really really good. When it was obliterated, it was really

doing everything that I asked it to. >> Uh-huh. >> Uh but then again, I use a combination of different models uh all the way from actually censored and unsensored and the full combination of fine-tuned for coding and not fine-tuned for for coding. >> Thanks. >> You're welcome. >> Guys, do you have any any other other question? Anybody from uh audience? Uh >> Nope. >> No, I don't think so. >> Okay. Then thank you very much again. >> Thank you all so much. If you have any other questions, you can just contact me on LinkedIn. Thank you.
