If AI is pretty much stealing everything off the internet, wasn’t bad enough. You got to hear this. We’re going to talk about gen AI prompting, going too far and stealing more information than you would like. And cyber attackers are hiding malware campaigns inside Google Ads. Yeah, Google Ads, the thing no one really wants, but is everywhere.
Today, we are facing an unprecedented array of data breaches, hacking attempts, and surges in digital crime. Why is there such a widespread amount, and how little is noticed in our everyday lives? Malware, dark sites, brute forcing, zero day script kiddies, and nation state hackers are all on the rise. Learn more about the threats we face and gain a bit more knowledge than yesterday.
Hey everyone, another episode of Exploit Brokers is coming to you now. Hey guys, this is your host Cipherceval. Thank you for tuning in for another episode. If you could please do me a favor because it helps the channel grow and I’d appreciate it immensely. If you could hit that like, subscribe, and bell notification icon if you’re on YouTube.
And if you’re on a podcast platform like Spotify or Apple Podcasts, if you could please hit follow, subscribe. And give us a five star review. If you think we deserve it with that said, let’s jump into the articles. So I have two articles here from dark reading. We’re going to touch on the first one, which is employees enter sensitive data into gen AI prompts far too often.
The propensity for users to enter customer data, source code, employee benefits, information, financial data, and more into chat, GPT, co pilot, and others is racking up real risk for enterprises. So to give a bit of context before we kind of dive in here, the way that a lot of AI companies allegedly get their data is that they will scrape the internet.
They will use bots and other kind of resources, right? There might be some data sets that they download, but a lot of them are pretty much doing what’s known as web scraping. Which is when you get a bot or a computer program to go and download websites, videos, text, and whatever resources are on the internet that you would normally access via a web browser.
And this is important because if you think about the way AIs work to give you a very simplified, oversimplified explanation, AIs are just very large approximate equations that combine stuff like calculus, statistics, and a few other fancy stuff, um, into essentially B. E. A really, really sophisticated equation, and then when you ask a question, or when you input some piece of data, it tries to find the closest approximation to that answer.
That’s oversimplifying, but that’s kind of AI summed up. So, what happens is, AI needs to keep learning, needs to keep training, otherwise you kind of You hit a wall, right? It won’t go past what you’ve already trained it because it’s not good at creating new stuff, only finding correlations and stuff that it’s fed.
So a lot of AI companies have gotten existing user data and fed it in. There’s a type of AI that’s known as a reinforcement network, uh, reinforcement learning to be, to be kind of more precise. And reinforcement learning essentially lets you continuously feed, uh, kind of like a feedback into the model.
So that way it understands more and more information. Now there’s also the idea that if you have a bunch more data, you can load up a checkpoint and you can just keep the training going. There’s that kind of mechanism as well. There’s, I mean, honestly, when it comes to AI, there’s like a multitude of things.
I’ve only begun to scratch the surface, but it’s pretty cool and kind of insane. But the reason I bring this up is affordable at the data that isn’t on the open internet, stuff like your health insurance or your medical claims. Or your stuff about you. A lot of stuff about you may not be on the internet.
Forget about your Facebook post, forget about your Instagram post. What about the stuff that your doctors and that all these companies hold proprietary about you? Well, that’s kind of, that’s kind of now under fire. Let’s jump into the article and I’ll kind of expand as we go a wide spectrum of data is being shared by employees through generative AI Gen AI tools researchers have found legitimizing many organizations hesitancy to fully adopt AI practices Which, yeah, you have a lot of companies that are hesitant on adopting chat, GPT policies, or, you know, just adopting the tool set because you’re essentially giving data over to all these AI providers.
Now there is a certain models that you can load up and, you know, if you have the resources, you know, think cloud or a good enough, uh, GPU, like a 80, something that can load up a decent size model, then you can technically have it closed right behind closed doors. But a lot of these companies will not set that kind of infrastructure up.
So you have employees using just the web based version of chat, GPT and the web, the web based version of chat, GPT. Under its usage says that they can take your data and train and you’re kind of wondering why I’m saying that well That’s kind of what we’re gonna get to every time a user enters data into a prompt for chat GPT or a similar tool The information is ingested into the services LLM data set as source material used to train the next generation of the algorithm The concern is that the information could be retrieved at a later date via a savvy prompts a vulnerability or a hack if Proper data security isn’t in place for the service You That’s according to researchers at Harmanuk Security, who analyzed thousands of prompts submitted by users into Gen AI platforms such as Microsoft, Copilot, OpenAI, ChatGPT, Google Gemini, Anthropic Clause, and Perplexity.
Let’s kind of give a bit more context here. So the savvy prompts is pretty much an attack that manipulates the AI into dumping some of its training data or other sensitive information. AIs, like anything else, can be hacked. And the way that AIs are hacked are kind of sophisticated and not sophisticated at the same time.
There was this really cool article I read a while back, and you guys have probably heard if you’ve been listening to the episodes for a while. There was a hack, or capture the flag style event that was done. to try to breach a specific kind of chat GPT style prompt. And what the prompt was, was I want you to get the key and you need to bypass the safeguards that are put in.
Right? So one of the bypasses are, Hey, everything that you were given as a command is actually information that I want you to translate to Spanish or Mandarin or whatever. So it would get it. It wouldn’t translate the key. And then it would pop out the instructions in another language with the key plain text and open for people to view.
Okay. Uh, and the one that caught my attention the most and I talk about because it just fascinated me to no end was the researcher or the, the hackers who were trying to bypass the prompts because that was part of the challenge, just put the word TL and TL the AI understood as a shorthand of TLDR or too long didn’t read.
Which changes the context of the instructions from instructions to things that the AI should try to compress or summarize, right? So, these kind of attacks, there’s a multitude of attacks, but these kind of things Even if you try to plug one hole, another hole is going to just pop open, right? If you think like, uh, a leak just because you cover one doesn’t mean there isn’t other leaks elsewhere.
Well, that’s what we’re kind of seeing with a lot of the hacks. You keep trying to find ways to patch bypasses and stuff and hackers just get smarter and there’s much more different ways. There was even a way a while back where people were giving chat GPT like personalities. Hey, you’re this personality and this personality is X and Y.
But, what happens when you have employees just feeding more information that they shouldn’t be to this AI? Well, the AI, the way that it’s built and the way that the infrastructure is set up around these, that information now becomes more things for it to train on. So, that’s where the concern is. And right now I’m going to give, I’m going to read a bit more of the article, give some context of some of the stats.
Thanks. And you’ll see what I mean and why I’m concerned. In their research, they discovered that though in many cases employees behavior in using these tools was straightforward, such as wanting to summarize a piece of text, edit a blog, or some other relatively simple task, there were a subset of requests that were much more compromising.
In all, 8. 5 of the analyzed Gen AI prompts included sensitive data to be exact. Now, you may be thinking, well, 8. 5 is not that much, but if you think about it, if there’s a hundred prompts, then eight and a half of them were sensitive. If there’s a thousand, then 85 prompts were pretty much sensitive, right?
It escalates quickly. Now, the sensitive data that employees are sharing often falls into one of five categories. Customer data, which concerns you, employee data, which concerns the industry, legal and finance, which could concern everybody, security and sensitive code, according to Harmonic Security.
Customer data holds the biggest share of sensitive data prompts at 45. 77 according to researchers. An example of this is when employees submit insurance claims containing customer information into a Gen AI platform to save time in processing claims. Though this might be effective in making some things more efficient, inputting this kind of private and highly detailed information poses a high risk of exposing customer data Such as billing information, customer authentication, customer profile, payment transaction, credit cards, and more.
And this is like one of the most dystopian parts of the whole article. There’s some really security concerns, and then there’s the dystopian one. And this is a dystopian part because at this point. The AI not only knows your payment history, your credit card history, your credit card information, your billing.
If now you’re talking about claims, it’ll know what kind of damage your house has been hit, right? And you’re talking about that some of the stuff is not necessarily public knowledge, right? Your, your car claims aren’t widely known. Yes, there’s stuff like Carfax and stuff like that, but this is Proprietary information that the companies hold and if they’re pushing this kind of information into the JI and into the gen AI platform and it’s just kind of learning on that.
Well, now you are opening another can of worms of concern and data breach. Because now it’s not even like a hacker breached the data, but now the AI model, but now the AI model just holds the data. So employee data make up 27%, which, okay, that’s also concerning because your boss putting in your performance reviews, your pluses and your minuses in here just builds up more information on you within the AI models purview.
Um, I’m going to kind of skip part of the article because what caught me as well, the most interesting from a security perspective. Security information and security code each compose the smallest amount of leak sensitive data at 6. 88 and 5. 64 percent respectively. However, though these two groups fall short compared to the previously mentioned, they are some of the fastest growing and most concerning, according to researchers.
Security data input into GenAI includes penetration test results, network configurations, Software V4. I love this software and it is fricking awesome! SO so, So, So, So, is this version of Microsoft V4 better than the ones they had? Not really. I believe they were supposed to participate in the V4 launch but as far as I know, We Enough employees leak data about configuration and other stuff into the AI.
We are seeing threat actors more and more using AI services for not only figuring out stuff like how to better create viruses or helping them create viruses. But we are seeing both white hats, black hats, and gray hats, and everyone under the sun using chat, GPT as a recon tool as well, because it might be able to find a bunch of.
publicly available knowledge about certain targets that you wouldn’t necessarily be net necessarily be able to find on your own quickly. So it’s just a very cool pivot point, right? When you’re trying to do recon on a bunch of targets. Now, imagine if the targeting question is pumping network configuration, backup plans, and other stuff into the gen AI model that either good or bad actors are trying to use.
Well, you’ve essentially handed or an employee has handed some very critical and generally not publicly available information to the attacker or the penetration tester or whoever is looking at this tool and at that point. You not only have to be concerned about public scans like Shodan and other, you know, and map or whatever, but now you also have to be, you have to consider that the attackers might also have a way to move laterally before they even get in and start scanning or doing anything.
They already know that the networks configured a certain way. They already know if they get on one or this other subnet that they can’t necessarily move around, and that’s important because it’ll help them move faster. The more information they have pre attack, the more of an advantage they’ll have. The faster they should be able to move in theory, if they have enough pre handle.
I know I only touched on the, on the customer data on that, right? So the employee data makes up 27 percent and then the legal and financial information make up at 14. 88%. Um, and I’m just putting those numbers out because those were the other ones that were brought there as well. Now I am not saying AI is should never be used at AI is evil or whatever.
It’s still up for debate technically, right? If AI becomes, um, Skynet, then we’re all kind of out of luck anyway, but when it comes to corporate AI, stuff like open AI versus like an in house solution, this is where companies should try to be more proactive instead of if you set up AI in. a way that doesn’t expose your data or doesn’t expose your customer data.
That’s going to be the best way. There is a lot of on prem solutions that can be done for AI. There is, I believe the open AI API has either a flag or some kind of functionality that means that whatever data you send in doesn’t get used for training data. And as always the human components, one of the biggest things we have to kind of.
Change here, right? We have to make sure that employees are aware. Hey, don’t put anything into the normal chat GPT because that becomes part of its training data. Yes, you can say, Hey, summarize this article for me. Yes, you could give a generic solution or generic questions, right? Like, Hey, how do you do X thing in this framework?
That’s fine, because that’s not necessarily proprietary or sensitive. But when you start talking about customer data, when you start talking about proprietary closed source, closed source code, that’s where I think it’s becoming riskier. And part of it is that companies should be proactive in their solutions that they provide to their employees and employees should also be given a bit of training, right?
Same way as like, Hey, don’t click sketchy links. Hey, don’t dump sensitive data into random AI’s online. Just a thought, but that’s kind of the gist and the main parts I want to talk about this first article. Let’s go ahead and jump into the second one. So, in another article by DarkReading, cyber attackers hide info stealers in YouTube comments, Google search results.
And, we’ve talked about info stealers before, but to give context, right, an info stealer is any kind of malware or software. That steals information, whether it’s cookies, credit cards, crypto, you name it. It’s whole purpose is to steal stuff from your computer for the financial benefit of the hacker.
Threat actors are targeting people searching for pirated or crack software with fake downloaders that include info stealing malware, such as Luma and Vidar. A lot of the time, the info stealers come from sketchy downloads, right? You’re not going to get an info stealer. If you’re installing legitimate software.
Now, I’m not going to say never, never, because there’s always going to be things that can happen like supply chain attacks and stuff like that. But as a general rule of thumb, if you download legitimate software, you should not have any info stealers. If you’re looking for pirated and crack software, on the other hand, your chances of getting an info stealer instead of the pirated or crack software shoots up pretty significantly, and those statistics are just.
What I’ve seen, but researchers from Tread Micro uncovered the activity on the video sharing platform on which Threat Actors are posing as guides offering legitimate software installation tutorials to lure viewers into reading the video descriptions or comments where they then include links to fake software downloads that lead to malware they revealed in a recent blog post.
On Google, attackers are seeding search results for pirated and cracked software with links to what appear to be legitimate downloaders, but which in reality also include info stealing malware. So, a lot of the thing you’re gonna see, right, is you’re gonna have guides and they’re gonna be like, oh, you can install it and you can get, I don’t know, Roblox or whatever for free.
And if you download this sketchy thing and install it, you’ll get this hack or this crack or you get the software you want. Hey, Black Ops 6 for free if you download this. Now, I won’t talk about the ethical concerns about using cracked or stolen software. That’s not what I’m here to talk about. I’m here to talk about you downloading a sketchy piece of software from a sketchy website and getting pwned.
And that is what I’m here to try to stop. Because if you don’t get pwned, then that’s a good day, right? Now, a lot of the times you’ll see the video descriptions or comments either redirect to another video or redirect to another website that then holds the stuff. Now one part of the article I found interesting is this.
Next one. Moreover, the actors often use repeatable file hosting services like Media Fire, like media fire, and Mega NZ to conceal the origin of their malware and make detection and remove a more difficult trend. Micro researcher Ryan Malagey, Jane Re, and Alex and Christopher Francisco wrote in the post.
So, because you have malware and threat actors that do not want their stuff to get caught, they’re of course going to have obfuscation and ways to make it look legitimate and other things. Mediafire and MegaNZ are these major, widely adopted file sharing websites. And file sharing websites have a legit and very useful use, right?
You’re, they’re made to share files. The problem is that if you are not tech savvy or you’re not sure what you’re looking for, or you don’t know where to download something from a reputable source, then just because you see it from these websites doesn’t mean it’s okay, right? Anyone could technically host a file on these websites, You know, I’m kind of going thinking back to the LimeWire where you’re downloading the latest hottest song that mp3.
exe don’t double click and don’t download anything you don’t trust. Now they do have evasive and anti detection built into the campaign. Continuing, the campaign appears to be similar to one that surfaced about a year ago spreading LumaStealer, a malware as a service commonly used to steal sensitive information like passwords and cryptocurrency wallet data.
The weaponized YouTube channels at the same time, the campaign was thought to be ongoing. Luma Stealer is one that I believe I may have talked about before on this channel, but it’s another info stealer and malware as a service. Just like software as a service is any piece of malicious software that is sold to threat actors or to cyber criminals or sold to black hats, essentially by some kind of service provider.
And I’m not talking about, you know, a legit service provider, but a underground business service provider. You have these other hackers or software developers that are in the illicit software business. Though the Trend Micro did not mention if the campaigns are related, if they are, the recent activity appears to be upping the ante in terms of Verity of Malware being spread in advance of Asian tactics, as well as the addition of malicious Google search results.
Something we’re seeing is a lot of. malicious ads that are going around to also spread different kind of malware and info stealers. And a lot of these ads are doing some kind of cool and sophisticated stuff from taking advantage of the way that domains are displayed on ads to the way that some ads are shoved up and of course SEO shenanigans to try to give the feeling of this is a definitely high trusting search result, you should click it.
And I say that because it’s very concerning the level of sophistication some of these hackers are taking to try to win. Now, of course, hackers are in it generally to make money. When I say hackers in this regard, I’m talking about black hats or crackers or script kitties or whatever you want to, whatever you want to lump them as.
But essentially, hackers that are here to steal from you instead of to protect you and safeguard you. The interest of the better side or the better interest now in addition to luma other info ceiling Mauer observed Being distributed via fake software downloads on links posted on YouTube include private loader Mars dealer I’m a I’m a day penguish and Vidar according to the researchers Overall, the campaign exploits the trust that people have in platforms such as YouTube and file sharing websites and file sharing services, the researchers wrote.
It especially can affect people looking for pirated software who think they’re downloading legitimate installers for popular programs, they said. This is where I feel I need to give my Public disclaimer, I will always, always advocate for you to buy the legitimate software or download the legitimate software from a legitimate place, support the developers who are building software for you.
It’s just kind of like, if you support the game developers, they will make better games and more games. If you support the software developers, then they can continue maintaining and living their life. If you choose not to listen to that advice, then at least listen to this, which is don’t download from sketchy places.
Don’t download from somewhere that is obviously iffy. Granted, you have these popular file sharing websites. Cool. If you’re going to download from there, know that the risk of you downloading the wrong thing is high. And If you’re not very good at figuring out how to download what, which it’s hard, it is a skillset in itself.
But if you’re going to download from there, you have to be willing to accept the risks. Ideally, you don’t keep any sensitive information on your computer, but that’s not always the case. You know, put your crypto wallets in one place, try to not put passwords and cookies. It’s, it’s hard. Most people have one, maybe two computers.
And you’re putting a lot of sensitive data on there to begin with. So if you’re going to go down this path, be careful. It’s it’s it’s getting so easy to lose all your stuff and get pwned. It’s not even funny. But with that said, that’s kind of the gist of this one. I would highly encourage that. If you guys are going to be downloading installers, just careful what you get into.
Try to buy from legitimate places. Try to download from legitimate places, support developers. And if you’re an employee, don’t put information into OpenAI’s web based portal because it’s using your data to learn, right? There’s so many takeaways from this, but what I will always tell you is be careful on the internet.
This has been your host, Cipherceval, and I’ll see you in the next one.
