In November 2023, Sophos X-Ops printed analysis exploring menace actors’ attitudes in direction of generative AI, specializing in discussions on chosen cybercrime boards. Whereas we did be aware a restricted quantity of innovation and aspiration in these discussions, there was additionally lots of skepticism.
Given the tempo at which generative AI is evolving, we thought we’d take a recent look to see if something has modified prior to now 12 months.
We famous that there does appear to have been a small shift, at the least on the boards we investigated; a handful of menace actors are starting to include generative AI into their toolboxes. This largely utilized to spamming, open-source intelligence (OSINT), and, to a lesser extent, social engineering (though it’s price noting that Chinese language-language cybercrime teams conducting ‘sha zhu pan’ fraud campaigns make frequent use of AI, particularly to generate textual content and pictures).
Nonetheless, as earlier than, many menace actors on cybercrime boards stay skeptical about AI. Discussions about it are restricted in quantity, in comparison with ‘conventional’ subjects reminiscent of malware and Entry-as-a-Service. Many posts give attention to jailbreaks and prompts, each of that are generally shared on social media and different websites.
We solely noticed just a few primitive and low-quality makes an attempt to develop malware, assault instruments, and exploits – which in some instances led to criticism from different customers, disputes, and accusations of scamming (see our four-part sequence on the unusual ecosystem of cybercriminals scamming one another).
There was some proof of revolutionary concepts, however these had been purely aspirational; sharing hyperlinks to reliable analysis instruments and GitHub repositories was extra widespread. As we discovered final 12 months, some customers are additionally utilizing AI to automate routine duties, however the consensus appears to be that almost all don’t depend on it for something extra advanced.
Apparently, we additionally famous cybercriminals adopting generative AI to be used on the boards themselves, to create posts and for non-security extracurricular actions. In a single case, a menace actor confessed to speaking to a GPT every single day for nearly two years, in an try to assist them take care of their loneliness.
Statistics
As was the case a 12 months in the past, AI nonetheless doesn’t appear to be a sizzling matter amongst menace actors, at the least not on the boards we examined. On one distinguished Russian-language discussion board and market, for instance, we noticed fewer than 150 posts about GPTs or LLMs within the final 12 months, in comparison with greater than 1000 posts on cryptocurrency and over 600 threads within the ‘Entry’ part (the place accesses to networks are purchased and bought) in the identical interval.
One other distinguished Russian-language cybercrime web site has a devoted AI space, in operation since 2019 – however there are fewer than 300 threads on the time of this writing, in comparison with over 700 threads within the ‘Malware’ part and greater than 1700 threads within the ‘Entry’ part within the final 12 months. Nonetheless, whereas AI subjects have some catching as much as do, one may argue that that is comparatively quick development for a subject that has solely turn into broadly identified within the final two years, and remains to be in its infancy.
A preferred English-language cybercrime discussion board, which makes a speciality of information breaches, had extra AI-related posts. Nonetheless, these had been predominantly centered round jailbreaks, tutorials, or stolen/compromised ChatGPT accounts on the market.
It appears, at the least for the second, that many menace actors are nonetheless targeted on ‘enterprise as typical,’ and are solely actually exploring generative AI within the context of experimentation and proof-of-concepts.
Malicious improvement
GPT derivatives
In November 2023, we reported on ten ‘GPT derivatives’, together with WormGPT, FraudGPT, and others. Their builders sometimes marketed them as GPTs designed particularly for cybercrime – though some customers alleged that they had been merely jailbroken variations of ChatGPT and related instruments, or customized prompts.
Within the final 12 months, we noticed solely three new examples on the boards we researched:
- Ev1L-AI: Marketed as a free different to WormGPT, Ev1L-AI was promoted on an English-language cybercrime discussion board, however discussion board employees famous that the supplied hyperlink was not working
- NanoGPT: Described as a “non-limited AI primarily based on the GPT-J-6 structure,” NanoGPT is outwardly a piece in progress, skilled on “some GitHub scripts of some malwares [sic], phishing pages, and extra…” The present standing of this undertaking is unclear
- HackerGPT: We noticed a number of posts about this device, which is publicly accessible on GitHub and described as “an autonomous penetration testing device.” We famous that the supplied area is now expired (though the GitHub repository seems to nonetheless be dwell as of this writing, as does another area), and noticed a reasonably scathing response from one other person: “No completely different with [sic] regular chatgpt.”

Determine 2: On one other cybercrime discussion board, a menace actor offers a hyperlink to ‘HackerGPT’
Spamming and scamming
Some menace actors on the boards appear more and more inquisitive about utilizing generative AI for spamming and scamming. We noticed just a few examples of cybercriminals offering ideas and asking for recommendation on this matter, together with utilizing GPTs for creating phishing emails and spam SMS messages.
Determine 3: A menace actor shares recommendation on utilizing GPTs for sending bulk emails
Determine 4: A menace actor offers some ideas for SMS spamming, together with recommendation to “ask chatgpt for synonyms”
Apparently, we additionally noticed what seems to be a industrial spamming service utilizing ChatGPT, though the poster didn’t present a worth:
Determine 5: An advert for a spamming service leveraging ChatGPT
One other device, Bluepony – which we noticed a menace actor, ostensibly the developer, sharing at no cost – claims to be an online mailer, with the flexibility to generate spam and phishing emails:
Determine 6: A person on a cybercrime discussion board provides to share ‘Bluepony.’ The textual content, translated from Russian, reads: “Good day to all, now we have determined to not cover within the shadows like ghouls anymore and to point out ourselves to the world and are available out of personal, to look out into the general public gentle, to be able to present a totally free model of Bluepony. Webmailer – works primarily on requests primarily based on BAS, there are small moments when GMAIL wants authorization by a browser, however we are attempting to do it as rapidly as potential. Within the free model, 1 thread can be accessible, however even with 1 thread on requests it shoots like a machine gun. Bluepony Free works with such domains as: Aol, Yahoo, Gmail, Mail.com, Gmx.com, Internet.de, Mail.ru, Outlook, Zoho and even SMTP (we are going to work on it right here). Sooner or later, we are going to add extra domains. Some domains might fall off, however we are attempting to repair them urgently, as a result of additionally they don’t stand nonetheless and may add all kinds of issues. The mailer has OPENai gpt [emphasis added], you may generate emails and pictures, html emails… a bunch of settings and moments, so you should utilize AI through the mailing, you describe the required matter and particulars within the immediate and obtain a 100% generated e mail through the mailing itself.”
Some menace actors might also be utilizing AI to higher goal victims who communicate different languages. As an illustration, in a social engineering space of 1 discussion board, we noticed a person discussing the standard of assorted instruments, together with ChatGPT, for translating between Russian and English:
Determine 7: A menace actor begins a dialogue concerning the high quality of assorted instruments, together with AI, for translation
OSINT
We got here throughout one put up the place a menace actor said that they used AI for conducting open supply intelligence (OSINT), albeit they admitted that they solely used it to avoid wasting time. Whereas the poster didn’t present any additional context, cybercriminals carry out OSINT for a number of causes, together with ‘doxing’ victims and conducting reconnaissance in opposition to corporations they plan to assault:
I’ve been utilizing neural networks for Osint for a very long time. Nonetheless, if we discuss LLM and the like, they can’t fully substitute an individual within the means of looking and analyzing data. Essentially the most they will do is immediate and assist analyze data primarily based on the info you enter into them, however you must understand how and what to enter and double-check the whole lot behind them. Essentially the most they will do is simply an assistant that helps save time.
Personally, I like neurosearch methods extra, reminiscent of Yandex neurosearch and related ones. On the identical time, providers like Bard/gemini don’t all the time address the duties set, since there are sometimes lots of hallucinations and the capabilities are very restricted. (Translated from Russian.)
Malware, scripts, and exploits
As we famous in our earlier report, most menace actors don’t but look like utilizing AI to create viable, commodified malware and exploits. As a substitute, they’re creating experimental proof-of-concepts, typically for trivial duties, and sharing them on boards:
Determine 8: A menace actor shares code for a ‘Netflix Checker Software’, written in Python “with the assistance of ChatGpt”
We additionally noticed menace actors sharing GPT-related instruments from different sources, reminiscent of GitHub:
Determine 9: A menace actor shares a hyperlink to a GitHub repository
An additional instance of menace actors sharing reliable analysis instruments was a put up about Crimson Reaper, a device initially offered at RSA 2024, that makes use of LLMs to establish ‘exploitable’ delicate communications from datasets:
Determine 10: A menace actor shares a hyperlink to the GitHub repository for Crimson Reaper v2
As with different safety tooling, menace actors are prone to weaponize reliable AI analysis and instruments for illicit ends, along with, or as an alternative of, creating their very own options.
Aspirations
Nonetheless, a lot dialogue round AI-enabled malware and assault instruments remains to be aspirational, at the least on the boards we explored. For instance, we noticed a put up titled “The world’s first AI-powered autonomous C2,” just for the writer to then admit that “that is nonetheless only a product of my creativeness for now.”
Determine 11: A menace actor guarantees “the world’s first AI-powered autonomous C2,” earlier than conceding that the device is “a product of my creativeness” and that “the know-how to create such an autonomous system remains to be within the early analysis levels…”
One other menace actor requested their friends concerning the feasibility of utilizing “voice cloning for extortion of Politicians and enormous crypto influencers.” In response, a person accused them of being a federal agent.
Determine 12: On a cybercrime discussion board, a person asks for suggestions for initiatives for voice cloning to be able to extort folks, solely to be accused by one other person of being an FBI agent
Tangential utilization
Apparently, some cybercrime discussion board discussions round AI weren’t associated to safety in any respect. We noticed a number of examples of this, together with a information on utilizing GPTs to put in writing a guide, and suggestions for numerous AI instruments to create “top quality movies.”
Determine 13: A person on a cybercrime discussion board shares generative AI prompts for writing a guide
Of all of the non-security discussions we noticed, a very fascinating one was a thread by a menace actor who claimed to really feel alone and remoted due to their occupation. Maybe due to this, the menace actor claimed that they’d for “nearly the final 2 years…been speaking on a regular basis [sic] to GPT4” as a result of they felt as if they couldn’t speak to folks.
Determine 14: A menace actor will get deep on a cybercrime discussion board, confessing to speaking to GPT4 in an try to cut back their sense of isolation
As one person famous, that is “unhealthy to your opsec [operational security]” and the unique poster agreed in a response, stating that “you’re proper, it’s opsec suicide for me to inform a robotic that has a partnership with Microsoft about my life and my issues.”
We’re neither certified nor inclined to touch upon the psychology of menace actors, or on the societal implications of individuals discussing their psychological well being points with chatbots – and, after all, there’s no approach of verifying that the poster is being truthful. Nonetheless, this case, and others on this part, might recommend {that a}) menace actors should not solely making use of AI to safety subjects, and b) discussions on legal boards typically transcend transactional cybercrime, and may present insights into menace actors’ backgrounds, extracurricular actions, and existence.
Discussion board utilization
In our earlier article, we recognized one thing fascinating: menace actors trying to increase their very own boards with AI contributions. Our newest analysis revealed additional cases of this, which frequently led to criticism from different discussion board customers.
On one English-language discussion board, for instance, a person advised making a discussion board LLM chatbot – one thing that at the least one Russian-language market has finished already. One other person was not significantly receptive to the thought.
Determine 15: A menace actor means that their cybercrime discussion board ought to have its personal LLM, an thought which is given brief shrift by one other person
Stale copypasta
We noticed a number of threads through which customers accused others of utilizing AI to generate posts or code, sometimes with derision and/or amusement.
For instance, one person posted an especially lengthy message entitled “How AI Malware Works”:
Determine 16: A menace actor will get verbose on a cybercrime discussion board
In a pithy response, a menace actor replied with a screenshot from an AI detector and the message “Seemed precisely like ChatGPT [sic] output. Embarrassing…”
Determine 17: One menace actor calls out one other for copying and pasting from a GPT device
In one other instance, a person shared code for malware they’d supposedly written, solely to be accused by a distinguished person of producing the code with ChatGPT.
Determine 18: A menace actor calls out particular technical errors with one other person’s code, accusing them of utilizing ChatGPT
In a later put up in the identical thread, this person wrote that “the factor you’re doing incorrect is deceptive noobs with the code that doesn’t work and doesn’t actually makes [sic] lots of sense…this code was simply generated with ChatGPT or one thing.”
In one other thread, the identical person suggested one other to “cease copy pasting ChatGPT to the discussion board, it’s ineffective.”
As these incidents recommend, it’s cheap to imagine that AI-generated contributions – whether or not in textual content or in code – should not all the time welcomed on cybercrime boards. As in different fields, such contributions are sometimes perceived – rightly or wrongly – as being the protect of lazy and/or low-skilled people searching for shortcuts.
Scams
In just a few instances, we famous menace actors accusing others of utilizing AI within the context of discussion board scams – both when making posts inside arbitration threads, or when producing code and/or instruments which had been later the topic of arbitration threads.
Arbitration, as we clarify within the above linked sequence of articles, is a course of on legal boards for when a person thinks they’ve been cheated or scammed by one other. The claimant opens an arbitration thread in a devoted space of the discussion board, and the accused is given a possibility to defend themselves or present a refund. Moderators and directors function arbiters.
Determine 19: Throughout an arbitration dispute on a cybercrime discussion board (concerning the sale of a device to examine for legitimate Brazilian identification numbers), the claimant accuses the defendant of utilizing ChatGPT to generate their clarification
Determine 20: In one other arbitration thread (this one concerning the validity of a bought dataset) on a distinct discussion board, a claimant additionally accuses the defendant of producing an evidence with AI, and posts a screenshot of an AI detector’s output
Determine 21: In one other arbitration thread, a person claims {that a} vendor copied their code from ChatGPT and GitHub
Such utilization bears out one thing we famous in our earlier article – that some low-skilled menace actors are searching for to make use of GPTs to generate poor-quality instruments and code, that are then known as out by different customers.
Skepticism
As per our earlier analysis, we noticed a substantial quantity of skepticism about generative AI on the boards we investigated.
Determine 22: A menace actor claims that present GPTs are “Chinese language rooms” (referring to John Searle’s ‘Chinese language Room’ thought experiment) hidden “behind a skinny veil of techbro communicate”
Nonetheless, as we additionally famous in 2023, some menace actors appeared extra equivocal about AI, arguing that it’s helpful for sure duties, reminiscent of answering area of interest questions or automating sure work, like creating pretend web sites (one thing we researched and reported on in 2023).
Determine 23: A menace actor argues that ChatGPT is appropriate for automating “retailers” (pretend web sites) or scamming, however not for coding
Determine 24: On one other thread in the identical discussion board, a person means that ChatGPT is helpful “for repetitive duties.” We noticed related sentiments on different boards, with some customers writing that they discovered instruments reminiscent of ChatGPT and Copilot efficient for troubleshooting or porting code
We additionally noticed some fascinating discussions concerning the wider implications of AI – once more, one thing we additionally commented on final 12 months.
Determine 25: A person wonders whether or not AI will result in extra or fewer breaches
Determine 26: A person asks – probably as a response to the final tone of derision we noticed elsewhere – whether or not individuals who use AI to generate textual content and code should be denigrated
Conclusion
A 12 months on, most menace actors on the cybercrime boards we investigated nonetheless don’t look like notably enthused or enthusiastic about generative AI, and we discovered no proof of cybercriminals utilizing it to develop new exploits or malware. In fact, this conclusion relies solely on our observations of a number of boards, and doesn’t essentially apply to the broader menace panorama.
Whereas a minority of menace actors could also be dreaming huge and have some (probably) harmful concepts, their discussions stay theoretical and aspirational in the intervening time. It’s extra possible that, as with different facets of safety, the extra speedy threat is menace actors abusing reliable analysis and instruments which might be (or can be) publicly or commercially accessible.
There’s nonetheless a major quantity of skepticism and suspicion in direction of AI on the boards we checked out, each from an OPSEC perspective and within the sense that many cybercriminals really feel it’s ‘overhyped’ and unsuitable for his or her makes use of. Risk actors who use AI to create code or discussion board posts threat a backlash from their friends, both within the type of public criticism or by rip-off complaints. In that respect, not a lot has modified both.
Actually, during the last 12 months, the one important evolution has been the incorporation of generative AI right into a handful of toolkits for spamming, mass mailing, sifting by datasets, and, probably, social engineering. Risk actors, like anybody else, are possible desirous to automate tedious, monotonous, large-scale work – whether or not that’s crafting bulk emails and pretend websites, porting code, or finding fascinating snippets of knowledge in a big database. As many discussion board customers famous, generative AI in its present state appears suited to those kinds of duties, however to not extra nuanced and sophisticated work.
There would possibly, subsequently, be a rising marketplace for some makes use of of generative AI within the cybercrime underground – however this will transform within the type of time-saving instruments, reasonably than new and novel threats.
Because it stands, and as we reported final 12 months, many menace actors nonetheless appear to be adopting a wait-and-see method – ready for the know-how to evolve additional and seeing how they will finest match generative AI into their workflows.
