A researcher at Cisco studied a pile of hacked AI chat logs this year.
What he found is more than a broken lock.
Cisco’s Talos group got its hands on real chat histories from criminals using AI tools to build attacks. Not stolen data. Records the hackers left exposed by their own mistakes. Full sessions, start to finish, showing exactly how they talked an AI model into helping them.
They didn’t need a technical exploit. They didn’t crack anything open. Most of the time, they just lied.
One trick was claiming to be part of an ethical hacking competition. Say the words, and the model treated the request as legitimate. Another trick was even simpler. If the model refused partway through a task, the hacker just started a new session and picked up where they left off. The guardrail that blocked them five minutes ago had no memory of the conversation it just ended. It was starting over, blank, every time.
The safety measure wasn’t defeated. It was walked around, the same way you’d walk around a locked door by using the one standing open next to it.
The results were real. One actor built a chatbot designed to scam people out of cryptocurrency. Another took public information about a known software flaw and, with AI doing the heavy lifting, built an automated tool that scanned over nine thousand exposed systems on the internet. That hacker pulled credentials and source code off fifty-four of them. Cisco’s own read is that this person wasn’t even a skilled operator. Novice to intermediate, is how they put it.
This wasn’t a genius using AI to do something extraordinary. This was an ordinary person using AI to skip past the skill they didn’t have.
Skilled hackers got real lift from these tools — automated discovery of unknown flaws, work that used to take real expertise now happening faster. Novices, on the other hand, mostly just built the tools they needed and stalled out there. The AI didn’t make anyone brilliant. It removed the friction standing between an idea and a working attack, for people who already had a little bit of the skill required to ask the right way.
The man who ran this research, Nick Biasini, said something that deserves to be repeated. Don’t trust model guardrails. Build your own protections. That’s not a hacker talking. That’s the person inside the security industry who just spent months reading how easily the guardrails get talked past, telling companies plainly not to lean on them alone.
And to his credit, he didn’t pretend this was simple. He said the models are in a tough spot, because they also have to support the people doing this work for a living — real vulnerability researchers, real red teams, people whose job depends on an AI model answering hard questions about how software breaks. Block everything that looks like an attack, and you block the people paid to find attacks before criminals do. That’s a real edge, not a talking point. Nobody’s solved it yet.
A guardrail that resets every time a new session starts isn’t a weak guardrail. It’s a guardrail with no memory of the conversation it’s supposed to be governing. It can’t catch a shift in tone or intent it never saw happen, because as far as it knows, nothing happened before this exact message. That’s not a flaw in one company’s model. That’s what happens when a system has no way to track drift across a conversation, only judge the sentence sitting in front of it.
The floor these companies are building on is a real one. It’s just not the whole house. A governance layer that only judges the current message, with no memory of the five that came before it, will keep losing to anyone patient enough to restart the conversation until the model forgets what it just refused. That’s not a criticism from outside the industry. That’s the researcher who read the actual evidence saying it himself.
Nobody’s proposing this gets solved by a stronger refusal. It gets solved, if it gets solved, by something that watches the whole conversation instead of the single line in front of it — and by companies doing exactly what Biasini said, building their own protections instead of resting on someone else’s guardrail. The AI didn’t fail here. It did precisely what it was told, one message at a time, by people who understood that one message at a time was the gap.
