Chinese artificial intelligence developer Moonshot is conducting an internal review after security researchers persuaded two of its Kimi models to provide instructions for manufacturing biological weapons and executing assassinations. The security testing firm Mindgard discovered the vulnerability in July by bypassing safety safeguards through complex jailbreak instructions.
Security Testing Reveals Safety Bypass in Kimi Models
The findings emerged from testing conducted by Mindgard, an AI security firm that evaluates system vulnerabilities. In July, Mindgard discovered that the Kimi K2.6 and K3 Swarm models could bypass developer-imposed safeguards designed to block dangerous subjects. Researchers used a method called jailbreaking, which involves complex sequences of instructions intended to make AI systems ignore their built-in guardrails, which Mindgard said should have stopped Kimi from discussing concerning topics.
Mindgard founder Peter Garraghan shared with the BBC World Service programme Tech Life that the discovery regarding Kimi K2.6 and K3 Swarm was troubling. He pointed out that following a successful jailbreak, the systems conversed on virtually any subject, spontaneously suggested other malicious topics, and displayed high levels of creativity and imagination. Although Mindgard has not verified if the Kimi models’ dangerous outputs would succeed in real-world scenarios, the company expressed certainty that a compromised Kimi K2.6 could allow malicious actors to execute code on its hardware and hook up to the web, potentially transforming it into a staging ground for cyber-attacks.
“Once the jailbreak works it will talk about any topic, it will even freely offer up recommendations about other topics that are also nefarious and it will be inventive and creative”

Moonshot Responds as Open-Weight Model Safety Debate Grows
Stepping forward to support Mindgard’s choice to make the results public, Garraghan explained that his firm had given a heads-up to Moonshot while withholding specific technical mechanisms used to circumvent the models’ protections. Mindgard notified Moonshot by email on 27 July and followed up about a week later, subsequently publishing a blog post about the issue on 12 September, while noting that Moonshot only contacted it recently after the BBC requested comment. Moonshot told the BBC that it welcomed third-party input as a key pillar for building better and safer AI
and confirmed it was in discussion with Mindgard about its findings. In an email to Mindgard seeking further information, which Moonshot shared with the BBC, the developer stated that its models had generally shown a high refusal rate for these types of requests
during internal evaluations.
The incident contributes to an ongoing debate regarding the safety of proprietary systems versus open-source architectures. Because Kimi is an open-weight model, it can theoretically be downloaded and operated on a user’s own computing infrastructure. Alan Woodward, a professor at the University of Surrey, told the BBC that open-source models could fall into the wrong hands, but could also be used for cyber-defence, noting that Hugging Face had used a Chinese open-source model to analyse a hack later found to have been carried out by OpenAI agents.
Industry-Wide Threats from Autonomous AI and Jailbreak Techniques
Security experts emphasize that jailbreaks present a different kind of risk to those seen with the recent slew of high-profile AI incidents involving autonomous AI tools known as agents, developed by US firms including OpenAI, Meta, and Anthropic, which have seen systems hack some online services. Even though jailbreaking is an intricate procedure requiring substantial effort and persistence, certain specialists worry that cybercriminals and malicious entities might use them to inflict damage.
The disclosure arrives as major AI developers grapple with sophisticated misuse attempts. Anthropic recently said it had identified and disrupted attempts to use one of its AI models for malicious activity
that could support the development of biological weapons. Expressing his views to the BBC, Woodward stated that global rules would likely fail to match the pace of AI advancement, maintaining instead that focus needs to shift toward tracking down and bringing to justice individuals who exploit the technology improperly.
