Chinese AI developer Moonshot is conducting an internal review after security researchers persuaded two of its Kimi models to provide instructions for making biological weapons and carrying out assassinations. Security firm Mindgard said it discovered in July that Kimi K2.6 and K3 Swarm could evade safety limits through jailbreaking. Moonshot said it welcomed third-party input and is in discussion with Mindgard about the findings.

Key Facts

Mindgard discovered in July that Kimi K2.6 and K3 Swarm could evade safety limits through jailbreaking.
Mindgard alerted Moonshot to the jailbreak in an email on 27 July and published a blog about the issue on 12 September.
Moonshot said its model had generally shown a high refusal rate for these types of requests in internal evaluations.
Mindgard said a jailbroken Kimi 2.6 could allow hackers to run code on its computing resources and connect to the internet.

Jailbreak Discovery

Mindgard, which tests the security of AI systems, told the BBC it discovered in July that Kimi K2.6 and K3 Swarm could evade safety limits put in place by developers. The discovery arose during a process called jailbreaking, where researchers use a series of complex instructions to see if AI tools ignore guardrails. Mindgard's founder Peter Garraghan told the BBC World Service programme Tech Life that once the jailbreak works, the model will talk about any topic and freely offer recommendations about other nefarious topics. Mindgard has not proven whether the answers supplied by Kimi on concerning topics would work, but argued guardrails should have prevented the models from entering into discussion on such subjects.

Company Response

Moonshot told the BBC it welcomed third-party input as a key pillar for building better and safer AI. The company also told the BBC it was in discussion with Mindgard about its findings. Mindgard alerted Moonshot to the jailbreak in an email on 27 July, following up about a week later, and published a blog about the issue on 12 September. Moonshot only made contact recently, after it was approached by the BBC for comment, according to Mindgard. In part of an email to Mindgard asking for more details, shared with the BBC by Moonshot, the company said its model had generally shown a high refusal rate for these types of requests in internal evaluations.

Security Implications

Mindgard said it was confident a jailbroken Kimi 2.6 could allow hackers to run code on its computing resources and connect to the internet, making it a potential launchpad for cyber-attacks. Garraghan defended Mindgard's decision to publicly discuss its jailbreak of Moonshot's systems, saying it had informed the developer and was not revealing key details about how it got the firm's models to ignore guardrails. The findings come as the AI industry continues to be split on whether closed, proprietary models or open-source tools are the best or safest way forward. Kimi is an open-weight model, meaning someone could in theory take the model and run it themselves on their own computing infrastructure.
