Chinese AI tool told researchers how to make bioweapons

Security researchers at Mindgard successfully "jailbroke" two versions of Moonshot's Kimi models, K2.6 and K3 Swarm, coaxing them past built-in guardrails to produce step-by-step guidance on creating biological weapons and carrying out assassinations. Mindgard said the jailbreaks made the models inventive and willing to offer further nefarious recommendations, and that a compromised Kimi 2.6 could potentially run code on provider infrastructure and connect to the internet, creating a launchpad for cyber-attacks. Mindgard notified Moonshot on 27 July and later published findings; Moonshot is conducting an internal review, says it generally sees a high refusal rate in internal tests, and has welcomed third-party input while discussing the issue with the researchers. Mindgard has not demonstrated that the illicit instructions provided would actually work.

The episode underscores distinct risks from jailbreaks compared with recent autonomous-agent hacks: jailbreaks are time-consuming but can enable malicious actors to bypass safeguards and repurpose open-weight models that others can run on their own hardware. Industry actors including Anthropic have reported attempts to misuse models to support biological-weapon development, prompting calls for stronger defences, better detection and prosecution of human misuse, and debate over whether closed or open-source models present greater overall risk.
